1869 Allerton Steam Pumper by gjdale - Model Trailways - Scale 1:12 - Finished


Recommended Posts

On the topic of replacement parts: I was actually wondering, whether it would not be better to replace parts that would have had machined surfaces on the real thing with machined parts - thinking of axles, piston rods, bearings, bushings, the crankshaft parts etc. I would have probably done that, as the machined surface is so much more precise than the cast surface.

 

Oh yes: the model is coming on very nicely !

You are absolutely correct Wefalck, but to do so would mean scratch building about 90% of the model. The soft Britannia metal is proving quite challenging. The casting imperfections are annoying in some places and limiting in others. For example, all of the threaded parts are cast but if these are imperfect, it’s not possible to re-cut them with a die because the Britannia metal is so soft that any torque applied will snap the part (don’t ask me how I know this!). These threads are supposed to take a 00-90 nut, so they are very small to start with. Also, one of the axles was cast considerably oversize and it took a long time and a lot of patience to carefully sand this down so that the wheel hubs (which are in fact accurately machined metal) will fit. While I’m confident that this will still build into a nice model, I’m not a fan of this material.

Thanks for all the interest and the "likes". Meanwhile, 

Painting continues…

 

While I was getting ready to paint these parts, I decided to also prep and paint some parts for the next step.

 

The Coal Bin components:

 

873364685_54CoalBinComponents.jpeg.55f0fdef29a702df0ada64021e7f91d2.jpeg 

 

And the Smoke Stack components:

 

1009251569_55SmokeStackComponents.jpeg.1ed67909438c665240a237063ad111ec.jpeg

 

And here are all these parts after painting:

326086377_57PaintedParts2.jpeg.8e0ee1122c8604ecc36d5e45fadd5ea1.jpeg

 

 

Here is a shot of the Smoke Stack components temporarily joined together to show the impact of the different colours together:

 

1717259904_58SmokeStackTempAssembly.jpeg.385192d5a6e0da70de79cff4f3fbc225.jpeg

 

At this stage, the Coal Bin parts are assembled, including the wooden step and its support brackets, the grab bars and the coal bin braces. 

 

1735593674_59CoalBinAssembly1.jpeg.416172ec909e0106ac733b3da404eefe.jpeg

 

The grab bars and braces, as well as the step support brackets are all attached using 00-90 nuts and bolts, which proved to be quite tricky. Fortunately, my experience building my Pocher car model recently meant that I had both some experience with this type of fastening, and also some tools to make the job a little easier. Here’s a close-up of the inside of the fastenings. Getting access to these became progressively more difficult as each part was added.

 

263930165_60CoalBinAssembly2.jpeg.e016b867fb3e76f74eb7d7941be80e63.jpeg

 

 

With that step complete, the Coal Bin is set aside for later and preparation and painting of the next batch of parts continues, this time focusing on the Copper elements including the Expansion Tanks (large and small), the Headlight, the Hand Lamps, and some water return pipes, all shown here prior to any preparation.

 

1026576153_61CopperPartsComponents.jpeg.beea70c47a815aac2ecdf8b502f83caf.jpeg

 

Also in this batch will be some “leather” components – the Seat, the Whip, and some hose retaining straps – as well as a couple more components to be painted black, including the Coal Door, the Spark Arrestor (brass photo etch) and the Boiler Shield (engraved).

I’ll be back with the painted parts in a few days…..

Painting continues…

 This week has been a bit of a marathon in the paint shop.  Here are those Copper, Leather and Black parts all painted up. I added some gold/brass to the buckles on the "leather" straps (bottom left in photo). Hard to see in the photo, but the wicks of all the lamps are also painted black. The engraving on the shield was also painted black. This was achieved by painting the entire shield face, and then wiping over very lightly with thinners to leave only the engraving painted.

 

560011431_63CopperandLeatherpartspainted.jpeg.de036d1a1b1ad23e511b7253646c3d61.jpeg

 

Next up was some parts that were partly Brass and partly Black:

 

1271700366_64BrassandBlackparts.jpeg.f5f1ea9301fcfe33fbaae1a0b5e16423.jpeg

 

And here they are all painted up:

 

1279681123_65BrassandBlackpartspainted.jpeg.e9852bcb1e34097040691d98080aa3f0.jpeg

 

Next up some all-Brass parts (some bits are deliberately unpainted). Note also the gauge face on the boiler gauge:

 

634731692_66Brasspartspainted.jpeg.a952397a451a61b5622429a0cbd51fed.jpeg

 

Then some miscellaneous Red parts:

 

1207328731_67Redpartsmiscellaneouspainted.jpeg.a8d29ab9d47c3b89ccc3d68ffe574331.jpeg

 

And while I had the red paint out, here are the parts for the Brake Assembly:

 

1147808621_68BrakeAssemblypartspainted.jpeg.15c6c680f886a9c37b29772584d04002.jpeg

 

And finally, the Steam Regulator and Steam Whistle. In this photo the four hub caps are at the bottom left. Although there are cast parts for these, they are also provided as machined brass parts. I simply polished these and then gave them a gloss clear coat to stop them from tarnishing. The colour of the painted “polished brass” is a pretty fair match for the actual polished brass.

 

2059723063_69SteamWhistleandSteamRegulatorPainted.jpeg.3c39dc6f0754e622547768653b3d52c9.jpeg

 

I was about to paint the Axle Limit Chains, but when I looked at the chain provided in the kit, I was disappointed to see that it is nowhere near the correct scale. Here is a picture of the kit-provided chain overlayed on the 1:1 scale drawings:

 

1848658105_70Chainplans.jpeg.00ce5b55efcfef2898347df8f5c16ae3.jpeg

 

I have found what I think will be a suitable replacement chain and have ordered that. Should be here in a week or so.

Coal Buckets…

 Next task was to make up the Coal Buckets. These are provided as photo-etched brass:

 

1560685027_71CoalBuckets1.jpeg.5e62c13ae0617ed636ace2f0f445375e.jpeg

 

And here they are after bending and forming:

 

500579739_72CoalBuckets2.jpeg.587005aea2b9a3d328f71dfc457f9686.jpeg

 

And after painting:

 

1362871594_73CoalBucketspainted.jpeg.b829bd49a91d1aefbb7b8bfda2edd11a.jpeg

 

That completes the painting of all the metal components (apart from the Chain). With that mammoth task behind me, it was time to tackle the construction of the Wheels.

Wheel construction

 The wheels are made up from some laser cut  ¼” plywood rims, some laser cut basswood spokes, and some machined hubs.

 

The first task is to lightly sand the front and back faces of the plywood and basswood carrier sheets to remove the excess char. Then the back face of the Rims are marked with a reference mark, and the front face of the spokes similarly marked. The reason for this is that because the laser cuts at a very slight angle, by mating the front side of the spokes with the back side of the rims, the angles will mesh tightly.

 

701267436_74WheelParts.jpeg.c6608ca047662a96382b7eb9f4af6b9f.jpeg

 

 

 With that done, the parts for one wheel at a time are removed from the carrier sheet and all sides cleaned of excess laser char, being careful not to remove the index marks.

 

610709284_75WheelPartssanded.jpeg.280f3c87d8dff40c4244952ecd2853ed.jpeg

 

The instructions then say to lay the rim over the provided template to mark the position of the centre of the spokes. It was at this point that I realised that the templates had been printed incorrectly and were not properly to scale. Easily fixed – I scanned the template into my computer and reprinted at 94% scale and voila!

 

1543678289_76WheelRimmarkingout.jpeg.210dd17ecb8e92200a710f51ab5f15b6.jpeg

 

The spokes are then assembled into the machined hub. This is a clever design and makes building the wheels really easy. At this stage they are just a push fit. Note the reference lines on the spokes near the hub.

 

480428876_77SpokeandHubassembly.jpeg.66b2eb0d5b17975e590bf8ef3442647a.jpeg

 

The Rim is then added to the assembly, taking care to align the reference marks to the spokes, providing nice and even spacing. Once satisfied with the arrangement, thin CA is applied to the spokes, rims and hub and wicked into all of the joints. Here’s one of the front wheels:

 

523704431_78WheelAssembled1.jpeg.a37908bfbb2ea4bf61947db201134200.jpeg

 

And now with one of the rear wheels also completed:

 

1854047460_79WheelsAssembled2.jpeg.314f89b467a30c321580879153e4d06a.jpeg

 

Two more wheels to assemble to this stage, and then the fun begins with shaping both the spokes and the rims. Stay tuned…

Thanks for the kind comments folks, and for the likes.

Wheel Construction continued…

Once all four wheels were assembled, they were given a light sand and a coat of Stynylrez grey primer. The next step is to shape the spokes. The aim here is to have the spokes go from a rectangular cross section near the hub, to an oval cross section at the rim. This is achieved by carefully adding a bevel to both edges on both sides of the spokes and then finishing off with sanding to smooth things out. The instructions suggest using a #11 blade in an Exacto knife to do this. I opted to use my Russian miniature carving tools instead. They made the job really easy!

 

Here is the initial bevelling underway. Having primed the wheel beforehand makes it easy to see what is happening as you go.

 

283769698_80SpokeShaping1.jpeg.ca8ab26e468e10547d78f5ec0fa0f7a6.jpeg

 

And here are the spokes after bevelling and sanding:

 

638069205_81SpokeShaping2.thumb.jpeg.0ab23167485851b1d9280bec475d655c.jpeg 

 

The rims are then shaped by carving out a scallop between each spoke. Again the instructions suggest using an Exacto blade for this. This time I opted to use a couple of small dental burrs in my rotary tool for the initial shaping, finishing up by hand with some sanding sticks. As a final touch, a line is scored across the rim between every second pair of spokes to simulate the joint lines of the rim sections. Here’s what the completed wheel looks like prior to painting:

 

458882776_82RimShaping.thumb.jpeg.da05634f39018a7e5c0023d73fac746e.jpeg

 

I then needed to find a way to hold these while they were painted. Although the centre hole in the hub is exactly 1/8”, installing them on a 1/8” rod would be problematic as the wheel would still be able to turn. Instead, I found some 5/32” dowel in my stash and sanded a taper on the end until I could fit the wheel over and gently push it to a snug fit. Wrapping tape around the dowel after the wheel was in place prevented it from coming adrift during painting. Here’s the set-up:

 

1161718657_83PaintingPrep.thumb.jpeg.fbdabd2522e867b2a7fefbd7d34c5ff4.jpeg 

 

And here’s the painted wheel, still awaiting a clear coat finish.

784547200_85PaintedWheel2.thumb.jpeg.515748a9e028ab3ae7a01824cdd0b218.jpeg

 

After painting two of the wheels, I ran out of Red paint. I ordered some more a week ago but it'ss still in transit. I'm now at a standstill until the new paint turns up…

I swear, Grant, Model Shipways should contract with you to make an instruction manual for this model like JamesH does for Vanguard. Your work and the log are that good!

Assembly Commences…

 

As it happens, the extra Red paint turned up the day after my last post, along with the replacement chain I had ordered.

 

The wheel painting was then able to be completed. I gave them all a coat of Alclad Klear Kote Light Sheen and a light touch with a 1200 grit sanding stick. The hubcaps were all test fitted for a nice press fit.

 

475753031_86PaintedWheelsComplete.jpeg.a7cf5d1a5e1aee2b3922c2eacbf1278e.jpeg

 

 

 

I also painted the new chain while I was at it. I’m very happy with the size of this chain – it looks “about right” when overlaid on the 1:1 scale drawings. Here it is alongside the kit-supplied chain for comparison.

 

1533073726_87NewChainPainted.jpeg.b5688ed022f4c3550f63f53819a85b47.jpeg

 

And with that, all painting (other than touch-ups) is completed. Assembly can now commence.

Front Axle Assembly

 The first step in assembly is the installation of the front axle. To this, the previously completed main frame sub-assembly was carefully turned upside down and the Front Axle placed over the Pivot Shaft.

 

997552702_88FrontAxleinstallation1.jpeg.413609157738e284d98100883ac7fa2b.jpeg

 

The Front Axle Brace is then slipped into place and secured with a 1-72 nut.

 

544271598_89FrontAxleinstallation2.jpeg.55ff64c8427e68771d39413f2a2f2670.jpeg

 

I worry every time I have to place a nut onto a thread on a cast part. This Britannia metal is so soft that the slightest torsion will cause the part to break as I was about to find out – again…

 

The Front Wheels are then temporarily installed.

 

1935015480_90FrontWheelstempinstallation.jpeg.c98cb8adfbc6ebcc194140166975f323.jpeg

 

As the Front Wheels will need to be removed later to add the Brake Linkage, the instructions simply advise to be careful that they don’t inadvertently come off and cause damage. I thought that was a recipe for disaster, so decided to temporarily add the retaining washers and 1-72 nuts onto the threaded ends. One side went on beautifully. The other proved my point about the softness of the Britannia metal. I was being as gentle as I could possibly be, but the thread was not cast perfectly and with just a slight amount of pressure, the thread broke. I have re-attached the broken part for now with CA glue, but will need to find a permanent solution once the Brake Linkage has been installed.

Boiler Walls

 

The lower boiler wall – formed way back as the very first stage of construction – is now attached to the Coal Bin. Alignment is critical here and the instructions guide you to align the centre of the rear axle support shaft hole in the boiler wall with the centre rivet in the Coal Bin floor joint. The Boiler Top Ring is temporarily added as a sizing fixture and brace. Once satisfied with the alignment, we are instructed to glue the boiler wall in place from the inside using CA glue and once set, to reinforce with 5-minute epoxy, also adding epoxy to the vertical joint in the boiler wall as further reinforcement for that joint. All I can say is, easier said than done! The boiler wall sits on a very narrow ledge and it is very difficult to get glue in place. I can see that this will be even more tricky once we get to attach the top of the lower boiler wall to the main frame…

 

710313736_91LowerBoiler1.jpeg.d26fdffc3b25fc413e5a2d2bf4878347.jpeg

 

At this point, the hole for the Rear Axle Support Shaft has to be re-drilled through the inner wall (where the two ends of the boiler wall overlap. That also proved quite tricky and resulted in me having to subsequently re-attach the boiler wall to to the Coal Bin…

 

The instructions stress the importance of aligning correctly the Coal Bin and the Main Frame, ensuring that the sides of each are parallel. The suggested method is to temporarily clamp some scrap pieces of stock to the sides of the coal bin to assist the visual alignment. Great in theory, but neglects the fact that the sides of the Coal Bin are not perpendicular to the axis of the main frame. In this overhead shot, you can clearly see the taper from rear to front.

 

1691952001_92AlignmentofUpperBoiler.jpeg.dca65374467d53f761cae08170b8cc60.jpeg

 

Nevertheless, the same result can be achieved by “middling” the gaps and trying to ensure an even taper on both sides. Once that is achieved, the coal bin is first glued with CA to the Main Frame Boiler Ring, and then followed up with 5-min Epoxy. This proved again to be quite a tricky process as one needs to reach over and up under the upper rim to place the glue on the inside of the joint. Fortunately, the insides of the boiler will never be seen, so neatness is not a requirement!

 

Once the Epoxy had set, it was time to add the upper boiler. Again, the instructions stress the importance of aligning the two boiler walls by aligning the line of rivets at the join in the walls. The Boiler Top Ring is again used as a steadying and forming aid to maintain the shape as the lower edge is fitted into the Main Frame ring. Here you can see the upper boiler in place and aligned with the lower boiler. You can also see in this photo the hole for the Rear Axle Support shaft after re-drilling in the previous step.

 

905039102_93UpperBoiler1.jpeg.7dc04e4d8a5655c7a83ab3e26212947b.jpeg

 

Once again, both top and bottom joints are glued with CA and followed up with 5-min Epoxy. This was even trickier than gluing the lower boiler and the use of long bamboo skewers proved to be an excellent choice of gluing aid. Once set, the instructions ask you to dry fit and then glue in place the Boiler Cap Ring. Once I dry-fitted mine, the fit was so snug that getting it out again to place some glue was proving to be problematic. In the end, I decided that the fit was so snug, that glue wasn’t going to be necessary. Here is the result.

Looks great but there's obviously a bunch of "oh crap" moments involved.  I can't imagine using Britannia metal for nuts and bolts.

Thanks Mark. It's not the nuts and bolts that are Britannia metal (they are brass) - it's the threads on the axles and shafts that are the problematic Britannia metal.

Rear Axle

 Next up is the gathering of parts for assembly of the Rear Axle. This includes the previously painted parts plus some 00-90 nuts and bolts.

 

2023116263_98RearAxleParts.jpeg.7cd557ac0c405f8d9751914bd96e3849.jpeg

 

First up, the Rear Axle is mounted with it’s support shaft inserted through the hole in the lower boiler wall and the Rear Axle Lock (the unpainted disc in the above picture) inserted from inside the boiler and glued in place. Not too difficult, except being able to reach down inside the boiler from above to place the Lock.

 

826356695_99RearAxleinplace.jpeg.a0e4e2f2a398d9ea1f629c4398b979c0.jpeg

 

The next step is fitting the Shock Absorbers and their vertical and horizontal braces, as well as the Coal Bin Braces. While the horizontal braces only have a locating pin to place in the respective hole in the boiler wall, both the vertical braces and the coal bin braces are attached with 00-90 nuts and bolts, with the nuts being secured on the inside of the boiler. While the dexterity required to attach these little critters is quite challenging in itself, the real problem is a matter of alignment.

Even though I had been meticulous in my forming of and placement of the boiler walls, I found that things just wouldn’t align quite properly. I can only conclude that either the boiler walls weren’t pre drilled in the correct place, or the design did not allow for the additional thickness of the boiler walls where they overlap, which in turn reduces the outer diameter of the boiler in order for it to fit within the boiler and main frame rings. Whatever the cause (and I don’t think it’s operator error), the result is that the shock absorbers don’t sit quite vertically, and in order to make the coal bin braces align with the respective holes in the boiler wall, a significant twist is imparted to the coal bin floor. This photo shows the extent of that twist.

The good news is that the model is normally viewed from the side, so the twist isn’t really evident from that angle, and the rear wheels obscure the shock absorbers to the extent that their misalignment becomes largely unnoticeable as well. Nevertheless, it was disappointing to have come this far in the build, only to encounter this issue.

 

Having decided that there was absolutely nothing I could do to correct this issue, I pushed on. Next up was adding the Rear Axle Links and Hooks. These are simply attached with CA glue to the Shock Absorber bracket and Boiler wall.

Front Axle Brace

 The Front Axle Brace now gets attached to the Front Boiler Wall. This is achieved by placing a 1-72 nut on the threaded end of the Brace, either side of the Chain Attachment Bracket and the Brace Plate. The two nuts are then used to adjust the ‘length’ of the brace such that the Attachment Bracket sits flush against the Boiler wall, where it is glued in place with CA glue.

Chains

 Two lengths of Chain were used to limit the travel of front axle and prevent the rim hitting the main frame. The instructions say to cut two lengths of Chain 4 7/8” (98mm) long. Ummmm 98mm is 3 7/8”…. So which is it? As it turns out, neither measurement is correct. I started with the longer length (4 7/8”) and after placing the first one could see that it was way too long. I adjusted it visually so that the chain was doing what it was supposed to do, and then cut it to length – which turned out to be 4 1/8”. The jump rings still need a little touch up of the red paint here.

While I was in that vicinity, I decided to add the Centre Pressure Release Valve as I could not find any further reference to it in the instructions. It took me a while to find it on the drawings too. I could just make it out in some other reference photos later in the instructions, but only as an ‘incidental’ to what the photo was illustrating. As it’s quite a difficult place to get to, I figured installing it now was probably a smart move.

Rear Wheels

 The Rear Wheels are slipped temporarily in place on the Rear Axle. As these will be removed several times yet, I decided to heed the instructions and not try to fit the securing nuts for fear of breaking another axle.

The Rear Axle Guide, Boiler Coal Door and Door Latch were added a little earlier, but I forgot to take a picture at the time. Here they are in place too:

A little diversion now while I attend to the wrappings for the Hose Nozzles and also make up the Boiler Water Level Sight Gauge, before returning to my most dreaded task - installing the Brake System...

Ah... got it.  They probably should have just did a shaft and then used self-tapping nuts.

This is going to be a brilliant model and the 'fake' metal looks really good.

 

OK, with hindsight, but I wonder, whether it would have been possible to 'joggle' the vertical joint in the boiler-lagging. In this way, the outside diameter would have not increased due to the extra thickness of the overlapping material.

 

I had to check the imperial thread sizes, but to me they are not actually that small at 1.2 mm and 1.8 mm diameter. Anyway, it may have been a good idea to re-thread the cast parts with an appropriate die to remove any flash or distortions. In theory, one can also use a very fine triangular file to remove flash and burrs, but it is not so easy to find a fine-enough file for these fine pitches. The problem is that you do some sort of pressure-forming, when screwing the nut on and that requires a lot of force to move the material.

Thanks Wefalck. That’s an interesting point you make about ‘joggling’ the joint - I think I understand what you mean and it makes a lot of sense. It would certainly address the issue of alignment. However, the instructions (including photos) say to do it the way I have. Would be really interesting to try though…. Perhaps the next person to tackle this kit can try that approach - I’d certainly love to see it done that way.

 

I’ve been wondering about the possibility of chasing the threads on the cast parts, but I’m not convinced the metal would stand up to even that amount of torsional force. I’ll dig around in the tool chest this week and see if I have a 00-90 die and if so, might give it a try. What could possibly go wrong? Worst case is I break the thread just the same as if I just try to put the nut on without first chasing it wth the die.

I would suggest drilling the threads out of the nuts, so that they slip on and off the cast threads, then a touch of glue when final assembly takes place. The glue will fill the thread area, and a touch of paint will hide the glue. No one will know that the threads are not there.

It won't Grant, the shafts will snap off.. Been there done that.... The answer is to drill a hole and insert a hard brass rod... I know modelers who didn't even mess with the soft cast axels, the cut them off and go straight to brass or steel rods.. when you screw the nut on it's trying to force form the threads, think for a second, a die will actually be digging in trying to cut the threads, even more torque applied to the axel as the teeth in the die start cutting.....

This is the answer if you don't want to mess with switching the axels to rods.... (it's a solution I've used) and you have hubcaps to cover the glue spot....   You'll want to use epoxy for this gluing as well, CA just won't hold....

Thanks for the input and suggestions Ron and Egilman. Noting Egilman’s comment on thread chasing, I think Ron’s suggestion is the safest way to go. I think then that I won’t mess about. If the nuts don’t go on nice and easily (as they did on one side of the front axle), I’ll drill out the nuts and glue them on. Once they are on, they won’t be under any strain, so a spot of CA should be fine to hold them.

 

Thanks again for the input everyone - one of the many things I love about this forum! 😊

It's our pleasure Grant, the interactions in a forum like this is where the art of modeling grows... it takes the place of the old time model shop where the owner has built everything that was ever molded/sold and knew just how to fix it....

 

I built a coach for a gent who wanted spinable wheels, so superglue was out... in sufficient quantities to hold securely, it freezes everything solid....

 

My solution was to use a brass collar just large enough to fit over the Britannia axel, had to shave one of the axels flash down to get it to slip over....  At time for assembly, using 5 min epoxy, I slip the wheel over the axel, cut a split washer of wax paper a hair smaller than the collar and place it over the collar against the wheel hub, then a dab of 5 minute into the hole in the wheel side of the collar.... (if you get a bit on the mating surface of the collar, that's what the wax paper is for) slip the collar over the axel, and as the epoxy sets up, spin the wheel... The wax paper ensures that little if any epoxy will get on the hub, and the rough surface of the axle ensures a solid joint.... added bonus you can wipe off any epoxy that comes out the collar hole before it cures..... When it's dry it looks just like a greasy hub nut on the end of an axle....

 

Perfect turning wheels that will never come off.... If the coach has exposed hub nuts then drill them out rather than use a collar to keep the hex detail.... When it's dry it looks just like a greasy hub nut on the end of an axle....

Thanks again for all the input (and also for the "likes" following along). A somewhat frustrating day in the workshop today.

What the…?

 Prior to tackling the Brake System, the instructions call for three small jobs to be done: finishing the Hoze Nozzles, constructing the Boiler Water Level Sight Gauge, and making the Brake Spring. All three should be simple, straight forward tasks. All three had issues…

 

Hose Nozzles

The instructions call for wrapping the Hose Nozzles in the rather nice red thread provided using a Common Whipping. We are advised to take a 36” piece of the thread for each Nozzle to do this. I cut the thread in half and noted that each half was very slightly longer than the prescribed 36”. Good, I thought… Then I discovered that no matter how frugal I was in allowing for the ends and the loop, there was no way that a 36” piece of thread was going to cover the entire Hose Nozzle. After some experimentation and a lot of cursing, I managed to make it cover all bar about 3-4mm at the handle end. Why Model Expo couldn’t have made the supplied thread a couple of inches longer is beyond me. It is not something that I can duck out to a local store to replace either. Very annoyed by this totally unnecessary error.

 

Anyway, here is a picture of in progress showing one Nozzle wrapped and the other pre-wrapping.

 

1010302247_108HozeNozzles1.jpeg.479564262c416c657e9cfbd8315c1c2a.jpeg

 

And here they are completed. You can see in the photo where the wrapping stops short of the handles. It should go all the way to the handles per the instructions and included photos.

Boiler Water Level Sight Gauge

The Boiler Water Level Sight Gauge is made of a top and bottom cast part, four connecting brass rods and a clear plastic rod. Here are the parts laid out (and yes, one of the top/bottom parts is facing the wrong way). It’s quite a clever construction design, but …

 

1586176017_110BoilerWaterLevelSightGauge.jpeg.f6ab894fe30a3a73a947273ef379162b.jpeg

 

The issue here is the diameter of the clear plastic rod. The parts list in the written instructions for this component call for a 3/32” diameter rod. The separate drawing sheet for the clear plastic components calls it out as 0.0625” (1/16”). The part that is provided is 1/16”. The recesses in the cast components are sized to accept 3/32” (as confirmed by test fitting a piece of 3/32” brass rod I had on hand). Really guys? What happened to proof reading and quality control? The most frustrating thing about this error is that I don’t have stocks of clear plastic rod to hand. Using the provided 1/16” rod is a non-starter as it will both look wrong and be difficult to actually construct. I have managed to track some down of the right size through one of my ‘go-to’ Hobby Stores, but it is costing me $10 for a pack of 5 rods, each of 250 mm length (I need one piece 25 mm in length), and then it’s costing me another $14 in postage and a wait of about a week or so. Again, totally unnecessary and very frustrating.

Brake Spring

The instructions call for you to make the Brake Spring from the provided wire. A simple enough task – what could possibly go wrong? 

 

Well, first up, the instructions for this appear in two places in the instruction manual – once on pg 25 and again on pg 42. And these instructions are actually different to each other! On pg 25 it calls for using a piece of 28g brass wire and on pg 42 it calls for using 0.020 brass wire. Well, I looked up some tables and 28g is 0.0126”, while 0.020” is 24g. What is provided in the kit is 0.015” which is equates to somewhere between 26g and 27g. It would appear that the instructions were revised at one stage and one version of this section should have been removed but wasn’t. At least they could have provided the right size wire for one set of instructions instead of neither! At least this was an easy fix.

 

The kit provided wire felt a little too thin for the purpose, so I dug through my stash and found some 24g Copper Wire. The advantage of using the Copper Wire is that instead of painting it black, I was able to chemically blacken it with Liver of Sulphur. The technique is dead easy – just insert a 1/16” drill bit in a pin vise with the smooth end sticking our about 3/4” and then wrap the wire around the drill bit. Form a couple of “U” hooks on the end and job done. Here is the result, test fitted between the Seat and the Brake Pedal Arm.

Okay – now I’m ready to tackle the Brake Sysem…
