  1. Thanks a lot, Moab and Michael. You've reinforced the value of build logs to preserve the spirit of this forum. They help the builder as well as others. Even if I don't finish it, it's the steps along the way that are meaningful. After all, without those there would be no model! Tony
  2. That looks pretty effective. On mine I had to put a wedge between the drill holder and the support on which it revolves because it was very slightly out of the vertical. Is yours ok in that regard? I've enjoyed modifying mine as well. You can see all my mods to make it a mill in my build logs if you're interested.I Tony
  3. There's also the Taig/Peatol lathes. I have a second hand one and it works really well. In the US the micro-lathe (the one I have)with some tools starts new at about $450, without tools for $380. There's a great deal of information on how to use them on the web. A particular advantage is the way the tailstock can handle drilling by moving the chuck with a lever. I bought mine for £300 from eBay with a large number of tools and cutters, which I thought very good value. Their mills are good too. I use mine both for wood and brass. You can see the Taig lathes at http://www.taigtools.com/ and the microlathe II at http://www.taigtools.com/mlathe.html. Tony
  4. How nice to see these builds continue, Gregor. As usual, beautiful work. What process and materials did you use for the stove, wheel and pumps? Tony
  5. A quick search on Google for 'wrap to a surface in turbocad' shows answers that seem to agree with Pat's suggestion that this can only be done with the Platinum version. e.g. https://forums.turbocad.com/index.php?topic=18161.0 It's very expensive (£1000) to upgrade if were to do it from my ordinary version of Turbocad 21! Tony
  6. I don't know if this helps, but during my build of the Sherbourne I had a query about Petersson's illustration of the mast tackles, or what he referred to as the Burton pendants. As you say, he has three pairs of shrouds on each side which should make for 6 deadeyes if that was his intention and if you look carefully at the illustration with the mast tackles there is one block for the tackles on the port side near the mast head but without the remaining tackle, whilst the tackle on the starboard side is shown ending on a belaying pin and a ring. I found his illustrations confusing because as you note he has varying numbers of shrouds as well as being confusing about the tackles. I don't think the number of shrouds matters as Steel in his section on the rigging of cutters says "SHROUDS, four or five pairs, are fitted and got over the mast-head, similar to those in ships. The after shroud on each side is wormed, parcelled and served with spun-yarn, down to the deadeye." In relation to the mast tackles, I followed Marquardt's illustration as you can see in the discussion at: You can also see how I approached it in my build log at https://modelshipworld.com/index.php?/topic/335-hmc-sherbourne-1763-by-tkay11-finished-–-caldercraft-–-scale-164-a-novice’s-caldercraft-sherbourne/&page=8 Tony
  7. Thanks, Dirk. I was just about to comment on your great build of the Maria -- the pictures of which just came up in my MSW digest. As usual I am in awe of your skills. And I'm delighted that you can still spend time to keep a friendly eye on my builds! Tony
  8. Thanks, Nils, for the kind words. I'm not sure it's a tutorial, though. More just a detailed explanation of what I have chosen to do so that others can assess when building their own models or comment if they feel there are better ways. I'll admit, though, to that little gasp of pleasure people experience when they take the hull off the mould and see it all stick together as a skeleton. Skeletons have their own attraction. Now to see if I can breathe some life into it! Tony
  9. Great words everyone! Especially 'fun'. Michael: definitely for the builders sharing our early experience, but always looking for guidance from the more experienced! Thanks! And now on with the build to bring it up to date. Finishing the mould The final, but important aspect of finishing the mould was to cover it with wax or silicon to prevent frames being stuck to it when gluing floors and futtocks. I used the belt and braces approach by first spraying the whole mould with a silicon spray and then covering it with car wax. This gave me no problems when removing the shell from the mould. The only word of warning is that some modellers, having put a wax on the mould, found that, when they were heating frames to help bend them whilst on the mould, the wax would fix the frames to the mould. I didn’t experience that either as all my heating was done before putting on the frames and wales. However I did find that on several of the frames there was a residue of wax which was hard to remove except with a knife – so there may be a problem when I come to gluing the internal planks to the frames. In future I’ll just stick to the silicone spray. Calculating the amount of wood needed To calculate the amount of wood I made up a spreadsheet (based on measurement from the plans) which was sorted by plank thickness for clarity in ordering. You will note that I ordered 2x2mm sticks for the frames. This was because at the time I hadn’t given thought to the question of the floor size and assumed I’d be ok with the advice from the guide to use 2x2. I don’t yet know how accurate this spreadsheet will prove to be, but I can say immediately that I had also not thought about the question of spiling in relation to the planking which would mean thinking of strips 11 or 12mm wide. This is an issue (along with the issue of the floor size) that I will return to later in the log. Item thickness width length number total length gunwales 1 4.4 380 2 760 internal planks bow 1 4.6 54 16 864 transom planks 1 5 80 6 480 cubbies 1 5 20 8 160 cubbies 1 5 90 8 720 External planks 1 6 380 26 9880 Rear decking 1 6 75 11 825 floor planks 1 7 230 11 2530 washboards 1.5 3 350 2 700 internal stringers 1.5 4.6 320 2 640 planks behind swivels 1.5 5 30 4 120 taffrail 1.5 7 85 1 85 frames 2 2 250 30 7500 footrests 2 4 100 9 900 rubbing strakes 2 7 380 2 760 thwarts 2 7 100 9 900 transom 2 8.7 82 1 82 rear bench seats 2 10 50 4 200 cannon rails 3 7 180 2 360 rudder 3 7 70 1 70 rudder 3 7 40 1 40 bench rests 3 9 230 2 460 side knees 3 9 36 10 360 anchor davits 3 18 22 2 44 cannon rails 4 4 180 2 360 swivel supports 5 5 24 4 96 hoisting beams 5.35 5.35 85 2 170 I had chosen pear wood for the model, and some of this I had left over from the Triton cross-section build. The rest I ordered from Arkowood in Germany. It is difficult to get pre-cut sheets of pear of varying thicknesses in the UK because the good pear wood here is taken mostly for making veneer and the lengths of pear wood left are of variable quality. It certainly is convenient to have much of the wood pre-cut. Arkowood are able to supply strips of up to 100mm wide by 1000mm long with thicknesses that range from 0.5mm to 10mm. They also are cheaper in shipping (€16.50 to the UK) than the other big wood supplier (Massiv-Holz) which charges €26 minimum. Stem, Stern and Keel I did not take pictures of how I made the stem, stern and keel, but just need to remark that I made the lap joint between stem and keel by a straightforward milling out of the recess between both pieces and some very careful filing. I made the rabbet before adding the apron to the stem, although the guide suggested cutting the rabbet afterwards. This I did in three stages. I first used the mill to form most of the 1mm rabbet from where the rabbet joins the keel from the stern to the base of the stem. This is shown in the following picture, which also shows the further adaptations I made to my proxxon drill for use as a milling machine. You'll see all the mods in my Sherbourne build and other posts. I then cut the rabbet into the knee of the stern with a 1mm chisel I made from an ExActo chisel blade. You can see this and some other miniature chisels I made from an old hexagonal key (3mm) and some HSS lathe bits (2mm and 1.5mm). The handles are from an old broom handle, turned on a lathe. Finally, I made a scraper from a hacksaw blade to cut the rabbet that runs between the stem and the apron. I also used this scraper to tidy up the rabbet I had cut with the mill. If I was to do this again, I’d just do it with the scraper template. Keelson There is not much to remark about cutting the keelson. I had to remember: (1) the upward curve towards the stern, (2) to mark the positions of the mast step and the thwart supports. I used a combination of Plans 3 and 4 to establish the markings (I drilled 0.5mm holes right through so they can be seen from the top), and milled out the 0.8mm deep grooves for the floors. Frames I then started work on the floors. On the French forum there was much discussion about the fact that the plans indicate that the floors are 3mm in thickness whilst the booklet suggests making the floors and frames from 2mm square sticks. Most people seem to build the model with 2mm square sticks without much of a problem (or so it seems) but I couldn’t see how the frames would be faired with the last four frames and the first three frames which have to be made from plywood cuts derived from the original plans. For those such as myself who are anxious about this, the suggestion was to add filler blocks, but I decided it would be easier to make the floors from 2x3mm stock following the dimensions implicit in the Plans. The 2x3 stock clearly had to be shaped so that it narrows from 3mm at the middle to a 2mm thickness at the ends in order to merge with the 2mm futtocks. To mark the ends of the floors I used 1mm feeler gauges clamped together in a vice and a micro saw as follows. This method had an added advantage that I could use the 0.05mm strips planed off to make micro-adjustments to the height of the floors later on. Once this was done, I could bend them to shape using a jig. The next question was how to construct the first three and the last four floors. Because these would be difficult to make from 2mm strips, the guide suggests they be constructed from 2mm plywood sheet. M.Delacroix wisely suggests that 7-ply aircraft plywood be used. Since these would be invisible in the completed model, it will not matter in terms of appearance. In ignorance I bought 2mm ply thinking that was the same thing. It isn’t. It was 3-ply and crumbled quite a bit when I made the floors. The rear four floors were at least manageable in terms of providing a base for the planking. The first three floors were quite a different proposition. I tried making them from the ply I had bought and even from some pear stock, but all my efforts failed. The problem was cutting the first three floors to the rake of the stem on both inner and outer surfaces. This leaves a thin base to the floors which is very easily snapped. I eventually was able to buy 7-ply aircraft plywood, and this did the trick. You will see from two illustrations below some of the difficulties with the first two floors and futtocks. The plans show that the futtocks also cut into the apron, but although I cut out the grooves for them my attempts failed at cutting and bending into these grooves the 2mm square pieces for the futtocks. They all broke. In fact I have not seen any models that have done this, but I thought in the interests of learning I’d have a go. Instead I filled the spaces I had created for the futtocks with Milliput super-fine white epoxy putty (which is great as a filler, especially when it can’t be seen in the completed model) and ended the futtocks away from the apron – as is shown on the photos in the guide and on the other models I have seen. The other thing to note is that the guide suggests using a bevel to align the floors with the apron and the stem. I found that the only way of doing it was through a bit of trial and error, mostly error and breaking 3 floors to end up with one. I used a riffler file to align the uppermost surface with the apron. Another way to do this might be with a rounded bit on a rotary tool. To illustrate what I mean, the following shows frame 7F, the foremost frame, with the outline that covers both floor and futtocks. Ideally I would draw the frame from both its forward and rear sides (the plans don’t have any frame outlines as you have to devise them yourself), but the illustration should be sufficient to give you the idea. It took a lot of thinking on my own part to interpret the plans, so I hope that this explanation will shorten the thinking time for others who may find the same difficulties. The transom I positioned the 2mm ply base for the transom. It was cut deliberately oversize around the base to allow for adjustment when fairing the frames. This was done before adding the futtocks. I then glued the floors to the keelson, and the keel assembly to the floors. Then pinned the ply base for the transom to the mould. Bending the futtocks After reading Chuck’s posts on planking and his proposition that dry heat is sufficient, initially I tried just using dry heat for the frames with a hair dryer, bending the sticks over copper plumbing pipe and over a soldering iron. I found this impossible. No matter how slowly I bent the sticks, they all broke. So I went to heat with steam. I made three jigs. (1) for the frames between 7.5R and 5F, all of which were based on Frame 0; (2) for the frames from 5.5F and 6; (3) for the frames 6F to 7F. The one for Frame 0 is shown in the following photo: I then soaked lengths of 2x2 pear wood in boiling water for 20 minutes and bent them using a soldering iron along the sides and edges of the wood. I covered not just the immediate area to be bent, but also further along the wood on either side to ensure even distant wood fibres would stretch. I held the iron to the wood until steam could be heard sizzling from the wood. I then held the iron along the side in the same way, moving it back and forth until the sizzling started. I only moved the frame gently until resistance was felt, then I applied water again with a brush and repeated the whole process until the frame was the correct shape. I then moved the iron along its complete length until fully dry. Frame assembly I glued the keel assembly to the floors on the mould with epoxy and ensured it was vertical by pinning stern and stem with two pins. I then added futtocks 7.5R to the stern deadwood, and pinned them into place with 0.5mm styrene rod. Then I made the knights or bollard timbers and glued them to the sides of the apron, and then locked the foremost frame with styrene dowel as well. The extra intermediate front frame was then added and fixed with the styrene rod as well. I completed the assembly round the stem by filling all the spaces with the epoxy putty to ensure the strength of the area and a good base for the external planks. The following picture was taken after I had installed the wales. Wing Transom The wing transom was cut from 2mm stock and a rebate of 1mm milled to accommodate the top plank of the transom. I remembered to drill the holes for the future installation of the rings and the upper gudgeon for the rudder. You’ll see a white blob on the last frame in the picture above. Just as with the foremost timbers the joint at that position was not strong, despite the pin I had put in. So I surrounded it with epoxy putty just to make it really secure in readiness for the sanding. Wales You’ll already have seen the wales in the preceding photos. I cut these using from 7x3mm stock which I cut down to width with a table saw and the correct thickness with a Proxxon thicknesser. I then used a scraper made from a hacksaw blade to give them their shape before bending to the hull. I marked out the position of the wales on the frames, placed transparent tape over the marks, copied the marks to the tape, then transferred the tape to a plywood board. I made small stops for the holding pins in order to avoid marks on the wales as they were bent. I then bent the wales to shape very simply in two stages by spraying with water and heating with a hair dryer: (1) in the vertical direction; (2) in the horizontal direction after they had dried. Although there was some spring back in the vertical direction, when it came to gluing the wales to the futtocks they went into position without a fuss. As before, I used slow-acting epoxy (Araldite regular) for fitting the wales as this gave me all the time necessary. Finishing the rabbet I finished the rabbet by cutting it below the transom and bevelling it to align with the floor directions using a small burr on my drill. Taking the hull from the mould After sanding the exterior of the frames, I then took the hull off the mould and sanded the interior. I found I had over-sanded the last four floors on the port side, so used the epoxy putty to make them good. They won’t be seen in the finished model, so no great harm done. So this brings me up to date and future logs will be shorter. Next up will be the external planking, so it may be a while before the next post! Tony
  10. Glad that life now allows you to continue! Nice work! Tony
  11. Thanks, Druxey, but self harsh? Not really. I see it as objective assessment and as a stimulus to further improvement. It's not false modesty either. I just want to be clear to others what my objectives are at my stage of the game -- the good things they might expect as well as what not to expect. When I look at my performance I give myself good marks for thinking, learning, explaining, risking and experimenting, but low marks for finishing to give the beauty that others achieve. I especially enjoy finding ways to fix the mistakes that I make -- even though the fixes are then quite visible. That doesn't mean I don't appreciate the work, just that it's in comparison. I know that as I continue I'll get better at the finishing. As with my response to Chris, I do appreciate all the encouragement and advice that you and others give so generously. I'm certainly going for it, as always!
  12. Ha ha, Chris! Just you wait to see! All the same, thanks for the hopeful encouragement! At the very least I do much enjoy the whole process, and that's the main thing. Tony
  13. That's funny, Ron, because last night I had exactly the same thought! I think that's the way to go. I've just started my build log, by the way. Tony
  14. INTRODUCTION AND OTHER BUILDS In June 2017 I was considering what to build next. The main criterion was to keep learning but with a different type of boat and a different type of construction. I tinkered with the idea of La Jacinthe, Le Rochefort, and even thought of embarking on Ed Tosti’s plans for the Naiad. However I thought a logical next step would be to go for a longboat using a mould as construction type. So I started on Gérard Delacroix’ plans for the French armed longboat of 1834. The plans for this are available in several languages from Ancre at https://ancre.fr/en/monograph/31-monographie-de-la-chaloupe-armee-en-guerre-1834.html. As stated in the English translation of the introductory manual, the model is “based on a draught in the 1834 Atlas du Génie Maritime (Folio of the Corps of Naval Engineers). The longboat, at 42’8” long, is of imposing dimensions, being large even for a ship’s boat: a man standing on the bottom boards would have the thwarts at chest height.” This type of boat was used for the transport of the heavier loads required by warships and diverse tasks including carrying of anchors, shore duties, watering parties and carrying stores when the ship was in service. They could also participate in harbour defence and sometimes were armed with a single gun as well as several small cannon. There are several excellent builds that can be seen on the internet. The place to start, of course, is with the forum devoted to this model on Marine & Modélisme d’Arsenal at http://5500.forumactif.org/f83-la-chaloupe-armee-en-guerre-1834-plans-gerard-delacroix. There you can find a general discussion about points of interest that people come across while building the model as well as several builds. Very few of the builds go into the details of how they overcome problems as they come across them. However one in particular has gone to great lengths to detail each step of the construction. This is the build by Jean-Jacques Herault, which you can find starting with an index to the build at http://modelisme-arsenal.hlt34.fr/journal_de_la_chaloupe_armee_007.htm. All these builds are in French only. For builds in English, though, there are several on this forum: · Jeronimo’s build at https://modelshipworld.com/index.php?/topic/497-chaloupe-arm%C3%A9e-en-guerre-by-jeronimo-1834/#comment-5561. (Just pictures, no discussion of techniques). · Aykut Anşin’s at https://modelshipworld.com/index.php?/topic/5550-chaloupe-armee-by-aykut-an%C5%9Fin-small/#comment-159523. Only shown as far as the mould, last post in Feb 2015. · Decoyman’s (Rob) at https://modelshipworld.com/index.php?/topic/4218-chaloupe-armee-en-guerre-by-decoyman-from-the-delacroix-plans/#comment-120001. Fairly full discussion but last post was in July 2015, and only as far as frames made on the mould. · Smac’s gallery of the completed build at https://modelshipworld.com/index.php?/gallery/album/109-chaloupe-armee-en-guerre-1834/. · Blockplane’s (Chris) at https://modelshipworld.com/index.php?/topic/14743-1834-42ft-longboat-armed-for-war-by-blockplane-scale-136-first-time-wooden-boat-build/&. Complete, last post in May 2017. There is in addition a very useful series of 11 videos of a complete build (called Chalupa Armada) by Nacho Gomez starting at https://www.youtube.com/watch?v=HlUJabWYFTY. Each of these is over an hour long and is a useful reminder of how to use basic hand tools. All are spoken in Spanish, but even if you don’t speak Spanish the videos are almost self-explanatory. No doubt there are excellent builds as well in the Russian, Polish, East European and Japanese forums, but as I don’t speak any of those languages I simply have not researched them. If anyone does know of such other builds I’d be grateful to add them to the list. MY AIMS WITH THIS BUILD LOG Clearly, with so many builds of such high quality, you’re not going to get anything classy in this build log. It is a very basic build by a novice with poor finishing and lots of mistakes and ugliness. However, as with my previous builds, these are presented as they came, with the idea that there are lots of other builders with the same lack of expertise who come across similar problems and would like to see how I might have coped with them. I also know that along the way those who are more experienced might well chip in and give words of caution, advice and rebuke. All are welcome! FIRST STEPS As usual, the first steps are to study the plans and trace them into a CAD programme so that I can make accurate copies for cutting out and for planning. I use TurboCAD, which is very low cost and which I am now used to. The next thing is to make the mould. The plans are based on making a mould from 5mm thick plywood sheets (the waterlines are space at 4.5mm). Since that size is impossible to find in the UK, I had to work out how to make it from 5.5mm sheets. That meant making the waterlines spaced at 5.5mm, and so I set about doing just that using the time-honoured method of calculating the points of each waterline from the body plans of the station lines and the station lines set at right angles. In order to do so, however, although you only need the body plan from Plan 2 for the mould to create the water lines, I thought it would be a good idea to draw the frames completely as I’d have to be doing that anyway. The way to do this is to combine the body plans from Plan 1 (which shows the station lines to the edge of the frames but without planks) with those from Plan 2 (which shows just the body plan for the mould itself, without frames or planks). The result can be seen in the following diagram of one of the frames, Frame 4F (F for Front or 4Av in the plans, for 4 Avant). This shows that the frame starts at 3mm at the keel and taper upwards to 2.2mm at its tops – but this is an issue to which I will return later when I try to correlate the suggestions in the book to use 2mm square stock for the floors and futtocks against the 3mm floors derived from the Plan. For the moment all that matters is the trace of the inner aspect of the frame to create the mould. The following is the creation of the new waterlines to space at 5.5mm, which is the thickness of the plywood I was able to buy here in the UK. You will also note the various measurements I also inserted to help with the placing of the wales and the stern timbers. With the drawing of both the waterlines and the frames completed, I could then move on to drawing the outlines of each of the waterlines for the 5.5mm plywood. The method follows the classical way of doing this, so no surprises here. A final question that I faced for the creation of the mould was how to do that from Plan 2 because the stern shown in the drawing on that Plan has a very troubling empty space. At the time I decided to just follow the sweep of the hull, but it later dawned on me that a more exact way would be to superimpose the tracing of the outline from Plan 1 onto Plan 2. That way both the line of the hull and the cut for the sternpost and deadwood would be clarified. Should I ever have to rebuild the mould I’ll be doing it that way in future. The following diagram should explain it better. Now that all the drawings were ready, I set to cutting the waterlines from the plywood and, for the keel, cutting the 1.6mm groove for the keel using a 3mm milling bit on my Proxxon drill. I’ll be showing how I made the modifications for using the drill as a mill later on in this build log. I cut the outline for the sheer view with a scroll saw and a sander on my drill. The individual stations were printed to thick card and the cards then glued to a 2mm plywood frame for strength. And at last we get to the assembly of the waterlines. The above picture was taken on the 27th July 2017, just before sanding. After sanding it down I had to put aside all modelling as we were packing up the house to prepare it for sale and spending time searching for a smaller place to move into. I’ll therefore leave this log for the moment and the next part will take it from 29th September this year when I finally was able to start work on the model again. Tony
  15. Thanks very much, Bob. A very logical analysis. Good point about the butt blocks. I attach the illustration from May's book which is for a 23' longboat of 1758 and shows the shift of butts. It states that this was the size that became established for larger frigates in 1769. Interestingly, even though it's only 23' long the planks shown are in the region of 12' long (according to my measurements of the scanned page, but also pretty obviously just from eye-balling). Tony
