As Grant said above Mark, a brave decision to scrap v1 and start over but it was a good one. It's looking grand!

mañana, lijado t empezar a hacer pequeñas tallas

Thanks everyone for the comments and Likes.
Its been a long couple of days working on the gearboxes, yes I ended up redoing the casing a couple of times over, I also opted to redo the inner stuff as well. Although the micro gears worked they were not as smooth as I wanted. I ended up using some 48DP "pinion wire" it is actually 10 tooth brass pinion, and is exactly 1/4 inch in diameter. this way I was able to go by the numbers and make the proper distances for the gears to mesh'

In order for the gearbox to be able to lock so that the prop rotates forward there is a clutch that is splined, I have been wracking my brains working at finding a way to make a small spline. This morning as I woke up it hit me.
 

 
Yup the trusty old allen head cap screw has a negative hex to accept the hex key, I matched up a 5/16 cap screw with some 1/4 inch hex brass. the steel collar will revolve in the base of the forward/reverse lever and will move about 1/64 to clamp the prop shaft to the gearbox causing the forward motion. the hex part will be pinned to the prop shaft, and a loose clamping collar will be inserted between the hex collar and the casing of the gearbox, when the lever is pulled back the hex collar will move forward clamping the case and loose collar hence locking the case to the prop-shaft
 

 

 
The revers is accomplished by clamping the gearbox inside a steel band which was made from some steel rings turned up and silver soldered together. As the gearbox is clamped the splined collar also releases the loose clamping collar allowing the gears inside to impart the reverse
 

 
The rings were machined to shape using the mill and the lathe.
 

 

 

 
When I cut the slot on the top of the band it automatically sprung to a smaller diameter which works in my favour because in order to open the band a wedge has to slide forward, this wedge is connected to the forward reverse lever.
 
It is getting there.

Thanks for the likes .
 
I did make the casing today and fitted the gears inside.
 
the gear for the prop through the end that will be shaped with the cone recess.
 

 
The casing with the pinions and the drive gear which will be pinned to the crankshaft.
 

 
The cone end with the pinions dropped in and the gears lined up for the casing to slip over.
 

 
All dry assembled I also spotted three holes for some 0x80 bolts to ensure the casing and cone stay together and do not move relative to each other.
 

 

 
I did check the reverse by rotating the prop to see that it actually worked to this stage. still a long way to go to get it all mounted and working in situ.
 
It did work though so I am pleased about that.

Crowsfeet
 
The Crowsfeet prevent the topsails from chafing the lower stays, and also stop them from getting snagged in the tops.
 
I used Gutermann Quilting Cotton for these. It's not quite the same color as Chuck's running rigging line, but it is the closest match they make. This stuff is made from cotton and has a polyester coating which makes it a little more rigid than normal cotton - this makes threading it through tiny holes a lot easier. It also has NO fuzzies at all .
 
The line starts on the strop at the top of the euphroe and passes over the forward edge of the top and through the middle hole. Then it comes back up through the adjacent hole on the port side, down to the uppermost hole in the euphroe and through the top on the starboard side. These steps are repeated for the remainder. The last line is tied off to it's adjacent partner underneath the top.
 
It was a difficult job to get even tension on all the loops of line. I had to go back over all the loops a few times to get an acceptable result :

I have the plans for Altair up in my workshop cupboard - not sure if it'll ever get started let alone finished.  

The block on top was added after a month or so of using the sander as by then I was sick of the dust that it blew out. The hole is just the right size to fit the vac hose. With the vacuum attached all the dust is taken away, I don't even need to wear a dust mask while it is operating. The round cap is used to block the hole and also to check the condition of the sandpaper during use without removing the front cover.  Here are a couple of extra pictures showing some of the details.

Part 97 – Planksheer / Main Rail
 
In the first picture the a portion of the port outer planksheer rail is being fitted.
 

  The height gauge is being used here to check the height along the rail before inserting pins to hold the correct line.  This part of the rail needs to be beveled to fit against the flare of the bow.  In the next picture the rail is being glued with the pins holding the line.
 

 
I spent a lot of time checking heights this week.  In the next picture the height of the lower edge of the main rail is being marked out to set the top of the band of planking between the rails.
 

 
The distance between the height of the planksheer and the main rail varies over the length of the hull.  This became apparent when setting these points.  It seemed wrong, but the drawings verified this.  This made me suspect my drawings but the original table of offsets confirmed the variation.  The planking of this band between the two rails is further complicated by the flare out at the bow.   This makes the true projection of the band wider than shown on the vertical section.  These differences are small, but critical if the planking is going to converge at the top of the frames.  I was doing a lot of height checking this week.
 
A part of the inside of the main rail and fillers between frames have been installed in the next picture.
 

 
The “look” of the inside of the bulwarks is starting to emerge.  An outside view of this work at the bow is shown in the next picture.
 

 
The bottom of the inside of the main rail must match the height of the top of the outer band of planking.  The next picture shows why.
 

 
In this picture the outer main rail is being fitted. Its top is flush with the tops of the filling pieces between frames.  All these rails are horizontal.  The last picture shows the inside of the bow at this stage before fitting the main rail in this area.  I say "fitting" because the outer main rail will not be installed until later - for painting reasons.
 

 
The next step is to install the thin planking above the main rail up to the tops of the frames leaving a tight space for the outer main rail.  This will be installed after the surrounding planking and the rail itself are painted - black and white respectively.  It is also time to fit the rails and planking around the elliptical stern.  Can’t wait.
 
Time for a holiday break.  Happy Thanksgiving everyone – well at least everyone in America.  My British friends used to tell me they celebrated thanksgiving on July 4th.
 
Cheers,

Hello guys !! After a long absence from  my build due to workload , I finally manage to finish it.
Thank you for your support. I will post some photos to the gallery.

Thanks everyone for stopping by and for all the likes, it is very motivating.
 
I have been out of the shop since Thursday evening I went to Calgary to visit my grandsons and play "electric trains"
 
Today I did a little more work on the water jacket, I finished shaping the insert for the bottom of the jacket sweated it in place and bored the holes for the sleeves.
 
Also did some shaping of the top part of the cylinders. after making a second milling cutter for the curves on the top.
 

 

 

 

 

 

 
The stainless sleeves are reamed and fitted, they are a press fit.

Part 94 – Main Deck Framing 5
 
Because the main deck framing supports the mast partners, knees are installed as reinforcements at the partners.  I also installed them at the hatchway openings.  I made these as overlapping knees.  I did not go to this trouble for the lodging knees at the side because their fore and aft arms are not visible on the model.  I do not yet know if these central knees will be covered with decking or not.  The first picture shows some of these knees before installing.
 

 
The next picture shows a few installed at the main mast partners and at the hatch just aft of this.
 

 
I installed these central knees first before going on to the major task of setting all of the ten dozen or so lodging knees at the sides.   The next picture shows this lodging knee installation proceeding aft from the bow.
 

 
The next picture shows a closer view of this work. 
 
 

 
This is one type of lodging knee combination used on these ships and is the one I used on all of the decks.  It is the simplest – with the fore and aft arms simply butting.  They will be covered by the waterways in any case.  In the picture a knee is being marked so it can be cut to fit neatly between its partner and the beam.  Bolts are then installed, the knee is polished up and then glued in.
 
The next picture shows all of the main deck lodging knees installed.
 

 
And, finally, a picture of the full hull at this stage.
 

 
The next step will be to install the ledges between each of the beams to complete the framing of this deck.

Thank you all for the likes.
Brian, Jack, Mark  thanks for the kind comments.
Ed the more I think about laminating the ribbands the more I like the idea.
 
I discovered that at this small scale there is little room for error. When I removed the support plugs today after finishing the shaping and a few more holes for the water inlet and inspection hole in the front side, I saw that the port holes had in fact penetrated the wall of the water jacket. the space inside the jacket is large enough that I decided to add a plate that will get sweated in place.
 
the first picture shows the two crescent shaped holes from the port drill breaking through the wall.
 

 
The sleeve insert is machined from some  hard 3/4 brass rod the wall thickness was .020"  I sliced off two rings then cut those further to just fit enough that the curve is slightly greater than half the diameter inside. By doing it this way they are snug enough that they do not fall out.
 

 
The next picture shows the inspection hole which still need cleaning up and the cylinder liner positioned to show the water circulation cavity. I will make the base plate before the liners are finalized. It has occurred to me that I will need a pretty good filter system to keep any debris out of the water system.
 

 
The next photo shows the top of the cylinder with the head removed the holes still need to be reamed 13/32 for the stainless liners. I am still contemplating making these two parts able to be separated I think I have enough space to add some small long bolts up through the water jacked that way they would be hidden.
 

 

 
I think I need a break from metalwork and do a little whittling of the boxwood stem and sternpost.

Part 92 – Main Deck Framing 3
 
Framing of the main deck continues from forward and aft.  Additional operational features are also being installed.  In the first picture the topsail sheet bits  and two round openings for the anchor chain chutes  are installed.  The samson post is being glued in place toward the bow.
 

 
This very large timber extends up above the forecastle deck.  It will support the lever arms for the anchor chain winch located on the main deck just below the forecastle break.  The levers were operated from the forecastle.
 
Working just one step behind the drafting sometimes causes problems.  The next picture shows the step for the main capstan, which I neglected to install when framing the middle deck.
 

 
The decking between the two hatches and the middle bay of framing had to be removed and reworked to include support carlings and the square step itself.
 
The next picture shows the extent of the main deck framing at that time – a few days ago.
 

 
The next picture is a different view.  The three rows of carling under the deck cabin can be clearly seen in this picture.  The cabin will extend some distance further aft than the beams installed here.
 
 

 
The next picture shows some additional progress on the aft part of the main deck.
 

 
The members that will support the capstan on the main deck have been installed including two large support carlings.  The design of these supports and the step is speculative.  It will soon be time to make the smaller forward water tank and install both iron tanks while there is still access.  The bilge suction pipes will also need to be installed soon.
 
The next picture was taken while I could still place a smaller camera on the middle deck.  The view is forward along the middle deck
 

 
In the foreground is the main hatch and the bilge pipe openings.  The dark areas along the waterways are shadows of the deck beams. 
 
The last picture is one of those scary close-ups taken through one of the view ports.
 

 
This was taken at F8 – the smallest aperture on the smaller camera - so the foreground is out of focus, but the detail of the knees on the middle deck framing can be clearly seen – also a scarph jint in the deck clamp.

After a lot of googling and researching I have bought a UBEC that can deliver 6 volts and 8 amps with a peak of 15 amps. The device is designed for LiPo batteries which are quite a bit lighter than the NiMH battery I had and the connectors are new and different so I decided to bite the bullet and go LiPo.
 
I bought a bunch of the new connectors too and re-fitted the whole system, they are gold plated and should make better contact than the old ones but the wires have to be soldered on which in my case is no problem as I am an old hand with a soldering iron.
 
She is starting to get a bit busy below decks now.
 

 
This is the UBEC
 

 
The new battery jammed in to the port bow area
 

 

 
I know we have all seen her with sails raised before but this is the first time they have ALL been raised by the radio and it is running very smoothly with no dramas thanks to the new UBEC and when I plug the ESC (speed controller) back in its supply will add to the available power so I am feeling pretty confident that my electronic problems are behind me.
 

Update, at last.
 
As stated before the pipe work below deck is a pain but I have now completed all of it to the aft deck house.
That includes raising and lowering the sails, tops'ls and controlling the sails.
 
Next step is to raise, lower and control the stays'ls, this will be done from the fore deck house.
 
Here is a little clip.
 

I have been slack lately, not looking forward to the lazy jacks.
 
I have sorted them now and I can now lower the sails properly. The video is a little bit dodgey as the camera kept trying to auto focus but it's ok. Once all the running rigging for the tops'ls is done I think it will be smoother and more controlled too.
 

She's beautiful Ilhan, very crisp and clean. Congratulations on finishing a perfect model.
 
I hope you are covering her, to keep the dust off. 

We have reached a truly momentous occasion...........

I am so pleased with how the sails raise, it takes a fair bit of effort but the servo handles the task with ease.
I can't lower them properly yet because I have yet to run the lazy jacks to the servo, when they are connected the gaffs will pull down easily and the bulk of the sail will be controlled rather than spilling out all over the deck.

More plumbing done, I am getting better at bending the pipes without needing to cut and adjust, the joint in this run is to make the distance, the pipes are only 30cm long.
 

 

 

She looks fantastic in the water Michael, where she is meant to be. 
 
Looks like a launch and recovery trailer is necessary unless you build a dock and RC crane down at the lake.     

Thank you one and all for your thoughts and input regarding the colour.
 
I will add the white waterline when the red and Black are hard.
