Very instructive Eberhard.

Ouch!!!!!

They are temporarily covered with paper to prevent dust from getting inside.

  Thank you for clarifying. I asked because it wasn't unusual to plate over this type of gun emplacement as generally they were of very little use in anything other than calm weather.

Beautiful stern walk Valeriy. Are the aft gun positions plated over?

Keith - i have to agree with the other comments - very nice work.

I made a start on the launch. I don't have the section lines for the hull so i needed to create these. In the following photo I have coloured in the points / lines that I could deduce from various photographs.

I had a fairly good side view from which I could take the keel, waterline, and deck lines. I also had a fairly good picture of the stern and I had a dimension for the maximum beam. From this information i made a guess at the vertical section lines and then plotted the horizontal section lines. I then drew best fit curves to form the horizontal sections and transferred these back on to the vertical sections. I then smoothed the vertical section lines and plotted these back on to the horizontal sections. I iterated around several times until both horizontal and vertical section lines formed smooth curves.

I then cut 1/8" plywood frames and glued on the section drawings. 

I then cut slots in each of the frames to take the keel. All of the frame blanks had been cut accurately to exactly the same size thus facilitating  accurate cutting of the slots on the table saw.

The frames were then cut out using a scroll saw.

A piece of scrap wood  was then slotted to take the frames and the frames were glued in pace with a keel piece maintaining alignment.

Prior to fairing the frame edges were highlighted with a permanent marker.

Balsa blocks were then glued in at the bow and the fairing was done with a sanding block.

The position of the engine was then determined by plotting the line of the prop shaft.

The bulkhead for the transverse seat position was then installed (1 frame rearward of the actual position).

The stern bulkhead on the launch is quite thick so the aft most bulkhead was widened to reflect this.

Finally these additional bulkheads were sanded to match the fairing of the other frames.

Small hulls are much quicker to make than big ones. I must remember this thought.

Wonderfully precise and technically competent clinker planking job Gary. Beats my usual suck it and see approach hands down.

It used to be quite common for launches, especially work boats, to have a fore and aft aligned steering wheel.

Hi John - It must be to confuse potential thief’s.

You really do crack on. Amazing speed and quality as well.

I'd be inclined to keep to the original.

It hurts my head too much 🙃

Most of the engines are of the radial type, but they also have a couple of others:

Eberhard - yes I found them - very nice but I don't think mine will be that complex.

s that yet another launch sitting on the port side under canvas?

TB

Tom - its a RIB - next on the list after the Launch.

Is that wheel a handwheel by any chance?

Druxey - not quite sure what you mean but it is definitely the boats wheel.

Awkward - yes. But it saves a 90 degree turn for the steering cables at least.

Hakan - I think my preference would be to invest in a couple of extra pulleys.

Eberhard - I have not seen the 3 D printed engines - must look them up.

The launch promises to be a build within a build - looking forward to it.

Thank you Gary. I am planning to cheat a little. 

The left hand arrow is pointing at the boats wheel. This is actually aligned fore and aft which I can't really get my head round. I suppose the crew get used to it but to me it is daft (never seen one on a car for instance). I think I am going to have to mount it on the bulkhead just in front of it. 

The right hand arrow is pointing the the seat under which the engine is mounted. Every time I see you guys building engines I get jealous so I am going to move this seat rearward and put an exposed engine in the launch. I know the launch should have a modern Volvo Penta but I think the owner has manage to source a 1920's twin pot petrol engine, that i think is more in keeping.

I hope that going a bit of piste won't get me banned from MSW.

On another note for those who are interested, not shipbuilding, I'm done with the chemo since last Wednesday. Follow up x-rays revealed that the tumor had significantly diminished in size. Next up will be a preop meeting with the surgery dept in 1,5 weeks. 

Still suffering from side effects though, and I'm still very tired. 

But the sun is shining!

Good to hear Hakan, hopefully it is all improvement from here, fingers crossed that you see a rapid return to good health.

I somehow missed the completion. One of the most unusual models i have seen but nevertheless quite charming. Very well done.

As for my tidy workspace, I try to make it a habit of clearing a small area when I take pictures and since they are such large files, I generally crop out some of the picture to get it to a size that will upload to MSW.

 

A picture is worth a thousand words. Cairo looks amazing. Workspace is a 5/10 which is better than my usual score.

Re - I happened by the Admirals craft room where she was hard at work making stencils for T-shirt on her Cricut.

I need one of those. Must get my wife into making stencils for T shirts then I can buy her one for Christmas.

Also I am always amazed that the photographs of your work space and model never have a speck of dust on them. How is this possible?

Beautifully done.

Hakan,

Your off cuts bin looks a bit like mine - wood, broom handles both metal and wood, bit of tubing etc, etc. You have reminded me - i musts sort it out. Nice progress on the build - all looking very neat. 

Thank you for commenting Michael, Richard, Pat, Keith, Druxey and Eberhard. Also thank you to everyone who has visited and liked my work.

around 2000 I was sailing in the British Virgin Islands,

Very nice little restaurant on the east coast of Just Van Dyke i recall. I was there in about 2005 - generally very nice but we found the sailing was a bit constrained by the closeness of the islands.  Great snorkelling at RMS Rhone and at the Baths on Virgin Gorda. On the negative side we found the BVI's a bit over run by noisy catamaran gin guzzler types.

I wonder how it would affect the sailing, as it is probably quite a deck-load.

Eberhard,

Sometimes they sail with it on deck.

And sometimes they don't.

They also seem to spend a deal of time sailing with it replaced by a dinghy.

It must increase the C of G and reduce the metacentric height (while also increasing the starboard list). My guess is they take it with them on position cruises and then land it and rely on the dinghy while racing or cruising within the local area.

I will also be making the RIB which sits on the port side.

The launch is quite big, where is it actually stowed on board?

Eberhard,

Starboard side between the davits installed some time ago.

I continued with the life rings as per the photo.

It isn't very obvious from the photo but the life rings sit in wire baskets. The leather pouch holds the line and this is tied off to the rail.

I started making the basket from .025" wire. I made two formers from scraps of wood and used these to bend the the "hoops" which retain the life ring.

The free ends of the hoops were connected by micro-bore tubing.

I then slotted a piece of plywood to create a soldering jig and I bent the wire which joins the hoops. The hoops and joining wire were then soldered together.

I then tested to life rings in the baskets.

The baskets were then lashed to the guard rails using black cotton.

The pouch is quite small so I cheated and formed it round a piece of scrap wood cut to size. Sail tape (painted brown) to simulate leather was then stuck to the former with 3 lines added to give 6 ends. 4 lines attach the pouch to the guard rails and the other two attach to the life ring and the rail.

I painted the life rings and added the reflective strips and the grab ropes.

The rings were then pushed into the baskets and the life line was tied off.

I think I am going to make a start on the launch next.
