Hello Pawel She continues to look great, nice little plane. -
The dolls house plan may not work. She has one I built for my daughter 30 years ago. However you may be on to something. She is a jigsaw fan so maybe that can be a first project for the scroll saw.

I thought I should update even though I am banned from the workshop until the decoration of the lounge and dining room is finished. Optimistically this is scheduled for a week today. In the meantime I took time out to order an Excalibur 21 inch throat scroll saw. I need a plan for broaching this with my wife before the delivery van arrives. Oh hum!

Binnacle 2nd attempt:- The body was made as previously explained. This time I reversed the direction in the chuck and cut the circular plinth as part of the main body. Previously the plinth had been made separately and this introduced the weakness that led to the chip. The conical cover was made from bar and the first operation was milling the flat and then drilling the hole for mounting the viewing tube / window. The conical form was then machined on the lathe. Likewise the viewing tube was turned up from bar and the two parts were glued together with CA. The cover was then glued to the stem again with CA. The bottom square plinth was cut from mahogany and drilled with a central mounting hole and 4 peripheral holes to take the brass balls. The balls were made using "Michaels stanchion method".

Hello Bob The frames look excellent. Very neat given the scale at which you are working.

Hi Michael. Many years ago I spent part of my apprenticeship in the Rolls Royce Ltd draughting training school and I remember the line dividing method from there. It was however in the dark ages before CAD and has faded in my memory. Your prompt is well made.

Bedford - you may be right. At the moment I'm still in block avoidance mode - so as a distraction I made the compass binnacle. This may be a bit of a long post and depending on the call for dinner it is likely to be a tail of two halves. Altairs binnacle has a stem of mahogany which has detail of longitudinal panels. This sits on a plinth with brass ball details at each corner. Atop the stem sits a removable conical cover with a viewing tube set at an angle. The whole thing is about an inch in height with a stem diameter of 0.3 inch. Turning the stem was straightforward but I wanted to machine axial slots to represent the panel detail. To get the spacing on the lathe required a bit of improvisation with a sheet of paper. The paper was wrapped around the chuck to get the circumference and then folded in half 3 times to give 45 deg increments. This was then used to mark increments on the chuck. The engineers square was held on the headstock with magnets to create the reference. The axial slots were "planed" by traversing the saddle. Unfortunately I ended up with a very small chip in the base, just visible on the right - so this one was thrown away.

Michael the walls are mahogany from the old table I have been recycling. The top and base are from antique block floor tiles which I although they have a paler pink tinge I think are still mahogany.

Julie The shaping of the assembly only took about 10 minutes. Sanding the individual block took about the same time once it was parted off. Thanks to everyone who hit the like button.

John Thank you. I think I am going to have to intersperse block making with other tasks, I can't face up to the prospect of banging them all out one after the other. Much too tedious. I haven't counted up how many I need lest it drives me to despair. I will save the count for when I am in a good mood.

Pawel They all look very good. Keith -
Today I spent much of the time cutting 3" x 2" x 8 foot lengths of timber to repair the lounge floor. As a reward I finished a 2 pulley block. In terms of size it was a case of the ridiculous to the sublime!!!!! The pin is a standard 20mm dressmakers pin.

Pawel What are the barrels made from, they look like metal but the white one suggests something else? -
Cleats and Pulley Blocks:- On the inside of the bulwarks are cleats for attaching the fenders. 5 per side. They are fairly simple with a single central mount. I decided to have a go at making the pulley blocks. I have not made wooden pulley blocks before and decided it was worth having a try. The fall back position is buying them. Altair has single double and triple pulleys and I decided that 2 or possibly 3 sizes would cover the range needed. I started by sketching out the designs. I decided to start with the middle sized pulley block 0.2 x 0.3 inch. I need a number so decided to build them as a single unit which would allow 1,2 and 3 pulley versions to be parted off as required. I started by slotting mahogany and then cutting strips to the width of the finished pulley. I made a mistake on one of the slots - adding up becomes more difficult with age!!!!! I also cut the square block from which the walls of the pulleys would be formed. I drilled the square block to take the pulley spindle. This was a step too far as the drill was much too flexible and wandered off. Next time I will drill the spindle hole once the pulley has been formed and separated off. The wall section were slit off from the drilled block, and assembly commenced using PVA glue. Once the assembly was complete shaping commenced. I made a concave sanding block to assist control of the shaping operation. The assembly is now sanded to shape and awaiting further operations.

Michael - re drilling the holes in the stanchions. I find that getting the drill on the centre line can be a challenge. The best way I have found to do it is to lock one axis of the mill and cut a slot in hard wood using a single pass of a cutter a coupe of thou smaller in diameter than the part to be drilled. I then press the part into the slot and drill without changing the locked setting. This works pretty well and if I want to have repeatability on the lengthways dimensions I put a nail in the slot to act as an end stop. How did you cope with centring the hole in the stanchions?

Nice bricks Pawel. What are they made from? -
Thank you all for your kind comments and likes Following John's (Jim Lad) suggestion I mounted a sheave at the head of the bowsprit. I then finish off the other detail using bits of brass wire, tube and turned bar. I also made and fitted the reinforcing plates at the top of the hawsepipes. The mahogany for the bowsprit is light in colour and my best effort in correcting this involved 2 coats of Georgian Mahogany stain followed by 2 coats of Walnut. Not quite dark enough yet though!!!!

Pawel Thank you - Very nice - but i don't have CNC so I will have to find another way of making them. -
My time has been much diverted so progress has been slow. I decided to make the bowsprit but only had square section timber available. I have a 4 jaw independent chuck but changing over from the 3 jaw chuck is very tedious and I wanted to find a quick solution to holding square section stock for masts and spars. The primary requirement was to hold and drive the square section stock while turning the diameter at the opposite end. I made a wooden hub with concentric bore diameters. The concentric diameters being made in a single operation using a step drill. The square section of the timber goes into the nearest across corners diameter hole. A piece of sting provides the drive and the tape takes up any slack in the fit. I installed the hawsepipes. The upper ends were filed to the correct length and angle using wooden guides temporally held in place by double sided tape. I mounted the bowsprit foot on the deck. The bolts holding the foot down are reading glasses repair screws - from ebay.

Pawel A bit of information on how you made the blocks would be quite helpful. I have a number to make. Thank you. -
Thanks John. That seems to be the most sensible solution and has the benefit that it will look right. I'll go with it.
