GEMMA 1863 - hyw-1:36


Recommended Posts

I think it would be very interesting for the tool-junkies among us to have a presentation of your workshop - see the thread 'Where do you do your's then ... ".

 

Do you do a sping-cleaning every time you take pictures ? I don't see any saw-dust whatsover

😯

 

Very crisp work on the patent spill and the pump indeed. Just to pick a bit at it (apologies): it shouldn't actully be spur wheels with straight teeth (see image below), but rather a 'ratched' wheels ...

I think that hyw - unfortunately he didn`t tell us his name - built the winch strictly according to the drawing released by ANCRE.

So there`s got to be a different way to lock the gears to prevent the winch from spinning reverse.

A gear that`s shaped like a circular saw blade with a pawl, that engages at the steep side of rhe teeth, is self-locking indeed.

But I think that self-locking of the winch on this particular ship is obtained in a different way.

Moving the long two-sided lever seems to spin the winch. Perhaps friction prevents it from spinning reverse.

E.g. you turn a rotary table by turning it`s worm gear. But you can`t turn the worm gear by turning the table.

It`s self-locking without a pawl to be engaged.

Marvellous work on Gemma.

Michael, all the wheels are ratched wheels in fact. There are a couple of pawls inside the levers that are made from two hollow castings and that are retained by a groove turned on each face of the wheels. There is somewhere a drawing of this Armstrong patent windlass on the Web. The GEMMA drawings don't seem to be quite correct in this respect.

Thank you for pointing that out. I did misinterpret. When this piece is finished, I will post a separate post showing the tools I created and designed. Keeping the work environment clean is a good habit, and the chip in the process also has a great impact on accuracy, so I use two high-performance vacuum cleaner to clean garbage.

Marvellous work on Gemma.

Although I made the locking mechanism according to the drawings, I did misinterpret the shape of the gears.

If this is an advertisement for awesome clamps and tools, count me in! I want them al!!

We are what we repeatedly do. Excellence, therefore is a habit, not an act.

I could carry, paddle, walk and sing with any man I ever saw. I have been twenty-four years a canoe man, and forty-one years in service; no portage was ever too long for me, fifty songs could I sing. I have saved the lives of ten voyageurs, have had twelve wives and six running dogs. I spent all of my money in pleasure. Were I young again, I would spend my life the same way over. There is no life so happy as a voyageur's life!

Stunning work!  Did you make those thimbles, clew hooks etc yourself?  If you did, could you please show us how you did it?

 

cheers

Thank you for your attention. Since I have to focus on my model project, these tools are just a hobby, and processing them takes up a lot of my time, so I'm sorry not to sell them.

Thank you for your attention. Many of the unpublished tools in this image were created by me. I mainly use the lathe processing, milling processing way production. I also like to make any part of my model in these ways; after this piece is finished, I'll post another post about my various diy tools. Have a nice life!

I think we all would love to see photos of the processes, the stages of fabrication, and not only the brilliant products ...

I'm sorry I didn't live up to your expectations. Almost all of my work, especially when I'm working on a machine, I never take pictures that aren't relevant, just to be safe and to make sure there are no mistakes.

Thanks for the explanation; they are among the best fittings I have seen made - you truly have a remarkable talent.

Thank you for your comments. I came to this world-class Forum through the introduction of friends, very like the atmosphere and environment here, hope to learn a lot of master works can improve their level, do my best to do each work.
