David, thanks for your post. I am improving but I`m still not patient enough. I need to learn to sit for longer on one thing if I am eventually to make a Tourbillon, but that is a story for another day.... In retrospect, more time should have been taken burnishing the wheel crossings but to be honest, I`ve only just read a good method of doing it so I suppose I`m just still learning and the next wheel will be better.

Thanks to everyone else for their replies of encouragement.

Spurry/Pete, yes I had to insert each pin into a pin vice and turn the end down on a fine stone. I didn`t include this process in my pin making time! To be honest, it wasn`t really a radius, just as long as there was no sharp points. The beauty of the punch is that it forced the wire inwards to bring it to a nice clean cut tapering slightly in. Using a grinding wheel on a dremel left a very sharp edge and caused a lot of filing to be done. This method only required a quick tidy up of the cut end, I didn`t truely round them.

Hopefully I will find time over the next few nights to make the arbour and the mounting plates.

Hi Chris

Thanks for the additional snippets. Seen and noted. :thumbup:

Made the pin wheel arbour tonight which also doubles up as the drive pully. There is a few issues with this related to the type of line I ultimately use. Basically, the drive wheel obtains it rotation from the falling weight, simply by the friction of the line pulling over the pully. As you can imagine, this is tricky as if the angle is too sharp in the V groove of the drive pully, the line can bind and if too narrow, the line will slip. I chose to follow more advice by John (Gadget Builder) who has suggested to me I try 45 deg as Dr Woodward did and use monofillament line. I can always open up this angle and try builders line if I want to, but couldn`t go the other way unless I remade the pully.

Set about cutting a 45deg V form tool and cutting the pully V:

Collet and arbour complete:

And complete wheel on arbour with a bearing with 1/8" ID stuck on the end just to check they fit :ddb:

Plates next and then get the wheel mounted.
