Thanks for the link to the books.
Now I understand why your Bug looks so good.
W.R.Smith was a clockmaker. You have a very good influence.
Unlike you, I am not a big fan of filing and sanding. ;-D
I saw that he had a book about Sherline lathes.That is about the size of my micro lathe.
I have a Taig micro lathe which I purchased many decades ago.
My very first drawing used round stock instead of rectangular blocks.
But I couldn't find enough brass round stock, so I switched to blocks.
That first design also had smooth brass rod for spring tension and gap adjustment.
I had planned to use a set screw for adjusting spring tension and contact point gap.
I ended up using 8-32 brass screws instead.
I had to tap the parts for 4-40 and 8-32 brass screws.
I only broke on 4-40 tap, while tapping holes for the finger pads.
Luckily, I was able to extract the broken piece from the hole, and tap it with a second tap.
Right now, my brass paddle is functional.
I doubt that it will ever be 'finished'. ;-D
