After multiple requests, I am now making truncated cone saw bolts and nuts. They are available in two sizes.
The large variant is intended to replace those found on several Disston models from the mid 19th century. Their overall geometry is very similar to the originals, but as these are made on a lathe (not cast like the originals), there are some differences.
The small variant is a scaled down version of the large, and is intended for use on smaller backsaws or anywhere a lower profile is desired.
Full details and specifications are available on the order page. Depending on the response, there may be a delay of a week or two in getting orders out.

Edited to add: The truncated cone nuts and bolts will be available as on option on all of my backsaws going forward. It will take me a few days to update the website; until then, they can be requested in a note at checkout.
How do you make the slots in the screws? I am wanting to widen the slots in some of my old Stanley lever caps screws to fit my Lie-Nielsen chipbreaker screwdriver (.070″ wide).
Brian,
I do them on my lathe with a slotting saw. If you decide to widen yours, you could probably do it with a warding file. If you have a lot to do, it may just be easier to buy another screwdriver and thin the tip a bit.
