This is the combo driver I made for the screwdriver swap. I experimented with a triangular handle as I hoped it would provide a better grip. The handle was turned from a triangular blank. I first made a rectangular segmented blank of walnut and maple., and then cut it . I then cut this into a triangular block. I sanded the sides smooth using one of the cut of sections to maintain the correct angle of the sides. From the end, the blank is an equilateral triangle with 60 degree angles and equal sides. I then turned this on the lathe to round off the corners.

I had to review some trigonometry that I had not used for years to determine how long the sides of the triangle needed to be. I decided the diameter the handle needed to be at the top of the ratchet mechanism. I then calculated the length of the side by multiplying that by .866 (sine of 60 degrees).

-- Ride the bevel!

This is COOL! Now I want to figure out something to make just to try turning a triangle. Maybe file handles? Not sure. I will put it on the long list of ‘roundtuit’ projects

I experimented with triangle handles early on in the swap. I just couldn’t pull it off. You got it just right though. Excellent job!
