Hob for Free Hobbing of Worm Gears

[LMMasterMariner]

Hello old_toolmaker,

I did it from hex stock because I had it on hand and didn't have milling machine on that vessel. Left it there after fabricating several worm gears from phosphorous bronze. Already had too much steel (weight) in my suitcases, so I didn't take it with me. Have gear cutters at home for making gears in metric modules 1 and 1.5. Also have rotary table and milling machine to do that. If I need to make another hob again will do it from better steel and will not do it with trapezoidal (acme) threads as they are too shallow for worm gears.

Best regards
