Hob for Free Hobbing of Worm Gears

[LMMasterMariner]

Made hob from hexagonal bar of 304 stainless steel diameter 24 mm.
I know it's not tool steel but it will do the job in phosphorous bronze.
First turned one part of the bar to 24.0 mm and then turned to 20.5 mm at 3 spots.
Threaded with TR3 insert and made trapezoidal thread 24mm x TR3.
One part of it will be used as worm and another part is a hob.
Good thing is that this bar is hexagonal, so I could easily place it
in 4 way toll post and turn it for 60 degrees each time for milling.
12 mm cobalt end mill used for milling.
No milling machine, nor rotary table on board.

Very simple job which was completed in 3 hours.

Will use this worm and one of worm gears (30, 32, 36, 40 teeth, still have to make them)
and some of the gears from the last picture in one of my next projects = lathe power cross feed.
