    Default Making a Wormgear with a Screw Tap (Free Hobbing) A Design & Manufacturing Guide

    I was pondering a few things and contemplating worm gears for minute rotational adjustments, not for power transmission - that's quit a rabbit hole and they are predictably expensive

    Anyway I came across this video for cutting a worm gear of sorts which employs thread cutting taps - just perfect for what I had in mind - really good video also with heaps of information

    The gear cutter in me hates this so much, but it falls squarely in the "good enough for the hobbyist" camp so I guess I can't be too mad about it.

    Hi Guys,

    This was the technique that I used when I cut the adjuster for the angle setting on my version of the Brooks TCG. Pictures in that thread.
