Full profile button cutter - video

-That title might be thought of as some sort of a New Year's Quiz, but it's actually pretty explanatory,
IF you've seen (the late) John Stevenson's method of having two spaced, hardened buttons as a quick & dirty form tool
for turning and relieving a DIYed involute gear cutter (of your chosen # of T and its pitch/ Mod and PA).

PS: Personally I don't see myself "wasting time" at Clickspring's site, anytime. But to each his own I guess?
How he uses them:

Anybody who thinks time spent at Clickspring's site is wasted must already be a master machinist. Anyone who isn't a master machinist could profitably spend quite a bit of time there. Among things he shows how to make are hand-cut files, a replica of the Antikythera machine, and square broaches. I suppose if you're only interested in CNC, his site and videos might not be of much use to you. If you have any interest in the history of tools, how things came to be the way they are now making things, or in making interesting and unusual things, he's worth checking out. YMMV, of course.
