Re: Tapping Heads Tapmatic A5 and ?

Thanks folks. What a face palm and yet such an excellent learning experience. Aside from the pitted welding, it does look like I'm half way there.

Re: Tapping Heads Tapmatic A5 and ?

Found some time to weld up the stripped threads. Wondering where I went wrong. The 16 tpi nut threads seem OK, but a bit worn. A caliper measurement yielded a minor diameter of ~1.170" max, so the question was what diameter to machine the welds. I decided to machine the major diameter to 1.208", exp...

Involute Cutter Set

Why is this in the junk drawer? Because I suspect too good to be true, even from our friends... #1-8, 16DP, 14.5PA, HSS, sixteen bux. https://www.ebay.com/itm/22mm-Inner-14-5-Bore-HSS-8H-8Pcs-Set-Dp16-PA14-1-2-No1-8-Involute-Gear-Cutters/303511675742?hash=item46aab4a35e:g:dG8AAOSwc7td~F9N Let's hope...

Re: Turning small diameters, right/wrong way

How do you machine away the center, because it seems at that point there would be a lot (all) of the part sticking out?

A little bit of progress. Broke a jaw on my 3-jaw puller. Just an opportunity to make a special jaw.

Re: Tapping Heads Tapmatic A5 and ?

How to fix this thread in the Versatap J440 collet spindle? I am planning to take it off, weld build it with either the MIG or TIG welder, with a mocked aluminum collet clamped into the taper to dissipate heat and hold shape, then single point thread on the lathe. The best solution is probably find ...

Re: Tapping Heads Tapmatic A5 and ?

I've read this general concept about the rubber flex collets in a couple of places, but from my link above: " they are not designed to handle large rotational forces. So most Rubber-Flex chucks employ independent "back-chuck" (square hole, tang slot, setscrews, etc.) to counter tool rotation in the ...
