Re: Tapping Heads Tapmatic A5 and ?

You're absolutely right, Harold. Supreme Versatapper by Buck. Looks like I ordered the right collets but might be stymied by the required grease. Mobilux EP 23

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 ...

Re: Tapping Heads Tapmatic A5 and ?

Looks like I'll need J44x and J42x collets.

Re: Tapping Heads Tapmatic A5 and ?

I see how it's supposed to be configured now that I figured out what the knurled collar was for - to release a ball bearing stop. I need another collet and ten of the adapter jaws. I suppose a shop would have 10 of the QC adapter assemblies set up with a variety of taps and then just pop them in as ...

Re: Tapping Heads Tapmatic A5 and ?

Something I'm missing about the tapmatic. It looks like it has the smaller collet, but I see nothing behind that collet for holding the tap square and no screws from the side. This site has instructions with references to back jaw and back jaw screw. It might be that I have the quick change spindle ...

Tapping Heads Tapmatic A5 and ?

This is from a long ago post I made here. I've had these heads and want to know what collets they need and where to get? Also, when I look at the tapmatic site, they list these collets that I think would work: M3 - M12 #6 - 1/2" 22000 4.5–8.0 Extra 22100 3.5–6.5 Standard 22200 6.5–10.0 Standard 2230...

Re: BROWN & SHARPE MAGNICATOR MAGNETIC BASE - STIFF

I wasn't looking forward to taking this apart, so I'm happy to avoid it. Never thought of losing magnetism. I've heard of that with stepper motors too, but not quite sure how/why it happens, unless it is like how a demagnetizer works. I'm sure I've taken apart an import with the turning switch, and ...

BROWN & SHARPE MAGNICATOR MAGNETIC BASE - STIFF

Hey All, I bought just the mag base. This is the one with the push button. The button gets very stiff half way and required two thumbs to press it all the way on or off. Is this normal or worth looking into a fix? It looks like there is a round plug in the back and a couple of brass dowel pins that ...

Re: How would you make this?

You really think there will be enough material? There will only be 50 thou of web at each end. I would have made it longer if I had realized the screw head size. His drawing was way out of scale and it looked like it was fine (he drew it just like it looks in the photos here), until I looked up the ...

Re: How would you make this?

we figured out the design wouldn't work since you have to drill the top open to get the screws in, and that drills out all the material that is supposed to hold the cable in. This to repair a motorcycle engine casting. The casting had a small round bit that would house the clutch cable. The cast mat...

Re: How would you make this?

I don't see the edit button but I wanted to mention, he does not want large through holes on the top. that think is supposed to hold the end of a clutch cable, so the slot is for the cable to slip into.

How would you make this?

0.700 cube
0.350 through bore on one side
8-32 clearance through drill perpendicular to previous bore
0.09 slot through both holes
8-32 flat head countersink, but only on the inside of the bore

Somehow a countersink needs to reach into the middle of the bore, I thin something like this.
