--It's a VFD. One of the bright guys in my posse fixed me up with a parts list to do it right and helped me wire it to OSHA specs. Saved a bundle compared to what Royal charges for the same thing.

Why the VFD, as the Royal site says the FMs use a single speed, and
caution you not to cycle them too often. At that price, they should
be more beefy, don't you think? Odd.


That's a big bin of Clecos there. Doing a lot of sheetmetal work?
--Heh a pal gave 'em to me. I wound up parting 'em out to folks who need 'em more than me.

I have half a dozen in the old automotive tool chest from my other
life way back when, 30+ years ago.


I also love the concept of the articulated die-grinder-on-a-stick on
your bench. I was going to ask if you built it yourself but then saw
the warning label. Have you seen the speed controls that come on some
inexpensive die grinders, simple screw with a nut on either side of
the paddle actuator? More of a speed limiter.
--It's a Chinese clone that was within my budget. The American equivalent was $3,000 and I got this one for $500 new on ebay. Did a ton of googling but couldn't find anything like the high speed air drill setup I've got now: these things seem to be specifically made for tapping in production setups, but I had another application in mind. Die grinder came courtesy of a pal who got it from his dad. The curvy shape of the die grinder was too weird to fasten securely in the end clamp so we made a 'bushing' with Shapelock: the plastic that melts in hot water.

Well done! And $2,500 is a hefty savings. That's about how much they
want for a new furnace for my attic. The secondary heat exchanger
delaminated and it's 16 years old, and it threw a couple codes, so the
smart thing is to replace it. But it's a Christmas OUCH.


The beauty of this old die grinder is it uses standard collets. I'm using it to drill 10 holes apiece of an odd diameter in a ****pile of plastic parts for a customer. Still and all I'd like to clone the whole thing so two of us could do the work in half the time!

Amen to that. It doesn't seem too hard to clone. And now that the
pneumatic shocks are available for $15 a pop at Autozone, that's
doable. Pick your pressure!
