Is that a contactor or VFD in the box on the back? They sure don't
give those Filtermists away. Wow. Very nice work, Ed.

That's a big bin of Clecos there. Doing a lot of sheetmetal work?

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.

Very nice sheet metal work!!

--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.

--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.

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. 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!

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.

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

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.

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!

--Ah. That's something special I cobbled together for a production job. I bought a production tapping setup on ebay (wanted to buy American but this one cost 1/6 as much!). I removed the really beautiful pneumatic tapping unit and replaced it with an old die grinder that used the same collets I already had for a toolholder on my mill. With the die grinder's speed and the collet's range I can now drill holes at the correct speed. I've made an aluminum guide plate with a dozen drill bushings pressed in. The over arm assembly makes alignment a breeze and I've got time per hole down to 5 seconds.
