Curious to know if there are any plans to build one in the wild. The cheapest one I can find new that looks to be worth a damn is the Royal Filtermist and it clocks in around $1,300, which is waaay over my budget.

--Bit the bullet and bought a Royal Filtermist. I saved a bundle by making my own stand for it. I also did a tiny bit of sheet metal work and made a 6" to 4" duct reducer. Photos start about halfway down this page: https://www.flickr.com/photos/steamb...57675365635032

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.
--It's a VFD. One of the guys in my gang (Sebastopol Makers) is an EE who builds test equipment where he works and he's been very helpful.

Nice!


That's a big bin of Clecos there. Doing a lot of sheetmetal work?
--A pal dumped 'em off; one of those 'here Ed you need these' things. Since
then I've managed to disperse them to the vultures.
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.
--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.

Slick, dude.
