If you have a room full of mist you are not running it right. > Yeah, the first time I applied air pressure it emptied the reservoir of Vactra #2, in about a second flat, but nowhere near all of it went on the mill. Most of it went out the gap between the hose barb on the bottom, which was rigged as an automatic drain valve. So it got pulled out, washed up in acetone, blown dry, and sealed in place with some super-glue. Then the little 'needle' valve turned out not to be a needle at all, plus it ran out of threads before it was turned off, so I had to force it, and now its backed off from a full stop by maybe 2 degrees. Then I filled the reservoir with another 1.5 oz of Vactra #2 and made two spockets. That worked well except for the backlash in my table. I could see the bit pushing it one way climbing to the top of the tooth, then slip back a degree or so as it headed down the far side of the tooth. The root of the tooth is too wide and it won't roll into and back out of the chain without a bad catch on the tooth being pulled out. The tables worm has been pushed over, and its now running 999999 degrees each way till whenever trying to wear in the bull gears high spots.

Great idea Ron, consider this done, sometime tomorrow. I assume I should anneal first? This brass seems to be very well work hardened right now. >ron ginger -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
