I was inspired by Terry Werm's No Fog Coolant Mister plans. http://www.hobby-machinist.com/showthread.php/19957-No-Fog-Coolant-Mister?p=169932#post169932, but don't have the funds at this time to purchase the parts needed for the build.
I remembered that I had an old FRL which works on a similar principle as the NFCM along with some other old valves fittings and air lines, so I dug through my tubs of stuff and cobbled this together. I did have to spend about $20 on pipe fittings that I didn't have on hand. The black flex line which blows on the cutter is from a broken BBQ grill light that I had. I will probably end up replacing this with an actual flex able air nozzle/line. The air lubricator is adjustable, so I can control the amount of oil or coolant I'm putting on the cutter. When I tested it today it worked pretty well.
I had added a flow control that I had on hand, but found that I did not need it. The small shutoff valve at the manifold mounted on the quill stop works fine for controlling the flow of air & oil.
While putting my coolant mister together. I though I would try to come up with a way to catch at least some of the chips and put together a vacuum tube on a bracket mounted to my vise. It does catch some of the chips, but a lot seemed to bounce off the back wall of the tube. I think I will try adding a thin piece of rubber sheeting to the back wall of the vacuum tube to absorb the impact of the chip allowing it to fall into the air stream going to the shop vac instead of bouncing back out.
