I know, stupid question... but I can't figure it out. I was using a right angle, front exhaust IR grinder with a 2" sanding disc to strip a metal shelf of paint.
I usually oil every tool before daily use but I didn't today. I wasn't expecting the grinder to spit out anything, but after 1/2+ hour of sanding it kept seeping out the exhaust and splattering on the workpiece.
At first I thought it was water condensing, but it felt slightly tacky like oil would. On the workpiece, it wouldn't wipe cleanly, also convincing me it was oil. My plumbing may not be ideal, but the drip leg on that drop was bone dry as well. For simplicities sake, I'll leave the plumbing detail for another post.
I tried a 6" DA sander on the same hose - nothing came out of the exhaust - however it has a little sponge baffle that could of stopped any liquid. I think I have a spare grinder somewhere I will have to try. I suppose I could run my IR impact to see if it spits out anything but its a relatively low speed tool so not sure it would have the same affect.
The grinder felt ever so slightly cool. Assuming its water, could it be even though the drip leg was dry, the water condensed after it passed through the high speed grinder? On days I would oil the grinder, it would stop spitting a min or two after use.
