Frank and Calvin, I just noticed Frank said that he is going to "try the Windex again"
If you don't mind me asking, for what purpose are you guys using Windex?
My 1st guess would be the "water cuts" part of the equation, but it's just a guess.
Yes, well I try to keep learning and not refuse suggestions I ask for. A few people say windex does a good job at least to start. I keep a small spray bottle in the shop to clean my glasses with. I do have a cutting fluid called Jokisch which is like an oil and have used it. It's pretty good stuff but expensive.Frank
This was is a great tip that was shared with us. Thanks again! I was recently sanding a blade for a friend and found another great fluid to use, CLP (cleaning lubricating protectant, we use this on all of our fire arms in the military). It's not as economical as Mobil 1, but it is what I had handy at the time (I seem to have alot of little bittles of this stuff lying around fir some reason).
I bought a quart of Mobile 1 10w30, a bottle of Simple Green and some Rynowet from Supergrit today. I got 120, 280, 400 and 600. I figure if the Simple Green doesn't work, I can use it to clean the Mobile 1 off of the blade.:3:
Im not going for a mirror finish so I thought 600 should get a decent satin finish.
I just bought 10 sheets of each grit, hopefully this will last for a few blades.
I'm assuming you apply several drops or more to the blade prior to the beginning of sanding and then try to keep a decent amount on it by adding as it naturally runs around to the bottom of the blade. Correct Calvin?
There's definitely a difference between cutting and polishing. Last night I finished cleaning up my mil-build knives (pre-HT) with 220 and plain water. I can't swear to it but it does seem to cut a little faster that way. Then I switched back to Mobil1 and 400 grit, and I still like the way it polishes. I'll continue to try different "lubes" at different grits and see how they work.
In the meantime, I've been using plain unscented food-grade mineral oil to protect carbon blades from rust for a couple years now. It doesn't stink, won't make you sick and doesn't eat up leather. I never thought to try it as a sanding helper!
