Well, we took it to 1000 today and decided to stop for the day.
Will pick it back up tomorrow and go on up to 2500.
Trying a variety of common options.
Straight Windex, diluted Windex, plain ole tap water, Simple Green mixed with water.
Tap Magic cutting fluid, Mobil 1 (5W-30), Red Line (5W-30), WD40, 3-in-1 oil, lightweight mineral oil.
I suspect the "best" agent is gonna depend on the desired finish and the abrasive involved. As usual, what you're trying to achieve in conjunction with what you have available to use.
We're using cheap SiC wet/dry for the whole process because this is a learning process for my daughter, and I want her to learn the value of quality abrasives.
So far, the fastest results with the paper we're using, even up to 1000 grit, have been with plain ole water. No surprise to me based on previous experience.
Tomorrow we'll go 1200, 1500, 2000, 2500.
Based on previous experience, I suspect once we get to 1500 and above, the various oil products will really start to come into their own, and I'll be more able to note differences and form an opinion.
One thing is for sure- this gives me every opportunity to be very objective in forming an opinion on what provides the quickest way to get to the end goal.
Cora is already eyeballing both the belt grinder and buffing machine, asking when she's gonna be big enough to use them instead.:58:
