Running this one by the folks here. I am getting ready to start casting my Gingery Milling Machine parts. Hopefully will have something to show soon.
Anyway, not wanting to spend half a paycheck (so it seems) on some professional marking fluid, I have decided to TRY making some.
Lo and behold I had a pack of black RIT dye lying around, as well as some denatured alcohol.
Mixed those two together and I do believe I have made some very inexpensive marking fluid. It seems to have worked well on the different surfaces I have tried it on.
I have to admit the stuff is a bloody nightmare on skin. Also not sure on cleanup, though I know denatured does work.
I have used regular 'magic markers' before, but I tend to go through a lot of those it seems (sure, leave a cap off for a few....)
Anyone else have experience with marking dyes and such they'd like to share??
