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??

Have you tried Prussian Blue from an artists' supply store?

I haven't tried it as layout fluid yet, but I use a tiny dab of nail varnish on nuts and bolts to serve as a visual indicator of loosening.
Cheap nail polish either neat or thinned out with a suitable solvent should adhere well, is non toxic and can be removed easily with acetone, You can get it in lots of different colours too.

Prussian blue dries very slowly and is best used as an indicator when scraping a surface. I've used ordinary gloss paint for this, it does the job but is very messy.

Hi,
What I have found works well is a mixture of old ballpoint pen ink mixed with methylated spirits with a few flakes of shellac added.
Make the recipe to suit how light or dark you need by varying the constituents.
Store in a sealed bottle with a small paint brush jammed in the lid.
Good luck.
