HomeMade Moly...

Postby Preben Hovedskou » Mon Jan 09, 2017 12:01 pm

Due to the (crazy) high prices on Cermark or similar products, most people are looking for usefull alternatives.
Like many others I tryed a bunch of different products containing the magic stuff: molybdenum disulfide, to use as a substitute to "the real product".
Some product works quite okay, others are completely useless. The products is normaly ment for lubricating, why they are based on oil or grease.
It can be quite messy to use, and to clean off again after the marking-job is done.
So I started to think a little backwards and dicided to try making my own Moly-stuff.
We know that it is molybdenum disulfide that make the trick, so first I searched for the stuff in its pure form. On all the big chinese webshops and Ebay as well, you can buy this lovely powder for a quite low price. I bought 250g for arround 13 US$. (just make a search for molybdenum powder)
I then putted a spoonfull pure moly into a cup and slowly added normal dishwashing-soap, until I had a nice paint-ish liquid.
This mixture is very easy to apply with a paintbrush (or maybe an airbrush), and it dryes very nicely into a fine gray substance.
It engraves much better than the different moly-lubricants I have tryed so far. (and I have tryed all the products recommended on this forum)
After engraving / marking it is super-easy to clean..! It's already made of soap, so a quick shower under the kitchen tap will do the trick without any mess. So far I only have done some tests on stainless steel, but they all turned out very well. Later I will test it on alu, glass, copper, brass etc. etc.

So go ahead and try it out... it's cheap, it's easy and it's deliver a good quality.

Happy marking
