Hi All,
I have a hopefully "simple" question that I hope one of you may be able to help with ... (BTW I also hope this is the right sub-forum to post in).
As it is I have recently built a lapping machine and now am looking for a suitable "abrasive media" - preferably "DIY" and environmentally friendly.
To this end I have bought some ~400 grit aluminum oxide powder and have learned that I should dissolve this powder in water together with a suitable amount of a "vector / vehicle". I have also heard that some use WD-40 as this vector/vehicle but if possible I would prefer using e.g. a vegetable oil (or e.g. a bicycle oil like Pedro's Chainj, if appropriate) instead. Also, since I will be using the lapping machine in my utility room it is much preferred if the vector/vehicle is odorless ...
The lapping machine includes an "abrasive media" container with stirrer so the abrasives will be continuously mixed.
I will mainly be lapping copper, aluminum and plastic plates (Polyurethane modeling boards).
Might one of you have experience with this - and some suggestions?
Cheers and thanks for any insights
