    Default Sealing atoma lapping plate?

    I came across a couple of references to sealing Atoma diamond plates (to prevent rust?). Is this recommended?

    I sealed my first one, by recommendation, and it still rusted a bit on the sides. I did not seal the others I got later and they are just fine.

    I thought the plate was made from aluminium?

    The base is aluminium. The diamonds are bonded to a thin steel plate which is secured to the base by 3 strips of double sided tape.

    I haven't sealed any of my diamond plates, Atoma or DMT ......... the rust gives them character ...........

    I'd rather not have to muck about with sealing it, but was just wondering what was best longterm.

    This thread is the first I've heard of it. Truth be told a couple of my DMTs (got 4 of them) have rust on the corner going up into the diamonds a wee bit. Annoyed me when I first noticed it, but I haven't done anything about it, and it doesn't seem to be getting worse after a couple of years.

    Originally, there was a chance that if enough rust builds between plate & abrasive strip it may bow & not be flat. It's really hard to guess how long it would take & even if it is an issue for one's local humidity levels but if Tsuboman has not changed the build its really easy to spend a few minutes & caulk up the sides. I have one atm that is not sealed . Let you know in a few years if it warps

    What do you use on the sides?

    I've used any number of glues & sealents. Just need something that will adhere to smooth aluminium. 5 min epoxy is always a safe bet if a bit messy. Building glues in a small tube are good if waterproof & require no mixing & have a nozzle for application.
