Thanks Highpower.
I picked up a couple of chinese 150mm diamond lapping discs off ebay a couple of weeks back (only about $4 each delivered). Have 600#, 1500# and 3000# ones to play with.
Also managed to get a cheap $20 import grinder to run them on, just needs some backing plates made up. That was on my list for this weekend but the bits I grabbed from the scrap parts at work for stock turned out to be some sort of very hard material - a file doesn't even look at making a mark on them. I could possibly turn them with carbide tools on the lathe but have nothing to make a hole in the center so will get some more suitable material.
I'm planning a diamond cup wheel for the other end of the grinder.
I like your wood base and support - nice quick way of getting something working, and one can always remake it later if required (although usually they work well enough that it never happens!!).
