It's an actual lapping bar sold originally to hone woodworking tools.
Got mine from Lee Valley Tools:

I lube it with diesel rather than water... works a treat and the price is pretty reasonable.
The only downside is that it's pretty soft... I find I need to true it fairly often. Lee Valley also sells the tool to keep it true !
Actually, if you want to go that fine,
www.rockler.com sells "Micro Mesh"
ranging from about 2400 grit up to
12,000 grit for $3.59 per 3"X6" sheet.

Crikey 12000 grit, what the heck is that like? A mirror?
A CCD out of a small camera has bigger dots :lol:
