Lap, lap, lap your seats, under the diesel spring...

[duffer]

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:
