sourcing 600 & 800 grit carborundum in the UK
pipemakermike:
I have reached the "lapping the cylinder" part of my engine building project and I am having trouble finding a supplier of the finer grades of carborundum for lapping the cylinder and piston. I have got 400grit but need finer.
Any ideas would be helpful

Hi Mike
Manchester Minerals have 600 in Silicon Carbide ... no carborundum though ...

Thanks BC I have ordered the 600grit carbide from them
still looking for 800 grit and possibly 1000grit
John Rudd:
Isnt Diamond lapping paste suitable? :dremel:
I'm sure I've seen suppliers of that in various grades available.....

The Cerium Oxide is like talc. I have used it on a brass cylinder, but it's very slow .
Why not use toothpaste or Basso if you want that sort of finish.
Not that I've done many cylinders, but I don't bother too much about getting a polished bore.
I have a hone, just used that and left the cross-hatching marks in.
The piston will finish it off when it's run. :lol:
