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 ... http://www.manchesterminerals.co.uk/acatalog/Tumble_Media.html#a19_2d007 Maybe other lapidary suppliers have it .. dunno BC |

Thanks BC I have ordered the 600grit carbide from them still looking for 800 grit and possibly 1000grit |

Isnt Diamond lapping paste suitable? :dremel: I'm sure I've seen suppliers of that in various grades available..... |

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: BC |
