Hello,
I want to buy some lapping film (1,3,5,9u) but it's quite difficult to find in Europe.
I have find 2 stores in Europe that have this films, both in UK:
Cousins have 3 and 9 microns
Worshopheaven have 1 and 5, but these are PSA.
Do you know where can i buy all those grits from a single place?
And another question: how is PSA working ? I mean if i stick it to a piece of glass, can i get it off and reaply it latter ?
I'm not sure about the UK, but over here I find it at all the Fibre-optics suppliers.
That industry has traditionally used fine lapping film a lot for polishing fibre-connectors.
I think i asked all the Fibre-optics suppliers in my contry (Romania) and nothing. Only one of them have such films on stoc, but they sell minimum 50 pieces of each grit...
Hardware store that caters for painters and stores that sell stuff for repairing damaged paint of car bodies.
I did my best trying to find these films but i had no luck...Quote:

For razor honing, I don't really think you need so many different grits. 9u-micron is around 2k grit. 1 micron is somewhere near 15k. The rule I generally follow is, the next stone in the honing process should have around 3 to 4 times smaller particles from the last. 10 micron to 3-4micron and then 1 micron.
You can email those sites, they might have some pieces, if you haven't already. Both of them offer pretty cheap shipping and lapping films are not 2kg whetstones.
A different option would be sandpaper. They are the same thing. 1000, 3000, 5000 grit sandpapers, and then, you can go to 1 micron lapping film. It works pretty well and its cheaper.
Quite an old thread but I have bought from here all grits for £12 with postage -
