The lapping film I found is 0.05 micron not 0.5
Question for those who use the .3 um; does it tend to give an edge that is too sharp? Im thinking of trying this, but wondering if i should go for the 1 um or the.3. What grit would the 1 um be comparable to?
I wonder if a Delrin kitchen cutting board is flat enough?
Don't buy lapping paper. Buy lapping film. Lapping film.
Film is NOT paper. It is acetate. If it says "paper" maybe they are mistaken and it is actually film. If they don't know their own product, I don't think they are a good vendor. If it IS paper, then you don't want it. I agree, buying PSA film is not a good idea. The adhesive thickness variation and compressibility are additional wild cards, and wetted plain back film will stick just fine, to a nice smooth surface. But as for removing the adhesive residue, acetone works very well. I also use it for removing spray adhesive from my plates, after bevel setting with sandpaper.
I should have read more of the thread before I ordered, I got the Zona kit off Amazon and there it is on page 114 that it doesn't work. It's not a wasted purchase as I can still use it, it's a very good cloth, but the curious mind want's to know why they won't work, but the acetate ones do? I tried and tried to set a bevel, even went to the 30 micron, but nothing, like I'd not even touched it. May just have to order the sample pack with the PSA on it and just deal with the cleanup of the sticky residue.Well heck! Looks like I ordered the wrong pack... has a 'woven' back. Guess I should focus on getting my Arkansas stones burnished in then, but still looking for a finisher.
