Back lapping

Enter a word or two to search the forum section and click the Search Forum button.

I'm about to try and back my first ever mower. It's a 14" cylinder, any advice on how much and what grade lapping compounds am I likely to need? Any general advice/guidance would be welcomed.

The first question has to be; Why are you backlapping your cutting unit ? Are you doing this to sharpen the cylinder and bottom blade, or to keep the the already sharp edges ? If the former then stop now, you cannot sharpen a cutting cylinder by backlapping, you can only maintain sharp edges.

As for the rest, do a search on this forum, this topic has been raised several times.
