Plane Lapping

What do you use to lap your plane beds? I've been messing around with spray adhesive, wet dry sand paper, and a long piece of melamine as a backer, and I get decent results.

Very similar to you, Teem, I use sandpaper with spray adhesive on a 1/4 inch sheet of plate glass with several grits attached.
Konrad Sauer from Sauer and Steiner practices a VERY accurate and interesting method.
He first uses a marble slab with a paper he found to be the best after trying a bunch of other papers, it's from NORTON intended for the Body-Auto shop industry: Champagne A285
He recently added a STARRET Machinist granite reference surface for the final stages.

Same as Scott
i use a marble slab that was a cut off from a counter top we installed, i also use spray adhesive with norton sandpaper. works great for me.
It all works as long as you have a very flat surface and some good sandpaper. I have used glass and aluminum plate
