Looking For Sanding Belt/grit Recommendations

[shammatt]

I recently purchased an Acme 2C Horizontal Edge Sander. It runs a 2" to 3" x 60" belt. I'm sanding 18" long pieces of stitched two layers of 12oz. leather. My need is to quickly dress up each side of the layers to match. I also add a small radius to each corner. I have a power burnishing tool for further finishing, plus my edge coating. My question is two-fold: Any recommendation as to the grit of the sanding media (80?) and what type of sanding media (aluminum oxide, other?). Thanks!

I have a regular ole tablet belt sander. On it use 50 grit to get things where i want them then use a 180 grit, edge and then burnish. i use the aluminum oxide belts.
