Master Airscrew Balsa Stripper is one of the best tool I've been using....

1) What I do is to set the depth about 1/32" - 1/16" below the surface and also the width to 3/4"

2) Since my workbench surface is particle wood (Too much drag on the Balsa Stripper) - I put down two pieces of balsa wood under the stock. (leaving space between the cutting line for ease in cutting)

DONT FORGET TO USE THE EDGE THAT YOU JUST MADE TRUE!!!!!
