I just push the screws into the pad with a little lube on the head and screwdriver shank. For a thick pad I use two screwdrivers and never completely remove them or screws again until finishing. I do not use a jig. Tried one and didn't care for it.

Unfinished stock, I mount pad on stock, apply couple layers of tape and get it close on a belt sander, finish sand by hand to flush.

If stock is finished I put one layer of scotch tape and cover that with two layers of masking tape. I then get it very close and remove a layer of tape. Then get it closer with sand paper and block. Remove last layer of masking and very carefully hand sand to scotch tape. Never had any complaints.
