Saw this video on youtube and had to try it.

Used HF hex bits with point ends ground off and quick bit holder, knelling pad and velcro from HD. Used a hole saw to cut both wood and pad.Velcro could also be gotten from Vince). The best part was the quick attachment chuck for the discs. I found that without having to change disc the velcro seems to hold up better.S-disc-2.JPG
