I have had occasion to see the value in one of these but, never forked out the money for one (or a dozen as they are a wear part). I have a long list of "stuff I'm gonna do when I get that chest of drawers outta here" and this one just rose to the top. Made from scrap hardwood. The initial setup takes 10 or 15 minutes; making the rest of them takes about 5 minutes more . Since the figgerin' and setup time is the bulk of the work on things like this I always say "go ahead and make a bunch". I made 6 each with 1/4", 3/16" and 1/8" over hang as opposed to making it adjustable. I figure those sizes will handle about anything I need.
