with a drill you have to worry about being perfectly perpendicular every time, even with a stop. set the plunge stop on your router and forget about it.
I don't want to belabor this or sound like sour grapes either, and if one is sloppy with a drill - or any tool for that matter - the results will be sloppy, but this post got me wondering why I've done so many of these, including hidden pegs that slide in a groove in the shelf edge, using a drill without any problem at all (which is why I suggested it as an option - I certainly would never mean to steer someone in the wrong direction), so I sat down and did the math -
If a person using a drill was out of plumb by even 3 degrees (which takes a litttle bit of doing unless you're just being plain old careless or your jig is made sloppy to begin with - remember, your jig is contributing to staying plumb as well - the stop contributes nothing to staying plumb, only depth) for a peg that protrudes 3/8", they would be off by a total of 2/100's of an inch and that's assuming that all of the error is in one, and only one, direction - I'm not so sure that I could even register my jig placement from set-up to set-up to that kind of accuracy, at least not with MY tired old eyeballs!
If more comfortable or confident with a router, then by ALL MEANS, use it - besides, that's what this forum is all about - and maybe there IS less to worry about with the router. But (and stone me for heresy - my wife will thank you), I do believe a drill is still a viable and simple option for that operation and in fact is probably more talked about and illustrated in plans using adjustable shelves (not that that makes it the best or only option, but it must mean something). At least it's worked for me.
Please, no offense intended Rprice54 - you made me think and practice my trigonometry as well!!
