Corey,
I was thinking of getting the set of 3 jigs... 1/4, 3/8, & 1/2 which looks like a pretty good deal (based on your experiences).
Do you think you could have installed the 1/4" jig by merely using a space bar, bit, & jig... marking the holes and drilling them? During your testing, did you have to modify the way the jig was positioned?
I guess that once you setup one jig, all three work with the same mounting holes? If so, really a good deal!! Setup one, get three!

Yes?
Would a straight bit work OK with these jigs (a spiral working better, of course)?
I think you did a great job illustrating your How-to... Thank you for putting it together!
