Very interesting Mike,

Nice simple jig for a change compared to many on the web.

I like those pilot drills too, Bruce, and I have a couple of stub drills in larger sizes which I use in thin gauge steel. Being short, unlike jobbers drills, they don't get the wobbles and create that wonder of engineering science, "The triangular hole".

Don't walk into your local hardware store and ask for them though unless you want a blank stare back from the kid serving you. They are readily available however at good industrial supply businesses. Shown are an 11/32" and a 7/16" stub drill. Both are made by Sutton, an Australian and N.Z. company. Not Chinese gold coloured either.

Cheers,
