I just use the countersink center drills like I center drill the joints with. I usually use the #2 size.

I'd suggest you support your local outlets. Look for machine shop supply / industrial supply places in the yellow pages. In my little city of 200,000 people there are perhaps a dozen places where I can buy center drills. Of these all but one keep industrial hours (M-F 8-5, no evenings no weekends).

Please don't think that I am against mail order purchases, but for these kinds of $5 - $10 items it is good to know where you can get them locally, imo.

Step 1: Drill a "starting hole" with a solid carbide CNC 60 degree spotting drill
Step 2: Drill with a center drill

You don't often see people post the correct procedure of starting with a spotting drill. I don't get too hung up on the rep thing, but I reckon that is worth one...

Spotting Drill

Thank you Kelly. For the benefit of those you do not know; before drilling any hole with a lathe a spotting drill should be the first thing you reach for. A "center drill' is not designed to be a hole starter.
