The drift pin I have found to be the most useful has a tapper starting at 1/4"
tapering up to 5/8" with a steel handle 5" long, one piece. Total length of
12".
Purchased at Sears and as I recall very affordable.

I've ordered Klein bull pins from toolbarn.com. They have a number of sizes
at inexpensive prices with reasonable shipping.
I like to use a tapered pin that is too large to fit completely through the
hole.

I have found Drift Pins in the tool section of Sears. They carry a few
different sizes, a great tool.
