Step drilling goose barrels!

Just the beginning Parker, just the beginning of things you can do with that chuck.

   The wheels are turning Marvin!  Thank you for helping me get lined out on that bit set.  That has helped me out the most.

Sorry I got away from this thread for so long.

 If I was going to use the counterbores, this is how I would do it.

 Buy the 5/8" pilot and a 3/4 and 7/8 cutter.

 Drill the barrel 5/8" all the way through, ream if you do that.

Mount the 7/8" cutter and cut to depth, leaving the hole in the center still @ 5/8

Mount the 3/4" cutter and bore to depth

 Should be a fairly easy gig, and you can find these cutters in reduced shanks if you look around.

 Just do a quick search for pilot counterbores on the internet. Try Victor Machine, that's where I buy alot of my stuff.

Ok, I see your problem.

 Here's another solution:

 look for :

CBTS-7/8

 This is a 7/8" counterbore with a #2MT, just remove your chuck and mount this one to finish.
