I can't mic its diameter there. I can maybe find some at my local TSC|NAPA|ADVANCE AUTO, but I'd need to refresh my memory on the bolts body diameter, and take a 6" caliper with me when next I go there. Since I also need some 6 and 8 inch, 1/2" bolts to mount the barrel vise, its a matter of remembering to do that before I go. Up till now, it hasn't been a high priority. Now that I recall, the Ackley reamer was tapped 1/4-28, so a std 7/16" 12 point socket was used. And I haven't checked to see if the center socket in this reamer is tapped, greatly simplicating its use insitu.
I'd got back to bed after putting on a pot of caffeine, & Dee just now rang the intercom to see if it was ready, and its 11:24am local, so I'd better mobilize me. Being retired plays hell with ones schedule... And no one but me cares! Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
