What, if any, is the fix?? Anyone know what the minimum thickness is or
the maximum i.d. is for these old drums??
Any help or guidance appreciated.

I think 10 thousandths over is the limit. Could be wrong on that. | | | | | Joined: Apr 2008 Posts: 899 'Bolter | | 'Bolter Joined: Apr 2008 Posts: 899 |

I've got the '48 to '53 Chevrolet Truck Shop Manuel. I guess what I need to give to NAPA or any shop that will attempt to rebore the drums is the "standard
diameter" of a new drum. With this information the shop can measure the inside diameter of my drums with a micrometer and determine if there is enough metal
left on my drums that can be rebored without going over .060 oversize.
If that information is in the shop manual, I've been unable to find it. Since no figures are stamped on the drum, the shops won't touch 'em. And, I guess, for
safety reasons I don't want the drums rebored outside of limits.

| | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Jerry Bubolz, the standard size of half ton drums in 1949 is 11", hope that helps. | | | | | Joined: Sep 2014 Posts: 120 'Bolter | | 'Bolter Joined: Sep 2014 Posts: 120 | Thanks for the confirmation of the 11" standard. Just now I went out and measured one of my drums. I don't have an inside mike but I'll bet $1 that
the i.d. of these old drums are way over the 11" plus .060 allowable re-bore.
I'll take the drums into NAPA tomorrow and let them measure.
Thanks for the help 3B.
