Mel - that's great news! Hope it continues to go well for you, the new drums button-up perfectly and require minimal to no truing. Also hope you are able to return the stud removal tool and save the $$$'s!

Steve and others. Well today it all happened. I took the old drums with the outside mounted hubs to a local machine shop. We took one drum and using an endmill in a milling machine machined off the stud heads inside the drum. The studs then pressed out very easily. there was a distinct swedge area where the stud was pressed to the hub. As I mentioned earlier the swedge was flush with the hub surface. Therefore pressing out from the inside seems to be the best approach. After removing the 5 studs it took a slight press to press the hub and drum apart. What comes next is to attach the old hub to the new drums and swedge the stud. I will; report on this when we do it.

Thanks Tom - having never used this particular tool before this is good info to have. Have used similar tools that amounted to hollow reamers to clear swedged bolt shafts internal to the holes only (without increasing the hole size) on other more modern/later applications. Thanks for sharing.

Steve, I see no need to remove the swedged area id the heads are ground off and pressed out from the inside. My answer was to clarify the use of the tool. The amount removed from the hub should not make any difference to the strength of the hub. Either procedure will work.

Mel - let us know how you make out. Will be good info for all. TomO & Mel - thanks for the insight and (for me anyway) education on the differing lug sizes as well as the tool application. Hopefully in the end you will be able to return the tool Mel and save the $'s.

Steve, Thank you for your concern. I will start by removing head of stud inside the drum and pressing from the inside with full backing on the outside. Then I will decide how to proceed but most likely will continue to work from the inside of the drum. Thanks again Steve. Regards, Mel

Tom--I realize there are 2 diameters. The .56 was used with hubs that mounted on the inside of the drum. The .62 was used with hubs that mounted on the outside of the drum. I'm not in my shop now but I believe the od of the cutter is .62 the same as the stud.
