Rear Drum Replacement Stripped threads.

[belvedere666]

my '50 plymouth has a 10" drum and the threads were stripped out on the Righthand side! isn't usually the Lefthand threads that people screw up?

I happened to have a rethreading tool and i rethreaded the lug holes. they hold a bolt alright but the car isn't roadworthy yet so i have yet to see if the "new" threads are strong enough to work or if i should swap the drum. i'm looking into getting the studs that Deathbound recommended to be able use different rims but they still need to be threaded. anyone have any experience with this and if replacing the drum is the only option, anyone have one they're selling for less than ebay and/or kanter at $125?

Worse comes to worse, you could use heli-coil to repair the stripped threads.

would that be strong enough and make it road safe?

I now its not the correct way to do things but I'd get some wheels studs, here in Oz it was easiest to get Frod ones and drill the threads oversize to suit the studs and press them in from the inside, I used the standard Frod 1/2" UNF all round and never had to worry about left/right hand threads again.......or at least until I hot-rodded the car and went to 4wheel discs in 1975.........lol............I'd be a little hesitant about using helicoils on the brake drum, I suppose they should be o/k but maybe one but not all 5 threads..........andyd

Stay away from Heli coils. they require a hole with a bottom to lock into......Find thread inserts.  You drill the 7/16 hole out to 5/8 and then screw in an insert. the insert has 4 pins that you then drive in an thus locking the insert.

I hate any heli coil....

Wouldn't press in studs be the way to go

IF I were to use heli-coils in the drum..I would insert them as normal BUT from the inside ..then I would use proper length bolts( as used for racing bolts and lock them in place giving you studs)...that way you have saved your drum and at the same time coverted to studs...and no longer worried about LH threads

Torque the ones in question to the recommended torque....if they torque up, I would think they are good.
