[Healeys] Drum Balancing

I had Autofarm balance the rear drums on our BT7 and the difference was so great I  had them do the BJ8 and BN1 as well.
They use an "Add and Subtract" system on the worst drums, adding weight to one side and shaving the other. While this may not look concentric to the drum, the difference in shake is significant and the change is invisible with the wheel on.

Can someone clarify a few of the comments on drum balancing.  A couple of people said they had them done by various specialists on a lathe by skimming the fins.  This will make the outside of the drum round, which I imagine must help, but that is different from balancing, which I understand may involve subtracting and/or adding weight in strategic places, as one would in balancing a tyre.  I don’t think balancing can be achieved simply by truing the outside of the drum, but I am glad to be corrected.  So by drum balancing, are these wonderful accolades a result of drum truing or drum balancing?

One major thing to keep in mind when having someone balance your wheels or shave your tires is how they are mounted on their machine.  Wire wheels must be mounted on the machined surfaces not just with internal cones as a company that does not normally balance wire wheels would do.  It won't do any good to shave the tires from the wrong center.

So a specialist who understands British wire wheels is essential to having the job done properly.  Besides Hendrix there is K & T Vintage Sports Cars in Bethlehem, PA owned by Ken Beck, an Austin-Healey owner.  Check their website at http://www.ktvintagecars.com/ for a video of the tire shaving process.  I have some new tires for my MG wire wheels that I will have them mount and balance, and shave if required.  I know Ken, but never had any work done by him.  Others have great things to say about the process and their work in general.

I had my drums balanced several years ago by the local NAPA machine shop who do my engine rebuild machining.

Another satisfied customer of Hendrix Wire Wheels.  Mounted and balanced my Dayton wheels, shaved the Michelin's and balanced the rear drums.  Had it up to 104 mph on our speed run last summer (It's got a V8 but the rest of the suspension is stock Healey) and was smooth all the way up.  Drives at 2,000 rpm at 70 mph with its five speed and it's just a joy. Time for new tires this year and they are going back to Hendrix for the treatment.  Probably the most satisfying money you can spend on a Healey.

Ditto on both of my Bt7 and Bj8. Remarkable difference after Hendrix Wire Wheel in Greensboro NC got a hold of them. I think he can shave tires also. Great to work with also

Allen Hendrix of HendrixWireWheel (in North Carolina) did my BJ8.  Rear Drums and (I think) the drive shaft.  I don't know exactly how it is done.  I always just hand the keys to Allen!

Smoothest BJ8 I've ever driven, including 2 purchased new back in the '60's.

Where did you get them balanced and how was it done?

Absolutely!   Eliminated 50-70% of scuttle shake in daily driving.  One of the best things I ever did to my cars.  Have balanced several sets.

I can understand balancing the front drums on my BN2 to help preclude scuttle shake, but I am converting to front disc brakes.  Is it necessary to balance the rear drums?
