How are you using tire weights to balance your brake drums currently?
As a practical matter if I was getting bad vibration at a corner and thought it was due to brake drums and I was using beads I would try rotating the wheel 180 degrees on the hub so that the out of balances counteract each other.
At least until I could get the brake drums turned and balanced.
Find a shop that stilll has one of the old machines that balance wheels on the vehicle.
They run the wheel to find the best balance, as stated above by rotating the tire until they get the least amount of weight difference. Once that is done they then balance the whole assembly. Once everything is balanced they mark the rim and one of the studs, so the rim always goes back in the right position after being removed.
You will probably have to search out an old timer in an independant shop, to find somebody that knows how to use the machine.
The other way go, would be to take your drums to a shop that balances drive line parts. This route in not cheap and the number of shops doing this type of work are becoming in short supply. The shop that I used to balance drive shafts went out of business about 15 years ago.
