Hendrix welded more material to my drums as needed and it seems to have worked fine. I would not like grinding off material as it might affect the integrity of the drum by making it thinner, effecting the heat distribution and strength. Just some rambling

A different shop welded rod material onto my current BJ-8’s drums to balance them. I think these drums were more out of balance than on prior cars. They were careful to call me ahead of the operation to ask how much clearance I had between the wheel and drum,
and I was able to take them a wheel and hub so they could see how it all fit together. The results are just fine, also.</p>

Another consideration for balancing the rear tires is the brake drums. I have the original BMC brake drums and was surprised at how out of balance they were. I static balanced the brake drums to go with the separately balanced wheels and tires. No vibrations,
shimmies or skuttle shakes so far. </p>

<span lang="EN-CA">I made up my own adaptor using a used hub and knock-off (spinner). I had a machinist mount the hub on the lathe and ensure that it was true on the inside edges (where the bearings fit) and had him put a slight chamfer on the edges to provide
better registration for the standard cones on a modern balancer. Then we machined the centre out of the spinner so that when the wheel is mounted on the hub and the spinner is tightened, the outer cone on the balancer fits through it and registers on the
hub. That part is a little tricky as if you machine the hole too big, the spinner will end up in two pieces – measure carefully! Hub and spinner was $25 at a swap meet and machining was $50. I believe this adaptor will work on any post-war wire wheels except
the Jags, which had different hubs. Worked a treat on my TC wheels. Healey is running vibration-free- so leaving it alone for now.</span></p>

<span lang="EN-CA">I too liked on-wheel balancing and in my simple thinking it balanced the drum or disk at the same time – as long as you remembered to mark the position of the wheels when you took them off and did not rotate them (to a different position
on the car)! That is likely one reason they are not used anymore, because if your drums were out of balance and you added weights to the wheel that balanced them out, then every time you removed the wheel, you’d loose the balance, unless it went back in
exactly the same position. Anyhow it’s a moot point as I have not seen an on-wheel balancer for decades. I imagine that disks run very true anyhow, but when I balanced the drums on the TC they were significantly off. I hear balancing Healey drums brings
good results, but never felt the need as my BT7 has always run pretty smooth. If anyone in Ontario (Canada) wants drums balanced, Garland and Sons in Scarborough did great work for me.</span></p>
