<p class="MsoNormal"><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>
<p class="MsoNormal"><span lang="EN-CA"> </span></p>
<p class="MsoNormal"><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>
