Hi Whitworth Heads,
Just realized my response below only went to Mark, but it was intended for
all. Merry Christmas to most and Happy Holidays to the rest.
Cheers, Peter

Subject: Axle eye repairs and camber
Hi Mark,
Thank you for that report. I was one of the original participants on this
thread and the proponent for going to the larger king pin option. When I
get around to tending to my axle's eyes, not seriously bad but far from new,
I'll be even more so inclined to make oversize king pins. Granted the next
owner will get upset when a proper replacement pin doesn't fit. So while
I'm at it, I'll take the insignificant extra time and money to make up one
or two extra sets of pins and strap them to my original steering box and
column hanging in the garage where it is nice and safe (like guns - out of
reach of children, and the socially responsible thing to do
). On
second thought, expressing such an opinion is not the politically correct
thing to do on this list, I know.........
That is, unless I learn more about the benefits of changing front wheel
camber. I seem to recall someone saying the racers do this. Stock TABCs
use 3 degrees positive camber, which gives them that classic or charming
stance when viewed from the front. However, I've always been curious what
lead pre-war chassis engineers to this bizarre geometry. Does anyone know?
I'd love to read a good explanation from the point of view of the tyre's
contact patch and cornering forces. That said, if handling can be improved,
then the heat necessary for swedging the eyes back down to 3/4 inch ID would
be handy for changing the camber angle at the same time.
Cheers, Peter

This was because after shrinking, the repairer claimed that the eyes
were harder than they were originally and didn't want to run reamers
through them. I cleaned them up with a two legged brake cylinder
hone. As I said in my earlier posting I had to go back to them for a
bit of touching up when I cleaned off the high spots. The final fit
didn't require hammering in, this would make it difficult, if not
impossible, to assemble the pins and knuckles on the car. They need
to be a firm push fit or light tap fit.
