Hi Geoff,
Traction tyres or no.
Call them what you will. But the wheels are two piece, with
inner spoked wheels and a seperate wheel flanged rim approx.
.125" wall width.
(As all full size. prototypes). However the Aster,
s rims are probably stainless steel as you said, and maybe
machined from tube.
Maybe it
was the electrical insulation melting out. I never thought of
that. (The seam is around the o/d of the inner primary wheel )
i.e. Press fit joint line around the rim. The
inner wheel o/d rim and the inner diameter of the tyre also has
2 ?
degree angle across the width, so easy to re-fit and self
centering, without any wobble.
I guess I replaced the insulation with the Superweld
Metalised Epoxy, which may not be a very good insulater. Which
is OK, as I don't like those horrid little volts running through
my track!.. Having said that, my U1
is so quiet it may as well be electric powered anyway.
I would willingly knurl some treads on your tyres, if I
had a lathe. I am already looking. Just do not expect
the knurls to be full depth diamonds!.
I surmise you also are have had traction problems with
your KGV.?
I added approx 2 pounds wieght to mine, now it has a natural
wheelspin at startoff, not all the way round my track. It could
be those heavy J&M coaches
as well.
Feeling Chuffed!,
