Hi,

I'm currently building up a RC10T4. I've previously built an RC10B4 so I
have a fair idea of what I'm doing. In building the gearbox, I've noticed
that the idler gear shaft is definitely too large outside diameter to fit
through the two bearings. There is totally no way it will fit. So, I spent
about 20 minutes with the shaft in my drill bit, grinding away at it with a
stone, checking for fit every minute so. Eventually I got the bearings to
fit and the 'box assembled OK.

I'm worried now because there is no way my grinding would be as good a fit
as the correct factory parts should have been, although I was as careful as
my equipment allowed.

1. Do you think there is any undue danger of the bearings spinning around
the shaft?

2. Would it matter?

3. Am I risking something heating up and melting?

4. Should I bite the bullet and order a replacement shaft - I'm loath to do
this because delivery would take a couple of weeks here it Australia and of
course I'm super keen to press on!

Grateful for any suggestions!

Mike
