Title: PLUNGER A10 REAR AXLE NUT
Post by: UNCLE CHUFTY on 30 Mar, 2024, 14:34
Could someone help with the dimensions of the 2 nuts on the rear axle and rear stub axle on a plunger A10 , as I'd like to make my own . I know the A/F on the big nut is equivalent to a 3/4 whit spanner and the thread in the same nut is 7/8" 20 TPI.
Cheers , UNCLE CHUFTY

Hi,

It may be better to borrow some to copy.  Where about are you?

Dave.

Hi,

I'm North Lincs so bit far.  There may be someone closer.  New ones are available and in stainless steel.

Hi,

There is a BSAOC group that meets at the Bluebird Social Club, 4 Ham Lane, Longham BH22 9DP
They meet on the first Wednesday of the month at 7pm
You never know you may even join the BSAOC if you are not already a member.

Dave.

Forgive me if I'm wrong but I do believe that the thread for these are whitworth and if I remember correctly they are 20 TPI, as I had to order a tap for these and I still have it, I got it when I was doing the WM 20  bikes
