This is the trouble with mine, If I can't get a good reading in the lathe,
With the old stuff, What chance do I have after welding and stroking !.
I see now it's been said the centres could be out,
This is why I sawed a mainshaft in half, To put the 2 wheels together with most of the balance holes,
also with bits of tubing, To try and set it up for welding the wheels together,
Ready for boring, Scared it will be miles out !,
But must give it a try, S--- or Bust !.
Looking at some youtube stuff, They seem to hold a lot of faith with the old ,
Straight edge across the outside rim.
Some of the youtube stuff with the H.D. s is rubbish,
One bloke bashing hell out of the wheels while still with the dials on !!.
I still have in my " Head " a view of a friend of Bob Dunn's,
Who worked in the next shop, Putting together a pair !! of flywheels,
Fully together they just spun in the hand, ie loose on the taper,
So would just rely on the nuts and bearings to hold them true
,
Wonder what happened to that bike ?, Not a Vincent, Thank God.
I will try John's idea of checking the chuck,
Good Luck, Bill.
