I am having a recurring problem with the above machine. The bolt
attaching the drive pulley wheel to the back of the drum keeps
working loose. It is 'locked ' using a mild steel plate with its
lugs bent over the flats of the bolt head. The plate is so soft
it doesn't hold for long.

Is there enough spare thread on the bolt to use another nut
a locknut against the original?
