Was pretty sure the belt drive was the problem, tore it apart and found that the double pulley that varies the ratio was made of some hard plastic, maybe a phenolic judging from the age of the machine. The centre section was cast in two parts but they'd separated and came loose from the bronze bushing that they were to slide sideways on. The bushing could walk over to the side and one of the halves was almost unsupported, and the centres had worn to where they flopped around on the bushing.
The parts listing shows this as an assembly but if someone put it together i should be able to take it apart. Getting it back together is the problem some times.
The side pulley halves ended up being pinned and glued to the hollow centre shaft. The needle bearing it rides on had to be removed to drive the pins through, (new one coming tomorrow, dented the edge trying to get it out), with the pins out used a bearing splitter and a puller to shear the glue joint. Sorry no pictures, my bad forgot.
With it apart I made a new bushing with a larger OD, then bored the centre parts for a sliding fit to the bushing.

Washed it down with acetone then glued the centre together with 2 part epoxy, then installed the end , the halves had to be indexed to fit into the sides.

Hopefully the new bearing will be in tomorrow and we'll have a quiet machine.
