I lowered the V-cam so that it is as low as it can go and not risk jamming.
I also switched the V-cam for the spare that came with the machine. The one that was in the machine showed signs of wear in one spot where it seems to be rubbing against the cylinder
The yarn guide:
- try a different yarn
- get new needles - Angora Valley Fibres has them for sale.
- and as a final effort, find a mentor. A few people have been in touch, but all of them live out of town. But I suspect there are enough people in Victoria who are interested in learning about these machines. Some of them even have a machine or two in the basement waiting for guidance. Maybe some sort of clinic or workshop is in order?
