I did the same sort of thing on my Brother. A cone of thead on a stand got caught up on the wheel and wound around. Cracked the plastic cover on the wheel. When I called about a replacement I was informed that to get a new cover on that machine I would have to replace the whole drive shaft. As it didn't affect the running of the machine I used it without the cover until the next trip to the shop where 'the Dr.' epoxyed the peices in place. I sure watch all my machines now to make sure that dosn't happen again.
