How can I smooth out a rough needle hole on the throat plate?
This is for the Improved Eldredge "B" that just came home. I think the original plate is too far gone to fix; there isn't much metal around the hole. A replacement I found has more metal, but I am uncertain of just how to smooth the hole's edges. Both of these really got bashed repeatedly by needles over the years. (I have to wonder if the needles weren't secured tightly enough, or if the machine has a flaw and can't hold them). The metal might not be all that hard to begin with. How would you go about this? it must be done or the thread will shred almost instantly as it passes through the needle hole. I have a Dremel...
