The plate on mine lifts up it doesn't slide - just wondering if
the domestic is the same way.
another good pt...never thought of lifting...only sliding...will give that a try...thanks...I did notice the plate is narrow so I'm thinking it might be that bullet type now......
Don't be afraid of the bullet types because some types are readily available--just look on ebay. PM Billy (lostn51) here on the board--he'll probably know which one that machine will use and how available it is. I think the clue is if you have one plate it's probably a round bobbin but if you have 2 long plates it'll be a bullet type but ask Billy. I'm by no means an expert!
