I gave my 1951 Featherweight to my older daughter who wanted to learn to quilt, and she's hooked! I greased and oiled the machine before she got it and it ran like a top. Then it developed the dreaded stitch lock. In attempting to remove the bobbin assembly to check for a stuck thread, I discovered that I can't remove the gib screw. I've included a picture of the problem screw (that's not my machine--mine is in much better shape). My DH has tried WD40, wait time, and his best Craftsman screwdrivers, but no luck. The screw won't budge. We finally took it in to the shop where the SMG admired the FW's overall condition and then said he'd try to get the screw out, but he may not be able to. Anyone here have any suggestions?
I tried to post a photo from my iPad, but I've never done this before, sorry.
