BarbaraSue,
I have a Singer 99K that was totally, solidly rusted tight. I refurbed it and it's sewing now. Rusty is what I named him. Currently he wears a hand crank unit and I'm searching for a 3/4 size case for him. He ain't purty no more, but he sews purty good good.
The only difference between his being a piece of junk and functional sewing machine is my willingness to take the time and effort to fix him. He sews just fine and only three parts were replaced. One because I broke it.
I've used as much of his original parts as I could.
I won't condemn any machine just because it's old, worn, rusted ( unless it's like the boat anchor I think Candace posted the pic of) or a non Singer.
I guess it's just an attitude thing. My attitude is I'll fix it if it can be fixed at all.
Remember the 66 head I traded you was a parts machine and I put it back to work.
Joe
