With the talk on Kate's post about Serge's woes, I too have a question.
I've got a White 3/4 thread, inexpensive serger (was all I could afford at the time) and it's about 2 years old. It made a nice overlock stitch and pretty rolled hem. I had put a thick wad of corduroy through it (I know, I know) and it went "kerchunk". EVERYTHING locked up, choked up, and my little serger went into arrest.
I took it to the local SM man and he got it to stitch (after alot of time) but it will not sew a pretty stitch off the bar and it sounds like it's barely hitting something (like misaligned). Believe me, DH and I have peared into the bowels of this machine for long periods of time, turning the handwheel, and trying to see what's misaligned. We can't find it. It WILL serge properly but will occasionally skip some stitches. I'm still using it regularly. I'm not taking it back to the SM guy, because he's at a loss on how to fix it. I'm going to change the blades (again) and see if that helps.
I'm concerned it's wearing something down, plus the fact that the occasional skipped stitches irk me and it won't chain off the bar (without fabric).
Any ideas?
