Well it's taken me 3 hours and a lot of terribly blue language but I have finally got it threaded.
Yep, Ploshkin, I needed to flip a side panel down to find "my next hole"! Lordy, why didn't they mention THAT in the manual!
Oh Jessie, "awkward" looper thread threading is an understatement with this old toad of a machine! I'm going to take photos of all the threading points and make notes as well for my friend.....she's going to have kittens when she sees what has to be done!
Thanks Stitchintime I'll check that out....glad it's not just me being a numpty with this machine. Gosh the manual is just woeful!
Ahhhh interesting you should say that Efemera...in amongst all the debris I cleaned out of the guts of this machine there was a weird looking bit of wire someone had fashioned into a loop of sorts. I must retrieve it from the bin and see if that would help me and my friend next time.....gasp.....does there have to be a next time...maybe my friend won't want it and I can with much relief ceremoniously drop it back to the Thrift Shop!!!!!!
So it's threaded with 3 different colored threads and it is stitching a nice looking overlock on the front but a bit wierd on the back but it's after midnight and I am truly done in......I'll tackle the tension tomorrow. Thanks again everyone.
