Here's a source for machine manuals and threading diagrams:

All of the old machines thread about the same and require oil in the same places (wherever two moving metal parts touch, except for gears which require lubricant instead of oil). I buy thrift shop machines to fix up for a non-profit and rarely need to look for a thread diagram or oiling diagram; they are all so similar. Here is a link to a diagram that works for many machines:

Thank you so much for your advise. I really don't know how to sew very good. I kind of just fake it. But the last time I tried to thread it, it didn't work. I don't see this model on the websites that you have sent and I can't really make out what they are telling me to do. I know, what a goof, huh? HA! HA! I will just keep on trying till I figure it out I suppose. Thanks for your help though.

Experiment. That's how I've figured out some machines. Be aware that the bobbin thread is supposed to go in a specific direction; one thing you might not think to try is turning the bobbin over so the thread comes off from the opposite direction.

Also, if you can post specifically what goes wrong when you thread it, we may be able to help. If it doesn't form a stitch at all, sometimes that means that the timing is off and needs to be adjusted by a technician; the problem may not be the threading.

Oh, that is interesting! So, it may not be me at all! I like that! I will keep working at it! Thank you!

Lisa,
I have this exact machine but I don't have a manual. Do you have one?

I have the same exact machine, JC Penny 7064 but don't have the manual either. Right now I need the right way to thread the machine - I can find every model except the 7064. Can anyone help?

It probably threads the same as this one:

Most models from the same manufacturer thread the same, especially if they are close in model #.

Definitely made by another company. Penneys, Sears, etc. never were in the business of manufacturing machines. They just had them 'badged' with their name by the manufacturer.

What does your manual say about the machine? Most manuals have a trouble shooting section. Last time you had it looked at? I probably give my machine fits.

Ladies don't forget a few drops of sewing machine oil in the right places too!
