Plastic repair
I have a question for some who might know more about plastics than I do. That would probably be most of you.
I'm working on an Emdeco Mdl LT-72 ZZ and multi stitch with cams machine

and the hand wheel is cracked. It's plastic with a steel sleeve in the center. Here's a pic of it:

The plastic is hard, kind of like PCV, but I really don't know what kind of plastic it is. I'm guessing it's from the 60's or 70s if that gives someone a clue.
Once I find an adhesive I'll glue the crack, then clamp it tight with screw clamps till it cures.
OH, yeah finding a new one is an option I'll be following, but I won't be holding my breath.
Thanks.
Joe

Plastic never really properly can heal; especially since it will be receiving torque whenever the handwheel is touched/moved by hand. I would not only epoxy it, but also create a permanent brace around the circumference of the wheel. Think of a dental retainer, or a large hose clamp, but obviously something more attractive than a hose clamp.

I haven't done anything to it yet. Still cogitating on it. Next time I go somewhere I'll take the hand wheel to the LSMG and see what if anything he might have.
I have no idea what other brands of machine this one might share parts with, but if anyone here has an Emdeco that's dead and has a good hand wheel, we can compare notes and maybe work a deal.

Drat, nope it won't fit. The center hub is offset way more than the one from the Emdeco.
Good idea though.
