Miriam that's where epoxy shines because of it's gap filling properties. Put epoxy in the knob's hole. When you put the knob on the epoxy will flow into the hole where the cross pin was and will mechanically hold the knob in place.

I think I can do that.

[HR][/HR]Junk yard item? Heater slide control from some old jalopy. Acetone will work as solvent to glue some plastics. I would probably put together a threaded nylon standoff from the hardward store, one that wasn't threaded and a screw to go through all of them, to replace the screw/rivet/whatever that is in there.
I tried doodling a diagram here, but it wanted to move the lines all over the place.

(threaded barrel shaped standoff) (unthreaded barrel shaped standoff) looonng screw to go thru.

I have a perfectly good knob off another machine. It fits on there but it doesn't stay. So fill it up with hot glue and slide it on?

Lol, what a bunch of cut ups you all are!

Rodney

Hot glue would work well too. I never think of that one, I don't have a hot glue gun.

I don't have to go buy anything!!!

I think hot glue sounds better than my wood carving idea....

Well hot glue is an easy fix - I don't know if it is the right fix.

Rodney

If you end up with a knob that looks good and doesn't fall off it's the right fix. Or would you rather spend who knows how much time and money looking for the exact correct NOS part in an original box? I'm smiling but there are people out there that would settle for nothing less. In some ways I respect them but I could never do it myself.
