Help replacing Plastic Volume Slider on Sega Genesis Model 1

I'm in the process of restoring my Sega Genesis Model 1 from 1989. The case is in really good condition, however, the volume switch broke off many years ago. I have another Model 1 I use for parts because the case is in terrible condition (missing plastic, scratches, etc.). The volume switch on that case is in perfect condition and is perfectly intact. Is there any way for me to move that plastic volume switch to the other case? The volume switch has its "support legs" (I don't know what else to call it) melted to another piece of plastic that rests on the actual slider on the motherboard. If pictures are needed, please let me know. Any help would be appreciated. Thanks!

 

what part do you mean? The plastic slider or pot?
pics will help

 

The plastic slider, not the pot. Let me go take some pictures right now.

 

The plastic piece in question just for clarification:

The joints from the slider melted onto a piece of plastic that rests on the pot:

Case with missing slider:

 

In most scenarios the Genesis Headphone Jack is not for headphones, but used as an output to get stereo from the console to the TV and needs full volume. If the part swap proves too difficult, simply jumper the leads inside to get full volume.

 

Ahh I see now.
Those are called heat stakes, like hot rivets for plastic, very cheap and secure way to bond plastic bits..
What you need is a new box cutter blade, using just the blade, slide it flat along the plastic panel and slice off the end of the heat stakes. You may need a screwdriver to pop the two pieces apart.

Scuff the plastic up with fine sand paper and use JBWELD (not 5 minute epoxy) to glue it back together.

 

Thank you very much! When I get the chance to try this out, I'll let you know how it goes!

 

Well, a few months later and I FINALLY got around to doing it... . It worked a charm! I know this is late but thanks for a solution!
