Interesting link. Did you email the guy for a price?
The problem with retro fitting the lee pot is there isn't a cut off valve on the spout.
If the unit is cheap enough you would probably be better off buying it then try to do it yourself.
The temp control, scr's, and heating element could really run up the costs. Then you would have to get the rest of the materials and assemble them.
The piston sounds a little more feasable as opposed to using a pressure blanket (predatorbassbaits injector). You aren't injecting cool air to move the plastic. Not sure how you would stir the plastic for salt or glitter.....
