HI

how did you melt it

I didn't clean the compound, but I can see how it was done. The body is sawn along the perimeter, the compound is mechanically picked out, then the body is glued with "Poxipol" glue. I will take additional photos of the sawing.

Photo of the tracks under the processor in case you damage them when removing them. The processor is firmly glued, difficult to remove.
