Yes ! can be used around bottom edge as the vacuum pulls the sheet into place there is a lot of wriggle room with this build about 20mm extra height at the bottom of plug so the PETG sheet pulls past the wanted edge, use small blocks away from and opposite corners that form a ridge. Use talcum powder as a release agent on the plug, the plug must be very smooth oil covered plugs create bubbles. I use balsa and hard foam plug, pull one canopy cut it out leave in place then pulled over the top.
These are two oven elements from old cookers 240v AC direct wired to two 10amp light switches at side so one or both elements can be selected, a safety earth is incorporated and all enclosed - I used the wiring from the cookers. Wired in a 3 pin lead for wall socket. The tin frame is from the cooker back plate with pine board sides. Its not on long so not heating up much. Downside is heat focuses on the centre of sheet and edges are a bit cool, need to heat edges of sheet.
Vacuum former looks great! How did you wire up the heating elements? I'm going to be constructing my own former and I want to know the safe way to wire up the elements.
Looks like it would be hard to fit in that thing! Nice vid though.

@ozziefirebee Sounds good. I think it is about time I try to start making some molds. Thanks again

@ozziefirebee Thanks for the info. Could a heat gun be used in conjunction with the heat elements to focus on the edges?
