Experimental vac former.

 

Lots of info on the web for making your own canopies etc for planes so I thought I would give it ago.

 

I had a pair of sturdy wooden boxes I could hinge together.

The bottom one was strengthened and a holed plate mounted on the top, this was sealed and holds the connection for the vacuum cleaner to suck the air out.

The top one holds the heat source, at this point a hot air gun but will have electric heating elements (old toaster) fitted soon.

The plastic used for the first test was too thick and not evenly heated enough to form properly.

Heat testing.
