budget vacuumforming equipment

[BIRDS-EYE-VIEW.NL]

Maybe this is not the right place to ask for a budget vacuumforming machine. Want to build canopies and airframes with it. So need to be relative big machine but not to expensive.

In case nothing is available. I am wondering if I can use my vacuumtable from my cnc milling machine for vacuumforming.
The pump is quit large (550m3 and 350mBar ) Since a shop vac can work to this is maybe a good start.

So if there are no budget machines I want to build something myself.

Anyone some ideas?

Thanks for your help

an update since the start of this post.

after testing some commercial machines I discovered what is important and what not. I now ordered one of these commercial machines and soon I can vacuumform plugs up to 60 x60 cm
For most cases that will do the job for me.
