Hi Ben, welcome to the forum. If you have access to a decent 3 phase supply, I think that you could do a lot worse than look for a reasonably priced used commercial machine. Many of this type of machine will have a vacuum bed and a tool change facility and are very robust. Good luck with whatever you decide. G.

I only have single power, I can wire into the fuse board, giving 32 amps or 64amps, the cable to my workshop from my house is rated at 64 amps.... this rules out a fair few commercial machines. The space for a bigger commercial machine is also an issue. max height is 2.2 meters and not much bigger than the drawing above 3 meters by 1.5..

im fairly happy about building a vacuum bed. simple 6 section mdf bed.

Hi Ben
It would help if you put some dimensions on your drawing. Some vac pumps are quite big Hp I believe. Clive
