How-To: Large Homemade Vacuum Forming Machine

From James Bruton of XRobots.co.uk. James’s take on the familiar vacuum forming machine uses a three-layer MDF sandwich for the vacuum box and forming table, with a vacuum cleaner hose connected at the bottom. His heating system is novel, in my experience, using an off-the-shelf quartz room heater at the bottom of an MDF “chimney” lined with aluminum foil reflectors. Sorry, aluminium foil reflectors.
