The 8 foot x 12 foot vacuum lining table I built in 1989 for less
than $5,000 has worked problem-free for those 22 years.  Heat is
even. It is wired for two heat and two vacuum zones (use a half or
the whole)

Components:

    Single 0.5 inches x 8 inches x 12 inches aluminum plate

    Thermal Circuits Inc. custom sized, etched foil/vulcanized
    rubber heating blankets (still available)

    Two Ametek Lamb vacuum motors Model 115937 (still available)

    Vacuum motors controlled by Lutron T-1500 (1,500 W) dimmers
    (still available)

    Heat controlled by Omega CN6071A-J process controllers (newer
    models available now)

    Omega thermocouples
    Omega relays
    Magnahelic pressure gauges (inches of water)
