Wow..  this is really cool  (or should I say HOT)

the laminator I got was at least 10 years old..

It has a steel and aluminium chassis

it has a fine temp adjustment on the outside...
coarse temp adhustment on the inside..
a machanical temperature gauge

two sets of gear driven rollers, one set in front and one set behind 

a heating plate over 2.5 inches fron to back...
a heating element 8 inches wide.

Two slight adjustments were needed 

1.  packing the bottom rollers up to compensate for the thicker material.
2.  adjust the coarse heat control to give a range 110 - 200 C

I thought I might need to reduce the speed a little, but...

once the two adjustments were done, boards only need to be run through
once, and reproduction is 100%

Cracked it !   Hooray.

I can't think why I spent all that time ironing.....  !!
