If it is 10 foot I wouldn't care if it only took 1/2 sheet.. of 4 X 8 that is.
I love Springers 1 sheeters, but till now they were too small for me although I am going to build his OST... may scale it to 200% and glue 4 sheets together to make one sheet. It would be interesting to see if his design would make a 200% out of $tree foam.
I would bet it would with very little modification.
Now we got Ray... anxious to see what he does.
