<VV> Cutting Plexiglas-no corvair

[Dale Dewald]

Hello Harry,

I would have to agree with Dave but with your very thin material and long 
strips I would use a table saw.  Try to rig up an extension to the table or 
set up some sawhorses and a piece of smooth plywood as an outfeed 
table.  An infeed extension will also help to keep the material aligned 
with the fence.  A carbide blade fitted backwards has worked best for 
me.  You are essentially going to both cut and melt through the plastic.
