[Shop-talk] Cutting canvas rolls?

[eric at megageek.com]

I don't know if you are near NJ, but I have 2 massive bandsaws (one wood 
and one metal) with fine tooth blades.  You're welcome to try them.

If not, one crazy idea would be to fill the core so it's solid, and visit 
your local fire department and see if they can use their jaws of life 
cutter on them. 8>)

Yes, from 12' long down to 4' long.

They tried unrolling and it's many dozens of yards long so that got shut 
down quickly.

I have never seen a four foot utility knife :-)

An electric turkey carver is my goto for stuff like foam but the canvas is 
stout and I don't see it working. 

A rotary razor is ideal, but the best I can come up with is a disc grinder 
which doesn't have the depth. 

Thanks for all the ideas so far.
