[Shop-talk] Cutting canvas rolls?

[Pat Horne]

I’ve also seen paper shears in print shops that can cut close to a foot of paper, might look into that but it would require taking the rolls somewhere.

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.
