[Shop-talk] Cutting canvas rolls?

[Pat Horne]

Jim, try an electric knife with a serrated blade. The blade may not be long enough to go all the way through in one pass & almost anything you try will give a rough cut. 

I doubt putting a circular saw blade on backwards would cut through canvas, but it works well on materiel that melts. 

To get a toothed blade to snag less, tightly wrap something around the roll so it is closer to a solid piece & it won’t snag as bad. 

Peace, Pat

I have a friend who has 3 12" diameter rolls of coated canvas she needs to cut into smaller lengths. They tried hand cutting with a toothed blade but the teeth get caught in the canvas threads and tear it. I have a sawzall but I don't know if the blade speed will be fast enough to overcome the pull of the threads. Is there a non-toothed way to cut this? The rolls are 12 feet long now and quite heavy, 2-3 people to lift, so a floor solution would be best. 

thanks,
jim
