No, I don’t have an answer. Hoping someone else did.
Maybe an electric knife? or a big razor knife?
I have a roll of 56 inch that I’d like to cut into to 28 inchers. Actually, I’d like to cut it into two 30 inchers, but that might be tough.
thx
Greg,
I remember years ago Greg Loehr telling me how they did this. You tape around the roll (both sides of center) and cut with a sharp knife such as the one’s with the serrated blades. To date this it was when the ads were on the tv for the “Ginsu Knives” as I remember him joking that they were good for something. You might be able to do this with an “OLFA” rotary cutter as well.

Wrap the cut area with wide 2 in Masking tape, put about 5 or 6 wraps on it. Hold it real tight and take a Sawzall to it. Maybe use a metal blade for a finer cut? I will destroy a little cloth at first, but once you get into the roll it should cut real smooth and fast. Obviously wear a mask.
I would just cut the cloth as it comes off the roll, myself. Keep your Dritz electric scissors handy, takes about 2 seconds to cut 10 feet.
I’ve heard of wrapping a band of tape around the middle and running through a bandsaw with a fine tooth blade.
hey greg
i did this on my first roll
with a razor sharp kitchen knife like a chef would use
the roll was taped closed
but i didnt use any tape where i was cutting
i think i recall i turned the roll as i was cutting so the cloth
was cut through all they around before i cut through the tube
if that makes sense
big savings but its most likely volan at that width
I agree with the tape, but I’d try a porta-band on it instead of the sawzall. Continuous would be better than back & forth. Find someone who does on-site metal fabrication, he’ll probably have a porta-band. Drive around & look for people fixing roll-up doors, fences, loading dock equipment…and have the universal currency available ( a good 6-pack ).
You also joke about 2 30" 'ers, but you indeed might want to think about your cut. Cutting 2 28"'s would be easy, but is 28" enough to do a 2" cutlap around the rails of a 23" wide, 3.25" thick noserider? (Hint, I know the answer, its No. Don’t ask me how I know.) If it was me, I’d probably cut a 30" and a 26". Even the 26 will still be enough to freelap a shortboard, and you can use the 30" for any cutlaps or longboards you do. The 26" would be enough for any 1st layer cut to the edge of the deck, when thesecond layer wraps over it & around the rails, or for an inlay layer inside an already-done cutlap.

I love Swaylocks. (um, the web site)
GREG,
2’’ TAPE REAL TIGHT WRAP, MARK THE CENTERLINE ALL AROUND, THEN USE AN ELECTRIC KNIFE WITH TWO RECIPROCATING BLADES, CUT TO THE CARDBOARD TUBE, THEN HACKSAW THE TUBE. DID IT FOR YEARS.

Not a bit…but if you buy a porta-band, you’ve gotta hook a brotha up at Christmastime (which means bring it up in the car!) 
Heck, you’re doing enough welding these days you can probably justify the love. Couple shaping-rack jobs around your neighborhood and the thing is paid for…
in stead of tape try shrink wrap it works better but wrap it three to four wraps if you have a sawzaw take and grind a long blade sharp and smooth make sure you cut straight
OK everyone, 10 really great ideas. Some variations on a theme. I’ve decided to cut my roll into 10 pieces 5 inches wide. That way everyones idea gets a chance. But I’m going to need some help laminating with 8 inch strips.
Really, I’m going for the tape or shrink wrap with a reciprocating double bladed electric knife.
Thanks to all.
Thanks to this post I tried cutting a large roll of glass (I went with the tape/hacksaw approach) last night. It turned out so well. Very minimal fraying of the edges (much less than with scissors). I wish that I had know about this a long time ago!
