i need to cut a bunch of conveyor belt, 1" thick. I'm not looking forward to using a box cutter/razor knife. The strips will be 8' feet long and 3-1/2" wide.
a lot of assumptions without actually knowing how the material reacts to a spinning blade.
Metal vertical bandsaw. Slowest blade speed (so you don't heat the rubber). Use a fence of some sort. Will take a while.
Let me see if I have this straight. According to you, if someone doesn’t have actual experience in cutting 1 inch thick conveyor belt that is 8 feet long, then advice should not be given because without firsthand knowledge the advice may be all wrong. Is that what you said? I guess that would leave out helpful advice as well because without actual experience in cutting a conveyor belt of this length and thickness, any advice would be just a guess. Also, according to you, anybody without firsthand knowledge is simply commenting so they can make a post.Which is generally what happens on forums...people post just so they can post, and don't have any actual knowledge or helpful advice.
8 feet long...have fun with that. I cut conveyor belt often, but not an inch thick and not 8 feet long. However, I use two pieces of flat bar stock, clamped across the belt, and a razor knife. It's the only way to get a perfectly straight cut. Good luck finding two 8-foot straight edges.
If you want to take the time to set it up, and have money to burn on wood, I'd use two pieces of plywood or whatever. A common technique for making cuts where you want zero tearout is to sandwich your workpiece between two pieces of wood. Clamp it on top and bottom of where you want your cut, then cut through the wood and the rubber at the same time on a table saw or with a circular saw. You'd have to be really careful, and go at it slow. Being an inch thick might make it stiff enough that a band saw blade would go through it fairly easily with the right technique and a good blade. Use a blade made for cutting metal so you'll get a cleaner cut, and keep it lubed with something..silicon spray or something similar.
My biggest worry would be that any powered blade will create heat, and if you heat the rubber too much the blade will bind...which can cause all kinds of problems.
I've cut 1" thick rubber for motor insulators with a tablesaw plenty of times. It's not a big deal.

"Chainsaw"? I can just imagine the kickback on that! I think quadrcr87 is into blood and guts.
