In the near future I am going to need to make hundreds of cuts on 1" nylon tubular webbing. What is the best way to cut and solder? Can any one recommend a method or rope cutter in particular that is quick. cheap, easy and reliable?

Any one know the best place to buy large spools on the cheap?

Thanks

Heat up a knife over a camping stove flame. I've done this to cut rope in the field before and it worked fine. Jonathan Dull

Any cutter that looks like this:

We used one when I worked at a sporting goods store and it's stupid simple and does the job well. Cuts and melts your ends at the same time. If you're doing hundreds of cuts then this will be the easiest option.

The device shown above is the best for sure,,but I"ve never found one for sale anywhere. I just heat the nylon slightly, then cut with a very sharp scissors, then reheat, remelt the edges and flatten them with the metal scissor blade on a hard fire proof surface. I've tried the hot knife but it doesn't get hot enough and won't cut easily like scissors will. You end up needing 2 hands to hold both ends of webbing tight, and a third to do the knife cut. Scissors and a flame will do the trick just as well, and easier on your own. Woodchuck ATC

That is actually not the best tool for the job. Some sort of production cutter is...

Depending on how handy you are, you could make one real easy.

This is what they look like.... hand or foot operated.

or go hillbilly style with a sharp 4" piece of metal in a vice grip that you heat with a propane torch. Cut 6 or 8 pieces and reheat. Or, duplicate the device above with some angle iron and a propane torch instead of an electric element. Easy.

Any hot knife that cuts with heat AND pressure will leave your tube ends nice and tight, not hollow or misshapen like the rope cutter box shown above.

I made one out of an old Lionel model train transformer and some nichrome wire.

Will this one from Harbor Freight do it for you?

I stand corrected. I didn't know these existed.

I guess Russ might have cut a few more pieces of webbing than I have.

they all look pricy...worth it IF you are going into the business of cutting and reselling lengths off spools of web. I'm OK with my hot stove and sharp scissors for making maybe 20 runners a year from web. Woodchuck ATC

I stick a utility knife blade in the vise and heat it red hot with a torch. Works really well and doesn't cost anything if you have that stuff around but I also don't have to do cut rope or webbing very often. garrettem

Sounds good, the blade is cheap to replace, very sharp, held in place well so your hands can hold tight the ends of the tape. I just don't have a good workbench to hook up a solid vise to at this time.

The picture in MarkCPA's post shows the one I used for years in an outdoor program. If you can't sweet-talk somebody at a climbing gym or local store (beer bribes?), consider a soldering gun with a cutting tip. The narrower the tip, the better. Your friendly neighborhood handy person might have one in the basement.

Sharp scissors, a pair of pliers and a gas stove will do the trick, too.

But Russ is The Guru on this question.

To acquire webbing in bulk, consider an Army surplus store (military spec) or some place like Blue Water. Or contact Russ.

It works like a charm on ropes.

I use an old butter knife clamped in the vise. With a squatty propane bottle and an old-style burner head, I can set the torch up and direct the flame onto the backside of the knife blade until it's red hot. Then I turn the torch sideways and start cutting. Depending on what I'm cutting I can usually get 6-10 cuts done before I have to reheat the blade.

Maybe not the BEST way to do it, but it certainly works and is a heck of a lot cheaper than anything else linked so far. And I get other uses out of the vice besides cutting rope/webbing...

Try one of these

amazon.com/APEX-TOOL-GROUP-LLC...

on your ordinary Weller soldering gun from your neighborhood hardware store. The hardware may well stock the rope-cutter tip too.

best way yet, that is if you have a vice and a propane torch. I need to cut a few myself for this weekend and have always used a hot knife from a stove burner.

a razor blade and a lighter works OK for in the field

I found this thread as I was looking to cut some 9/16" webbing to sling some hooks, and took the advice to go cheap. I found that buying a cheap $5 pair of scissors and then just using my whisperlight backpacking stove worked really well. Just heated them up and it cut like butter. I had almost convinced myself to by a torch but thankfully remembered I had my stove.

Cut it with scissors or razor knife and then put the cut end over a gas burner until it starts to melt...a few seconds. Remove from heat and smash the edges together with something and the floor. Sealed and ready to go! Adam Stackhouse

+1, the wires a few bucks. I superglued together a simple small hacksaw style frame from some thin bits of wood. Used a computer power supply I had sitting around.
