Alright, /diy/

I've got some woven conveyer belting (pretty much the same as pictured). I need to cut it perfectly in half. Does anyone have any idea how I should go about this?

I was thinking I could just go very slow on my table saw with a couple of friends helping feed it through while I held it flat.

Any suggestions would be great.

straight edge and a utility knife would probobly work, you could make a simple frame out of wood that you could use to guide the knife perfectly down the middle, I'm assuming you mean length wise. You would probobly have to make a few passes, so lightly score first time, then go a little deeper

You do realize that a single cut will cut it perfectly in half every time right? just turn it off and cut.

Try taking a couple of 2x4s and place them next to each other with a gap in between. Then use a jigsaw to cut down the gap.

It's a very long piece. About 22', and half an inch thick.

What do you mean?

I found a picture of the actual piece I have on my phone if it helps.

Bump.

Come on guys, if I can get an answer I'll explain the entire drive system for the vehicle I'm building from scratch.

please do, but just measure out the length and cut it down the center with a utility knife. it's not too tough

The belting is for a paintball tank I'm building. About 8' long, 4' wide. Anyway we basically backwards engineered a transmission commonly used on scaled tanks called a Mantra.

From the engine goes a belt to a Peerless 5 speed gearbox, and then back to what I call the neutral axle. Basically allows the engine to be on without actually spinning either track. This is required for turning any tracked vehicle.

actually I just googled around for a minute, and that is pretty much the best way, but it will take forever. The stuff is tough, and apparently if you try to use a table saw, circular saw,ect. it will just gum up almost immediately. I was thinking maybe a hotknife harbor freight has one for about $15 it's 130 watt, or pic related with one of the different knife blades available for it.

Each track has its own drive axle with a pulley, attached to the neutral axle via another belt. It is driven by tensioning the belt. This can be done independently on either side to allow turning.

>> No.18768

The belts are a special belt called a Davy Belt, which is a belt/chain hybrid to cope with high stress involved with turning a tracked vehicle.

>> No.18822

Alright won't use a table saw then. What about a hand saw or hack saw? I'd rather not have to spend money if I don't need to.

>> No.18858

Bump
Any other suggestions earns you a free question about the tank.

If you know anyone with a Festool or Hilti saw with guide rail, just turn down the RPM and it won't gum up. Low RPM and slow feed are what you need
