How to cut PVC straight


It always comes out slightly crooked when I use this method. Usually good enough for the job, but not perfectly straight. What's the better way?

Can I use a mitre saw?

Re: How to cut PVC straight


chop saw, circular saw or jig saw will do a straighter cut.

Do they clamp it to something? I was just holding it with my hand.

I've had PVC explode in the mitre saw before. But maybe the blade didn't have enough teeth.

Only because you were to nervous to hold it tight.

Re: How to cut PVC straight


Build yourself a V block to lay the pipe in. When cutting by hand your shoulder and leg/hip should be directly in line behind the cut. A fine tooth blade with long even strokes usually produces the best result. A rip tooth saw preferred if you can find one. With a few practice cuts you'll look like an expert. For PVC I prefer a pull saw over a pusher because those prevents the operator from exerting excess pressure that causes crooked/wandering cuts.

Re: How to cut PVC straight


For 2" and smaller- https://www.amazon.com/Jones-Stephen.../dp/B005NITKPU
Works especially well on tubular PVC when assembing traps and contiuous wastes.
Larger pipe - https://www.amazon.com/Manual-Pipe-C...0SG9SSE6DZ4SFT

If you don't want to invest in these- use a sawzall with a fine wood or metal blade.
Avoid any thin blade that flexes

I probably would have done better if I had my large hacksaw. But it's in storage.

Re: How to cut PVC straight


My miter saw is first choice if it's set up and convenient to use. But can cut it with practically any saw that you own. I did pick up this PVC saw many years ago and it still works good. This one is made by Starrett, but Lenox also makes one.
When using, assuming you get the cut started straight, it will finish straight. The depth of the blade makes it impossible for the blade to wander like a hack saw might.

Rolling the piece being cut makes for a straighter cut.

Wiseman say 'level end with a belt sander, then hand finish with sandpaper'.

Found this in a fortune cookie.

Re: How to cut PVC straight


Plumbers have a hand held battery operated shear that chops up to 2” pvc. If my chop saw is at the site, I use it but pvc sawdust is a pain to clean up. I cut outdoors and clean up with a leaf blower.

Ouch, you'd better believe it. We installed 8" base throughout an entire house of PVC at the customers spec. Luckily it was a new house with a garage that we could cut in. It contained the PVC "dust" so sweeping wasn't too bad. I can only imagine if we had done it outside in the grass
