For a project I am going to make a marble machine. The track I am going to be using is either 1/2 or 3/4 scheduled 40 PVC. I’m not sure what tool would i be using to rip the PVC. Maybe a plastic jig saw blade?. Thanks for any suggestions.

make a ‘v’ grooved board
and clamp it in front of the bandsaw blade
centered

lay the pvc against a straight board
and draw a line along it

then keep the line up
as you run it thru the bandsaw

Fit a blade specifically for PVC to the table, I think they are negative rake and similar to a aluminum cutting blade.

Other wise do a test cut on some scrap and you may be comfortable with the result.
I cut perspex and lexan all the time on the table saw.

I don’t have a table saw, or a ban saw. Maybe i can make a little jig for a jig saw with sandwitching 2 2×4’s and use my jig saw.. Or i maybe i should “Man up” and buy a table saw… Thanks for the suggestions so far.

Band saw.
Table saw if you have an affinity for taking chances and doing dangerous crap.

But the first question should be, “Why not make the tracks out of wood?”
A “V” groove will work better than a round groove; less friction. And easier to make.

I would also make the V groove on the table saw.

I have to go with crank. “But the first question should be, “Why not make the tracks out of wood?”

Bingo: he nailed it.

Tell us what tools you have, Chetrog. I gather that you have a jig saw, but that seems like the worst choice to me. the reciprocating action would be too unruly in my opinion. You could use a Circular saw, but then the need for a jig becomes more pressing.

I’m a little slow since i had a stroke. I guess i don’t understand what the v grove that people are talking about. gonna google it now.

I own a Circular saw, mitter saw,drill, driver, and a jig saw.

For safertys sake and for a person in your condtiton, stroke, I would build a jug that I could cut small diameter pvc with a utility knife. Something you could build on the jugsaw that would hold and clamp the pipe with a metal straight edge to run the knife along making several passes then turning the pipe 180 deg. and doing the same. I personally would stay away from the table saw for small diameter pvc. I have done it on larger size like 1 1/2” and up and that can get a bit scary. But each to his own, just one of the few things I wouldn’t do on a table saw.

I don’t understand the end result, but if you’re trying to rip a pvc pipe in half, I’d go bandsaw as well. You’d probably be better off with a metal cutting bandsaw as I think high speed might melt the pipe and gum up the blade and tires. But I never did it so I can’t say

Just kind of thinking here. DOn’t take it as gospel.

A V-groove is just two cuts with a table saw to make a 45° angle that sits on it’s point, like what welders and machinists do when welding pipe….. Set a piece of Angle Iron on it’s point and lock it in place, put the piece you want to cut in half in the angle and it won’t move.

YOu can make one with wood by using a table saw or a router, possibly a circular saw, although with the stroke you may not be able to hold the circular saw steady.

I would take available jig saw, cut a slot in a piece of aluminum angle and then put in a wood blade to or pvc blade in the slot. Hold the angle on it’s point with several F clamps or even C-clamps and a piece of wood on the top. If the angle is large enough, the pvc will slide under the clamp.

Thanks for the information guy. I had a stroke about 3 years ago , for me just explaining stuff gets hard to understand. I can still use tools etc, thankfully. Thanks for all the suggestions.
