PVC pipe questions

[MerlinsBeard]

I have a couple of PVC questions for making some props.

I don't have a table saw, so is there a safe way to cut a say 6' slot in the middle along the length of 8' PVC pipe (with clamps and a jig, but starting in the middle) with a circular saw? I've read that I may need to install saw blade backwards to keep material from jamming the blade.

I also plan to drill some perpendicular holes in PVC length wise with a step drill bit, but I'd also like to potentially slightly countersink the hole as well so it's beveled. Is there some kind of cone deburring tool that would work, or some other more special bit? The hole would be roughly 1" beveled to like 1 1/8".

Any thoughts?

PVC cuts well with woodworking tools. I wouldn't reverse the blade - I think that would just result in lots of friction and maybe melting/burning the pipe. Just clamp the pipe down and use whatever guide is appropriate for the type of cut you want. A step bit will ease the corner if you just start the next larger size. If you want more bevel than just knocking of the edge of the hole maybe a tapered reamer. OLD PVC gets brittle so can crack and shatter when cut. New PVC is much less brittle and easier to do this sort of work on.

I have used a chain saw to cut slots on a 14" pipe to use as a sump pit , as mentioned any wood working tools work good .
And also as mentioned older is more brittle and remember to warm it up 1st if bringing it in from outside.
A jig and a circular saw will work with a combi. blade but in my opinion don't use a very course blade

I think a cutoff wheel would be pretty good precision cutting in PVC

I agree.

I typically go for a plywood blade. Finer tooth count.

Any fine tooth saw should work fine. I've even cut PVC with nasons string when in a tight spot. Sawing motion generated heat and it melts on through.

I think a cutoff wheel will heat up the PVC and won't work very well. I haven't tried it but that's my guess. Some sort of cutting teeth works well.

If you are worried about the saw getting away from you, consider a jig saw instead. I think a circular saw would be fine so long as you create a jig/fixture to keep things under control.

PVC Pipe can be forgiving, but don't bet on it.

A jig saw would work very well, especially on a pipe as big as they have. Use a medium tooth pitch. Just drill a hole to start and cut whatever shape you want. Will be very easy to control.
