davelin315 November 28, 2009 November 28, 2009 I've been trying to cut 6" PVC with my mitre saw but since it only goes halfway through before getting stuck, I'm getting uneven cuts and am forced to smooth them out by hand which is at best a crap shoot. I don't have a band saw (might change) and the table saw is the same, I only have a 10" blade at largest on any of my saws, other than a sabre saw which I might as well just crack the pipe and go for it. Even with the band saw, what are you using to ensure straight cuts? Do you rig up some sort of jig or put it on rollers and spin it? I can smooth it out with a router after, but that's also something that I don't think will help much since it has to be more or less flat to begin with to do this.

flowerseller November 28, 2009 November 28, 2009 Spin it and recut it. Use the blade to line up the next cut. I'm in OH until Monday or you can bring it down after that.
Jon Lazar November 28, 2009 November 28, 2009 I set a rip fence parallel to the table saw blade and do multiple cuts.

davelin315 November 29, 2009 Author November 29, 2009 I think I just need to cut a smaller section of pipe. My brother held it for me while we spun it, but it was an 8' section of 6" pipe so it didn't spin smoothly. I am actually going to invest in a band saw since I do so much woodworking anyway so this should make it much easier to cut smoothly. Anyone know of a good router jig to make for this type of cut? I suppose I could spin it on there as well.
GaryL November 29, 2009 November 29, 2009 Spin it and recut it. Use the blade to line up the next cut.I'm in OH until Monday or you can bring it down after that. i do this and have no problems, but i spin it a 1/4 of the way and line up the cut with the blade then turn it on, it that makes sense. i also have a laminate blade i throw on for plastics if i can remember to put it on.
ebman74 November 30, 2009 November 30, 2009 I've been wondering the same thing. I have a 5ft piece of 12" Diameter PVC I need to cut to 32". I can not think of how to cut this perfectly. It needs to be clean so I can mount the PVC base on it. i do this and have no problems, but i spin it a 1/4 of the way and line up the cut with the blade then turn it on, it that makes sense. i also have a laminate blade i throw on for plastics if i can remember to put it on.

flowerseller November 30, 2009 November 30, 2009 What about making a table saw jig that acts as a cradle for the pipe and allows you to spin the pipe on the blade? This works great but you have to have a rip fence in place with slight pressure against it while you're cutting. I cut plexi tubes, including extruded, with a jig I made back in the day. For pvc, it's just as easy to make a couple cuts with a chop saw.
ctenophore November 30, 2009 November 30, 2009 (edited) Forgot to add, once you cut the pipe, you can use a power hand planer to even out any imperfections on the edge. This will give a good surface for bonding in the case of acrylic or PVC. I have a hand planer if you need to borrow it. Edited November 30, 2009 by ctenophore
davelin315 November 30, 2009 Author November 30, 2009 Tried to stick a piece through my planer last night and it was not very forgiving, didn't work really well with the shape of a PVC pipe on its side, gripped it unevenly and unbalanced it at the edges. With the mitre saw I always manage to get a little lip on it... I wonder if my saw is unbalanced and needs to be rebalanced. I wonder if a simple jig made with a coupling that's cut off will work. One edge is smooth and I could use my router on it with a guide. that router definitely makes a nice smooth cut!
dandy7200 December 1, 2009 December 1, 2009 I'll try and get a picture of my setup next time I'm in the shop. It is basically a stationary "sled" that sits over the blade and a adjustable over sized fence attached (14" tall since this is the larges pipe I cut). I place the tube on the sled, set the fence to the length I want, turn on saw, raise the saw blade and turn the tube. This jig cost me about $65 and a few hours to make and has easily cut over 1000pc of tube. A simple and quick version of this would be to clamp a board to your table saw fence that is at least 6.5" tall (if your cutting 6" tube), bolt a 1x2 to your miter gauge that was as long as your tube you wanted to cut and clamp it down near the blade, the use the same procedure to make the cut.
