Anyone got a good suggestion on how to perform a straight and even/centered cut down the length of a 4" diameter PVC pipe (5' long). My idea is to use the two halves as the domed shells for some DIY lighting. Gonna pop in a couple of AHSupply 55 watt kits. I have access to hand saws (no way I'd get it straight), Jig saws, Circular saws and even a miter saw, but no table saw or band saw (I figure those two would make it easy, so of course I don't have them). So... any creative ideas?

Thanks,
Blake

Hmmm, I take no responsibility for cuts, lost fingers or other appendages.....however...

Without a table saw this will be difficult, but, if you can mount the jigsaw in a clamp, take 2 2x4's or some cheap wood and make a channel to guige the pipe through, then, drill straight through the end of the pipe and through the wood to stop it from rolling, and insert a dowel or something.
Then move the pipe+channel guide over the saw blade.

Dunno how straight you can mount a jigsaw, but I can't think of any other way without a table saw.

Your suggestion is along the same lines as I was thinking, but the added idea about the dowel pin is nice. I may try that, but I will await some more creative thinkers in the mean time.

Thanks for the response though!

Trap the pipe between two upright 2x6s, snap a line down the pipe centered between the two rails, then run the circular saw down the line riding on the 2x6 rails. Flip pipe over and repeat. Smooth cuts with a file or rasp.

I tried something similar. After about 6 months the heat from the lamps baked nice brown spots on the pipe, at which point the straightness of my cuts became a secondary consideration.

If you use a circular saw make sure you use a fine tooth blade, something like a plywood blade would be good. If you don't have one take the blade off the saw and put it on backwards. I put vinyl gutters on my house and found by turning the blade around the saw moved smooth accross the gutter with no chipping.

Better Idea:

I'm not positive but I think you can buy abrasive wheels for circular saws. That would be your best bet. Less chance of the saw kicking back at you with an abrasive. wheel.

Good Luck

here is a thought on what I did once to make some gutters. I hot glued two pipes together (the hot glue popped right off afterwards). That kept them from twisting when I cut them.

Other than that, I would make some sort of rip guide since you do not have a table saw. Others may have better ideas on that.
