Three methods I've tried for Cutting PVC.
PVC Ratchet Cutter
Hack Saw/Miter Saw.
And Miter saw with a metal cutoff blade.
A cool site where I got the free plans for the end table.
This was a fun project, took a few hours. But without evenly cut pipes that were exactly the right length it would have been a nightmare.
Step 1: PVC Ratchet Cutter
Great for taking a 10' section at the store and cutting it down to fit into your car. OR fixing pipe on the fly away from the shop.
BUT, they do not cut a straight 90 degree cutoff.
If you are building a project that is creating rectangles and squares, or if you want it to hold together really well with cement. You need the squared off cut.
The other problem is having several pieces exactly the same length. I was using the method below. But it is still off by about 1/64 to 1/32 of an inch. A. you have to use the same sample measuring piece each time, or after 8 pieces you could be 1/4 inch off.
