How To Make a Woodworking Spring Clamp out of PVC Drainpipe

If you're building a solid-surface countertop with a thickened edge, you could buy a bunch of spring clamps to glue that edging on, but there's a better way.
Jim Chestnut from Miami, Florida, discovered that you can make very servicable spring clamps from 3-in. PVC drainpipe. He cuts the pipe into rings on the chop saw, and then he makes kerfs in the rings using a bandsaw or hack saw (don't use a tables saw!). Now you can spread them apart and clamp a whole length of countertop edging. A half dozen clamps costs less than a dollar.
Watch the video above to get more details on how to make and use these homemade clamps.

Yes, I think a jigsaw could work, and it wouldn't pose the table saw kickback problem. Give it a try and let us know how it works. Thanks for the feedback.

DON'T use a table saw to cut a lengthwise kerf in a piece of PVC pipe. The pipe will act as a clamp on the blade, and you'll run the risk of a big-time kickback.

yes, the wider the pipe cutoff, the more the clamping pressure

Especially when you claim you stretched the board an additional 12 inches.
Come on guys whats the deal.

Do you increase the clamping pressure by cutting the pipe slices WIDER, and decrease the pressure by cutting THINNER slices? Or did I miss something?
Thanks.

If you drive screws in at an angle to the clamp kerf/opening, you can use the clamps as miter clamps.
And you can use foam-core PVC, ABS and HDPE pipes to make clamps too.
Recently I made some 2 in. wide clamps to hold plastic sheets on a greenhouse frame.
I'm always scrounging through the plumbers' waste pile for more clamp stock.
