If you need to cut a bunch of cardboard concrete forms, you could use your tape measure to make a bunch of marks and try to follow your line with your saw, but there’s a better way.
Rick Tyrell of Prosperity, S.C., made a jig to get accurate and straight cuts on his cardboard concrete forms. Here’s how he did it. Start by cutting a small portion of the cardboard tube off from the factory edge. Then, he rigs-up this cutoff with a hose clamp so that it will fit over the tubes that need to be cut. Then he secures the jig in place to make a crisp and straight layout line. To take the jig one step further, he uses the jig as a guide for the circular saw to make a straight cut all the way around.

Awesome!
I am getting ready to have to do this to put in new fencing. Could one use a table saw and skip all of this?
Great tip! But even better--I love the dog! Maybe he can 'help' you with some additional tips!!
Hey Synchrophoto, you probably could cut these tubes safely on a table saw. Set the fence as far from the blade as the amount you need to remove from the tube. Raise the blade maybe 1/4 in. - 1/2 in. And clamp a secondary fence to the table, perpendicular to the main table-saw fence, against which to register the tube. Go slow. Be careful. If you come up with a clever set up that works well, let us know. Maybe we can feature it here.
