Does anyone have any recommendations for squaring up the edges on old wood? I’m trying to cut the bad edges off of some barn lumber, but both sides of the board are irregular. I’ve thought about using a circular saw on one edge with a guide…

It depends on how bad a shape the board is in. I usually just put the best edge against the fence, and rip off as much as I have to in order to get a clean edge on the other side, then I flip it over and do the same to the other edge.

Sometimes these jointer clamps come in handy.

I do the same as Charlie. I try to use the TS to do most of it, then finish it up with the jointer.

Make yourself an edge straightener for the table saw. Take a piece of plywood or PB or MDF thats straight and 8” wide or so and as long or a bit longer than these pieces of old wood. Attach a cleat along one edge about 1” wide. Put this on top of the board you want to straighten, cleat side down, with the concave edge of the old board up against the cleat. Use the straight edge of the ply and cleat against the fence to straighten the first edge.
Then do the other edge without the “jig”. You can even tack the thing to the face of the board if necessary.

I second Michael Murphy, I nail a straight piece right into the side of the board, it’s the fastest. But if it’s a good piece of wood, I draw a line and bandsaw it, then run it across the jointer a couple times. If you rough saw it to length first, you tend to get more out of each board.

A tapering sled works well for this.

Here’s what I mean:
board and jig before
unfortunately it’s a ten foot board and 8 foot long jig but it will work.
jig on board
Running it through the saw.
straightening with jig
Here’s the end of the straightening jig.
board and jug end
These simple jigs work great. Whenever I bought lumber in Random Widths S2S, (RWRLS2S)when the load came into the shop we would straighten the boards, then store them or rip into face frames or doors or whatever. I had them in 8’, 10’, 12’ lengths.

I think this idea came from a Popular Mechanics article from a long time ago. They were using an aluminum angle “Iron” with a hook on the end to push against, but shorter lengths.
