To joint long pieces of material, tune in to J-channel
I needed to put a straight edge on a long piece of stock, but because the piece was longer than my jointer's tables, I didn't have much luck. I headed to the hardware store and bought an 8' length of aluminum J-channel (normally used with aluminum siding).
I sawed off the flange, as shown, and attached the J-channel to my board with cloth-backed double-faced tape. Keeping the channel against my tablesaw's rip fence, I then cut a straight edge on the opposite edge of the stock.
With this one 8' piece of J-channel, I've found that I can joint stock up to 10' long. The tape will keep its tack for many boards if you wipe the dust from the wood before applying the channel.
