Here’s one for the wood gurus. I have a 12’ x 6’’ x 3/4’’ cedar stringer for use in a surf/paddle combo. It is slightly bowed from end to end–it jogs out maybe an inch over the twelve foot length. I am using 1lb eps and doubt the foam will be rigid enough to have a straighting effect when glued up. Any thoughts on straightening this sucker? The stringer was jig sawed from a cedar siding plank and the grain appears to run down its length. It is currenly being weighted down on my garage floor with cinder blocks ‘hicksy style’.
Steam the bent section (just over a pot on the stove, coverred with some towels) for 30 minutes minimum per 1/2 inch in diameter. Then bend it back (by hand or jig assisted) to about one inch past the original bend. Now hold it like that while it cools. That’s maybe five minutes per 1/2" dia.
As you can see some kind of jig and gloves are going to be handy.
That’ll fix and can be repeated as needed.
Cause? You probably have some grain runoff (it’s not always visible to the unassisted naked eye) and it probably isn’t sealed as well as you think.

hi try this
soak for a few hours in water
than iron it dry abd flat on a board with a hot iron
drill a hole in the end and hang it up inside the house
so it drys evenly on both sides
