I had a slight warp to some of my forms. I didn't worry about the regular forms. I tried to correct the rear end form but it wasn't enough. Luckily, I noticed after a few strips that the stern was going to be twisted. I built a triangular frame around the end of the boat and tied it in place. Now that I'm almost done stripping, I see that it's perfectly straight but it would have been easier to recut that form out of better material in the first place.
