The Russians used 240mm cables, but electromagnets were also used to degausse ships.

Oldsalt1950's post in WOOD SHRINKAGE! was marked as the answer
You have just discovered the hydroscopic properties of wood. The Isopropyl removed what moisture it could from the wood = shrinkage. Water bath, rehydrated = swelling. The wood needs more moisture. Think of it like a boat, out of water the hull dries out a bit and some seams will if not properly calked open up. Put the boat back in the water and the seams leak until they swell up. If not enough water can be absorbed by the wood, you keep bailing the boat out. Thus, ends today's physical science lecture this information is testable!!!!
