On the bolts that held the bed assembly to the frame I ended up using a 3 inch grinding wheel- It cut into the old rotted wood and the thick washer, but the bolts were rusted stuck and the carriage part had nothing to bit into- I have thought about upgrading that part of the design so that It is easier to remove the bed, and so I do not have to rely on the wood as the "vise" for holding the carriage end of the bolt in place. I have not touched the bolts that hold the metal retaining strip yet(for replacing the wood- But I have purchased a new complete bed bolt set that is stainless- That way With some anti-seize I should not have to worry about being able to get the bed apart.
