My condolences , I lost my father about 20 years ago and I still miss him. I too have all his woodworking tools and mechanics tools, I would say if your not going to use them for a long stretch I think you should give them a good coating of grease on all bare metals then I'd lay wax paper on top then use a tarp even indoors it will help protect from condensation rust . I've done that to cast iron table saws and they clean up nice with no bad rust or discolor of the metal. Remember rust loves to eat .
