I hope your shoulder heals well. In your thanks reply you state that you used to help out at a machine shop. I would ask them to drill the holes and it would probably be free. If the wing is too heavy, ask a friend or relative to help you for all 5 minutes to hold the wing while you bolt it. With the wing in place you won't be concerned about storing it and your saw will have a nice big surface. I worked as a sales rep for a machine shop about 9 years ago and still have an excellent relationship with them. I left on good terms. If you still decide to store it, do NOT use the shipping paper they use. This is for short term use only, and can collect humidity as the oil in it evaporates. I have been selling chemicals to the metal working industry for a little over 2 years now and I know we sell rust inhibitors in Ontario and Quebec and only in industrial quantities, but I'm sure the auto parts stores or welding supply stores will have something to offer you for extended periods.
Don't fear your tools, pay attention and respect the tools and avoid injury.
