T, I sat at the keyboard thinking a bit about how to respond to your posts. First of all, the sander is a real work of art

. You are miles ahead of the game already as you have passion, motivation and real skill.
I believe planning is a very powerful tool. It also sounds like there is work to do to get your insurance situation sorted, and find a way to channel your skills in a way that will be helpful to others, and also provide a living.
It sounds like you would love teaching. The good news is that colleges are always looking for folks with actual skill to teach. You have a great tool that many others do not in terms of a reference..namely this thread! I have to believe there is a market for the tools you are rebuilding. If the parent company is still around, you might start with contacting them directly to see what transpires. Kijiji is free, and you already have great pics.
I might suggest sitting down and defining where you want changes. Break these down into the top two or three. Populate these 2-3 with action items, timelines, and reward yourself for hitting your goals. I'd also can consider a call to Telehealth and see what free resources they might point you to.
I'm a firm believer that the only difference between success and failure, is your attitude. These challenges always lead to personal learning and growth..and this is a good thing. Reading this entire thread, it's obvious that you have vision, the ability to execute, and a work ethic that prevails despite the pain that you are in. You are also humble enough to ask for help when you need it. These attributes make you very attractive to a prospective employer or customer if that's the direction you are looking to.
The journal here can be impersonal, but also tremendously motivating. You likely don't realize it, but your thread has inspired many...and folks have gotten off their butts after reading your posts. I'm one of them. There is great beauty in the mindfulness that results in patient craft, and excellence. It's everywhere in your shop, the projects, and your writing
