I went to a local industrial sewing machine repair shop, here in Las Vegas, and talked to them about my needs and wants. I ended up buying a refurbished JUKI, I think the model is a 538. I had him install a servo motor. They are going to show me how to maintain and use this machine. They also carry all the parts and accessories I might need, like extra bobbins, specialty feet, oil etc. Now I just have to figure out how much my labor is worth when I give an quote on a job. I already have 2 people who want me to look at their boats. In Nevada the sun will eat a boats interior if its not covered, so there is always a source of boats that need work. Wish me luck in my new undertaking.
