Update: My year-old metal lathe died about ten days ago. While still under warranty, it would have taken months to get it repaired and returned, so I just bought a new one using plastic. It was a circuit board that failed and they won't sell me the entire board to swap-out. Not being an electronics engineer, it would have taken me weeks to months to track-down the offending component, although I have my suspicions based on experience. Solid-state physics classes were 35 years ago, lol! I sure do miss the old days of non-electronically-controlled machine tools. They were far better and more robust. And made in the USA. The new ones are not. Grumble. I'm currently cleaning the cosmoline off the ways of the new lathe, and hope to be back in business in the next day or two. The design is finalized and production parts have started to stack-up on the assembly table. I have a working prototype and it's pretty cool. Stay tuned!
