I'll be happy if you find something that can extend the life of these machines. I just want success for people's endeavors here, nothing owed lol.
Engineering used to be about problem solving, figuring it out. Like doing a crossword puzzle. You never worried, just kept chipping away and learning. Some searching, the right keywords and I can somewhat understand the machine enough to help a bit. Physics, MecE, EE (multidiscipline) knowledge needed for this Tempo make it difficult.
Today, young engineers literally have a panic attack if they don't know something. There seems to be a stigma with "not knowing", even in business and management. I find it funny, being free of such worry. Electronics gives a constant humiliation for those types of people, the "know it all" types especially.
If you don't know enough, then ask - I've learned to reach out to manufacturers and sometimes they have great expertise.
I am so frigging tired of people who WANT to fail. So I passed on your post to both of the service businesses; the one responded saying emphatically that you cannot buy donuts! Have not heard back from the person who actually bought all of L&Rs inventory. He is likely much more confident.
That is what people told me before I had all the breakable parts for the Hamiltn M21 made and 100s of mainsprings for my bread and butter aircraft clocks. Paid those back 5 times over in the last 30 years.
Most people are too damned timid to seize an opportunity. They say "no" when a life altering adventure is right in front of them. In all my years, I have encountered very few ventures or adventures where saying "yes" resulted in my death. Most of my regrets involve saying "no".
Fortune favors the bold. While the meek may inherit the earth, nothing was said about the timid!
