Once I get the threads started, I never take it out of gear. I let it run back a way to check the threads. If I'm using the tail stock, just slide it back. Saves me a lot of rework.
Brazing came off better than I expected. Found a slit saw in my stash for the first cut. If not for the 5⁰ angle it would be easier. But that's why we are called machinist.
My skiis certainly aren't what they use to be, but I can do it. If I braze it I'll probably recut on the Bridgeport. My machining skills are better than my welding skills.
I might braze the bad teeth if I can't get something to make another one. I really need to get the lathe going. My Atlas isn't as hefty as th Grizzly. The gear an shaft are not available.
I took mine at 62 then worked part time. Was doing pretty well until my wife got ovarian cancer the second time. I had to quit and stay home to take care of her. When she passed in December 2015 the shop was closing. I still worked at home a little but the income was half.
I had to deal with that cognitive stuff after I broke my brain August 2021 in my motorcycle wreck. My wife broken leg and I couldn't drive for 6 months. Home health care and my kids kept us from killing each other. Lol
