"shop smith" , from 1970's . 6x48 cloth backed alox, but not coated like modern stuff. the detail i now remember is that most old belts were directional, and...- tnmgcarbide

Aluminum sticking to table saw balde?
your cutting speed for a 10" 1700rpm saw would be around 1600-1800 sfm? that would be ok w/ coolant . if you could lower your dry blade speed to maybe 1000, with a vfd ? it might also create chatter and make a new problem. nothing is ever easy .- tnmgcarbide

Enco 111-1445 Lathe in Powell, TN. $7900
"An Enco is likely a low end rebranded Chinese machine, brand new similar quality and sized lathes go for around $6k with some tooling. " i disagree . a new chinese Acra would be 10x the machine . Enco machinery was the worst of the worst . they were sort of Jet lookalikes at the time , but...- tnmgcarbide

Windpowered 16mm Camera Help
"At slow speeds the shutter will pass slowly over each frame, and the film will be washed out. At high speeds the shutter will rotate quickly, and the film will be underexposed. I don't think this camera will be able to maintain a consistent exposure with a variable speed external drive." i...- tnmgcarbide

Super glue not drying
There's no trick and I'm sure you understand you have to get the proportions right they can go either way. But for a 1980s game changer this was fantastic. Super glue had just become a big deal in the late '970s but when you could add filler to make it like an epoxy and freeze up solid it was...- tnmgcarbide

Super glue not drying
i disagree, c-a is not a-e . pour some on your fingers and tell me how a-e it is . on your skin, it activates by moisture. none i know made from loc-tite or super glue are different . pour an 1/2 ounce of c-a onto 1/4 cup of baking soda ... i predict it will be a stone in less than 2...- tnmgcarbide

Drilling hole in hard steel: Speeds? Feed? Lube?
if you are drilling a 1/4 hole in "hard" steel , say 45rc ? with a "drillpress" i think you'd be better off not wasting a fragile, expensive drill . those work great in a milling machine, but not good in a drillpress. a drill chuck is seldom capable of better than .003 TIR, and a carbide...- tnmgcarbide
