Manufacturing Definition and 102 Threads

For as long as I can remember, mechanical manufacturing has held a special place in my heart. Growing up, I was captivated by machines—their precision, their power, and the way they transform raw materials into complex products. This fascination wasn’t just a fleeting interest; it was a...

I know there are no perfect things when it comes to manufacturing. And when precision is required, the smallest defect can be unacceptable. I was watching this video about setting a mill up to spec and the author mentioned that dowel pins are not truly rounded so they shouldn't be treated as...
