With some time off this upcoming holiday, I would like to try my hand at turning a one piece crank. I'd like to try one from shaft stock as well as flat stock. So what kind of tips, tricks, and pointers can you pro's out there lend my way?
Bigger? Holy moly, they're plenty big in Firefox on my Mac laptop. What details are you trying to see? Any bigger, and you'll start seeing burrs and tool marks, and think my work is crappier than it is.Vernon said:Neat photos! I wish they were bigger.
You're right, you have to like cutting temporary threads and then turning them into swarf. Fortunately, I'm mental and really like single-point threading, and I'm pretty fast at it. It's a lot easier with the lathes I have compared to something like a 7x12, AA109, or Sherline. I could have tried turning the final main shaft, journal diameters, and threads when I machined the original slugs, and made the fixture to fit the final sizes accordingly, but I was afraid the steel would move around on me as I cut the throws and webs. The 1144 material is supposed to be stress relieved to minimize residual stresses, but it's not perfect.bearcar1 said:I'm not too keen on the one end threaded routine but I need to digest ore of this jigs potential.
