Lathe Chuck Key

• Using the non ball screw milling machine to take heavy cuts. .3doc, full width .75

• Torch bending and heat treating

• Connections to matsci class regarding the FE-C binary phase diagram and the composition of the 1045 steel

• Attempting to do some hot-stamping rather unsuccessfully.

The shop bought two new smaller lathes, and I have been the main person setting them up to be run. This has included leveling, installing tool posts and setting up tools, adjusting the chucks, ect. Over the course of doing this however, I have been very annoyed by the crappy chuck wrench they provided, it is just a piece of square bar bent 90 degrees. They didn't even take the time to de-burr so the corners are sharp an painful to grab onto. I took the opportunity to make a new one copying the design from the bigger lathes. It was a pretty straightforward operation, milling the square end, by indexing with a collect block, then taking off the sharp corners on the lathe and adding chamfers before bending and heat treating the handle. I thought a bit about adding a finish to the surface such as blueing or maybe powder coating, but I think the oxide layer from the tempering will be adequate corrosion protection and I can always sandblast later on.
