From February, 2010:
What I wrote about this part then:
This is part of a drawbar for my Steinel horizontal mill. I decided to make it in two pieces - a 3/8" rod, threaded on one end, which slips into a cap that was turned from 1" rod. This is that cap. It took a few steps to make - little while in the lathe, a few minutes in the mill, little while back in the lathe. It's not quite finished - I gotta TIG the two parts together tomorrow - but jeez, I'm finally close to getting this machine set up.
