Turning a new steering stem

Here is a vid of turning a steering stem, I like the way he sets it up to bore the thru hole. Sometimes they will drift off center but this nails it.

I enjoyed that video , thanks for sharing it. I wonder if that 1144 steel can be hardened?  Would love to have a DRO on my lathe someday, sure seems like a big time saver.

Informative video, thanks for posting.
I bought a Chinese 2 axis DRO for my 12 x 36 lathe and a 3 axis for my mill, $400 ~ $500 per machine, made a huge difference for a hack like me plus no more backlash to worry about for picking up a position.

Original stem had a step in the bottom diameter so it would be a pressure fit in the bottom clamp and still be a gage fit in the bearing. He hit the step with the ring gage at the end of video and blamed the hang on shaft damage.

The stem he turned was a straight diameter to the shoulder. It will fit the bearings well but be too loose in the bottom triple tree clamp.

Yeah, I noticed that too. I thought he would be making another one and wondered if he was going to film it.Otherwise it turned out fine but that would make it unusable for me.I thought the major thread diameter was a little small as well. I’ve made three to get one good one on a V65 when I needed a longer one for the conversion from ball bearings to tapered bearings
