Maybe a tad towards the high side, but I'd say that was just about right.  It's not seeing a lot of impact/shock type force, so it should hold up quite well.

Thanks for sharing your set-up.

Both good point guys, thanks.

I don't know.... you haven't seen me hanging from the bar and bouncing up and down trying to free a bearing from a motor armature.

The more I think about it, the more I want to go ahead and do a second tempering and bring the hardness down some more. The areas around the keyway corners are pretty thin.

Today I swapped the 240v single-phase in, 240v 3-phase out VFD on my lathe for a 415v 3phase in, 415v 3-phase out model. It was only a few months ago that I cottoned on to the fact that I was running a 415v 3-phase motor on a 240v 3-phase supply, which explained why it would not run up to speed in top gear, and why it slowed down with heavy cuts. Since I now have 415v 3-phase available via my rotary phase converter, I decided to feed the lathe the volts it requires, spotted an appropriate VFD on eBay for a reasonable price and it has been sitting in the shed for a couple of months. I ran out of time tonight before I could chuck anything up and make some thick chips, but the lathe now runs up to full speed without difficulty. As an added bonus, I discovered that the chart on the gearbox is not quite correct, all the other gears clock exactly as charted including 4th with 700rpm in high, but what is marked as 3rd (of 4) gears with 400rpm actually gives me a tad over 1100rpm in high range. Happy days.

Good to hear Pete.

The staircase wouldn't fit into the basement assembled so today Charlie gave me a hand to put it together on location, instal is scheduled for tomorrow.
He set up a camera and did a 30 second per shot time lapse.
Wish I could actually work that fast.

Greg with the amount of progress you seem to make on a multitude of projects, I thought that was how things must look in your shop on a normal day.

I assumed the vision was played back at slow speed...
