Exactly. "Quick change" isn't quick if it's not repeatable....

I didn't know it when I built mine, but it looks similar to Hardinge. I based the dovetail clamp on John Stevenson's design. The body indexes at 15°...

Chris, it just occurred to me, something I've done for a temporary reference mark is the good ol' sharpie. Wipe it off to re-set.

[Randy]

Is your lathe SBL 9A not like this? (I know it says metric, but inch would be the same.) Maybe the dial is stuck on the screw shaft? Even if you had to...

Excellent work.

Where I worked we used them to do a four-hole pattern in aluminum about 1/8" thick. I think we used a multispindle machine and did them in one shot....

Just as Rich and Dan mention, I wear an apron and use my 6" flexible rule for tool height setting. Have for decades. That is, until I recently saw...

+1 on what Rich C wrote. I just happened to watch Robin Renzetti's video on precision spindles. He covers this in the first few minutes.

I made one for my BP copy out of UHMW, a few magnets, and an LED "halo" for dressing up car headlights. Many sizes avalable. I don't really...

Decades ago I built a 4-way tool post to replace the rocker style. I based it on a catalog photo of a Royal 4-way, which indexes at 30° increments. Repeatable...

Years ago I got a nice little 100mm German made chuck really cheap from an MSC clearance flyer. Careful as I was making a back plate it didn't run true....

[Randy]

I stayed up until 5 AM (west coast) watching the coverage. (I'm a night owl anyway.) I think I was more excited for this launch than any since the Apollo...
