Which leads to the ultimate unaswered question, what did they use to make the first lathe or mill? Well of course there are answers but I rather not know & forever wonder.
Interesting idea isn’t it?
If you’re interested I read a fascinating book called “Island of the Lost”.
It’s based on true events of two ships that wreck on Auckland Island. The crews have completely different experiences. One crew flourishes while the other struggles.
The one that flourishes built a forge
Highly recommended reading!

With my tight space I thought it would be good to buy leveling casters so I can move the Bolton 13x40 back and forth from the wall. I ordered these from Toolots, the Bolton dealer, 4 of them for $64.

I needed a larger caliper to compliment my 6" HF and 8" Mitutoyo caliper. My 6" HF caliper is used the most and is starting to show some wear. Still seems accurate and can't beat the under $20 price. The jaws are loosening a bit.
Then, there's my 8" Mitutoyo which is kept in the box except when needed. Silky smooth and a joy to use. I wish it had an auto shutoff.
So, I struggled when deciding with which 12" caliper to go with. I looked at Starrett, Mitutoyo, Fowler, SPI, B&S, etc. Prices were crazy. After reading many positive things about Shars, I decided to go for it. It is REALLY nice and smooth, seems very accurate, and well worth the under $80 price. I'm not sure how it will stand up over time, but I'm very pleased so far. I might even replace my HF 6" caliper with a Shars when it dies.
It's my favorite chuck... it takes some figuring to center a part with 3 adjustable jaws the first few times you use it, but once you get used to it, it is quick and easy. I can get a part centered within a half thousandth in less than a minute now. I really like it... it's a lot easier than a 4 jaw.
Bear, I’m curious as to your method. I’ve given it some thought and in my mid.... I’m thinking that the way to go about centering with 3 jaws.... is with dial indicator mounted....to focus attention only on the low point. And then adjust that jaw since the high points will always be midway between the other two jaws. Does that make sense. Am I on the right track ?
Anyway I’m not there yet since I can’t mount the chuck to my other find.... Bison Backing Plate... for 8” chuck and with a L-00 taper. I need to go to hardware for 7/16”x14tpi socket head bolts.
Anyway...between the Rohm chuck and Bison backing plate.... I feel like I have a horse shoe up my butt, finding this and the chuck on EBay at the same time. The backing plate was “ accepting Offers. “
got it for 115.00 plus 21.00 shipping.
