I love this! Many thanks for posting, and it's clear to see why those Moore machines have such legendary status. Please make another video showing the machine being reassembled, tested and in use 👌👍
Thanks for the tour of a real "tour de force" of machine building! A good friend of mine had a SIP jig borer in his basement shop, fitted, for "belt and suspenders" accuracy, with an HP interferometer measurement system. He also had a precision 1440 divider ... Ah, the delightful work of passionate people!
I am fortunate to have a 1952 Moore #2 out of Hanford plutonium production, the machine was set up by Moore for specific purpose. Still holds tolerance. Moore made vertical glass turning lathes and other special machines used at that site,, thanks for the video!
It also looks like the people using this machine took very good care of it, managed to keep the surfaces pristine, kept chips and dirt out... And, that spindle seems "appropriate" for the base!
Mr Dan Gelbart - a very smart(genious) individual who has made a limited number of videos on utube and who I think owns several private businesses making extremely innovative things (like metal 3d printers) speaks of the Moore jig borer with reverence as it achieves incredible precision and can be these days bought for scrap prices - this is a fantastic channel for precision geeks.
Many years ago, Dan had built a special "room", below ground, in his house, with a high flow air conditioning system to maintain isothermal conditions for the equipment in that room... including a jig borer. Dave Sloan (a friend of Dan and myself) had a Swiss jig borer, with an interferometer measurement system, and a Moore 1440 circular base, in his basement... A couple of precision-lovers!
If dan gelbart is to be believed its not even just cast iron but the jig boring machines made by moore are made entirely from invar. Also i want to ad, its amazing that your videos are very informative and made from true passion for the subject, no just shameless advertisements!
I was at the local scrap yard last year and they had 2 Moore #3 machines there, they wanted $1500 for each one, sadly they had been outside for sometime. Both came from LLNL.
This has awakened an old yearning to order a copy of Foundations of Mechanical Accuracy.
I loved that book. It was fascinating.

Thank you very much for this. Fascinating. And wonderful - the passion for inventing and making and using! Ah ... The Glory of it all!
What a great video to go along with Foundations of Mechanical Accuracy
As much as someone has built a good machine. It takes someone else to take care of the same machines 👍
Thanks for showing us an amazing piece of engineering and craftsmanship
I can't image that spindle having less than 100nm runout with that belt drive on there. Very interesting! Thanks for showing it!

What a piece of art.
What an incredible machine! Thank you for showing this to us! Greetings from NH!

It's from a clean room environment. Hence the clean guides.
I wish the ways on any of my machines looked that good!
Very nice video. Thanks Drew, hope to see you at ASPE in Houston next month.
It would have been very cool to have a video of how you developed the "squareness" of the spindle... Have you seen Gena Bazarko channel?

Only the head of the machine was made from invar to mitigate thermal expansion from spindle heat. The rest is cast iron

So did the machines from LLNL still have the columns or were they retrofitted with the spherical spindles?
Thank you for sharing that
Impressive!
