Hello Andrew, and Welcome.
If anyone can come forward with an engine hoist (Folding crane ) and some strong enough slings, with a little help it should be possible to load the machines into a van or pick up truck (sheet and tie down and wedge for the journey ). Boxes of spares / material etc can be used as dunnage to reduce the risk of movement. Ratchet straps can be invaluable for this sort of work
Even without lockdown, I am too far away, and my crane will not fit into my downsized car, to be able come and help. So can only make hopefully helpful noises from afar.
A lathe like a Myford ML7 can be lifted and moved by two men,although the offset motor makes it a little unwieldy.
A milling machine will, need more care, and may well demand the use of a crane.
Whatever you are moving, you will know the need to take care not to injure yourselves or the machinery.
A lathe can balance better by positioning the Tailstock and saddle along the bed.
A Mill is best moved with the the sling around the head, so that the centre of gravity is below the slinging point.
No doubt there will be plenty of round bar available that can be used as rollers to move a mill along the floor. A lathe is best placed on a sturdy platform to moved in similar fashion.
If yiu sling bthe lathe,take care not to crush leadscrew or any other shaft. It may be frowned upon by many but sometimes a sling behind the chuck and Tailstock end of the bed is a safe way to lift it.
When you get set up, making the 10V will give you the experience, skill, and confidence to start work on completing the Triple. That would be a splendid memorial to your Great Uncle!
Good luck with the move and setting up your shop.
Howard
