Colchester Bantam Adjustable foot thead?

I need to know what the Colchester Bantam (MK1) Adjustable foot thead is?

[Deleted AccountParticipant @deletedaccount69088]

I was wondering if anybody knows for certain what the Colchester Bantam 1600 MK1 Adjustable foot thead is? the manual says 1" UNF but that's clearly wrong. The foot is full of mud and will need cleaning out so I want to be sure I've got the right tap – cant find the original feet at the moment to check with unfortunalety. Thanks

PS also are all three threaded?

Strange because my Bantam mk1 800 I'm sure has the same stand and the adjustable foot does have a 1"UNF adjuster. The other 3 'feet' aren't threaded as the hole in them is just for bolting down the stand to the floor. I don't think the stand was supplied with any feet to go in the three fixed lugs/feet.

Ah that explains it The other three are just approximately 1/2" holes then. The thing is I'm sure I have 4 rubber pad bolt things that came with the machine somewhere. Perhaps they don't all 4 adjust.

I have a bantam Mk1 800, the threaded foot is just to adjustment to stop it rocking on the floor, you can bolt it too the floor, but it is quite happy with no bolts, it is not going to go anywhere.

I have mine on some old paving flags to get a bit more height, as it is a bit low for me.

yes I see that only one needs to be adjustable for it to level as the other three are like a tripod. I thought they were all threaded and adjustable to level the lathe my mistake!

Seems a bit odd to me. Certainly it can be stable on three feet (i.e all three will touch the floor) but not necessarily level. And I don't think you can then level it by adjusting a fourth foot …. although you might make it rock.

Quite sensibly they have recognised that the critical requirement is to avoid twist in the bed – by providing a means to equalise up the loads on the 2 tailstock end feet. Whether or not the bed is dead level in the headstock to tailstock direction is of absolutely no consequence whatsoever unless you want to do some willy waving down the pub. These machines were designed for installation on a reasonably flat slab.

My Bantam now has 4 resilient (rubber) feet. They didn't cost much but provide full adjustment on all 4 legs and can cater for the (in some places) ridiculous unevenness of the concrete floor in a typical domestic garage, compounded by the slope normally found there. Evening up the loads on the front and back feet is surely the simple approach to avoiding distortion in the bed.
