revisit A1-4 Spindle nose

Swarfing:
After a long period of messing about trying different things, i'm going to attempt to make a D1-4 nose to fit over the existing. As some of you may remember from threads a while back i had been having problems obtaining appropriate chucks at reasonable prices. I've managed so far with adapter plates which work fine, just a real PITA when i want to switch. Long term this is not acceptable and i am fed up loosing my knuckles undoing so many cap head bolts each time.

Does anybody have any details/ dimensions (camlock holes, screw holes, position around circumference etc) of a D1-4 nose? plenty of info on web i know but i would like to make this to a known standard. Would like to keep it metric so any help would be grateful. An alternative is to re-machine the nose end of an existing D1-4 spindle to mount over my A1-4, so if anybody has an old spindle they care to sell then would be very interested.

Thanks

Paul

For those interested in what the existing nose looks like a pic.

The D1-? spindle is an American design and all of the dimensions are imperial. This site can provide those dimensions.

Back in 2009 one of the members, "DeereGuy", posted a build log detailing how he made a D1-4 receiver from aluminum. Here's the link.

Hope this is helpful and good luck with the project.

Hi Joe i would like to say that is true but they do come in metric versions too.

British & I.S.O.. Standard Spindle Noses, Mine is the A1-4 and the d1-4 follows the exact same dimensions for the spigot.
Check here.

There are also German DIN standards

Not a lot in the difference but there are differences. My lathe is French and follows the British standard where the outside is only 108mm.

75Plus:
No matter where the spindle is made the dimensions, imperial or metric, must match the original design else it would not be a universally supplied spindle. I found this page on Tony's site that notes both imperial and metric dimensions. (Bottom pic)
