So does anyone know where the Camlock Spindle assembly is available?

Can you provide details of what lathe you have so others can note it. I
have a D1-4 Camlock on my Harrison M300 and all indications are that
the spindle is one piece, the camlock assembly being integral with the
spindle.

At least on D1-size there are really two camlock components. The
spindle has a number of radial holes that intersect the axial holes that
accept the camloc pins. This is all in a ring that is usually one solid
piece with the spindle taper. (The other piece is essentially part of
the chuck, and had the camloc pins threaded into it.)

I think you are referring to the spindle side of things. Since the
camlock face of the spindle is a precision part of the whole assembly,
and needs to have a very accurate relationship to the external taper of
the spindle, they are made as one piece. The camloc adaptor that is
part of the chuck is supposed to BOTH fit flush to the spindle face AND
seat on the external spindle taper, to a high degree of contact. I have
never even figured out how the heck they do that to any level of
precision, but it obviously is a very critical machining task!

The spindles are frequently cast and then machined to size.

I've never seen the separate piece design, but my guess is it was
assembled first, before the spindle was machined, and is designed to
never be separated.

I have a Birmingham lathe. 13" X 40". There appears to be a brass
sleeve that separates the spindle proper from the camlock assembly. I
have not opened up or removed the spindle to confirm this. Another
reply suggests that the whole spindle assembly, camlock and all starts
life as a casting and lots of maching from there.

I would like to have a camlock assembly, spindle side of things, that
I could thread to fit a LeBlond lathe that has threads. I don't
understand that this would be difficult, if it would be.

Thanks for the response.

Yes I am referring to the spindle side of things.

I was hoping to obtain a camlock assembly, mount it to another camlock
assembly, center/true as necessary and thread it to fit the lathe in
question. A LeBlond lathe in this case. Not a job for the novice but
certainly within the capability of many.

I think you'll find manufacturers lay claim to machining their
spindles from forgings.

From previous threads on Birmingham lathes they are chinese so how they
make them may be different from how US and UK makers do their camlock
spindle. One point in doing your threading method will be, I expect, you
won't get the accuracy desired for the mount trueness so a clean up of
the camlock face and taper would be needed which will require a toolpost
grinder in all likelihood. The other problem which was brought up
recently on another thread is that increasing the extension of the chuck
is not beneficial to the rigidity and can increase the likelihood of
chatter.

Yes, Tom, that is what I really MEANT to say! Thanks for the
correction.

I know this is an old thread but I have a metric buttload of really expensive beautiful chucks all with the d1-4 camlock backplates....

I have a couple of smaller lathes but want to build a large one. I would like to incorporate the camlock into the spindle and was wondering if anyone ever got anywhere with this?
ALSO, another use I have considered is having a camlock spindle nose to mount to a rotary table because that would be awesome for changing out chucks...

I recently adapted an eight inch manual chuck to my CNC lathe. This
CNC lathe has an A type spindle nose so I used a faceplate and bolted
the manual chuck to it. However, I considered putting the camlock
features in the faceplate and would have done so but for the 4 T slots
already machined into the faceplate. There is plenty of info online
and producing your own would not be hard to do. For someone who can
build a larger lathe the spindle nose machining should be no problem.
Machining the taper is easy and I have repaired a couple chucks over
the years that had badly damaged tapers, as well as made adapters that
fit various machine spindle tapers. Camlocks are simple, imprecise,
and easy to produce mechanisms that locate a device on a taper very
accurately which is why they are so common.
