Camlock Spindle Assembly again

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.

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. Jon |

The Camlock Spindle Nose Assembly has the camlock part mounted on or
secured to the spindle. On my lathe it appears to be a separate piece that is either pressed on or thread mounted and then secured somehow. Probably not welded.

Camlock Spindle Assembly again
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.- Hide quoted text - - Show quoted text - David 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. Bob AZ |

Jon 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. Bob AZ |

Thanks for the response. Bob AZ 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. |

Thanks Bob AZ 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... |
