Questions on the LH Sparey Dividing head

(1/2) > >>

chucketn:
I’m working away making patterns to cast the major parts of LH Sparey’s dividing head that several people are building. My version will hopefully be used on my MicroMark 7x14 Lathe and my X2 mill.
I have no problem (yet) visualizing how it will be used on the X2, but the lathe is giving me problems. Has anyone built this DH for use on the SEIG 7x lathes? How do you use it? Can you post a picture of your setup?
My current idea is to build the DH at center height for the lathe and include 2 v-notches for the ways, at 90° to each other, and slots on each end for T-bolts for use on the mill. But then I thought if I’m going to line bore it on the lathe (first such project) I need to locate it on the cross slide. Some guidance please?
Maybe make the base as a separate bolt on?

Hi Chuck, I have the same lathe and there is not that much height to the cross slide and no T slots on mind. You would have to build it to fit where the compound slide mounts. If you do build it to fit the lathe, you would need riser blocks to make it fit your mill and accommodate our chuck also.
I don't have much else to add to help you. Oh yes, if you build it for the ways how would you make the DH move to help you cut?

Don, that's the type of discussion I'm looking for. I'm not sure what the DH will allow me to do on the lathe, that wouldn't be easier to do on the mill anyway.
I had thought about riser blocks for the mill.  Also thinking of getting the mill table from the 3-in-one style SEIG machine and adapting it to the lathe fpr line boring, milling, etc.

Chuck another way is to make a new cross slide and put T-slots in it, but they would have to be 1/4". My be able to make them 5/16". Do you plan on doing some milling on the lathe?

Don

chucketn:
No, not a lot of milling as I have an X2, but it would be nice to have that capability. I would like to line bore cylinders though.
