Dividing Attachment for Mini Lathe

[old_toolmaker]

I built this dividing attachment to fit my 7 X 16 mini lathe due to a project I had involving the engraving and stamping of micrometer dials and 360 degree angular setting dials for the cutter grinder I built. I have used it for other projects since such as engraving the lines on other micrometer dials, drilling holes in dividing plates, gear cutting and cutting splines in a shaft. It has come in very handy and I don't know how I ever got along without it.

Hi Dick
I have a similar set up on my SB lathe giving 60:1 ratio

It is nowhere near as nicely made as yours but I would not be without it. BTW what ratio are you using.

olderdan,

Thank you for the nice complement!
The ratio I am using is 45:1 due to the fact that I am driving the standard 45 tooth spindle gear with the 8 pitch worm. I know this somewhat limits the number of possible divisions I can make, but it does everything I have needed so far. Also I could use different spindle gear if I need to divide something other than what I can do now.

Hello,

Your fixture looks very nice, and quite easy to machine !

Please could you provide an additional picture showing how the fixture is mounted on the lathe ? May be on the spindle ?

Good built, excellent job.

yves78,

I have uploaded additional photos for clarity showing the dividing attachment mounted on the mini lathe. I have added them to my original post. What may not be real clear is that the dividing attachment is mounted in a skewed position in an attempt to match the helix angle of the worm to the idler gear.
