12x36 Lathe Taper Attachment

It's together and it works!

In the end the only mod I made was boring out the saddle + ordering the 13 tooth gear. And the feed screw nut needs to be drilled and tapped wherever it falls on your machine. I assembled everything and transfer punched it - works fine without any tight spots.

I haven't turned a taper yet need to do some final finishing but I can't see any reason why it would be junk. Will report back when I find out.

The only thing stopping you from turning very long steep tapers can be seen in the last photo attached - when set beyond 5 degrees the gib screw adjustment in the housing will hit the casting. I have not investigated to see if this is backwards or otherwise could be relieved - will cross that bridge one day when I unlikely will need to make a long steep taper.

Couple more things ... my backsplash will need to be modified and moved back a good 4 or 5 inches if I want to continue using it.

The extra casting that is included would be for running this telescoping lead screw if you removed the taper attachment.

And I now have an extra hole in my cross slide because this machine came with a pair of split feed screw nuts and backlash was taken up using the central screw hole and a gib like piece that put pressure onto the two nuts. I'll turn up something for the large extra hole so that I can easily get lubricant onto the feed screw.
