I'm thinking seriously about putting Thomas Morrison's taper attachment from
the October/November "Machinist's Workshop" on my to do list . His design is
for a Grizzley which seems to have a flat crossfeed carriage surface and tee
slots. My Logan has a curved, unslotted, unholed surface on the back side of
the crossfeed. The only soluton that comes to mind is to mill a flat on the
crossfeed carriage and drill and tap a couple of holes. Is there a better or
more elegant way? How are Logan factory taper attachments mounted ( assuming
they are of similar design )

any comments are welcome.

What model of Logan lathe do you have?

Sorry, I guess I figured that if I knew what it looked like everybody else
would too :-). Its's a model 201, 10" swing over the ways.

Here is a picture of one from the logan website. I'm not exactly suure how it
attaches, but it looks like you need to remove or disengage the crossfeed
leadscrew.

Scott Logan is such a nice, helpful fellow that he might just tell you if
you asked him...

For the taper attatchment, the lead screw is splined/keyed to
the shaft on the handwheel.

The leadscrew can slide in and out relative to the handwheel.
The thrust bearing for the leadscrew is on the taper attatchment.

As long as the taper attatchment is not moving, it acts normally.
