Colchester Student Rear Toolpost help needed

[754]

On my turret lathe i kept parting tool on front of cross slide. On the rear i mounted bevelling or radius end tools mostly. It had stops for rear tool infeed depth, very handy .. worth building in if you can.

On mine I have T slots on the bottom block perpendicular to the spindle so I can move it out of the way for turning. My top slide has t slots running parallel to the spindle

Hmmmm.... my text disappeared......

Basically, it was mentioning to watch out for the "double negative" that puts you back where you started.... reverse how many things?

Upsy down on back is exactly the same topologically as right side up on front, and cuts the same thread for the same carriage movement. (and vise-versa).
