Rotate the compound 180º so the crank is to the front. Turn your QCTP 14.5º, cutting end towards the headstock and positioned as far to the rightas you can.. Regrind your tool with the right side, as pictured above, is not beveled and the left side has a 29º bevel and set in the tool holder with minimum stickout This rotates the tool holder away from the spindle while still maintaining the correct tool orientation. This should buy you the necessary clearance to cut your 3/4-5tpi Acme thread.Not quite following you with everything. Here's a top view of a rough mock up of what I think needs to be done.
The top of the picture is the furthest from the operator. The bottom is the closest to the operator. The left side is towards the head stock. The right side is towards the tail stock. The compound is magenta. The acme tool is green. The work piece is grey.
