IIWM, I'd clamp the work piece, plunge, lock the spindle handle and then un-clamp the work piece run it through and re-clamp before messing with the spindle again.
JPG had me questioning my own sanity for a bit today, as I didn’t think that a lower routing RPM on a Mark V should bother me too much. The clamping/unclamping procedure that you outlined cleared things up for me.
Unless you’ve had hands-on experience with a Shopsmith OPR, you probably don’t know that a simple twist of the handle on the plunge lever will solidly lock the plunge in it’s current position. After I had used mine for a while, that feature became so intuitive that I forgot it is unique to the OPR. One less hand required.
