In case you see both boards, yes I've also posted this on the groups.io board.
I'm puzzled by what to use for an accurate center height gauge on my 820. The saddle support arms extend too far forward to mount anything across the ways close enough to the QCTP, and the base is too pitted and covered in oil and chip to stand something there that would reach up to above center with repeatable accuracy. Can't attach anything flat to the cross-slide, because it's sloped and also somewhat scarred with old paint. While generally I turn the QCTP and touch off the tailstock taper, I'd like to not have to do that every time. Finally, the work I'm going to be doing will be pretty small, so I'll need precision; the "close enough" of the 6" rule trick is not precise enough. Would appreciate learning your ideas or solutions.
thanks,
Tim
