Makes sense .
Locking the carriage and having your all your gibs set well will also help along with the correct 90 degrees angle of alignment of the wheels to the axis being knurled .
I found that when I did the very first knurl that the pattern was a lot deeper on the right hand side till I reset the compound slide accurately to 90 degrees by taking the measurement off the side of the knurling tool and the chuck face by trapping a six inch steel ruler edge to edge evenly across the gap .( the graduations and perhaps the play in the QCTP and QCTH all make for inaccuracies )
Another time when I playing I'd taken the knurler out the QCTH & on putting it back it was not dead on the centre line .
I only got a single ribbing over the whole work piece till I got in deep enough for the second wheel to start imprinting a feint impression .
Before the next time I'm looking to knurl I'll play on some scrap diameters many many times and record the exact diameters that give me the best knurl patterns from my bumper .
