Not an expert, but even after measuring more than twice my one cut was probably 1.5-2mm short on the latest fork install. So a couple threads short of full engagement or so. Next time I’m just gonna plan on an extra spacer or two. Still a bit more than half the threads engaged on a Tange Levin CDS. Not bad enough to remove the one washer (has a washer that sort of sits inside a recess on the race for I guess better sealing). No issues even with some bumpy miles, maybe 500 miles so far and checked it pretty recently, everything still tight and snug. Still can’t believe I did it but whatever at this point. YMMV
