Are you cleaning your machinery down with compressed air Bruce? I watch a lot of machining videos on YT and everyone's mills & lathes always look so pristine......not mine....mine look like they have been rode hard and put away wet 
My copper swarf catcher I couldn't be without, does keep 99% of swarf off the lathe bed and I can just sweep it off to the back swarf catcher and then into an oil drip tray (from an auto parts shop) for removal.
" Are you cleaning your machinery down with compressed air Bruce?" never Jim, (per Tubal Cains instructions) although my Kurt vise is a pita to get into the nooks & cranny's. I do clean it after each use (mostly) now that I'm retired. I saw your swarf catcher & may have to fabricate one of those, i like the concept.
I've worked in plenty of machine shops where compressed air was in constant use for clearing chips. However, these were all big open floorplans that allowed for easy sweeping later. My little crowded storage-room/shop has no place for chips to sail off to, so I do all my cleaning with a brush and a vacuum. Works well for me in my situation.
As an aside, the same is true with fly-cutters. As nice as they can be to use, there is just no place for those chips to fly too!
Nice job on the spindle readout Bruce!!!
