I recently added a second 1/32 sanding block to my Razor arsenal, and it made a world of difference. Using coarser grit can really cut down on the time that the Razor is spinning, truing a tire to an edge as keen as, well, a razor! Some side profiling and then a touch to the fine grit and the tires are ready to go.
Unfortunately, I've another problem now. This increased productivity has lead to an increase in tire debris. After a couple of sets, my workspace is in need of a bath. An improvised truing booth made from a tissue box does help wrangle the urethane dust to at least the front of the unit, but it mostly ends up in front of the Razor and all up my arms. I've reversed polarity to cut down on some chatter and axle hopping, but the debris situation has gotten worse:
Am I just an idiot or does everyone's workspace look like this?
What do you guys do to keep your tire dust manageable?
