On this Stumpy Nubs video, James exhibits how one can take the “scary sharp” chisel sharpening methodology (utilizing 4 ranges of course-to-fine sandpaper on a flat piece of glass) to the following stage utilizing 320 and 400 Cubitron II discs for the primary two sharpening passes.
The scary sharp methodology works nice, however it may be tedious and time-consuming, particularly should you’re making an attempt to revive a chipped or tremendous uninteresting instrument or tuning up a model new chisel. The ceramic-based Cubitron discs assist speed up that course of. From there, you’ll be able to swap to common 600 and 1000 grit aluminum oxide discs for the ultimate 2 passes. After which leather-based stropping for a last polish.
On the finish of the video, James recommends a equipment that Taylor Instruments sells which features a piece of 5” x 11” dead-flat 5/16” thick float glass, a number of 5” 3M PSA sanding discs (2 every 320 and 400 Cubitron II discs and a pair of every 600 and 1000 grit PSA aluminum oxide discs) and 14 every 1/2” diameter urethane PSA bumpers — all for $25. In case you attempt to purchase all this gadgets individually on Amazon, it could price you as a lot or greater than this. I’ve purchased instruments from Taylor earlier than and extremely advocate them. Sadly, because the Stumpy Nubs video got here out, they’re again ordered.
