I have recently taken up woodturning. I have a Tormek, which handles the sharpening process very well. I have added other grinding wheels which have speeded up tool reshaping, however, the process is still slow. I have very mixed feelings about using a high speed dry grinder.
I recently discovered a ¨new¨sharpening system with some interesting possibilities. It is called Sharp Fast. What originally attracted me to it was the designer and demontrator, Dave Hout. I have known Dave for more than twenty years. He is an outstanding woodworking teacher. (He is a retired woodshop teacher.) Over the years I have taken two classes with Dave. He has a delightful expression for how tools should be, ¨Stone simple and indestructible.¨I think he has succeeded with these ideas with Sharp Fast.
The primary purpose for Sharp Fast is sharpening turning gouges. It looks particularly well suited for narrow one inch wide grinding wheels. The point of contact on the wheel remains the same throughout the arc. This makes me think it might work quite well for both reshaping and sharpening turning gouges, both bowl and spindle gouges. The jij is designed such that switching back and forth between spindle and bowlgouges requieres no adjustment, with only one adjustment being nexeccary when changing the amount of wing amount. Results look quite accurate, repeatable and fast. I think this might be an excellent match for a variable speed belt grinder. The speed could be faster than a Tormek and slower than a ¨slow speed¨grinder. Being able to quickly change belts would makegrit changes fast. The 1x40¨brlts are as wide as a standard one inch wide eight inch diameter grinding wheel.
Thoughts?
Another idea, the motor on my Kally has a reduced shaft diameter of half inch. The 1725rpm motor on my lathe also has a hald inch diameter and uses a four speed pulley arrangement. I have thought about switching motors and using the PSI variable speed motor with the four speed pulley for my lathe.
Agiain, thoughts?
