Hello - I noticed that the Tormek 2000 looks different than the Tormek 2000 I purchased in 2001. Are the parts the same? Also, is it normal for the powder coating to be peeling off? I recently took the wheel off for the first time and noticed alot of corrosion and peeling. I have also noticed that the main shaft moves up and down, does this mean that I need bearings? Thank you for your help, Stephen Davis.
