I had some concerns about that myself, but since its  only 1.5 HP, the 
belt, if the proper backgear is used, might last long enough that its 
not a monthly item.  Too bad its not a polygroove belt about 5 ribs 
wide.  But those pulleys are platinum plated. BTDT :(

But a deal on a rebuilt Sheldon just materialized, so it could be moot.  
I'll make a personal inspection before I open the wallet.

Thanks Kenneth.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
