Compared to most crank grinders, the 485 is massive at 11 lbs. but was the baby in the Goodell Pratt family of grinders. The 22:1 gear ratio spins the the wheel at over 1300 RPM with a leisurely 1 crank per second. The gears are beefy and run smooth. This is a high quality crank grinder, as good as you will find.
Grimy and neglected
The cleaning took it's toll on the badge, should have covered it with tape.
