Air grinders
Air grinders
I have a few air grinders some are better then others, you get what you pay for but the Chinese grinders one of their major issues is the air valve that throttles the air after some time air is leaking through the shaft of the throttling device then the O ring doesn't seal and there is a leak that gets worst with time. As any of you had this problem and made a better system. Bearings are cheap but sometimes hard to take them out but the leakage come long before the bearing replacement. The air grinders from Harborfreight have also this problem, well they also are made in China.
