New V-belt makes speed changes easier

Changing the spindle speed of your Harbor Freight 8×12 or Lathemaster 8×14 lathe will probably be easier if you replace the factory belt with a size 3L300, which you can buy at most auto parts stores for about $5.  The original is so tight that changing the spindle speed by moving it to a different set of pulleys can be an unpleasant chore.  Richard on the Lathemaster Yahoo discussion group [no longer exists] discovered that the 3L300 is just a little bit bigger and it makes speed changes much easier.  I tried one, along with others members of the group, and we found that he was right.

Mine was made by Dayco and I bought it at a NAPA store.  Another store I’d visited didn’t have one in stock and they tried to sell me a heavy-duty version which I declined, because it cost twice as much and I didn’t think I needed or wanted a heavy duty belt.  (Addendum 3/18/2011:  I’ve heard that the Gates 6730 belt is the same size, 3/8 x 30-inches  or 9mm x 760mm.)

Why should self-interested companies be permitted to shift the balance of fundamental liberties, risking free expression, free markets, scientific progress, consumer rights, societal stability, and the end of physical and informational want? Because somebody might be able to steal a song?
