Description: |
Improvements to the inventor's inverted-swing-saw crosscut saw (as in patent 1,364,356) to reduce cost and weight while avoiding any risk of overturning while in use: the reciprocating mass of the saw was apparently prone to tipping the base when the saw completed the cut and was returning to its home position. |
