Abstract
A scroll saw having an unlimited throat depth includes upper and lower spaced apart blade arms independently supported and interconnected only by a blade at their forward ends. A spring biases a forward end of the upper blade arm upwardly keeping the blade taut throughout its reciprocation by a motor connected through an eccentric to the lower blade arm. The lower saw unit may be movably positioned on a platform or cart while the upper saw unit is slidably supported on a wall mounted support arm.
