Title: Rolling miter saw stand
Inventor: FREGEAU KEVIN J
IPC: B23D47/02
Filed: 2009-10-22
Abstract: The Rolling Miter Saw Stand is used for cutting long material using approximately half the space required by a conventional miter saw stand setup. The Rolling Miter Saw Stand operates on a rolling track system, allowing the saw to roll from one end to the other. This enables cuffing at each end without having to rotate the material lengthwise.  There are four material support blocks on the stand; two are fixed at the ends and the other two can be rolled wherever support is needed. The two rolling support blocks are adjustable in height, thereby accommodating any cross-cutting saw. The tracks are designed to stop dust from entering the rolling track system, keeping the track free of debris. This allows for no maintenance and ease of use.
