I love the mobility and power of my contractor’s saw. I wouldn’t trade it for the world. But the setup does have some shortcomings, mainly when working with long boards or plywood. There’s just not enough support for my liking when making these cuts.
To improve on this, I built a sliding wing that attaches to the guide rails of my table saw. The whole system is made of plywood. The front arm glides in and out of the attached front tube, while the rear arm combined with a piece of aluminum angle straddles the rear rail. The two arms are tied together with the plywood wing end.
The aluminum angle that’s attached to the rear arm has a strip of nylon tape for smooth operation (left detail). The front arm has a groove in the bottom to allow clearance for the fence bolts (right detail). Both arms have a threaded rod epoxied into the ends to attach them to the wing end with knobs.
The plywood wing end is slotted to allow for adjustments in height as the wing extends.
