This is pretty much the same as the Ezee-Feed system. I built it using all cull plywood. I purchased the aluminum online from a place that will cut everything to size (the aluminum cost less than the shipping). The Transfer balls are available at Harbor Freight. The T-Track, knobs and hinges are from McMaster-Carr.
I supported the infeed using some aluminum L channel that mounts to the saw using a T-Track. This allows the whole unit to slide left and right fairly easily, although not as easily as I had hoped. I plan on changing this to use some aluminum extrusion and sliders.
Attachment Bracket: UHMW polyethylene strips on the back and underside help it slide.
Fence Clears the Infeed: This allows the fence / infeed to slide past one another.
Attached to the Table Saw
The Infeed Table
I tried to keep this as simple as I could. I mounted 2 transfer balls on the left and one on the right. My rationale was that I could slide the infeed over to the right when ripping long and narrow boards. This would give me plenty of room to stand to the left of the infeed table. There is one issue that I did not account for with this: the locking lever for the fence.
Need to Correct This: I am going to redesign the first support so that I can lock the fence between the transfer balls. This will allow me to rip long narrow stock.
Slide to the Right: The fence slides right and left. Here it is to the right. This allows me to still use the table saw without having to remove the infeed.
I mounted the legs to the table using hinges. I also mounted some casters so that I can slide it more easily.
Well sort of – Just trying out the rolling action.
