I'm trying to attach a 1 HP powerfeeder on the back surface of my shaper. The cast iron table on the shaper is about 27" square and if I attach the feeder to the rear corner, I'm afraid the fence attachment will bump into it when the fence needs to be pushed back. I thought about adding a piece of steel angle iron (3.5x2"x.25") to the back edge of the shaper. Anybody got any suggestions?
