Making frames and stretching canvas

Here are some photos of the frames I have made and the canvases I have stretched. The frames are a combination of 1x4s and 1x2s. I paintex them flat black. 
The canvases are linened stretched over 1x2 stretchers (I beveled them with a router to minimize the area touching the canvas. These are primed with gesso, but I am about to start using an oil ground.  They still need to be toned.
