When I started thinking about designing a spline jig, I knew I wanted a handle to hold it tight to the fence & table, & maybe a handle to push forward, & I didn’t want a bridge over the fence ( don’t like those). So after some time, this is what I came up with. I know some will think it’s overkill for such a small cut. But this way, I can secure even a good size frame & have my hands free to apply pressure where needed As I get older, I try to get safer. The left side face has oversized holes that fit over the 5/16” x 6” carriage bolts. An old rubber pad,( in a previous life it was under a scroll saw) protects the workpiece. I like the versatility the clamp slots give me. I used bolts to attach the arms, with 2 thoughts in mind. I could remove the front fence if I wanted to make a spline miter joint, & when the bottom got chewed up, I could remove the arms, rip off the hardboard face & replace the faces. Easier to do with bolts instead of screws I think. I think with smaller frames, I probably won’t need the knobs tightened, just apply pressure. Made this from a piece of Birch (not Baltic) plywood from Lowes. Lot’s of plies but lots of voids & a bit of warping. Veneer was really brittle & unforgiving. It was an interesting jig to design & build. Good therapy for a guy getting hammered by the recession, especially the architectural industry.
