Stair Tread Jig

You can buy these fairly cheap, however this is very cheap. You will need 4 3/8" nuts and bolts. Other than that you will need to cut a peice of “1x” or .75" scrap to the lenght shown in the picture. First lay your blades out to where they sit againtst the edges. Lay a tape measure across the tow at the points shown below. In my example, i need a board that is 25.5" long. I secure that board with 4 .75" screws on each side. Holes are countersunk to avoid marring the new treads. The slack that is created is made up with the slots in the connectors.
