Hey there John. What we did was find the odd length of 1 X 4 pine, cut two 12-inch lengths, then put 2 1/4-inch thick X 1 inch high X 12-inch long pieces in the bottom part (you know, some scrap pieces of your cove and beaded strips work wonders here, just nest 'em together), and a temporary 1/4-inch thick spacer at the top half, clamped the whole thing together, drilled three holes equally spaced along the bottom, then put in machine screws, washers and wingnuts. You could glue the two 1/4-inch thick pieces onto on of the faces, but not both: you want to have a way to clamp the piece you're going to cut a scarf on. We didn't because we wanted a way to change the orientation of the "permamnent" strips, ie, one side is coved, the other side is beaded, which is a perfect bed for scarfing a cove-and-beaded strip (more below) Next, saw a sharp angle into the top of the newly made clamp, taking care to saw a straight line down to the "permanent" pieces. Voila! You now have your cheap and effective adjustable clamping scarf doo-hickey widget thing, good for all sorts of things. Some details that come in handy, change the orientation of the permanent pieces in the clamp to "bed" the subject piece you're going to cut a scarf on, reversing the cove for the bead as the need arises. Use a thin bladed (thin kerf) razor saw which will track in the saw cut nicely. Also, the sharper the angle, the bigger the area for gluing, and hence, a stronger the bond. I hope that all made sense, the jig worked wonders for us. regards, luck, and cheeers (I think I'll have another Nut Brown ale now) TnT
