The heads of the lag bolts of both sets of boards should be facing the same direction. Place the set of B Boards, cut side up on top of the set of A Boards. Place the other set of A Boards on a level surface with the cut side down. Using the power drill or drill press and a 1 inch drill bit, drill 1-1/2 inches (on center) from the end cut of the boards. The heads of the lag bolts of both sets of boards should be facing the same direction.Ĭlamp the two sets of boards together very, very tightly. Place one of set of A boards on top of the set of B Boards. The lag bolts should be horizontal to the ground. Set B Boards on a level surface with the cut out side down. The other set of the A boards will be allowed to slide along the length the rod. One set of the A boards and the B boards will be secured to the threaded rods with washers and nuts. The three sets of boards, A boards and the B boards, that were bolted together in Step Eight will be aligned vertically. (use thin pieces of soft wood or cardboard between the clamp and the birch so you don't make any dents on the surfaces) Spread glue on the X'd side of each piece.Īlign the boards in each pair, glued side to glued side.Ĭlamp together tightly. Repeat 2 - 12 for the other pairs of boards.įind the nicest, smoothest side of each piece. Use the Dremel to clean up the lag bolt counter sink holes. The lag bolts will act as your clamp for these pieces. Put a washer and nut on each of the threaded ends and using a socket wrench, tighten all of the nuts. You may have to use a hammer to tap the lag bolt through. Realign the boards and put a lag bolt through each of the holes. Mix the wood glue and spread on the inner side of the boards
See diagram.ĭrill countersink holes on one side of one board. OR use a drill press.ĭrill one hole in the center and two at least 3 inches from the ends. Place over concrete masonry units (cement blocks) and stabilize it while you drill and you don't drlll through the floor. The A boards will form the Top and Center Bars, the B boards will be part of the Base, and the birch plywood will act as the plates of the Top and Bottom platens. You will be working with Boards A and B of the maple and also the birch plywood. Keep all the cut boards in their groupings (1 inch boards together, A’s together, B’s together, etc.) Or, you can clamp the board to the saw table.Ĭut the following pieces: From the 2 inch boardĭ: 5 – 18 inch lengths, 4 inches wide From the 1 inch board
Again, if you have a long board, have someone help you support the board while you make your cut. Use the radial arm saw to cut the lengths. Set the boards together out of the way of your work space.ĭepending on how long your maple boards are, it might be easier to cut them into shorter lengths before trimming the rough edge to the correct widths If you have a large piece of plywood, have someone help you as you push the plywood through. Use the table saw to cut four 18 inch by 22 inch the rectangles from the birch plywood.

Note: With hardwoods, generally, there is one finished side and one raw side. Larger pieces of cardboard or a blanket for padding to prevent scratching the wood Optional 2 concrete masonry units (8 x 8 x 16 would be good).Heavy Duty Drill or Drill Press (needs to be able to drill through 4 inches of maple)
