Plane
Plywood 3/4” Bottom
Sides Wood of your choice .25-.375 thick
Sand
Liner
Granite Slab or Cutting Board Material

Step 1: Cutting Your Table Sides and Bottom

Making the 4 sides
cut side pieces to length and taper one edge of each corner piece. If you have a table saw, make a tapering guide as shown in the drawing to hold the stock safely as you slide it along the saw fence [ 1 ]. Otherwise, cut the parts with a jigsaw. Note that one tapered piece on each panel is 11⁄16 in. narrower than the piece on the opposite side. This makes up for the thickness of the overlapping piece on the adjacent side. to ensure consistently shaped panels, build the table sides on an assembly platform. lay three panel pieces (one straight and two tapered) on a piece of plywood using 1⁄8-in. spacers between them. Fasten guide strips to the plywood to hold the parts in position [ 2 ]. cut each cleat a hair shorter than its theoretical length and fasten it to the panel side [ 3 ]. Inset the cleat by 3⁄ 4 in. to allow space for the adjacent side.

Step 2: Assembling Your Table

Before assembling the table, use a block plane to slightly bevel the edge of the narrower tapered piece of each side. It should be a shade under 90 degrees. use a band clamp and some thin wedges to hold the sides together, then drive deck screws through the upper corners of the table [ 4 ]. Next, bore a series of 1⁄16-in. pilot holes along the tables’s corners and drive a finish nail into each hole; don’t drive the nail into the adjacent panel [ 5 ]. remove the band clamp and the screws; apply glue to the joints. reassemble the box with the screws, and finish driving the nails [ 6 ]. use a nailset and drive each nailhead slightly below the surface so that it can receive exterior-grade wood filler. cut the bottom piece and screw on
Next you line the inside of box with a liner…( I used felt ) .. Let dry ...pour in sand till about 1inch from top. You will set the granite slab on top of the sand.. The granite should be floating on top not touching your table edges….You are ready to go.. Place your equipment on the granite.. This will ensure a vibration free work area..
My equipment is an old school record player that I just got and it was skipping from the bass speaker under my desk.. Now I can really thump it and my player doesnt scratch or skip. An extra touch is to put 4 rubber feet on the table also… I didnt put exact sizes because you will want to make it according to your equipment needs.
