Once you have attached the long frame members, its time for the crossmembers. Measure the actual dimension between the long pieces (note: if your wood is slightly warped, these dimensions will not all be identical, so measure in each position a crossmember will be placed). We are using six crossmembers to give us a heavy-duty workstand that will be able to withstand plenty of pounding. Once you have the crossmembers, place them in the appropriate locations and space them evenly. Clamp and attach them to the long frame members with 2 1/2" (7cm) coarse drywall screws.
