Hey great. Finally got my bench built last week. It's one of those 2x4 Basics kits from Cabela's. I made the frame from 2x4s, the benchtop has a 2x10 up front with 2x6 spanning the rest of the top. Measures 7 feet long, 30 inches deep and is 35.5 inches tall.
The top is supported by three 2x4 fasted to the top frame at 2.5 feet inside plus dead center at 3.5 feet by joist hangers and drywall screws. The rest of the boards are fastened with 2 or 3 inch coated deck screws with the square drive. The two inch screws are used for the leg and frame joints and the top is held down with the 3 inch screws. The 2x10 front, which the presses are mounted on, is screwed down three times on each end plus every 12 inches up front. On the 2x6s, it is just two on each end plus a run up the middle.
The two bottom shelves aren't done yet but they will be supported by 2x4s and joist hangers like the benchtop is but just be 3/4" plywood. I will make some drawers that slide out on the shelves so that I don't have to add lights down there but be able to keep it organzied and convienent.
I have the Lee Classic Turret press mounted to the right, with the Dillon swager around the corner. The MEC 600jr is on the far left, turned in for easy reach of all the stages. The Dillon 550 is getting refurbed at Dillon but that will go in the right of middle. I'm getting another RC and that will go between the Dillon and MEC to the left of center.
