When we bought the house, I had long-term plans to build a larger bench (right after closing and insulating the third bay of the garage to become a workshop, and refinishing the deck, and replacing the garden shed, and...), but that never happened. With the move last year, that turned out to be a good thing.
Now that we're mostly settled for the time being, and with the new .308 in the stable begging for precision loads, I decided it was time to start reloading again. I ordered a 2x4basics workbench kit from Amazon ($70 to my front steps) and picked up a dozen eight-foot 2x4s, a sheet of 3/4 B-C plywood cut 24/24/24/12/12(x48)*, and a 24x48 piece of 1/8" hardboard (Masonite).
I took things home and cut the following lengths of 2x4s:
12 - 48"
6 - 21"
2 - 39"
4 - 30"
1 - ~48.5"
(I ended up with a full 8' and a 40-odd-inch chunk leftover, which is fine.)
Then I screwed all the boards into the brackets following the handy pictorial "directions" included with the kit, and ended up with a nice 2'x4' bench. A handful of 1" drywall screws anchored the hardboard on top, and I built the shelving up on top of that, with the heights adjusted so I could get kegs of powder on top, and have plenty of room to work underneath.
Initially the bench felt wobbly - not weak, just that it was teeter-tottering on the legs. That changed in a big hurry when I started loading it up with equipment and components. It's now rock-solid and not going anywhere.
I picked up a couple architect-style LED desk lamps from Walmart and discarded the base in favor of drilling a 1/2" hole in the top shelf I'd built. A power strip on the side of the bench feeds those and an RCBS electronic scale, plus the tumbler as needed.
A few 2" lag screws hold the press down, and tonight I'm going to grab a small bench vise from Home Depot to mount on the other end.
End result? A pretty solid bench for a minimal investment (about $200 including the lights and power strip), no fudging around with building corners, and a great space for me to work on reloading or other gun stuff:
