Right now my work shop measures 30' x 60' with a tall roof. It has a 14' roll up door. There are no lights yet since there's no power. I have my Ram 2500 and 24' Sportsman Masters 247 in there. Next year I hope to frame in a 42' x 8' man cave. Going to put in 8' ceiling in the cave. Put work 2' deep work benches on the outside wall where the windows are and put storage on the inside wall. Build in the workbenches and I'll have enough room for all my reloading equipment and tackle crafting stuff.
I've got three progressive reloading presses, a single stage and a PW 375 shotshell reloader. RCBS Pro-melt pot, close to 100 molds, painting stuff, tying vise along with all the other "stuff". Going to use every bit of that 42' of workbench.
