thank you, thank you, thank you!! the lumber that i had in the garage wasn't exactly what your plans called for (2x4s and 1x10s), so i adjusted the length of the all thread to accommodate the depth. also, one of my 2x4s was kind of wonky and i was worried it would jeopardize the stability of the set - but it's totally solid! the shelves are level and aren't going anywhere!! :) (i threw all of my body weight against it, and it's totally solid!) it's approx. 4' wide by 7.5' tall.
Thickness planer. A thickness planer is used to fix surfaces of imperfect wood. If you are picking up less than perfect wood from the lumberyard, wood with some surface defects, a planer will let you fix that wood in the quickest time. A thickness planer pays for itself quick as it allows you to buy cheaper wood that doesn’t have perfect surfaces and fix it yourself. Be careful though. You loose wood during planing. So the remaining amount of wood still has to be worth the price you paid for it.
