I need to ask some dumb questions anonymously
I tried to buy some lumber today and I just wanted to make sure my math was right… apparently some questions are too dumb to ask. Since this is anonymous, please give any constructive criticism on anything below!
Ok, gravel foundation for a resin (Keter) shed. Shed is 10 x 11.5, let’s make the gravel pad 11 x 13 for drainage reasons. The perimeter is going to be 4x6, since a single timber will be tall enough for 4” of gravel (5.5”).
If the timber is going to be partially or fully buried, then I figure I can’t butt the two corners together and screw one into the other’s end grain (I thought end grain was a no no anyways!) - lap joints it is. If the width is 3.5”, then I actually need the timber to be cut/measured 10’7” and 13’7” for the lap joints and keeping the interior perimeter 11x13 - correct math?
Or have I overcomplicated everything and when people talk about perimeter measurements, are they being specific about the Length of the individual lumber ignoring any corner joining math?
P.s. I really wanted to build a deck so I could nail framing through the Keter floor but I’ve been convinced that’s a stupid idea. I can’t even measure a gravel pad without asking reddit - a deck is out of my league.
