I must be lucky. If I need lumber I go to the local saw mill and if they don't have it they cut it for me while I wait. Best of all a 2X4 actually measures 2X4 not 1 3/4 X 3 4/4, and they will cut it out of whatever I want. Oak, Poplar, Pine, Yellow Pine, Walnut, etc...
Lucky on the parts store front to. Got a fairly close parts store that has been in business long before I was born and is still family owned. In fact they have 3 generations of family working in the store. One of those good old parts stores that actually know's what your talking about when you need that special widget. Huge warehouse full of parts. Needed a set of front brake shoes for my 1952 Chrysler Newyorker last year and everyone else just laughed at me. Gave them a call and they said "let me do some digging and call you back". Called me about a hour later and said they had 3 1/2 sets of vintage 1960's manufactured asbestos (sp?) shoes and that I could have them for FREE. All I needed to do was come pick them up. I would be lost without them. A real parts store for cars, trucks, truck/tractors, farm tractors, rebuild starters and alternators on the spot, make hydraulic hose and lines, full service machine shop, radiator repair. One of those you name it they either have it, can get it, can fix it or can make it. The kind of store you walk into, get what you need and walk out saying "I love this place!".
