Me too! I built the whole thing, no free pallets involved. I cut my wood at 26" and that just does not work with the pallet's that I come across for free. The 2x4's 8'- $2.05 10'- $3.33 12' $4 then there's 2-12' pt and a $35 box of screws, and that doesn't count the other screw's I had and several tubes of const. glue also on hand. All the lumber was cut in half and virtually zero waste. The Hemlock seem's to be pretty durable outside, I have a sawbuck that's been outside for about 7-8 years now with no trouble, and with a cover on these box's they will get no direct rain. I'm telling myself that I should get 10 years use at least.
I saw a member's alternate design on another forum that also involves no pallets. It really is a simple design and should be $20-30, it's only a single row but I can live with that for a $50 savings. I'll build a couple of these to see how I like them.
