Get Pegboard cut to 16.5" x 23". Get a bundle of 2x2's (9 Total) and (5) 1x2's for the tub guides. They are 28QT Sterlite Tubs. Youll need 3" Wood Screws, and 1 1/4" Wood screws to screw the pegboard onto the 2x2's. Cut (10) 20" Sections of 2x2's and (10) 16.5" sections of 2x2's. The Support Beams are 41" 2x2's. Cut (8) 1x2" for the tub guides that sit on top of the 2x2's you attach to the pegboard. Thats all the cuts that you have to do.
I had Home Depot cut the pegboard, and remember when you get that cut, they have to compensate for the blade width. I prefer a snug fit for my tubs, so I have about a 1/16" space inbetween the tubs and the pegboard.
I used Thompson's Water Sealant to seal the wood. I let it dry for 36 hours, then assembled it all together.
Make sure you predrill your holes before you screw in or else your wood will split. You can buy pre-sealed wood, but its a tad more expensive.
Keep in mind that this is a rough draft build, and it pretty much came from my head. There are plans online for other racks, but I just sort of looked at it and made my own design.
All together, tubs included, it should only run you about $55-65 to make this depending on your lumber pricing. The tubs I have were only $2 a piece, but I get them tax free and they were on sale at the Navy Exchange.
Im constructing a hatchling rack very soon, 10 tubs, and I will post a picture of it if you'd like and somewhat of a summary of how I built it.
