I spent a few hours measuring and figuring and came up with this.
The sink needs a cut out 19x19". That width works well because the 10.5 gallon pots are 18.75" diameter and I don't want the pots sitting directly on the frame. The pots will sit on a grate above the frame.
The drawing shows 2 different diameters of kettles. The smaller is a Bayou Classic 1044, which is 11 gallons. I have 3 of them. The larger size is a Bayou Classic 1082, which is 20.5 gallons. I'll be getting 2 of them.
The left most kettle is the mash tun. The 2 others are boil kettles.
The 3 pumps will sit below the lower level, as will all the electronics, plumbing and controls. The entire space beneath the burners will be for storage. The 1044s are 17 1/4 inches tall and the 1082s are 17" tall, so both should fit beneath the burners.
This design uses all of the 50 feet of tubing I purchased. I bought it as 5 x 10 foot pieces.
Piece 1 will be cut 82, 19, 15 with 4 inches of left over
Piece 2 will be cut 82, 19, 15 with 4 inches of left over
Piece 3 will be cut 82, 27 with 11 inches of left over
Piece 4 will be cut 82, 27 with 11 inches of left over
Piece 5 will be cut 27, 27, 19, 20, 20 with 7 inches of left over
I might juggle these around a bit before I start cutting.
I'll use the 2 11 inch pieces to create a "firewall" between the edge of the the sink and the side of the mash tun.
The hot water heater mounts behind the sink. Its not a water proof unit, so I'll probably put a plexiglass splash shield in front of it.
The stand will have a stance of 23 inches, but an overall width of about 26 inches. The bottom long members will be set back inside the legs so that things that hang out like pump heads will not add to the overall width of the stand more than necessary. I'm hoping it will fit though any doorway I encounter.
The stand is nearly 7 feet long. It would be 5 feet long without the sink. I considered building it without the sink but I feel that the addition of the sink will make things a lot more convenient on brewing day.
My last brew stand had a 16x 24 fold out wooden shelf. I loved it and used it for many things, but it was way too small. This stand will have a 22 x 42" SS fold out shelf, making the entire unit over 10.5 feet long when extended. There is also going to be a 6" SS tray in front of the kettles to set spoons, tools, hoses, etc on. It found these two items at the local scrap yard in excellent condition.
I'm looking for input on this design. If you see anything that could be improved, I would like to hear it. I'm not promising that I'll incorporate everything people tell me, but I'll certainly consider it.
Thanks in advance.
