The inspiration - Blichmann's Top Tier system (Approx $700+ as pictured)
The result - A homemade 3-tier system made of scrap wood, some adjustable brackets, and casters ($32)
A little scrap wood
Built the center of the system with a left over 6x6. It was intended to be a column for the front of our house but only used the top 4 feet of it. There was a 45 degree angle on each side that was perfect for mounting the shelving brackets with some spacers behind. Also added some casters to make moving it around the garage a little easier. The style of the shelving brackets allows me to adjust if my system changes it the future.
Added some shelves made out of some leftover 3/4" MDF.
Here's the end result with the HLT, MLT and brew kettle/burner in place. Not too shabby for a couple evenings worth of work (had no blueprints/plans aside from the ones in my head or it probably would have taken half the time).
The brackets are supposed to be rated at 250lb when used in pairs...not sure if I buy that. I'll find out when I test it out tomorrow
I have some leftover wood that I could use to build some supports if need be.
If this thing works and doesn't warp to hell, I'll eventually install another tier for another burner as well as a pump to get my sparge water up to the HLT.
