why use pumps?
 
Well this question might reflect my ignorance or noobness but i am trying to step to all grain and really enjoy brewing indoors for quite a few reasons, going electric i was reading pots and pumps are a large expense. Using keggles to reduce cost would i be able to weld up a single tier table with three scissor type lifts to utilize gravity as a means of transfer? would this work, what is the benefit of using pumps other than them being a means to a totally automated system?

I think you have a neat idea kosmokramer. My only concern would be the lifting of very heavy tanks filled with hot liquid. It would be difficult to make it a safe rig. You would have to add a lot of weight to the base to ensure it wouldn't topple over. I would also consider adding a way to make sure it is level before you jack up a kettle.

I was think something like one of these modifieed a bit. I work for the railroad and we use the to lift valves that weigh about 150, at about 8 pounds per gallon plus the weight of a keggle should never exceed 200 pounds. These lift level and doesnt look like two much modification would me needed other that removing casters and perhaps welding a plate to the tranny lift as a tabletop. If i weld up an overall rig of 16 gauge inch or inch and a half tubing with heavy duty casters to accomodate i think it would be pretty stable. Am i missing anything, is the general idea plausible?

I still think the whole rig should have a way of leveling. It doesn't matter if the keggle is level unless the rig itself is level first.

true! hmmm, i operate a crain when im not rebuilding valves and our small 15 ton crane uses 2 simple 1 inch sight glasses as means of determining level. mabe instead of casters using adgustable feet in combination with sight glass to manipulate degree of level as each table is lifted and for added assurance? other than stability Paymygasbill77 does the idea make sense?

How about casters and feet that screw in and out. You can move the feet all the way up to move the rig and lower them to level it.

The other thing I would include is a means of dumping your mash tun.

I love the idea but is this cheaper and more reliable than just buying the pump?

The brew sculpture I am building is an electric 3 tier gravity rig with an arm and pully system at the top so I can safely and easily lift my keggles over my head.

I am also making it so all the pieces can be bolted together and taken apart for easy storage.

kosmokramer 10-03-2011 05:54 AM

So you are using gravity rather than pumps as well huh? why would you need an arm and pully system if it is 3 tiered? Do you have any photos?

I have a bad back and it doesn't feel like lifting the keggles up and down a ladder. I just started building it yesterday and I don't have any pictures as of yet. I will post some when I get around to it.

cool, im pretty new to brewing and already know i have found a life long hobby, im also a new homeowner and a grad student so as much as i want my bad ass rig now, it may take me a bit. I do have a bunch of 1 1/2" 2" and 5/8" tubing laying around from the gate i just had to make so i can at least get started with something.
