I thought I'd share my experience as I've learned a lot from this thread and want to give something back..
I bought a 2nd hand Buffalo 30ltr last year and went about converting it.
First up came a
tap conversion then a thermostat bypass with
simmerstat (
don't touch the cheap DPDT switches on ebay, they meltdown!).
Simmerstat doesn't do exactly what I thought it would, rather than controlling the power of the boil it cuts out and in again. Not a dealbreaker as I've worked out the ideal breakpoint but would be nice to master it,
any ideas greatly appreciated.
I then set about trying to source a grain basket which proved fruitless, at least in my price range, so I made one from a cut-down fermenting bin, a splashguard, some threaded stainless rod and dome nuts. Works a treat; strong, good mesh gauge, and easy to keep clean.
This is then suspended for sparging using some hooks I made from stainless steel tent pegs. Bit fiddly but it's cheap, and means no welding, screws or leaks.
Apart from being basic and lacking proper temp control the only real drawback is the height of the tap which currently adds an additional 8ltrs to the mash water (although I can get this down to around 7), so it restricts grain bill size.
I've just bought a
mini mag pump and am in the throes of sourcing a mesh screen for the top of the mash, so I can recirculate the wort (if I'm lucky the Robobrew top screen will fit perfectly).
If that goes well I may install the pump internally, fit some fixed pipework and might also fit a pump inlet onto the boiler floor bypassing the tap. This will also solve the extra mash water issue.
That will probably be it but I might, just might buy an inkbird to finish it off.
So far the outlay including boiler is around £150 so the integrated pipework and inkbird would take it to north of £200. Not sure that's economical.
Hope this is of interest, comments and questions welcome.
