I've been planning ahead, thinking of ways to improve my brewing - CHEAPLY.
With this in mind I have been looking at YouTube videos showing mash tun builds and looking for perforated S/S sheeting to make a filter bed.
DING! Washing machine drums are made out of perforated S/S material, and ready curved to create a void (just like Jim's hotplate cover

... and then I got to thinking
they also have a drum that holds fluid - and a heating element - and a pump
... so, why not use a top loader, fill the drum with grist and bung it on a hot 'wash' for an hour or so!!!!
the dolly will agitate the wort and wash out the maximum sugar from the malt, the drum will act as a filter when it's done, and a quick spin will negate the need to sparge - thou a quick rinse cycle would do that too!!!
Be a little 'fiddly' getting the spent grain out again - but you can't have everything.
Well there you go - I said I'd had an idea - didn't say it was a particularly GOOD idea.
Cheers
Steve
