If you can get a hold of Jazzafish on here, He has my old bucket in bucket mash tun or knows who he passed it on to...2 buckets(one with tap, other with gazillion holes in the base) and wrapped in 2 layers of bubble wrap(thanks PoL)
Did many a fine brew, just that the lip of the lower bucket was the liquid limit (20litre)..and I forgot a few times...
You can batch sparge, but need to split the sparge water into 2 -3 additions....Mash, drain,1st sparge,drain,2nd sparge and drain
