If you want a cheep hole cutter this might be ideal for you, I have this set and it works a treat.

i suppose a few slits along the bottom edge wouldn't do any harm as long as there aren't so many it would tend to splay under the weight of the mash.

there is a row of holes along the bottom corner.

so, you reckon a four bar 15mm copper manifold would work better?

i shouldn't have just thrown this together then.

brewsters millionths · Post by **brewsters millionths** » Sat Dec 15, 2007 6:37 pm

i think i might well do that.
i'm going to try holes instead of slots in the manifold as well.
both should be pretty good as a hop strainer as well so i can alternate and see which performs best at each function on each brew.
just need to sort the racking and propane supply now.

Looks like you're having some fun BM

I'm in the process of getting some quotes for perforated ss at the moment, but I'm not liking what I'm hearing.
Ã‚Â£198 for a 2m x 1m sheet of 304 ss, 1mm thick with 1mm holes, 60 deg pitch standard pattern.
It's actually quite resonable as you could get 18 (or more ?) x 30cm fb's out of it which is Ã‚Â£11 per fb.

Im going to try getting one cut to size (44cm dia) tomorrow....we'll see

brewsters millionths · Post by **brewsters millionths** » Sun Dec 16, 2007 11:35 pm

so how much for two 50cm dia ones then?

Just pm'd you about that as it happens

I have a 38cm square of that sort of material. I'm just trying to think how to convert to a FB. I would love to be able to cut a circle out of it and get it rolled/panel beaten ala the More Beer one, but I can't see that happening

Another thought I've had is to make an octagonal shape and then fold under the edges (say 1.5cm) by 90 degrees, while a full width FB would be nice, I don't think it would be essential

if you have 38cm square why not a square one?

4 brews later and no stuck mash so far

the only change from the picture is a JG connector from the pickup pipe to the outlet/ball valve in the wall of the mash tun.

Because its actually 395 by 400mm, and over 560mm on the long axis, which means that it wont fit in the 44cm dia Tun

Although I do love Mix design, what I'm thinking is an hex/octagonal design to give me the maximum surface area in the Tun, and turn around 10-20 mm by 90Ã‚Âº along the edges to give me a raised FB, what I may well do then is to add a mesh screen (Ala Hop Stopper) under that to help stop the fine particulates that manage to get through my current FB.

TBH I suspect that the Hop Stopper would do a more than adequate job on its own, I'm just not 100% convinced of it
