Mash Tun Manifold Slits.....how many and how big?

[BritishBelgianTwst]

Hi all,

I've just finished the manifold for my coolbox mash tun and was wondering from your experience how many slits I need to cut into it and the size of them? I was thinking the more the merrier but wasn't sure about the best size - too small and I may get a stuck mash, too big and I think I'll get too much crap going through.

Thanks for your advice - I've never done a mash in my life so it's all theory for the moment.

Thanks,

Paul

Width of a hacksaw blade, approx 1cm apart and cut halfaway through should do you. Mines like this and Iv never had a stuck mash - touchwood!!

Hi

I have made a few over the years, some better than others. I find that slits cut with a junior hacksaw(stress junior, I have found full size hacksaw blades produce a slit that is to wide) work fine spaced about 10 to 15mm.

I'd go with the width of the hacksaw blade at 0.7mm intervals, the details are here

I'm assuming you meant 0.7cm or 7mm?
