quick question re: mash tun

[robsan77]

When building my tun I will be using tubing before the outlet as many have done so before but can anyone tell me what size I should drill the many holes for the best results?

not quite sure but i think its 1.5mm holes. but usualy on mash tun i didnt use holes i just cuts slots in the copper pipe with a hacksaw erery 5mm or so.

Generally it's slots for mash tun with copper pipe/tube, holes for copper/boiler.
You can use holes for the mash tun as c_b says. There are a few examples where plastic plates drilled with holes are used instead of tubing.
Basically a plastic version of this :thumb:
