Copper manifold is for lautering. It is alternative to traditional false-bottom used in commercial breweries. In homebrew, people also often use "bazooka" - stainless mesh.
Manifold was good choice for me - cheap, efficient and can be easily made. One advantage is, that the parts are not soldered or crimped so for general cleaning, one can disassemble & clean it completely.
Part list:
Pipes are cut from one 2m long 15x1mm Cu half-hard pipe

Required tools:
Protecting glasses
angle grinder
microdrill with grinding wheels (0,5mm thickness, diameter 25mm)
round file - pro vyčištění vnitřních otřepů
vise
Consumption of grinding wheel was quite high - they are grinded away and also time to time i broke some of them. I've tried also diamand wheel, but it was not so good.
Lot of work, but it is the price for really narrow slits - just 0,6 mm.
