I used 2mm for my hop filter as well, drains nicely .. :thumb:
To drill them I punched first ever so slightly with a nail to stop the drill slipping at all. Maybe obvious, maybe not, but I am mentioning anyway.... :whistle:
thanks for the info I thought that 1 mm was going to be a bit of a nightmare thats why I asked :thumb:
I fortunatly am the proud owner of a drill press so shouldn't have too many probs drilling it
thanks for all the advice
I have a piller drill but with a thin drill bit it will still flex and slide just give a little tap with a nail first :thumb:
Ive only drilled the underside of my copper pipe for the hop strainer. Dont know it this is right or wrong but im working on the assumption it wont block when the hops settle on the top.
