Nipples?
Well - I'm looking at your guys' designs - and thinking about making my own - but I'm not sure what to do about nipples. No - not that kind of nipples. The metal kind that are on waterblocks (I believe that's what they're called?) Surely you can't just mill them - they have too complicated of a shape and they're round. Or have some of you tried? Do you buy nipples somewhere and just weld them on? Thanks!
