right guys. I've decided I don't like my Design Technology options. Plant pot holders...automated wine pourers, candle holders and rubbish.
I've PRETTY much decided i want to make a simplish waterblock. So i'd really appreciate people parting with their knowledge.
Note: I want to try and include as MUCH into this project as I possibly can:
Various machining processes.
Methods of inducing turbulence + some theory
Water Jet/accelerator plates to increase water flow/velocity.
Water tighting (how do you put the plastic polymer on the metal and water tight it (i've see often you put some black rubbery looking thing insome grooves cut around the block...explain?)
that's all I can think of at the moment
But please let me know some designs, not sure what resources i'm available to but I'd like to know what machining processses there are etc. Cheers

Appreciate nice long answers which I'll learn a ton from
