No idea; was just throwing that out there. Seems the logical thing to do given the success of the waterblock construction forum. It would depend on the number of blocks and the regularity of testing I guess. Let me get the system set up (I keep getting distracted) and see from there. If it were 2-3 times a year involving 5-6 of the best blocks I could probably do for free; if it became more regular and more blocks then perhaps a fee to cover wear and tear on my lazy ass
