oil system Thanks for the posting of your work. I would be keen to know how well its gone since then? I have thought about making a system like this, but Im the sort of person that doesnt like all the innards to be seen through glass. I thought an aluminium box would be great, that way it could also act as a thermal conductor to help disipate heat from the sides. If it also had fins the whole case could become one big heatsink. The Hardcore reactor is an inspiration too.
