away from Tesla turbines. I've already played with them and they are a
pain. I ended up laser cutting my disks then using #4 flat washers as
spacers to get the roughly .015 spacing between plates. The problem was
dealing with the lack of flatness in the sheet stock. Granted I was
using it as a power turbine, but it was still
painful.<o:p></o:p></SPAN></P></DIV>
