Below are the two 30000RPM routers wired in series which I will be using to primarily start the twin.

I have tried spinning the turbines up using them, running at 60PSI Oil pressure, and they work excellent !!!

The two 16mm sockets fit the two domed nuts on the end of the turbine shafts perfectly with a good amount of free movement so as to not put too much lateral strain on the bearings. The sockets have a countersunk 8mm A2 SS Allen bolt through them, tightened, locktighted and then the out shaft lathed to 6mm to fit the routers.






I refitted the end plate to the end of the combustion chamber and added the P2 gauge. If the gauge suffers heat stroke there then I will be adding a short copper pipe to spacer it away from the CC end. It's only there temporarily anyway, just for testing purposes.
