While waiting for material for the water pump I have been making the water manifolds. I started by turning the flanges on the lathe. From there I moved them to my cnc router and cut the flanges to shape. After that I drilled the screw holes in the flanges. And the last step was using the mill to cut the relief for the ferrule.

I used a high temp silver solder paste for mounting the ferrule to the flange. This was my first time using a paste, I think it will be my go-to for small parts from now on. I made a sheet metal shield to protect the engine while I soldered the assembly together. I drilled through the flange assembly into the tube as the last step.

To complete the cooling system I still need to build the water pump. I have bearings, some o-rings for the belt drive and a bit of aluminum on order.
