Yogi, where did you buy the 4 X 8 X 2 lip seals for your coolant pump?

Thanks.

Alright, I have another part to add to the engine, as I still work on the cooling system.

The fan is made from .040" 3003 aluminum sheet. I used CA glue and masking tape to secure the sheet to a plate. The use of masking tape seems to be popular by a number of YouTube machinist, so I figured I would give it a try. It worked very well. To release, I warmed up the parts until the bond let go.




The fan blade after deburring:




To press the radius into the blades, I 3d printed a die with the required shape. This was an experiment, and it worked flawless. I'm certain this would work on even thicker material.








The last part was to twist the blades. For this, I used the bending die again, to gripped the blade firmly, while using a protractor to twist each blade the same amount.

The finished fan:






The fan installed on the engine:





Thanks for following along, and stay tuned for more.
Yogi

Great work on the fan Yogi. Liked the 3D printed tooling! Looks like the engine's almost ready to bark.

Yogi,
The engine looks great, looks like one more reason to get a 3D printer. That fan looks really good.
