The right tool for the job...

Another issue I found while test driving the '40 was that it overheated.  These motors do not run that hot, and the radiator is larger that some other 235 setups that I have seen. 

I never liked how the thermostat housing was.  The thermostat was higher that the radiator cap.  With this setup, there is no way that I could get all of the air out of the system.  I figured that it needed to be changed as it might be contributing to my overheating....

After a bit of measuring, I came up with this.

This provided me the opportunity to play with a new high helix endmill...

This thing is awesome...I was taking 0.75" depth of cut, 0.125" step over at 60 inch per minute.  The machine didn't even complain a bit.

I like aluminum....
