A little 9 time

No work on the 10 this week other than ordering the cylinders and piston pins for the engine.  This week and probably the next week are dedicated to the 9A.  I mentioned working on the oil cooling system last week and this week I hope to finish that process up.  My 3D printer has been running non stop for over a week crunching out parts to me to test fit.  I think I'm about ready to lay some fiberglass and reinstall the baffles that I removed.  Here are a few pics of the process so far.

New Oil cooler sitting in the old mount location.  Notice that the support arms are about 2" too short.  

A little better picture of the oil cooler.

Not as much room under the cooler for an exit duct so I will have to rethink the heating air inlet again.
One of the 3D printed inlet ducts that I created as a test.  This one did not fit well so I have another one designed and on the printer that is a bit shorter and has a little different angle to the inlet ring.

Here is the new back baffle configuration.  Still a bit of work to do including a little primer and paint but this is a much better location for getting cool air for the oil cooler.

This is the outlet duct I created.  The bend on the corner was way too large so I had to redesign this one as well.
