Meanwhile, back at the metal shop...

So, I'll walk through a part of this conversion from Reno racer back to stock. One of the biggest mods the race team did was to move the location of the oil coolers and the configuration of the inlet and wing structure. The stock air duct opening lets/forces inlet air to the oil coolers, the intake, and the intercooler. Oil cooler air is partitioned off from intake air and is controlled with an oil cooler outlet door on each wing. When the doors are completely closed, there is still an outlet slot for the cooler air.
These sections of the wing are sub-assemblies that are removable from the center section. There is an upper section and a lower section. The oil cooler and the vane assemblies are mounted to the upper section, the lower section would be more considered as service access, I think as the mounts to the vanes are camlocs.
So here is the stock opening as you most are aware. You can see the open oil cooler door. I apologize for not having proper credit for the photos but I mean no harm.

Here is how the vanes and cooler are hung.

Here is the opening on the project aircraft.



A section of the new lower skin has been removed and you can see the new duct going to the oil cooler now mounted on the leading edge of the main spar. Here you can see the new lower skin and the modified oil cooler mount bracket.

This is the mount plate for the cooler. The saddle brackets had been cut and modified to mount on the spar.

So, rather than make new saddles complete, we decided to cut them apart and rework what we can.


This is the stock rear cooler saddle mount.

This, the forward.

Pattern time.

Next comes the actual welding fixture and to make the original style saddle mounts again.
