Oil Sump Prototyping Part 3

Yesterday, I continued work on the sump and made 3 fuel probes.  One for pPod and two for Toan’s plane.  It is surprisingly fast to make them.  Now if I could only get Princeton (the electronic’s part) to finish modifying their system so I can use the probes I’ll be set!

Today, I almost finished the sump.  I want to ship it off tomorrow.  The last piece of the puzzle was the mixture control arm.  I am using a bell crank which is mounted on the shaft of the throttle butterfly.  It is mounted to a bearing so each control (throttle and mixture) can move independently even thought they are on the same shaft.  Getting the clearances and ensuring it is easy to make for a production enviroment was critical.  I designed the arm in Acad then made about six of them adjusting the size, length and angles a little at a time until an optimum combination was found.

 The last thing to do is to mount everything, pipe all the fitting to ensure no interferences and ship it off…
