Yoke ball support modification

[vik]

Does anyone have instruction on modifying the pilot's yoke support to accept a 9-hole panel?

My understanding is that the triangle mount is turned around and the panel is trimmed to make a bit more clearance for the lower instrument just above the yoke shaft.

A picture or a drawing would be nice.

I didn't need to touch that piece at all on my 65' E, and neither did my friends 66' C.

If you look closely at the instrument panels…. The holes have a greater space directly over the yoke’s shaft…

Modifying a control mount would require an expensive STC, or selecting parts from a newer model of your plane…

Modify the panel… not the plane itself.

The shaft technically moves vertically as well as in and out…

Many newer avionics don’t bump into things like they used to…

post pics of what you are talking about…

That will clear things up a bit…

Best regards,

This is somebody's 9-hole panel. My understanding is that one has to modify the yoke attachment point to accommodate the instruments in this fashion.

In preparation for my dual GI-275s and Ei-CGR 30P & C, I installed my massive DG (that's about a foot long) directly about my yoke tube. No rubbing or modification to the yoke tube mount. My buddy's plane has dual G5s and same 9 hole panel.

Note that the VSI is above the yoke shaft instead of in the ‘standard’ position under the altimeter.  The DG is probably too long and would interfere if it were installed over the yoke shaft.  Successful installations (like gmonnig’s post above) raise the DG vertically in the panel for clearance.  

Replacing the pilot’s vintage ‘bent’ panel often incorporates longer standoffs at the top which improves the geometry.  LASAR had a kit for this (thanks Dan!).  

If this is a DIY project, making the panel out of plexiglass is useful to verify clearances before production of the panel in metal.  I had to recut my panel when my template for the Aspen flush mount bracket had inadequate clearance to the yoke ball mount.  My Dad used to call that, “Turning out scrap.”  So, don’t be me!
