Wing hardware

 We have been working on getting all the hardware mounted on the wings.  On the left is an original wing bolt from a Jenny.  Notice the bolt head.  It is rounded underneath.  On the right is a standard AN5 bolt.  See the difference?


 Here is a typical strut hold down plate.  See the countersunk hole for the bolt? Because of the wing camber, these special bolts become self aligning.  Ever try to put a flat head bolt on a curved surface?


So you have two options when restoring a Jenny:
 - machine new bolts with the proper heads
- use spherical washers under modern bolts.


We chose the spherical washers.

You can get these washers from McMaster-Carr.  They are 18-8 Stainless Steel Self Aligning Washers, Male Half, 5/16in Screw Size ... so says the catalog. The Part Number is 91944A106.




Here is how they fit in the strut plates. The washers come too thick from McMaster Carr, so you have to machine them down a bit.

One completed plate on the wing!


We hope to have all the wing hardware installed this weekend.  The truck will arrive Tuesday night or Wednesday depending on the weather.  Then it is final assembly time!

See you June 1st


Enjoy

Brian
