Simple Bat Wing Pivots

<< < (3/3)

Tallon:
Is he even working on his car anymore it seems he stopped posting progress awhile ago

No Bull:
Let me see if Jeff will send me his CAD drawing for the exact placement of the bolts that go through the bearings on the underside of the frames on the wings.  I know he had to play with this a little and eventually got it right.  The gaps look nice and the wing tucks under a little like an OEM wing does.  Here is a video that I posted in another thread that shows the wings in action:

If you need more pictures or measurements, let me know and I'll grab them while I'm at his shop.

Murci-Me:
Wont there be a problem once the frame is mounted to the wing though? Once in place, the wing has less than 1/4" forward or backward space in order to slide it out of these pivots. The thickness of those pivots look to be about 1/2" thick, plus the extra thread sticking out to apply the nut. You would need at least a 3/4" gap between the leading edge of the batwing and the surface it lines up with.

Here is a rudimentary video highlighting some simple but very effective bat wing pivots (sorry ahead of time for the poor quality). 

This design uses a couple custom brackets that can be made from scrap metal and a couple male threaded rod bearings.  Some nice features of this design is the smooth and very strong pivot that can be adjusted up and down by adjusting the threaded ends of the bearings.  Because the bearing is a "ball and cup" design, there should never be any binding in the pivot action and it can be easily greased.  Removing and installing the wings just involves taking the lock nuts off of the bolts that run through the bearings and sliding the wings forward and out of the bearings.

Let me know how this works out for you if you decide to reapply it.

Thanks,

Chris
