Tim,

 

I used the factory glass spinner.  Having heard several stories of this
spinner cracking the back plate, I figured it must have been to a slight
out of balance or alignment situation.  Aligning this spinner is pretty
much impossible.  Misalignment will cause a vibration that leads to
failure.

 

My solution was to build a foam and 2-bid/side "donut" that is glassed
into the nose end of the spinner.  I laid 2-bid on either side of 1/2"
foam and cut it out into a donut shape approximately the size needed
with the inside hole just a little bigger than the diameter of the prop
hub.  Then micro/BID the donut into place in the nose of the spinner.
Finally, I put release tape around the prop hub, routed out the foam for
about 1/4" on the inside hole of the donut to form a channel, filled the
channel with micro and slid the entire spinner in to place and mounted
it (the screws had already been installed). 

 

The next day the spinner popped off and I now have a custom fit bulkhead
that will prevent wobble at the tip of the spinner, thereby preventing
cracking.

 

For photos, check out http://www.lancaironline.net/pix/olsen and look
under the "construction" album for photos of the finished product.

 

Hope this helps.  Let me know if you have any questions about this.

 

Dan
