But like you say, they can still vibrate and weaken over time causing failure. Later this morning, I will post two photos of my spinner failure on my web site. I will be willing to bet that after seeing these photos, those with press fit front spinner bulkheads will get them screwed down. Another must is to inspect the spinner for cracks prior to every flight.

I think mine got damaged during the hurricanes when the spinner took that hit, but the crack took 24 hours of flight time to show itself. By then it had cracked almost all the way around, but was hidden by the prop until the day the prop was actually making contact with the nose of the cowling.

If you measured your prop thickness correctly, and they built the spinner and bulkhead correctly, you should get a "press fit" between the spinner and the front bulkhead when you install the spinner.

I looked at your pictures http://mywebpage.netscape.com/n886mj/photo.html and it appears to me(opinion) that the crack originated at the cutout for the prop. It is important that netters understand that when cutouts are made in aluminum, that localized areas of stress developed in the sharp freshly cut aluminum. Care must be taken to relieve that stress by rounding and polishing the edges in the area where the cuts were made. If this is not done, cracking from the stress area will developed rapidly. I have never purchased an expensive spinner, and have never ordered one where I could request different sizes to accommodate differences in prop thickness. Although I have lost one, it was because of backplate failure. I have had a second backplate crack as well. I agree with inspection requirements of both the spinner and backplate. In 20 years I have never had a fwd bulkhead. Another important issue is keeping the alignment between the backplate and the dome. if the screw attach holes are not drilled correctly, the spinner will wobble, which is an out of balance condition. The worse the wobble, the more vibration and the more likely and rapid a failure will be. My screws are NAS1032 and I use floating nutplates on the back of the backplate. Screws will gall the spinner. Most production aircraft use a plastic washer under the head of the screws.

With the thickness of the teflon tape, the front bulkhead fits very snug inside the spinner. The teflon tape prevents any abradement of the aluminum, so the fit doesn't wear or change. It's not necessarily the right or wrong way to do it. It's just a different way of accomplishing the same thing. -Jeff -- larry flesner wrote: >I did not know they were supposed to be installed by just stuffing them >in there.

The distance is adjusted using shims between the moulding and the unit such that there is a firm press fit at the flange needed to make the bolt holes align on the back plate. There are no bolts on the front bulkhead as such. Balance and central alignment are critical. Using a torch inside a composite spinner can help in getting the bulkhead correctly positioned because the composite is opaque.

I cracked 3 spinners over 200 hours on my KR without a front bulkhead. (Ok, it takes me awhile sometimes to learn....) On the 4th spinner, I added the front bulkhead bolted to the front of the prop, no bolts thru the spinner to the front bulkhead but I did use a foam tape to take up the potential slop between the bulkhead and the spinner. It is only bolted at the rear bulkhead. It has worked fine for the last 200 hours.

Heath - Columbia, SC -------Original Message------- I ran a single piece of teflon tape around the front bulkhead to prevent chafing and to ensure that it was a snug fit. The contributing factor to this event was the lack of a front bulkhead spinner. Do not fly without one. when you install the front bulkhead, install some threaded screws with nutplates to secure it. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to KRnet-leave@mylist.net please see other KRnet info at http://www.krnet.org/info.html _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to KRnet-leave@mylist.net please see other KRnet info at http://www.krnet.org/info.html ------------------------------ Message: 21 Date: Wed, 30 Mar 2005 21:25:12 -0600 (CST) From: blindate@seark.net Subject: KR> Re: KR spinner bulkhead To: krnet@mylist.net Message-ID: <1167.66.138.162.66.1112239512.squirrel@www.seark.net> Content-Type: text/plain;charset=iso-8859-1 Installed a fiberglass spinner on the Avid/VW.After 2 hours there was galling inside the spinner at the forward bulk.A slight vibration was noted at high rpm.Shimmed with tape and no vibration,no galling.Every preflight inspection includes prop and spinner.Screws optional.Fly Safe Tommy W. ------------------------------ _______________________________________________ See KRnet list details at http://www.krnet.org/instructions.html End of KRnet Digest, Vol 347, Issue 130 *************************************** ================================== ABC Amber Outlook Converter v4.20 Trial version ==================================
