I would like to do a bit of speculation and make some suggestions if I may. Must stress that I do not have any experience with airplane component balancing but do have lots of industrial experience on especially things like fans and other rotors. If no obvious defects in the engine can be found please check the prop flange and bolts. Have a mag-particle test (or any other NDT) done on the hub/flange. Special attention to the key-way if you have one. It is usually the first place to fail under load but has the uncanny way of closing up again as soon as the load is removed. Can be checked using a strobe with the engine running without the spinner and cowl in place so as to see the actual prop-hub in motion. Not sure about your setup, N/A if you have a taper mount on the crank, as it would have departed long ago if that was the case! Do you have a retaining bolt for the flange at the front of the crank? You would possibly have seen fretting and/or wear on the crank under the hub/flange if it was loose! Did you remove the prop-flange? I take it there were no indications on the flange, bolts and/or prop of chafing, indicating looseness?! Is the prop a plain laminated wood with a clear see-through finish or has it got some kind of reinforcing cover that can not be seen through? The reason asking is that there could be a lamination problem that also only shows under load. I suggest that you borrow a prop that is known to run smoothly and install it on your plane if the roughness continues after the engine rebuild and all other things have been checked. Please do all the testing on the ground and don't go flying until 100% sure that all is ok. Would hate not to see the interesting flight reports any more!! Best regards and good-luck with the fault finding.

Also if it is a solid axis or it takes central hole. What kind of steel is used habitually and if somebody has used some automobile part. Thank you ------------------------------ Message: 3 Date: Sat, 16 Apr 2005 00:52:21 -0400 From: "Colin & Bev Rainey" Subject: KR> Axle To: "KRnet" Message-ID: <005d01c54240$1366ede0$c7432141@RaineyDay> Content-Type: text/plain; charset="iso-8859-1" Eduardo Richard Finch reports how several builders have used the common 9 inch Ford station wagon or truck axle with success. It is bi-metal so it will flex with loads instead of breaking, is rated for far more than the prop stress, and has its own bearing assembly that is bolted on to the outer plate of the PSRU. Have a machine shop spline the axle to match the top gear, and taper the end to go in the seat of the support bearing on the rear of the shaft, again Finch mentions use of the larger inner bearing of the front spindle assembly from the same vehicle in a custom housing made to allow the bearing race to be tapped into it, and then the bearing installed from the inside of the 2 plates, with a solid backing plate, and an axle seal on the inside that the axle passes through, and seats in the bearing. Pictures and more details are available in the book by Richard Finch, Converting Auto Engines for Experimental Aircraft AS&S, Wicks, and Sportys all carry his book. crainey1@cfl.rr.com http://kr-builder.org/Colin/index.html KR2(td) N96TA Sanford, FL Apex Lending, Inc. 407-323-6960 (p) 407-557-3260 (f) crainey@apexlending.com ------------------------------ Message: 4 Date: Fri, 15 Apr 2005 22:27:59 -0700 From: "Steve Glover" Subject: RE: KR> Correction on Crank To: "KRnet" Message-ID: Content-Type: text/plain; charset="US-ASCII" If no obvious defects in the engine can be found please check the prop flange and bolts. ---------------------------------------------------------------------------- -- We didn't mag the hub but the runout was only .002 on the bench. On the plane is was more like .009, which is what led us to believe the crank was bk. I just don't think we had a good read on the plane. I am starting to think it may be a prop problem. I am hoping to know more tomorrow.

I didn't like the way it looks and fits so I called Todd's canopies and ordered a new canopy. anyone want to buy a RR canopy --- cheep?

I wish I were! Just thought I would let you guys know I made a 2.3 hour flight today. The longest flight yet. Exhilarating!!!!! That gives me 9.7 total flight hours on my KR.

It's gotten to be tradition. I'm adding the KR Gathering to my list of traditions this year. My assumption is that you will surely be at Oshkosh am I correct in this. Do you know if they have a KR dinner and get together as well. I'd like to meet some of the people I'm chatting with.

However, I doubt I will fly the KR there. It is still in primer and I seriously doubt it will be finished by then. I will however be flying to the KR Gathering, painted or not. There is usually a scheduled forum once during AirVenture. This was hosted by Langford last year and he is doing it this year. This is the only KR get together at AirVenture that I know of. Two years ago, Jeanette Rand hosted a lunch buffet catered in. Very nice I might add.

You should see all the RV's at Sun 'n Fun without even primer. They're just bare aluminum with bare fiberglass wing tips, etc. They come anyway.

It consists of this. Mixture full rich. All switches ON. Pump the throttle TWO times leaving it in almost full throttle ...just a small crack . Hit the starter button or key and VOOOOOOOM every time . I have been very sick lately and did not run the engine in over two years. I went out to the airport yesterday and on the first shot VOOOOM I sure have a lot to thank the guy that shared that little bit of knowledge. pass it on..Bill Starrs ------------------------------ _______________________________________________ See KRnet list details at http://www.krnet.org/instructions.html End of KRnet Digest, Vol 347, Issue 150 *************************************** ================================== ABC Amber Outlook Converter v4.20 Trial version ==================================
