Chris,I must have spent an hour (at least) just looking at center sections and occassionallygetting distracted and looking at other construction photos. That's agreat collection you put together. My wife was the only reason it didn't goon longer.Thanks for putting that together. It's a great resource for the rest of us!--------Glenn ThomasN?????http://www.flyingwood.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 8 Feb 2007 07:04:40 -0800 (PST)

Gus,All bolts should be AN type with self locking nutsNylon insert type nut for non moving parts.Castle nuts with cotter pin where the bolt acts as a hinge pin or in hightemperature areas (under the cowling)No regular nuts should be used.On the VW conversion:Since you did not indicate that it has flown with the VW, I stronglyrecommend to do a Weight and Balance first !The VW should be considerably lighter.I personally doubt the VW is a strong enough engine for the Pietenpol, butI leave that up to you.Most importantly it needs to be a balanced plane.As it is an experimental Airplane there is no need to get an AI involved.An A&P can do the AI's job.However when a different engine is installed you do have to go through thefly-off period againThis applies when you swap the C 65 with a VWit does not apply if you swap a C 65 with another C 65Fly off period for a automotive engine powered aircraft is 40 hours with acertified aircraft engine it is 25 hours.Within that 40 hours no passengers are allowed and all flights can notextend beyond a 20 mile radius of home field.20 miles is typical, you can negotiate more with the FAA.You will have to notify the FAA that engines have been replaced unless theprevious owner did that.As a general statement as this is your first experimental, I recommend youcontact a local EAA tech counselor and let them have a look at it.The EAA tech counselors are volunteers and it is free of charge (OK, maybesome coffee and donuts)Hans gus notti To Sent by: pietenpol-list(at)matronics.com owner-pietenpol-l cc ist-server@matron ics.com Subject Pietenpol-List: Several ?? on this Pietenpol I just bought. 02/08/2007 09:04 AM Please respond to pietenpol-list@ma tronics.com Hello all,OK I have a few questions on how the steel bellcranks are attached to thewood.Less start with the rudder bellcrank, (I can take pictures next week ifneeded), The bellcrank for the rudder is lose due to the 2 small bolts thathold it to the wood ( the wood running from the top of the rudder to thebottom up front) on the rudder came loose after only 25 hours of flying.

The rudder is built solid, so I'm not concerned about that.2).

Hi Gus...The rudder horn should have three bolts. There should be a steel piece aproxamately 5/8" wide that is welded into the back edge of the rudder horn and bolted into the center spar of the rudder with one bolt. I can see that if it is not there there would be alot of twisting force on the front two bolts and a risk of wringing the leading edge out of the rudder. That's if I'm understanding what your trying to say of course.
