I wanted to get the attach point of that rod as far forward as possible for a better and more advantageous angle. The way I see it, if it did rotate the total movement would be max. 1" (unless the bolt pulled out of the longeron). After the first 20 degrees of turning, it would come in contact with the rod end fitting?which would take some energy to twist. All in all I believe it would go a long way on holding back the shoulders of the front seat passenger in a crash. Then I guess there is always a weak link somewhere in every system. Most times (thank God) we never get to see what that is.?What stage are you at with your build? Dan Helsper Poplar Grove, IL P.S.? Now I remember why I did that. -----Original Message----- From: Ameet Savant Sent: Tue, 9 Jun 2009 10:15 pm Subject: Re: Pietenpol-List: front seat shoulder harness attach Dan, Novice question- In a sudden forward motion (as imparted in a crash) what is keeping this entire assembly from pivoting forward? The member shown in photo 18 and 24 seems to take on the job, but it is anchored to the fuselage using one bolt. Could that fitting pivot around the bolt inward?

It does have only limited movement. I am not building yet but I did buy my first airplane part and it is being delivered in just minutes from now. It is a corvair engine I bought on ebay. I don't know yet if it is the right serial numbers to convert, but if not, I got a really good deal on an engine that was running just a year ago and shouldn't have trouble selling it to the car folks. It seems to be right one at 110hp 1965, but you never know what mods have been made on it. I am so excited about that!

I know it kind of depends on fuselage type, wing construction, length, width, etc. I've looked over the plans and believe that I've figured it properly, but since I am hoping to get all the big stuff on my next order I would like to know how much ply others have required. I'm planning to build the long fuse, and if anything I may widen it a couple of inches. Not sure that is necessary at this point.

This can be an advantage. If you weld and bolt up the harness assy. first, and then build all the rest, you can make it all one piece as welded. But then the harness assy. a) is either in in your way as you run tubing, wires, cables, and mount instruments, put the ply pieces up, etc., or b) requires you to keep putting the mount in an out to see if things clear, and to get it out of the way.
