The plans call for platenuts on the underside of the seat rib to secure the center bearing block. I'm wondering why they don't use a simple nut, bolt and washer. I'm thinking of just bringing the bolt up from the underside and putting the washer and nyloc nut on the top. Seems like a lot of effort to install platenuts for not very much gain. What have others done here ? __g__ ========================================================== Gerry Filby gerf@gerf.com Tel: 415 203 9177 ________________________________ Message 2 _____________________________________ Time: 11:15:25 AM PST US From: Jim Streit Subject: Re: RV9-List: Flap actuator center bearing block mounting --> RV9-List message posted by: Jim Streit Gerry, If you do as you propose, how will you get a wrench on the bolt to tighten the nyloc nut on the top side of the bearing block. Nut plates are very easy to install (you only have to install them 1 time) and you don't have to get on both ends of the bolt to tighten. There is No need to get on the other side of the baggage floor to get access to the bolt head. I installed nut plates on all of the seat and baggage floor ribs to make it easy to remove the floor panels for annual inspections...

If you can't get a wrench on top of the bearing block to tighten a nut, how can you do so to tighten down the bolt into the platenut ? If I understand you right, you've changed all the LP-4 rivets called out for the baggage floors in favor of nutlplates and screws ? Why do you need to remove the baggage floors for inspection ? The only thing to inspect is the pushrod assembly that runs through the tunnel - and that I have used platenuts/screws per the drawings.

How will you keep the bolt from turning when the floors are already in place preventing access to the bolt. I installed platenuts rather than rivets so that I could inspect under the seat and baggage floor to check for corrosion. I am not talking about the center channel which already has nut plates giving you access. Gerry Filby wrote: >--> RV9-List message posted by: Gerry Filby > > >Hmm.

I did read the drawings right]. The bearing block is bolted through this rib flange and the floor. So you have access to the bolt head from inside the control rod tunnel which has a removable cover. This is the same access you would use to rivet on the nutplates since the instructions have you rivet through the floor and rib after the floor is installed. I have already gone with the blind rivets, per the drawings, for the baggage floors and they are already in place. I admit that its a nice idea to be able to remove the floors, but I'm past that stage already and I made sure to Akzo prime the bottom skin and the ribs, so I'm not overly concerned about corrosion in this area. Having said that, if I did this again I would replace those skins with a slightly heavier gauge sheet - they are real flimsy. g > > --> RV9-List message posted by: Jim Streit > > Gerry, If the bolt is coming up through the rib from under the baggage > floor, when you start to tighten the nut, the bolt will turn.

The rib flange is toward the (center) tunnel. It has been a long time since I worked on the center section of the fuse and I was thinking the flange was towards the outside. I live in South Fla and with the high humidity and living so close to the ocean, corrosion is a big problem . That is why I made all of the floors removable buy using nut plates.
