Front Floor Side Alignment
This seems a little weird. When match drilling, all was good and right. But now that I am installing the front floors, the outboard-most hole alignment is off (These are the holes on top of the joggle that attach to the channel which is in turn attached to the skin). The miss-alignment is off the same amount on both sides of the airplane. I can flex the skin/channel enough to get clecos in, but it seems to take a lot of force. Has anyone else encountered this?

My floors required quite a bit of force in that area, too. I'd cleco it up, take a look at the outside contour, and if good install those rivets!

The shape of the floor panel makes that impossible.

Thanks David. I'm glad to hear this. The contour does look OK after I get the clecos in place, but then I noticed a bit of oil-canning. Temporarily installing the forward fuselage rib (with clecos) does help with the oil-canning, but it's most definitely still there. Any oil-canning with you?

Hi Joe,
I don't have any noticeable oil canning in that area, but I didn't check for that before installing the ribs. I'd like to believe that riveting in your ribs (vs. just clecos) will stabilize everything nicely.

It's been too long since input those parts,together that I don't remember all the details. I do recall using a 4ft pipe clamp to pull things into alignment. What I can't recall if it was the floor or the outside skin that was my problem.

I too had that problem
I also remember having that problem. Maybe not quite as bad as yours but I do remember pushing on the side to get the clecos in.

Any oil-canning? Google tells me that others have had oil-canning in this area in the past. I wonder if this is why. What Google doesn't seem to know for sure is if those who have had oil-canning at this stage see it disappear as the build progresses. There were some suggestions that it would (or might) when top skin is in place and when engine is installed. I'm trying to figure out if I should install an additional stiffener. It'll be pretty easy to do now - not sure how easy later.

None
Don't have any oil canning (At least in the fuselage). I do have stick-on sound insulation in that area as well. (In case it has an effect)
