Fly Bridge question on Hatteras 42 LRC

[PierreR]

I recently purchased a 42 LRC and the starboard side cabin door is binding and scraping on the cabin side. Upon really looking at it, the only explanation is that the fly bridge has dropped about 1/8" to 3/16". Enough to bind the door.
My guess is that there was a gasket under the fly bridge and that gasket has deteriorated to the point on being gone on the starboard side and going on the port side.
Can anyone confirm that this is the case and does anyone know the thickness and material for that gasket?
I am tempted to raise the fly bridge a couple of inches, clean it out and put in a 3/16" silicone rubber gasket. If that is too thick the doors might be sloppy in their tracks when I am done.
A very recent post suggests the fly bridge may not be as heavy as I thought it was and this might be a fairly easy tedious job.
Any help would be appreciated.

Pull the door first and look at the hardware on the top and bottom. If its like the other Hatteras sliding doors of that era, it has rollers top and bottom with springs on the top rollers. The flybridge has no gasket. It was set in 5200 and screwed to the cabin top. I doubt it has sagged.

Sam's Marine has all the parts you need to rebuild the door. Also take a look at the bottom track. Has that pushed up somehow? The door is wood so it could have warped. All possibilities and all can be addressed when you get it off. Plane some off of it if necessary to get it to fit right.

The track system at the outboard top is jammed against the underside of the fly bridge, rolled inward and broke the teak at the top. The track then dropped about an 1/8". Unless the bottom somehow swelled and came up, (No evidence of this that I can see) the only explanation I can think of is that the fly bridge dropped.
Why would Hatteras bond the fly bridge down with 5200 when the fly bridge is designed to be removed for shipping the boat down the road. The 42 LRC is small enough to truck.
Forgot to add that I lived in Ludington for 13 years.

The reference to the weight of the flybridge was only regarding the console, not the whole roof.

My fly bridge is little more than the console, it does not have a hard top, only a light bimini.

Hatteras kept 3M in business with their prolific use of 5200

The Graving plan in the Hatteras owner's manual lists removing the fly bridge to get the shipping height down from 17'1" to 13'6" on the cradle dimensions listed. I did not think it was possible to remove something bonded with 5200. There are screws every 4" and I see no evidence of 5200. If it has 5200 under it, I likely cannot remove it. One way to find out is to start and one end and remove enough of the screws to see if it will lift and what is under it. If it does not budge, I will not pry hard per your mention of 5200.
I can always trim the edge of the door frame at a 45 deg angle to gain some clearance for the top of the frame to the fly bridge underside. The top trim piece on the frame matches the side trim at the top but is rolled in about 3/16" at the bottom of the top trim and does not match at that point. At present the top of the frame is crushed.
The door rolls okay but hits the cabin side. the port door seems to be developing the same issue but at present rolls easy and does not hit yet.
I am presently 1.000 miles from my boat so I cannot take pictures. I can do that next week and figure out how to post them here.
A good friend of mine is good friends with Lyle who also has an Egg 42 at your same marina. Hopefully the rain gods will let me bring my boat back up the Ten Tom, Mississippi and the Illinois into Lake Michigan Next spring. From there I would definitely be headed up the west coast of Michigan.

I removed all of the screws and found some of the 5200 was holding like it should, I drove some felling wedges in and cut the good 5200 with a saw.

But, half of it was much less tenacious and just peeled off.

That said, what I am referring to as the flybridge sets atop the cabin top and had no intersection with anything except for the cabin top.

I would think that there are definitely better remedies than messing with the flybridge, take some pics and maybe someone will have a better idea of the situation.

Got back to the boat and restudied the problem. Took off the outer frame and determined that the bottom rail is where it should be and the fly bridge had settled. Took the screws out of the fly bridge to cabin top joint and there was essentially nothing in the joint but some dirt. The fly bridge lifted easily with some wood wedges. Now there is room for the top door rail frame and the door works nicely.
I am going to seal the joint with and appropriate shim and 3M 4200

It would be nice if you could add some pictures to this, because I suspect that like myself, others can not picture what is happening.
