How to best attach the top of a partition to the roof? I need to add on in my coach as the previous owner had the shower door do double duty. I've got a general idea but looking for alternate opinions. The ceiling is finished in naugahyde, so I'll need to carefully cut it also. It is a Tejas coach conversion from Pipe Creek Texas.
How wide is the partition? If it's not too wide, how about using aluminum channel that the partition will fit inside? I'm going to use 3/4" inside-width 6063 channel 1/16" thick to attach my 3/4" plywood walls to the floor, side walls and ceiling. 6063 can be bent without buckling the sides - 6061 cannot be bent this way!

Depending on the width of the partition and what it's attaching to, you might be able to use a Kreg pocket screw jig. I did that on the walls I've installed so far, and it works quite well with 3/4 plywood wall and screwing into plywood floor or ceiling. You can trim to hide the pocket screws if desired, or use plugs made for filling the pockets.
Otherwise I like the channel idea offered above, or use angle iron on one side.
6063 is about half the strength of 6061 -- that may make a difference.
How difficult is it to remove the ceiling covering? If that is possible, your options increase.
Probably not difficult for installer. I am thinking of carefully measuring twice, cut slit in Naugahyde. Use aluminum channel modified to match curve of roof in that area and attach to roof with shavehead rivets. Slide 3/4 inch oak veneer partition into channel and secure with hex headed screws into predrilled pilot holes and maybe also use Gorilla glue.

If you bend thin-wall 6063 channel, the sides will ripple unless you make a simple jig to hold them flat while you bend it. Obviously, the shorter the side walls, the easier it is to bend. I made my jig from two lengths of flat bar with a bolt between them - on the bolt is a stack of washers that squeeze the channel's side walls as you bend it, preventing them from rippling and buckling. It's not fancy, but it works fine, and I can easily bend the channel to exactly fit the compound curves of my ceiling.

John,I'm having trouble picturing that, any chance of a picture?
