I am going to cut grooves on the back side of the plywood to make it flexible to create the transition..
Think this through..I think I have made a mess..maybe you shouldn't be listening to all this..I may have screwed up in a big way
Quote from: RockwoodMike on April 11, 2024, 10:51 AMI used 2x3 Kiln dried wood because all the 2x4 wood was not kiln dried..heavy with water..Besides, you are looking for a small taper in the roof to create runoff..
So my 2x3 has a total height of 2.5 inches in the middle and taper to 1.25 at the edges..Add 1/4 inch exterior grade plywood on top of that and you have 1.5 total thickness at the edge..
That 1.5 thickness is the same as the original roof..That can match the wall to reattach (staples, screws) the wall to the roof..
Now here is the problem with all this and I am dealing with it right now..
That taper that you are creating has to go flat again at the very front of the motorhome..The front "eyebrow" look at leading edge of the roof is flat..
How to go from a taper to a flat area is going to be something I will tackle soon..(Next week)
If you are saying the interior is in good shape, I would carefully peel the aluminum off..little pieces at a time..Then carefully remove the flat foam..little pieces at a time..
Thus leaving the 1/8th plywood that is the interior ceiling..
Create your roof rafters..stuff insulation between the rafters..top with 1/4 ply..and then roll on a rubber or other type of glue on roll roofing that you see all new and white..
I placed my rafters 16 on center..1/4 exterior ply..All glued and screwed..
Quote from: RockwoodMike on April 10, 2024, 11:46 PMMy motorhome was a total disaster..Leaks..rot..mold..everything..The roof had caved in, thus wrecking the cabinets..everything..
I gutted the interior..That is when I discovered that there is no solid frame work to this..
thin paneling for the interior..foam..then an aluminum skin..all held together with glue..
Picture shows my first attempt..after ripping the roof off, I glued these 1x4s to the top edge of the wall..then built the roof as shown..
Then I moved to the walls..right at the point where the wall attaches to the floor is a 2x4..screwed into the floor..mine was totally rotted..It was just rotted dust..
the walls had no frame work..just foam..So right now the roof is being held up with stilts ..And I am making stud(2x2) walls to replace the foam only walls..
I took the original roof of in 3 foot section..just cut it with a skill(circular) saw..At the top edge of the wall, the roof wraps over the wall edge and has 10 billion staples that must be removed..
Some of the cabinets were screwed into the ceiling..But that wasn't a problem for me because the cabinets and everything else were removed..
So I just cut the roof in sections and threw them off to the side..
So after building the roof, then I discovered the walls were just foam and rot..
