Roof, roof! (and other bits of progress)

 OK, it _still_ a really bad dad joke, but that's where we are. The roof is more or less installed.  There are
some spots that I need to go back and countersink screws - edge grain of plywood has slightly better zero holding power, especially for staples.  And there were a couple of interesting 'learnings' - like the fact that the point at which a 5 foot sheet lands on the inside of a frame is very different from where it lands on the outside - didn't take that into account...

The last was fairly easy to address - the end of the panel was in a relatively flat spot and right in the middle between frames, so I added a 1/2 inch doubler and screwed both sheets into that - worked just fine.  I also used Weldwood III instead of my normal II in order to gain a little more work time - we've gone from too cold to nearly too warm in the matter of a week.  



The other project of the week has been the hatch.  I'm still not convinced it's right, but I'm going to run with it for the moment.  There are a few 'fit and finish items that I think might be improved upon.  BTW, you can see the green 'lunch counter' through the hatch.

The hatch is seven 3/4'' ACX ply ribs with basswood stringers, a 4¨ oak top plate, and a 3/4¨ oak sill plate. The former will provide strength for the hinge, and the sill plate should be strong enough to latch through.  

The sides will go on this week, weather permitting.  My plan is to position the side, add a few screws for a 'ledge, and then roll on a good coat of contact cement - press it on and pressure roll it into place.

Hindsight is [almost] always 20/20...

 As I've said before, this trailer has been a very agile project.  There have been more than a few compromises, changes, and adjustments...
