Some of you may know form my previous questions, I have been building
a large ‘barn style’ outbuilding, one half is an open car port, other
is to have a pair of doors fitted.
Roof is currently being tiled, in the next couple of weeks I want to
build a pair of softwood ‘garage’ doors.
Height is 2085 (82”) and width 3302 (130”) for the pair ..~ 1650
Been getting my original thoughts together … as per this sketch:
Basically an outer frame which is rebated to take a tongue & groove
‘infill’, I would make my own t&g using full length loose tongue
splines, all well glued to each other, and into outer frame.
I would horizontal brace (on inside) at hinge handing points, and fit
a diagonal strut between the braces for racking strength … as per this
My initial thoughts on sizes of timber to use, and how to do it are in
the drawing http://tinyurl.com/5o83zd
Be interested in views on sizes of timbers, in particular the top/
bottom rails and the side stiles, joints etc.
Also not sure if cross brace should strut against horizontal support &
verticals as shown, or horizontal only as I have seen in some
carpentry books. See: http://tinyurl.com/6fescs
Also no real idea yet on how to joint in the horizontal braces ...
seen dowels suggested in one book, other option I suppose could be a
half lap joint ?
A couple of observations about the design, the inner splined panel can't be
glued to the
outer stiles, natural expansion and contraction would tear the doors apart.
Even though the bracing looks good in the drawings, I think they are much
too close together
to keep the doord from racking. You could build the doors and line the back
inch plywood, that would keep them from ever sagging. This would also solve
of attaching the horizontal bracing as it would be mostly cosmetic.
