You
But that still doesn't add up to me.
last 11.5” is only the shorter edge. The point on the long end would stick out another half inch.
The cut pieces not counting the scrap could be laid out and both top and bottom planes would be 48” but the total length would still be 48.5”
Am i missing something?
PS. shop grade scribble diagram is not drawn to scale.
Good catch - you're right. When I wrote the post I mixed up the trim and base numbers and gave wrong dimensions.
The frame has two parts. One made from .75 x 1.5 lumber and the other from .5 x 1.5 lumber -
The
trim is four pieces of .5 x 1.5 x 12.5
on the INSIDE (13.5 on the outside)- with the 45 degree angle cut along the
.5 side.
The
base is four pieces of .75 x 1.5 x 12.5
on the OUTSIDE (9.5 on the inside) with 45 degree cut along the
1.5 side.
So the short side of the trim is attached to the long side of the base - the 12.5 sides - to make the frame.
- the trim took
52" of .5 x 1.5 lumber (13.5 + 12.5 + 13.5 + 12.5 )
and the base took
44" of .75 x 1.5 lumber (12.5 +9.5 + 12.5 + 9.5)
so when I finished cutting the
base I mistakenly thought, hmmm.. four pieces at 12.5 each - should of took more than one 48" long strip

?? Later when I wrote the post I mixed up the base and trim dimensions -
my bad -
