Here is how the pvc is joined to the 2 by 6 at the bottom the second clamp
This is how to attach the poly panels to the pvc using the wooden strips
and screws made for poly panels
A view of the main span down the top.
This gives some idea of the end. I used 3/4 inch square strips, got
them real wet with hot water bent the
wood and screwed from the backside of the pvc pipe to give a frame to attach
the end. If you look at the
right upper side of the picture you can see 2 holes caused by a hailstorm!
I have about 10 holes to fix.
Another ceiling view showing the second set of ribs. there is 5 ft
of pvc from the top to this rib and 5 ft
this rib to the 2 by 6 on the bottom.
This show where I overlapped the sections of poly on a rib.
This is in the large greenhouse but shows how the 2 by 8 is attached to
the blocks after having a countersunk
hole drilled into it.
