Re: 1988 Imperial 280sf engine swap and restoration (pics)
Hi jb, thanks for your imput. In hindsight, I realize in my haste to get the glass done, i skipped a few steps i had originally planned, like the knee wall bracing and guide wires. Its a pretty simple design tho, so redoing it isnt all that bad. While investigating what failed, it appears it was a gap in the plastic that I patched in, and on the windward gable end to boot!, thats where the problem started. Lacking a ridge beam, once the pvc was compromised, it was all over, with 2 days of wind.
I did notice that a few of the cross fittings cracked, even tho they werent glued, also some dimensional lumber split, tho is was partially due to the weight falling upon itself.
The purpose of the osb isnt structural, but practical, as in, it will elimiante any weak spots in the enclosure, especially on the wind gable end. The plastic will be over the entire enclosure, including the osb.
I also pounded in some cut up 1 inch galvannized pipe, flanking the 4x4 bases, and will clamp them to cure the movement problem....
I was really pleased to be able to glass in comfort, so im gonna give it another go...
