Back in 2019 I was helping a friend extend a house and he needed a hand with the trusses
we had about 8 trusses to fit to extend the roof line.
however after fitting the first one we soon discovered they were the incorrect angle and height at the top.

he was a little pissed off to say the least.

So I set about doing some measurements and using greek calcs found the trusses should have been
A. a  height of  1225
B. a bottom cord of 3770 x 2  and,
C. and the top cords an angle of 18 deg and length of 3964 x 2 .

What we had was
A. a height of 1010
B. a bottom cord of 3770 x2 , and
C.   and the top cords an angle of 15 deg and length of 3903 x 2
so resulting in
A. being 215 mm too short
B. No change and,
C. 62 mm too short.
The correct Trusses were re manufactured and surprisingly nobody accepted responsibility for the error and the builder had to carry the cost  believed to be in the area of AUD$1000s

advance forward to Sep 2024 some 5 years later and I have a call from my friend saying he was going to dispose of the incorrect trusses he had been  "lumbered" with  and did I want them, being a skinflint and enjoying recycling timber I gladly accepted.
So they arrived.

Good thing I am single eh!

Standby for more "interesting" information on the RWRT Part 2, ... and beyond!
