Very interesting. Thank you sir.
I imported the scan from the Assembly Manual into AutoCad, created a vertical line, came off the bottom of the vertical line with another matching the lean in the drawing and got 9 degrees .... so very close.
These pages in the manual appear to be copies of mechanical drawings, so they should be fairly accurate.
That puts me in the ball park, the mounts will flex enough to go plus or minus a couple of degrees.
Update: Just imported a high rez scan into AutoCad and scaled it to match perfectly (meaning for instance 6" shown on drawing, measures 6" in AutoCad) and came up with 9 degrees again ... jeez, can't believe you got that close holding a protractor up to your screen
Scaling these manual drawings into AutoCad seems to be a great way to get measurements that aren't listed ... I'd say accurate to about 1/16"
Did anyone else have to drill holes to mount their fan guard?
