Well at any rate I have a 12/4 pitch roof, pretty shallow really.

Now all I gots to do is make the cuts and put the support struts in.

I'm pretty close to stabilizing that punching bag. Putting down plywood
duckboards along the ceiling joists stabilized the ceiling side to side -
good suggestion, now adding vertical stringers to the rafters will prevent
it from jumping up and down

Are roof angles necessarily standard? I ask because I'm going to be
working on the rafters and need to cut an angle piece to fit in beside the
2x8 holding up the roof.

I measured it out and came out with 9 inches over, 2.5 inches up which
should equal ~15.5 degrees for the roof angle. I'm not interested in
perfection, it just has to fit reasonably, but if I can get it exact it
sure would be nice. However 15.5 deg doesn't match a 3 in 12 or 4 in 12
pitch more like 3.5 in 12. That's why I'm asking if roof angles are
standard, or at least WERE standard in the 1960's.

Just for clarification, my attic is ridgepole construction, 2x8 supports
for the roof, every other truss has a 1/2 x 10 board connecting the 2x8
supports. Weird construction, doesn't look sturdy at all in my eyes.
