Wingtip attach angles

[Bradrock]

I read a while back about the arrangement of attach angles on the end of the main spar, but can't seem to track it down.

Can someone shed light on attach angles for the tip rib on the spars please?

Sheet 2 shows them on the front of each spar.

You're right - so much detail hiding in plain view in these plans! Thanks.
