Notching Steel Tube at Complex Intersections

I started nothing at the aft end and worked forward.  When I came to the big 7/8" diameter crossmembers, I encountered what I call my first "complex" intersection -- where two tubes came together at the longeron.   I wasn't sure how to handle it, then I found a help video on the EAA web site which demonstrated a technique where you make a paper template, and use that to mark the cross-member where it needs to be cut.

In this case, the crossmember on the right was straightforward to notch.  Then I made a paper template for the left.  Once I had the paper template where it fit against the right crossmember and longeron properly, I used the paper template to mark the left crossmember with a Sharpie.  Then I cut the left cross member using a Dremel tool and angle grinder.
   
Notice how radical the left crossmember notch is.
   
From another angle.
   
Just by itself.
   
But both crossmembers fit against each other and the longeron real nice.
   
The forward 7/8" diameter longerons transition to 3/4" diameter just aft of the cockpit area.  The 3/4" tube slides right into the 7/8" tube.  But per the plans, you have to splice the 7/8" tube with a 30 degree cut 45 degrees off the veritical.  To do that, I made another paper template, then used that to mark the 7/8" tube, then cut the tube using the Dremel tool and angle grinder.
   
Here is the result:  both the forward top and bottom longerons.
