Notching the rivet holes in the Almost a 14 mod - 2 hours

 One of the items that's a bit of a head scratch-er for me was figuring out how the rivets should work on the Almost a 14 mod where it connects to the longeron. The you-tube instruction video notes that the rivets are to be ground down so the end cap sits flush with the underside of the longeron. I don't like the idea of grinding down rivets, so I chose to install the required rivets, however I will notch the end caps to fit around the rivets.

First I need to open up the rivet holes to the size/diameter of a shop rivet head.

I can now cut openings in the end cap rivet holes so the end caps will slip into place with the longeron rivets in-tact. 

Yup, this will work well.
