My VA146 bearing that was back ordered finally arrived, so I fitted it to the rear spar with bpp411 and app411. Match drilled the holes, scuffed and primed the bearing. Finally got to try the SEM EZ Color primer. Turned out very nice. I then set my first rivets ever on 24JL. The plans/directions state that 4-5 rivets are indeed the correct size, although they looked and were too short, I went with Vans specific call out here assuming them had a reason to specifically say that 4-5 was the correct size. I have seen some use 4-6 with good results. They rivets did seem to squeeze a touch flat, but again, I assume there is a reason for this call out, nor have I seen a reported issue or SB for the 4-5 call out . So wth.
