I was able to get main spar number 1 put back together and start putting rivets in. I did not set any of the rivets yet. I only put rivets in to see what sizes I would need to order. Looks like my calculations of length were off and I will have to order some different sizes. It does look good though. I also discovered that the primer in the holes caused the holes to be to small. I used #21 size bits and wish I would have used a #20. I had to run the bit in and out of every hole to get it to open up enough for the rivets to go in.
