Next, the FWD and AFT Roll Bar Assemblies were clecoed to the F-01231D Roll Bar Bases to be match-drilled. There are lots of holes to match-drill in this location also. Because of all the clecos holding the assembly together, you will have to use a 6” or 12” drill bit. The plans suggest using a 12” bit, but I used a 6” inch bit and it worked out just fine…..gives you a little more control when you’re drilling (either will work - just your preference). This picture shows the outside of the right (copilot) side…..
…..and the inside of the right (copilot) side.
This is the outside of the left (pilot) side…..
…..and the inside left (pilot) side.
The next two pictures show the F-01432A Roll Bar Brace Assembly clecoed to the F-01475 Top Skin and the F-01406C Bulkhead. (The left and right brackets were previously riveted to the Roll Bar Brace Assembly).
Here is the other end of the Assembly clecoed to the FWD and AFT Roll Bar Assemblies. (Additionally, here are a few of the 426 rivets used on the FWD Roll Bar Assembly and the CS4-4 rivets used on the Window Shims and AFT Roll Bar Assembly).
