Fuselage Center Section #4

 More work on the center section tonight.  Match drilled the side bulkheads to the aft center bulkhead.

First you have to cleco the puzzle together.

I finally found a use for my wing nut cleco's I bought years ago.  I used these to pull everything together instead of the wood blocks and clamp spelled out in the KAI.  Worked great!

Match drilled the holes and put a cleco in each one as I went.  The cleco's won't grip the entire stack of parts so I alternated sides when inserting them.

Left side done.

Right side done.

Now I get to take it all apart and deburr the remaining edges and holes, prime the non anodized parts and then rivet it together.
