Received the new bulkhead bars from Van’s. Cut and deburred them. Scuffed them, Machine countersunk and riveted them. Reamed all the holes and bolted them to the aft bulkhead.

Finished the forward and aft center section bulkheads

Riveted the cover ribs to the forward center section bulkhead. Added the AN3 bolts, nuts, and washers and torqued them down.

 

Secured the bearing bracket braces to the bearing brackets with screws, washers, and nuts. The riveted them to the bulkhead and opposing ribs.

Continued assembling the mid-fuselage bulkheads

I was using the squeezer to do some dimpling and riveting.  About halfway through it started leaking air from the valve. I disassembled the valve and found that the o-ring that prevents the poppet from-over extending had sheared in two. I called Cleaveland Tool and they were more than happy to ship a new o-ring at no charge. Nice folks over there. In the meantime I’ll be using the DRDT-2 and C-frame dimpling duties and shooting all the rivets with the gun.

 

I assembled the bulkhead bars. Unfortunately I screwed up one of them and had to order a new part from Van’s. Here’s the good one…

I moved on the the aft center section bulkhead. I machine countersunk all the holes then riveted the nut plates in place. Then I riveted the side angles to the bulkhead.

 

I countersunk and riveted the bearing brackets.

 

I dimpled the cover ribs and riveted the nut plates in place. I riveted the bearing brackets to the ribs as well.

 

Machine countersunk the bearing bracket braces and riveted on the attach angles.

 

Moved on to the forward center section bulkhead. I machine countersunk the holes on the flanges and riveted on the nut plates. Then riveted and bolted the side angles in place.

Primed all of the parts.

Dimpled the bulkhead and side channels.

 

Riveted the doubles to the bulkhead.

 

Riveted the side channels and doublers to the bulkhead. Unfortunately I didn’t see the note in the instructions indicating that the manufactured heads should be on the aft side until after I had driven all the rivets. So I got to drill them all out and do them again. Yay.

 

All’s well that ends well.

Cut the parts that needed to be separated on the band saw.

 

Deburred all the edges and scuffed the parts.

Ready for priming. Plans call for reaming several off the holes to .311″. I didn’t have a .311 reamer so ordered that from McMaster. Should have it by next weekend’s build session.
