Working on the seat

Well I have not posted in a while, but there has been a lot going on. We have been trying to make the controls. The problem with this is that because we are moving the seat back about 3" I am worried how this will affect the controls. This is why I want to finalize the cabin area. This starts with seats. We widened the cabin to 42". This is 2" wider than the stock plans. I figured since there will be 2 more inches in the cabin that I would make each seat 1" wider. I also made it 3" longer. I hope it all works out. We shall see.

Firewall pulled in

This is the btm tube of the firewall. We have made our fuse 42". This makes our firewall dim 41" as apposed to 39". We used a bar clamp to pull the btm longerons into place. Dad did a good job of fitting this tube and for some reason when it got tacked into place there was a gap. You can see it in the pic above. Not a big deal, it will fill, just annoying.

Seat front spar

This is where the front of the seat will rest. We will have to smash the top edge of the tube to match the btm of the door jam.

Tall Boy modification

This x-member is supposed to intersect at the main intersection. We have tacked our x-member 3" back per a conversation with Earl Luce. We tacked it lightly because it might get moved.

Tail spring attach cross member

This is the tail spring attach x-member. It is ovalized 3/4 .035 tubing. We smashed it cold.

We would have put in the tail post & horizontal stabilizer spar but for some reason do not have the correct tubing.

Pulling tail together

This is looking back from the firewall. At this point all but 1 crossmember aft of the cabin are installed. The last piece will be put in when the tail spring is installed.

Big head!

Bringing the tail together took some work. We worked our way back 1 section at a time. At each station we would put the x-members in first, square that up then put in the diagonal. We would then put in the top and btm diagonals, all the while trying to keep it square and on center line. The problem with this is, as you work your way to the tail the frame gets real strong and its hard to get it where you want it. The curves in the longerons make things worse. In the end we think we got it where we want it. There might be an advantage in starting with the tail tacked together and working towards the firewall.
