I had a few more holes to debur on the firewall, so I took care of that and set it aside for later.
A couple non standard things I did.
1) I did dimple one hole in the side skin at the rear spar opening that others have done to avoid a reported interference
2) For some reason I drilled six holes too big on each side (#30 instead of #40). Not sure why I did this. These are the holes that strap the center section to the longeron
