I have two problems after drilling the firewall brackets (sigh).
Problem #1 - pure carelessness by me... the lower left edge of the firewall is 1/16" further back than it should've been. The others are all correct. Root cause of this problem is I missed the centerline of lower angle bracket when I drilled it on the left side.
My options are:
1. order another lower weldment bracket, drill out old one, put new one in (at this point I have only drilled the outside 2 holes on the angle bracket on firewall.
2. live with 1/16", and shim corresponding engine bracket with 0.060"?
Problem #2 - on the lower right weldment - the aft hole edge distance is 0.225 which is slightly less than the required .25". Edge distance is fine on the 713 longeron. the problem is in the weldment. what's puzzling me on this one is I don't see how I have any control on where this hole is - it is positioned by hole in skin and position of weldment.
Any advice on either of these is appreciated.
