JUST JIGGED THE SLELETON BUT WAS WONDERING HAS ANYBODY HAD TO SHIM THE F-404 TO GET THE 25 15/16 MEASUREMENT, TO THE POINT WHERE THE FLANGE IS BARELY TOUCHING THE LONGERON.

IS IT OK TO RIVET THE ENGINE MOUNTS TO THE FIREWALL BERFORE PLACING IT ON THE JIG.

ANY ADVICE ON THE FUSELAGE WOULD BE GREAT, WHERE TO DRILL 1ST OR LAST, WHERE TO SHIM OR NOT, I KNOW ALL MEASUREMENTS ARE IMPORTANT BUT ARE THERE PLACES WHERE THEY ARE NOT TOO CRITICAL.

THANKS

Your longerons should be touching all your bulkheads, you can shim between skins and bulkheads, however, but you shouldn't have to. I would say the point at which you are at is the most critical as far as how strait and level your airplane is going to fly making EVERY measurment while you have it upside down on the jig important. I don't remember what I did as far as the engine mounts go... I suppose if you set it up on the jig and rivet off, it should be fine.
