Fuselage center section #62 - Firewall hinges!

 Finished up this section with the firewall hinges.


The KAI's have you make two mirror image hinges.  These are cut from the 6' length of piano hinge in the kit.  You must pay attention to the tab location  and cut two mirror image pieces.  Save their mates as they will be used on the cowl.  Be careful here to triple check everything before you cut or you will waste hinge stock!  Then they have you cut two shims out of a long strip of 0.020 included in the kit.


Then they have you mark and drill an alignment hole in the hinge and the shim.

Then you clamp the hinge to the firewall.  Be careful to align the hinge with the firewall and the side skin as called out in the plans.  Clamp well with side grip cleco's while drilling.  Cleco each hole as you go and keep checking the dimensions.


Then the parts are taken apart and deburred and then riveted.

Other side done!

That's the end of the section!

Yah!

On to the rollbar section!
