Onto the Elevator...

It has been too long since building.  Lots of other projects, work, and trips getting in the way.  

The wing kit is all safely tucked away in the basement - and getting that crate apart turned into a multi day effort - WOW.

The below pic is the elevator forward spar with the doublers clamped in place.


Pilot holes drilled for the doublers.



All doublers drilled.



All ribs, and partial ribs clecoed in place.



Center rib (A and B) doublers ready for drilling.



The centre section needs to be squared up before drilling the partial aft spar (where the trim tab goes).



Bottom right skin clamped in place ready for drilling.



Control horns drilled.  Still need to trim off the excess on the aluminum angle.



Bottom right skin drilled.  The clamping method I devised is working fine for the elevator, but will NOT work when I flip it over to drill the top skins.  I am going to try something similar, but with 2" blocks instead of 0.75".



Trim tab pushrod slot cut in left hand skin.  Once the pilot and main holes were drilled, I put 2 pieces of 3/4" plywood under each side of the slot and then clamped it to the work bench.  This gave me a relatively steady skin for dremmeling and filing.



Left hand skin in place, ready to drill.



Left hand skin drilled!



Left hand skin has a corresponding slot cut in it (using right hand skin slot as template).  Also, control horn attach angles are drilled into the spar, ribs and doublers.


Next will be modifying the table and clamping method to be able to flip the elevator upside down - but leave the clecos in place AND ensure it is level and without twist.  Fingers crossed...
