Lots accomplished since the last post ~13 days ago - see below for details. Most importantly (not shown here), I've ordered the engine, prop, firewall forward kit, put a deposit down on a SteinAir panel, started talks with Abby at Flightline Interiors, and ordered a crapload of materials from Aircraft Spruce for the fiberglass work (esp. the canopy transition). However, for the past couple of weeks, I specifically accomplished the following:
- installed idler arms; drilled, primed and assembled elevator pushrods and stick link pushrod
- riveted center section of forward top skin to fuselage structure (back-riveted as much as possible with my wife bucking); first time under the panel section - pain in the back; installed bushings into hinge ribs; primed and painted canopy cradles
- a half hour to torque ONE nut/bolt to attach control arm to fwd elevator pushrod; fabricated elevator bellcrank assembly; trimmed and installed AP pitch servo bracket; installed bellcrank mount; installed mid elevator pushrod to bellcrank assembly; installed elevator pushrods to idler arms; checked match-drilling of Tosten control stick with stick bases
- Installed pitch servo
- greased and installed canopy cradle assemblies (4 difficult-to-reach bolts); attached gas springs to canopy cradle assemblies; installed canopy release mechanism and tested action (very nice); prosealed rest of top forward skin to fuselage; also, prosealed gaps in the firewall and subpanel, but instead of sealing from the inside, after placing a fay seal on the flanges and clecoing the skin, I sealed the remaining holes from the outside, pushing the sealant through the holes. Next proseal session, I may fillet seal from the inside as well (belt-and-suspenders, incase there is a small gap I couldn’t see)
- Final-drilled both Tosten control sticks; attached control stick bases; attached link stick pushrod; worked on control column travel to get both sides to hit stops at the same time; aligned control sticks
continued working on control column travel to get both sides to hit stops at the same time
riveted rest of top forward skin to fuselage; added final bead of sealant to subpanel and plugged any other holes with sealant, taking care to not make it too thick (may impede canopy)
- attached brace brackets to brace; riveted fwd and aft roll bar frame assemblies; clecoed roll bar frame assemblies, roll bar straps and window shims; #30 final-drilled outboard #40 holes
- #30 final-drilled inboard #40 holes; deburred holes; machine countersunk outbd roll bar strap where bar brace attaches; countersunk #30 holes in window shims; primed the inside of the frame assembly
Elevator pushrods (3) and stick link pushrod:
