9/21/98; 4.0 hrs; construction of canopy frame.

9/25/98; 2.5 hrs; pretty much finished assembly of canopy frame; fabricated hinge mount points.

The canopy frame takes a lot of tweaking. I had to cut the tubular brace so the hinge brackets would line up properly. Short lengths of tubing were telescoped into the brace to lengthen it as necessary.


More tweaking will be necessary. I am now ready to rivet the frame together, then assemble the jettison mechanism.

9/27/98; 2.0 hrs; riveted canopy frame.

9/28/98; 2.25 hrs; fabricated and riveted angle to instrument panel.





Here is the proposed panel layout (as of today...). Printout is from Panel Planner software.

The two large black dots in the lower center of the panel are the air vents. The vertical card compass may be replaced with a conventional wet compass.




Here is the screen capture from Panel Planner:

10/1/98; 2.75 hrs; completed canopy jettison mechanism.


fuse-105.jpg (30963 bytes)


I decided not to build the complete canopy jettison mechanism because I have no intentions of blowing the canopy in flight (I even wonder if it is possible!). The mechanism is valuable, however, as a quick way to remove the canopy for maintenance. Consequently, I deleted the jettison handle that is supposed to protrude though the panel into the cabin.

To remove the canopy, I will need to reach under the sub-panel, remove a safety pin, and turn the mechanism. A 1/4" bolt was placed on the "handle" to serve as a limit stop so the canopy pins could not be withdrawn completely from the mounting blocks. Note also the custom-made bracket that will hold the safety pin for the handle.

10/3/98; 5.5 hrs; drilled, dimpled, and trimmed forward top fuse skin; mounted fuse on gear!


fuse-107.jpg (52622 bytes)


A come-along was hung from ceiling joists so the fuse could be hoisted to allow mounting gear legs. The legs fit very easily once I removed the paint from the mounting bosses.

There are a few pivotal points in the construction of an airplane; Setting the plane on its legs is one of them.

I found out very quickly, however, that it is going to be harder to work inside the cabin now.



10/5/98; 2.0 hrs; drilled forward canopy skin.

10/7/98; 1.75 hrs; trimmed and dimpled forward canopy skin.

10/11/98; 2.0 hrs; drilled, countersunk, dimpled canopy side skins; trimmed canopy forward skin.

10/13/98; 4.5 hrs; fabricated and installed gas lift strut mounts; installed manual aileron trim system.


fuse-109.jpg (43465 bytes)


Here is the control protion of the trim system. I used single-ear platenuts instead of the double-ear nut s supplied due to the limited space available for mounting.





fuse-110.jpg (41397 bytes)


This is the completed system. Trim is achieved via spring pre-load on the aileron torque arms. The springs are very light so they won't add stiffness to the aileron controls.


Note: I wasn't happy with the way the springs were attached to the links on the control tubes: The original configuration could promote premature wear of the ends of the springs due to friction when the controls were moved side-to-side. I made S-hooks out of stainless welding rod and used the hooks to attach the springs to the rods. Since the hooks are free to rotate, no wear will occur on the springs.


10/18/98; 2.0 hrs; installed cabin air vent inlets.

Remainder of canopy construction is in the Finish Section.
