6-21-05: My new worktable! I painted it blue so aluminum would photograph well on it. 6-27-05: My new bending brake! This will see lots of use now that I am starting my fuselage. 6-29-05: Here are my standard L angles in progress. On the left are the pre-bent strips; on the right are the finished L angles. 7-03-05: Laying out the forming blocks for the Firewall. 8-16-05: Working on Center Spar. After bending the two center spar web pieces, I clamped them together and drilled the holes for the caps.

8-16-05: Drilling spar webs and caps 1/4 inch for spar spacers. 8-16-05: The Center Spar Spacers I fabbed last week in place. 8-16-05: Here you can see the space left for the wing spars and the AN4-15A bolts sticking up in the background. Today I started drilling holes in my fuselage bottom skin. See next frame. ---------> I ran into a problem. Click here to see the H.T Frame saga.

10-16-05: Made new (wider) HT Frame. New dimension is 222mm.  10-16-05: These Z angles are tuff to make. The mod on my brake limits how far around I can bend. Top bend is 60 degrees on the inside w/ 1/8th inch Rad. 10-17-05: Here is the Rear Bottom Skin before drilling for L and Z angles. 10-17-05: Drilling some holes in some angle 10-18-05: Here's where I am at the end of Fall-Break . . .Back to class, less time for plane :(

12-29-05 (Christmas Break) : I'm back in the shop, making some headway.  Here's why I'm having a hard time getting anything done. My dog Samantha wants me to throw the Frisbee. 12-29-05: Pilot drilled lower rudder attachments and spacers. Next 6 photos updated 6-4-06: I've been back in the shop a couple of weeks now and made a lot of progress. Here is the outside (bottom) of the bottom fuselage showing one-half of the lower rudder hinge.

Inside of the bottom fuselage. It's yellow because it is sprayed with Zinc Oxide primer for corrosion protection. Outside of bottom fuselage mostly riveted together. Fuselage access opening (for inspection purposes). This will have a hinged door. Close-up of nutplates. These are riveted in to allow the door to be held on by a machine type screw (aviation grade) Me holding the rudder up to the fuselage. Starting to look like something more than scrap-metal.

Here you can get an idea of the curvature of the rear fuselage top. I could not resist clamping the stabilizer into place to see how it will look.

The 3 photos below, show some of the progress made during my summer break I managed to get quite a bit done--though I didn't stop to photograph much along the way. I'll add more photos soon. I have a bit more done than is represented here. For one thing, the firewall is much further along than pictured. I spent a great deal of time working on the main wing spars (the main structural support for the wings). This is an important part of the plane--and one that doesn't show a lot of progress quickly. I have to finish the right and left wing spars, before I can do much more to the fuselage-- because once the center spar is riveted into the fuselage the process of setting up the wing dihedral would be difficult.
