While I was at it, I used the same basic brake design (a drum brake, inside the wire wheel, which I'm gonna cover this time round) except moved up from go-cart brakes to golf cart brakes, which are much better quality and larger, though I'm sure they still won't hold those big wheels. The only other thing I'm changing is my anti-rotation set up and changing to a travel limiting arched tube rather than a cable, as I've read about a cable swage giving way on one when someone's bungees broke. I'll try to get some photos this week, once I get the airbox back on the carb.

John, as Gary mentioned, the seats provide just about the only shear bracing in the entire fuselage (the firewall is the only other bracing). Mike Cuy made an access panel in his rear seatback, but as I recall he left the perimeter of the seatback intact and cut out an opening for access. Other people (myself included) have provided an access panel under the belly to allow access to the elevator bellcrank area. If you used enough screws to attach the seat back it would probably provide enough strength, but I found the rear seatback to be too far forward of the bellcrank to really allow easy access. I put the panel between the two bottom stringers that I added, spanning between the rear seat bulkhead and the next cross piece in the fuselage as shown in the picture below: This area is then covered with a sheet of .025" aluminum. A total of 18 screws hold the panel in place. It comes off every year for the Condition Inspection, to allow inspection and lubrication of the bellcrank area.

In doing the weight and balance calculations back home, I find that I'm close to the rear limit of 20" aft of the leading edge when my big butt is in the rear seat. I used the center of the rear seat as the CG of the occupant but I'm seeing that a more accurate location of the occupant's CG is under the navel, or in my case, an inch or so aft of the front of the seat bottom. If that's the case, I'm within the aft limit. Any thoughts on this or am I just avoiding the fact that I really need to lose a few lbs myself?

Thin steel wouldn't add much weight, and might re less prone to harden and crack? I don't mind a little extra weight on the nose anyhow.

The pilot's belt buckle is the accepted cg location of the pilot. Mine is a bit aft of 20" aft of the LE. I'm at 34% of chord, or about 20.4" aft of the LE, and it flies just fine.

There I am, all that time ago, becoming consternated myself thinking, "OK, just what pulleys can I use then?" Including phenolic ones that looked just like the ones in the plans! So I said "The hell with it!" And was going to order the things anyway after returning from Arlington that year. As luck would have it I came back with all the pulleys in the plane and a couple extra for good measure! But they are all 3". If you're concerned though, take a look at that front pulley on the stick. That ain't no 15!! Something tells me you're right. It's probably that hairpin thing. Clif > Right. We can check with the A&Ps but I'm willing to bet it has nothing > to do with the pulleys. > Kevin "Axel" Purtee ________________________________ Message 39 ____________________________________ Time: 08:35:10 PM PST US From: TOM MICHELLE BRANT Subject: Pietenpol-List: cloth used for Fiberglass fuel tank Anyone make their tank from fiberglass?
