I know it's been out of print for a long time but, what an expose about the politics of "History". Get it if you can!

Taking the bottom of the front wing spar as a reference and using the face of the spar as vertical and perpendicular to the reference, if you keep the faces of both spars parallel to each other it seems that the bottom of the aft spar is about 3/16" higher than reference to maintain the airfoil profile given. I need to go back to Mike Cuy's video and photos to take a look at his wing construction and jigging, but when laying out the wings, does that mean that the aft spar is jigged about 3/16" higher than the front spar when the ribs are slid on? The ribs are constructed with the spar slots parallel to each other and if the spars are jigged with their bottom edges at the same level, the ribs would have to deform slightly to keep the spars parallel. One other, minor issue- the original plans show the fuel tank in the center section to be about 10 gal. but in CAD it doesn't seem to have that much volume. Has anyone built a tank to the profile shown in the plans and checked the volume? Oscar Zuniga (keeping my political views to myself, but everyone is entitled to my opinion!)

It fits nicely in the spot and it is exactly 10 gals. this is with me not counting on my tank top being perfect, so I ran about 1/2" under the top contour. A top layer of very thin aluminum (Home Depot) was added on top for final contour. Even could have squeezed some more out of the size if I needed. walt ----- Original Message ----- From: "Oscar Zuniga" Subject: Pietenpol-List: spar/rib jigging > --> Pietenpol-List message posted by: "Oscar Zuniga" > > Hello, Pieters- > > In looking at the wing cross-section in CAD and with the supplied full-scale > rib drawing from Mr. Pietenpol, I'm missing something.

It holds 15 Gal with 1 quart unusable. That was for a float type gas gauge.

Installed my brakes. I purchased Grove Aircraft wheels and brakes. Got them from AS&S for about $600. If you are not aware of Grove wheels and brakes, they are pretty much Cleveland Clones. Magnesium wheels and machined aluminum dual piston calipers and .25" thick steel discs. Overkill for a Piet I guess, but they are gonna keep my Air Camper stopped while I do full power run-ups from a 110hp Corvair! All I need to do now to complete the brake system is run lines from the calipers to the brake cylinders.... a fairly simple task (nothing's ever "fairly simple" huh?!) Some of you have been asking for recent pics.... sorry. I promise by Wednesday I will have them up on my site.... pics of the fuselage combing and brakes.
