Well, I've finally actually started doing something constructive on my Piet Project! I am working on the rib jig, and have the template laid out, and all my blocks cut and drilled. At the risk of bothering those who may have already seen this discussed over and over, I'm gonna raise the issue again. In laying out my jig, I noticed the area where the top of the rear spar and the top capstrip meet there should be a tiny wedge, but on the template, the spar is shown with a slight bevel. I think some folks make up the rib and just remove some capstrip to make it fit the squared spar, but I was wondering about just pushing the rear spar down enough to make room for the wedge, thus moving the lower strip down the same amount. I haven't measured it all out, but I get the feeling that the lower capstrip may have not been positioned correctly on the template, so It seems as though this would all work out. Gordon: It sounds as though about all that's needed for the ListBot service then, is someone to get the thing setup and then it pretty much runs on autopilot? I guess I could do that, I'm sure I'll be around for a LONG time, heck it's gonna take enough time just to get the rib jig together! If it's low, and I mean LOW maintenance, then it wouldn't be too much of a hassle, I guess......Gary Meadows________________________________________________________________________________

Hey Joe, I see what you mean, I thought about actually taking the plan measurments and laying out the rib using that, but man that looks like work! I think some of the folks were just notching the underside of the rib and sliding it onto the square-edge spar. I guess there's more than one way to skin a cat, (or a Piet)! I imagine that it probably isn't going to make any real difference how you do it, I can't imagine it making much difference in the performance/strength of the plane, your way sounds fine to me! It is odd why the template would be different from the plans, though... Have you started your project yet? I found a piece of 3/4 Birch plywood that was leftover from a store remodelling near Kuykendahl and 1960, and so I'm using that. Thanks for the info.

I laid out the rib and the spar using the dimensions in the 1933 plansandthe spar is still an interference fit in the rib. I have the CAD fileifanyone wants it. I plan on using a plotter to do a full size ribtemplate.Marc Davis-----------------------------------------------------Hey Joe,I see what you mean, I thought about actually taking the planmeasurmentsand laying out the rib using that, but man that looks like work!
