They do look good. They look awfully thin to me. Maybe it's just the angle the picture was made or the camera or maybe the fact that I built my ribs from the GN-1 rib profile. I think It's a bit thicker than the Pietenpol rib -- but not that much. The main difference is in the nose shape. I read somewhere that the thicker nose would give a little better climb. Don't know that to be true -- I haven't gotten to that stage yet. That Stewart System looks great. My only experience is with Ceconite and the Randolph dope process -- I will go with Stewart's glue and house paint -- if I ever get that far.

I just used it mainly because I wanted to. and I like how crazy simple it is to repair. It's toxic, it stinks, it burns, it ain't that cheap, but other than that; it's great! In all seriousness though, I liked the nostalgia and that it was easy to repair and it is proven to last a LONG time. I'd probably use Stewarts if I was to do it again.

I just really like to work with it. Very easy to repair. Fun to spray. I tried Poly Fiber a while back but everything since then has been dope. Just used to it I guess. Probably the best reason for using dope though, was when my son, in second grade, went to school and told his teacher that he and his Dad were "doing dope in the garage last night..." The phone call was priceless. Also, there is something about the look of hand rubbed dope that is very difficult to replace with any other system.

(GRC-RXD0)[Vantage Partners, LLC]" Subject: Pietenpol-List: dope Great story Don! I too used Randolph dope on my Pietenpol for several reasons over polyurethane based systems, two being that it is lighter and also it is much easier to repair and blend in if damaged.

You should find the cause. Is there a helicoil tab or cracked plug insulator? It can be caused by improper leaning where you stay at the peak or slightly rich of peak for too long. Do you have a CHT and/or EGT gauge?

Did you verify each cylinder for proper size before assembly? I wouldn't guess it, but machine shops regularly get that sort of thing wrong. A good friend of mine was the editor of Hot Rod magazine at the time he rebuilt a Camaro engine for me. He sent the block off for machining and when it came back, he checked the crank bearings and found some off tolerance. Had to send it back a couple times before he was happy. He was the editor of a national car magazine, if there's ANY customer you'd want to do a good job for (and it was a well known performance shop in LA), you'd think it would be him. I just assumed when you send something like that out, it would be right. He said that was pretty normal... For a really good engine build, you have to verify all that stuff yourself he always told me. Doesn't usually result in catastrophic failure, but will easily affect how long the rebuild is good for. Wouldn't have to be too much too small to cause that... Perhaps something as simple as that cylinder wasn't honed as much as the others. Maybe ring gap too small? Would heat that cylinder up a lot more, with corresponding piston swell. Nice to know what happened in any event.

I know mine was burned by detonation, and looked nothing like that. It looks like friction heat due to ??? wrong bore for that size piston, rings??. Did it lock up on you and quit, or did it start running rough then quit? I will look again and see if anything comes to mind. See the attached pictures of the piston I blew up during ou growing pains. Eventually found that a helicoiled spark plug hole caused ours, it was very intermitent, and would run fine and out of nowhere start loosing power (detionation). Send me a picture of the cylinder wall and head if you can.
