I've got a question for you metallurgists. I'm doing some work on my airplane's engine (A-75) and have the cylinders apart. I sandblasted a couple of the valve springs today to remove baked on carbon...it really isn't necessary as it is a very thin layer and doesn't affect anything, but they look clean when they are done. Anyway, I started wondering if I could have affected the fatigue strength (fatigue limit?) of the spring via superficial work hardening, increased surface roughness or something else that I know nothing about.The surface of the springs doesn't appear pitted to the naked eye, but it does have a clean but dull finish created by the sandblasting, so the surface roughness has been increased. I know it may be impossible to say without having any definite facts (type of steel, actual change to surface, etc.), but anyway, what is your best guess? Would you say this likely would, would not, or might affect the fatigue strength of a valve spring?Thanks for any input!Steve RuseNorman, OK ________________________________________________________________________________Subject: Pietenpol-List: TGWP on Encore

I hate to be commenting on my own lame post, but I just wanted to say... perhapsI judged TGWP too hastily. I actually sat up until 1:00 or 1:30 to watch theentire movie again, and it really isn't too bad. I'm not a huge Redford fan,but aside from his poor acting (settle down everyone [Rolling Eyes] ), therewere a lot of details that I missed in the first couple of passes. Perhapsit has something to do with watching it real late when the kiddo isn't distractingme every 30 seconds? Anyway... I still haven't memorized my lines, but I will pop it in again soon forsome background noise in the shop, and to take a closer look at all the airplanes.--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 17 Aug 2009 12:35:22 -0500Subject: Re: Pietenpol-List: Re: Sandblasting valve springs...a mistake?

Ok, let me commit some heresy here. I just didn't think that TGWP was all thatgreat. Its an aviation movie which makes it fun to watch but I never felt fanaticalabout it. On the other hand, I thought High Road to China with Tom Selleckwas excellent. In fact, I liked Selleck's character O'Malley so much ,I named my dog after him. O'Malley spends his time out in the shop with thePietenpol and so far he hasn't desecrated the project, so I take that as a goodsign. All right, you can start flaming........PaulThe Pietenpol is slow, but the earth is patient.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Don:I've looked for a direct address for you, or some way I could contact you personally,but I'm unable to find anything. Anyhow, I just want to say thank youfor taking my son (Tyler) for a ride at Brodhead. He is still telling peopleabout that, and I know he will remember it forever. We had a super time up thereand are already looking forward to next year. My wife (Theresa) and son wereboth lucky enough to get rides (thanks Bill Rewey and Jim Markle for coordinating)...I would like to thank Bill again personally, but I don't think heis on the boards and I don't know how to contact him either. I know that thoserides definitely made a difference in my family's overall interest in my project.Oh, they were both already pretty involved in the whole thing, but theBrodhead trip and the rides were very exciting for both of them.I posted a couple of video clips after Brodhead, which you may have already watched,but I'll post them here again anyway.

Wow! What an awesome shot! I love it! That is what flying the Pietenpol is allabout! Thanks Bill!How about this. I talked to your son before the flight about things he could andcouldn't do. I didn't want him to get scared so I told him to just sit straightin the seat and told him what not to touch. I figured he would be likemany other kids I've given rides to where they just kind of sit straight and areobviously nervous. As soon as we broke ground his arms went out flailing aroundand they never came back in until we were on the ground. I could actuallyhear him up there yelling for much of the flight! Pointing at other airplanes,pointing at stuff on the ground. He was obviously pretty excited. Thatmade the flight much more fun for me!

I spent 11 weeks in England working on Flyboys, 35 hours of flying and lots oftaxiing on the ground, and figure I might have 2 minutes on screen. Everythingabove 500 feet was CGI, I guess the low stuff around the trees was too hardto do. And there were some things in the script I wish they'd changed, but itwas a blast doing it, the people were great, and it paid well (Imagine gettingpaid to fly around down valleys and between trees). I hate to see it criticizedbecause I know how much work went into it, but I understand the criticisms.And it was independantly financed, so they had to squeeze a $100 mil movieinto a $60 mil budget.As for other movies, "Always" is good, it has airplanes, and my girlfriend cried,so what more can you ask for?Also, do not miss "Dark Blue World", trust me.-Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 19 Aug 2009 00:50:33 -0500Subject: Re: Pietenpol-List: Re: TGWP on Encore

Look at the photo again... there is another triangle (pointer) on the inside ring(just to the right of zero). Also, on the inside of the altitude markings(0, 5, 10, 15) there are other markings that read 20, 25, 30, 35 respectively.Those might have something to do with the barometric pressure, right? I mean,they are in the right range... perhaps the outer is an incremental measurement?What a cool instrument.--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

> Just where does one find one ball bearing? Gary,All items, except the baby oil were obtained from ACE Aeromotive (ACE Hardware).The ball bearing was in the section of fasteners where there are rows of drawerswith screws, bolts, springs and such. Get the plastic tube first and then picka bearing size that fits well and a couple of short bolts that lightly threadinto the ends. A small piece of brass is all thats needed but if you cantfind any, look for a door kick-plate itll give your shop a supply of brass formany projects.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Interesting Altimeter [was: Re: skid ball]
