Have you met with John M. yet? Both are good welders. Bring some of your most recent test pieces to the next chapter meeting and we will give them a look over. Russ and I would like to come to your shop sometime and check out your progress over the summer. Good luck, -------- David Gallagher Zodiac 601 XL-B: flying, 280+ hours now Next project under construction: Finish my father's Aircamper Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454684#454684 ________________________________ Message 2 _____________________________________ Time: 12:59:43 PM PST US From: "Ralph" Subject: Pietenpol-List: turnbuckles Early on in my Piet build I bought a large number of used turnbuckles at Oshkosh. A couple years ago I took one of the end forks with me to Oshkosh to be sure and get the correct size pins for the fork end. Now that I am assembling the tail pieces I find I have misplaced the fork end to one of the turnbuckles. I located a supple of used turnbuckles locally but can=99t find one of the same thread pitch. I found one of the same diameter but only about 4 threads will fit into the barrel. Under a microscope I count 30 threads per inch on the type fork I need to replace. The used one I found has 32 threads per inch as does the forks available from Aircraft Spruce. Is it possible the used turnbuckles I got years ago at Oshkosh are a military spec which is different than the thread spec currently used on civilian aircraft? I will be able to replace the entire turnbuckle unit but I am curious about the 2 threads per inch difference in the forks. Anybody have any explanation?

I've heard some of the older sets threads varie d. It was important to keep them together as matched sets...

Anyway, I was looking at the master cylinder for my son's crf 450 Honda dirt bike, and boy it sure looks like something a person could make toe brakes out of by mounting to the diagonals, similar to how many have done, just in this case the master cylinder would be mounted stationary instead of having a pivot mount on the end. Anyone ever tried this? -------- Jon Jones Ironton, MO Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454706#454706 Attachments: http://forums.matronics.com//files/20160407_150625_108.jpg ________________________________ Message 5 _____________________________________ Time: 07:32:43 PM PST US Subject: Pietenpol-List: Re: off topic 1920's project book From: "Ryan Mueller" Hi Jon, It appears you may have some iteration of "Every Boy's Hobby Annual". This site has a number of articles scanned in from various yearly publications of the Annual: http://www.easybuiltmodels.com/nostalgia.htm This article from the 1928 issue in particular matches--at least in basic content--the pictures you posted: http://www.easybuiltmodels.com/spSimple%20Model%20Aeroplanes.pdf The layout does not match, however. My guess would be that this article was published in more than one issue of the Annual--maybe not every year, but reused multiple times at least. In my searching I am seeing issues from 1927 - 1936; unfortunately I'm not finding specific information to indicate which year your copy may be from. I don't really have any more information about this publication beyond what is provided on the website above--this is my first encounter with it. I presume this was a UK publication; when searching for issues on Abebooks, an online bookseller, 41 out of 55 copies for sale are from UK vendors. Hope that helps, -Ryan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454711#454711 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
