Hi folks,I've hunted around but so far no luck. Does anyone know if and where I could scama CAD file for a Continental A-65 or A-75? I don't need great detail, but thebasic views that will give me footprint, mounting points, prop hub locationetc.. IOW what you would need to design an engine mount and sketch a cowl around.Thanks!Mike--------Piet-builder-who-hopes-to-be-flying-next-summerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

While it is true that the strength of a laminated wooden structural member is always limited by the strength of the wood itself, the likelihood of having hidden defects is appreciably reduced when smaller sections are glued together. Ergo, a laminated member can be stronger than a one-piece solid one.Also, select pieces can be placed at the top and bottom of a wing spar, or beam, where the stress is greatest and lesser quality material can be placed in between. My 1946 Taylorcraft had laminated spars and this is exactly what they did in those days when so many lightplanes were being built. In addition, there were beautifully-done scarf joints (without doublers!) indicating the use of precision machinery.I don't own that T'Craft anymore, but 62 years later it still has the same spars with the factory splices. A testimonial to laminating and perfect glue joints, to be sure.On my Pietenpol I used Douglas Fir for the wing spars, duplicating the original I - beam section by laminating 1/4 inch flange strips to a full-depth web that is 1/2 inch thick. "Swallow tail" filler blocks were used at fitting locations. There are no splices. Perhaps I could have reduced the cross section size to take into account the greater strength of DF (as compared to spruce) in order to save some weight, but I didn't. Even so, my Piet is lighter than some at 630# dry empty weight.BHP told me that he laminated the spars of the last airplanes he built. I think he used Western Hemlock strips to make a rectangular cross section. The only disadvantage of laminating, as I see it, is the extra work involved.Graham Hansen Pietenpol CF-AUN ________________________________________________________________________________Subject: Pietenpol-List: Re: Continental engine drawing file

I just looked through my resource files and located the 3-views of the small Continentals.One of the few times that Bingelis let me down... he doesn't have3-views of the Continentals that we want. However, Evans does have a rudimentary3-view with key dimensions in his "Lightplane Designer's Handbook".I would be happy to scan that one to a .jpg and upload it to my website and willdo so in the morning when I get time. I trust that Mr. Evans will not mindme putting it out on my site, particularly since I would encourage anyone topurchase his fine manual... it is a close second to Bingelis' books in utilityand chock-full of useful information of every sort.Being from the old school, I had much rather look at hand-drawn line illustrationsthan all the CAD drawings in the world. Another reason why I so enjoyed purchasingBill Rewey's packet of tips and ideas that he publishes for sale; theyare all hand-drawn. They all make great armchair reading and thinking material.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

Rob,How about a PDF file?I just took the Autocad file of the C90 Grover posted, and converted it toPDF.Unfortunately there weren't any dimensions on the Autocad drawing, so I'mnot sure what use this will be.Anyway, here it is...Bill C. _____

I believe that the study you are referring to was in one of the wood workingmagazines. I believe it was Mark Langford that posted a copy of the articleor a link to it. I am up to my neck right now and can't look for it, but itmight be found on www.krnet.org.Oscar, do you still have that email somewhere handy?Brian KrautEngineering Alternatives, Inc.www.engalt.com-----Original Message-----

I've scanned the dimensioned 3-view drawing of the small Continental engine from Evans' manual to a .jpg and it can be viewed here: http://www.flysquirrel.net/piets/3view.jpg . If you want to snag it, just right-click on the image and 'save as'.I once again recommend Evans' book as being well worth the money, and in fact if you purchase Volksplane plans from him, he will throw in the designer's manual for free.

Hi,It's been quite a while since I posted anything to the list, largely because my project is dormant while I search for a better job. Anyway, I've used both Gorilla Glue and the Elmer's equivalent in a number of (non-aircraft) applications over the years & I think it has good potential for some aircraft applications if you use it correctly. I did some bond tests several years ago & got wood failure before glue failure every time if I used the following procedures:- Used a freshly-opened bottle of glue (no more than 2 weeks old). This is very important, even in the bottle, these glues thicken appreciably with age & I'm sure bonding strength is compromised.-Spread a 'wetting' layer of glue on both surfaces & let it soak in for about a minute (but not too long - foaming BAD)- Used moderate clamping pressure to assure a tight joint, but not enough pressure to starve the joint.This procedure results in good joint & as I said, destructive testing always resulted in wood failure, not the glue. Given all this, I plan on using Gorilla glue on my Piet wherever I do not have to rely on it as a structural agent, although I suspect I could. It does great for laminations, and eliminates all the mixing & curing issues that go with T-88 or resorcinol. And, unlike the Titebond glues, it is waterproof when cured (I glued up a sandbox with it 5 years ago & despite year-round exposure to the elements, the glue had not yet failed as of last Fall - don't ask me t5o go check now, there's 6 inches of snow on the ground & more coming down).As with anything else, all the usual disclaimers apply to the above statements - I'm statisfied with how Gorilla glue works for me - your mileage may vary.Kip GardnerOn Feb 26, 2008, at 4:41 PM, Owen Davies wrote:> >> Ryan Mueller wrote:>> I understand the desire to want to be able to get what you need >> when you want it.

Hey thanks Steve. I have saved this to see what I can do with a cowling. Iplan on using the Corvair with the longer fuselage. But your suggestions aregood and I will search for a program, and then hit the list with a requestfor a cad file of the corvair engine. I bet William Wynne will have one.Regards,RobCheck out our EAA chapter website to get the news from the North.www.eaa42.org, soon I will be putting up a website with Alaska Pientenpolprojects, so keep an eye out for it this month.RS-----Original Message-----

RE: Pietenpol-List: Continental engine drawing fileFor those of us running older versions of AutoCad, a .dxf file would be much more useful than the .dwg created by the newer versions. .dxf is a quick and easy export conversion. ----- Original Message -----
