It's just rounded it same as my Chief. Sanding that small amount off the rib ends won't compromise any strength. In those days of yore it was just assumed that the builder would just do that. Also.I've just had a look at my rib jig and the spar opening is 4 3/4" at the rear face ( 1 in thick spar). Again, a long time since making those ribs. I may have just fudged the profile a wee bit to accomodate the whole spar. http://www.clifdawson.ca/ The upload function for my web builder quit and I gave up on any help from the program folks so the last pics where some five years ago. Here's a couple of pics in the here and now.

The complete Pietenpol-List FAQ including the Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/Pietenpol-List.FAQ.html Thank you, Matt Dralle Matronics Email List Administrator [ Note: This FAQ was designed to be displayed with a fixed width font such as Courier. Proportional fonts will cause display formatting errors. ] This FAQ can also be viewed in HTML online at the following address: http://www.matronics.com/FAQ/Pietenpol-List.htm ************************************************************ ******* LIST POLICIES AND FREQUENTLY ASKED QUESTIONS ******* ************************************************************ PLEASE READ. This document contains Pietenpol-List policies and information for new and old subscribers. Understanding the Pietenpol-List policies will minimize problems for the Administrator, and will help keep the Pietenpol-List running smoothly for all of us. ****************************************** *** Quick Start Guide to List Features *** ****************************************** There are many features available on the Matronics Email Lists and each one is described in detailed below. However, using the List Navigator you can quickly access the complete set of features available for this List. The List Navigator can be found at the following URL: http://www.matronics.com/Navigator?Pietenpol-List **************************************** *** How to Subscribe and Unsubscribe *** **************************************** Simply go to the Web Page shown below and enter your email address and select the List(s) that you wish to subscribe or unsubscribed from. You may also use the handy "Find" function to determine the exact syntax of your email address as it is subscribed to the List. Please see the complete instructions at the top of the Web Page for more information. The Subscribe/Unsubscribe web page is: http://www.matronics.com/subscribe Note that you will receive TWO conformation emails regarding your subsciption process. The first verifies that your subscription/unsubsciption request was received, and the second confirms that the process has been completed. You should receive the first email within a few minutes of your request. The second conformation will arrive in less than 24 hours. You cannot post until you receive the second conformation email message. ***************************** *** How to Post a Message *** ***************************** Send an email message to: pietenpol-list@matronics.com Your message will be redistributed to everyone currently subscribed to the List. ***************************************************** *** SPAM Fighter - You Must be Subscribed to Post *** ***************************************************** When a new post is received by the system, the From: line of the message is checked and compared against the current subscription list. If the email address is found, the message is passed on to the List Processor. If the email address isn't found in the current list of subscribers, it is dumped. This serves to very effectively thwart 99% of the SPAM that gets posted to the Lists. Remember, however, that the syntax of your email address is very important with regard to the configuration of your email application such as Outlook or Eudora. For example, the following two email addresses may be functionally equivalent, but only one would pass the Matronics Email SPAM test depending on which was syntax was subscribed to the given List: smith@machine.domain.com smith@domain.com Either email address syntax is alright, just be sure that you configure your email application to match *exactly* the address you've subscibed to the List. ************************************** *** Enclosure Support on the Lists *** ************************************** Limited posting of enclosures such as pictures, documents, and spreadsheets is supported on the Lists. There are a number of restrictions, and these are detailed below. Please abide by the rules put forth regarding the content of enclosures. These are some of the features and limits of enclosures on the Matronics Lists: 1) Enclosures will only be posted to the Real Time version of the Lists. 2) Enclosures will NOT be included in the Daily Digest version of the Lists. 3) Enclosures WILL BE forwarded on to the BBS Forum Web site. 4) Enclosures will NOT be appended to the Archives. 5) Enclosures will NOT be available in the List Browse feature. 6) Only the following file types and extensions will be allowed: bmp doc dwg dxf gif jpg pdf png txt xls All other enclosures types will be rejected and email returned to sender. The enclosure types listed above are relatively safe from a virus standpoint and don't pose a particularly large security risk. 7) !! All incoming enclosures will be scanned for viruses prior to posting to the List. This is done in real time and will not slow down the process of posting the message !! Here are some rules for posting enclosures. Failure to abide by these rules could result in the removal of a subscriber's email address from the Lists. 1) Pay attention to what you are posting!! Make sure that the files you are enclosing aren't HUGE (greater that 1MB). Remember that there are still people checking they're email via dial up modem. If you post 30MB worth of pictures, you are placing an unnecessary burden on these folks and the rest of us, for that matter. 2) SCALE YOUR PICTURES DOWN!!! I don't want to see huge 3000 x 2000 pictures getting posted that are 3 or 4MB each. This is just unacceptable. Use a program such as Photoshop to scale the picture down to something on the order of 800 x 600 and try to keep the file size to less-than 200KB, preferably much less. Microsoft has a really awesome utility available for free that allows you to Right-Click on a picture in Explorer and automatically scale it down and resave it. This is a great utility - get it, use it! http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx Look for the link "Image Resizer" 3) !! This would seem to go without saying, but I'll say it anyway. Do not post anything that would be considered offensive by your grandmother. And you know what I'm saying; I don't want to see anything even questionable. !! 4) REMEMBER THIS: If you post a 1MB enclosure to a List with 1000 members subscribed, your 1MB enclosure must be resent 1000 times amounting to 1MB X 1000 = 1 Gigabyte of network traffic!! BE CAREFUL and BE COURTEOUS! Also see the section below on the Matronics Photo and File Share where you can have your files and photos posted on the Matronics web server for long time viewing and availability. ******************* *** Digest Mode *** ******************* Each day, starting at 12 midnight PST US, a new 'digest' will be started. This digest will contain the same information that is currently appended to the archive file. It has all of the headers except for the "From:" and "Subject:" lines removed, and includes a message separator consisting of a line of underscores. Each day at 23:55 PST US, the day's messages as described above will be combined and sent as a single message to everyone on the digest email list. To subscribe to the digest list, use the same subscription web form described above, and just select the Digest version of the List. http://www.matronics.com/subscribe Note that you *can* be subscribed to both the realtime and digest versions of the List at the same time.

In such a case, simply put the following phrase anywhere in the message: do not archive Your message will not be appended to the archive, but will be sent to List email distribution as normal. ********************************************** ***** READ THIS - Automatic Unsubscribes ***** ********************************************** Note that if your email address begins to cause problems such as bounced email, mailbox is filled, or any other errors, your address will be promptly removed from the List. If you discover that you are no longer receiving messages from the Pietenpol-List, go to the following Web page, and look for your email address and a possible reason for your removal. The Matronics Email List uses utility called the "Email Weasel" that automatically looks though the day's bounced email for addresses that caused problems due to common things like "user is unknown", "mailbox full", etc. If the Email Weasel removes your email address from the Lists you will find record of it at the following URL: http://www.matronics.com/unsubscribed If the problem listed on the web site above has been resolved, please feel free to resubscribe to the Lists of your choice. ******************************* *** List Member Information *** ******************************* If you have not done so already, please email me your phone numbers and paper mail address in the following format: smith@somehost.com Joe Smith 123 Airport Lane Tower, CA 91234-1234 098-765-1234 w 123-456-7890 h Please forward this information to the following email address: requests@matronics.com I have a file of such things, that I typically use to contact you when there are problems with your email address.

Unlike an ordinary web page where the content needs to be submitted to Matronics for inclusion, the Wiki permits the users to construct their own pages and have them visible immediately. While constructing pages for the Wiki is not difficult, some may not be comfortable building pages. In that case, simply prepare the text and any images and email it to: wiki-support@matronics.com One of the volunteers on that list will take your submission and construct a Wiki page for you. Often someone produces a particularly useful posting in email one one of the Lists that would be of general interest.

Every year during November I run a low-key, low-pressure "Fund Raiser" where, throughout the month, I ask List members to make a Contribution in any amount with which they are comfortable. I will often offer free gifts with certain contribution levels during the Fund Raiser to increase the participation. The gifts are usually donated by companies that are themselves List members. Your Contributions go directly to supporting the operation of the Lists including the high-speed, business-class Internet connection, server system hardware and software upgrades, and to partially offset the many many hours I spend running, maintaining, upgrading, and developing the variety of services found here. Generally Contributions range from $20 to $100 and are completely voluntary and non-compulsory. I ask only that if person enjoys the Lists and obtains value from them, that they make a Contribution of equal magnitude. Contributions are accepted throughout the year, and if you've just subscribed, feel free to make a Contribution when you've settled in. The website for making SSL Secure Contributions is listed below. There are a variety of payment methods including Visa and MasterCard, PayPal, and sending a personal check. If you enjoy and value the List, won't you make a Contribution today to support its continued operation? http://www.matronics.com/contributions Thank you!

You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the Pietenpol-List in the manner described below may result in the removal of the subscribers from the List. Pietenpol-List Policy Statement The purpose of the Pietenpol-List is to provide a forum of discussion for things related to this particular discussion group. The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. - Occasional posts by vendors or individuals who are regularly subscribed to a given List are considered acceptable. Posts by List members promoting their respective products or items for sale should be of a friendly, informal nature, and should not resemble a typical SPAM message. The List isn't about commercialism, but is about sharing information and knowledge. This applies to everyone, including those who provide products to the entire community. Informal presentation and moderation should be the operatives with respect to advertising on the Lists. ------- [This is an automated posting.] do not archive ________________________________ Message 10 ____________________________________ Time: 11:24:09 PM PST US From: Matt Dralle Subject: Pietenpol-List: Official Pietenpol-List Usage Guidelines Dear Listers, Please read over the Pietenpol-List Usage Guidelines below.

Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. - Occasional posts by vendors or individuals who are regularly subscribed to a given List are considered acceptable. Posts by List members promoting their respective products or items for sale should be of a friendly, informal nature, and should not resemble a typical SPAM message. The List isn't about commercialism, but is about sharing information and knowledge. This applies to everyone, including those who provide products to the entire community. Informal presentation and moderation should be the operatives with respect to advertising on the Lists. ------- [This is an automated posting.] do not archive ________________________________ Message 11 ____________________________________ Time: 11:34:19 PM PST US From: "Clif Dawson" Subject: Re: Pietenpol-List: Re: Rib to Spar fit No, I plotted it. You can't trust paper that size. With various levels of humidity the length changes significantly. There is, or was then, an anomaly. One of the top plot numbers is off. Everybody just smoothed it out. After all this is a KS airfoil. :-) (kitchen sink) Is your spar the 1" width or the 3/4"? ----- Original Message ----- From: "PoconoJohn2" Sent: Wednesday, April 01, 2020 7:56 AM Subject: Pietenpol-List: Re: Rib to Spar fit > > > Are you using the printed paper?
