Boy John, Tough one. I have see some guys bend some angle, using the hardwood form and some pipe clamps.(do a Google search for pipe clamps). You clamp the starting point of the bend, and then slowly work your way along the radius bend until you have your 14". That would be a trial-and-error thing for me.

Does anyone know what kind of shop would have a tool that would put a nice smooth 4-foot radius bend 14" long into a piece of extruded angle 6061-T6, 1.25" x 0.75" x 0.125t, with the bend stretching the outer edge of the 0.75 flange? This is aluminum angle with the radiused inner corner. I can probably do it with a grooved hardwood form and a rubber mallet, but I'd gladly pay somebody to do it for me that could assure perfect results the first time.

I just ordered some shorter pieces to practice on in case I couldn't find someone who is equipped to do it right the first time, but I'd rather not do trial and error.

From: "Ron Lendon" It really doesn't need to be trial and error. If you control to process and keep the bending between the tangent lines, you just sneak up on it. The extruded angles will need to be bent and flattened as you go along. Here is a link of a setup I used to bend the upper longerons on my XL. http://mykitlog.com/users/display_log.php?user=rlendon&project=113&category=4167&log=81730&row=54 If you are anywhere near me I can probably do this for you in a couple of hours. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Corvair Engine Prints: http://home.comcast.net/~rlendon/site/ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=278975#278975 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith701801-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith701801-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/zenith701801-list Browse Digests http://www.matronics.com/digest/zenith701801-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.
