Cristals original question asked about both AN hardware for motor mounts AND prop mounting hardware. I aksed for a chart suitable for AN hardware as Aircraft Spruce lists it AND gave an example of what one particular prop manufacturer specs. She's already been told more than once in posts previous to mine that the prop manufacturer specs the proper torque value for thier prop. I guess i should have left the Warp example out of my post so as not to confuse you.

Prop bolt torques are based on the required force to properly clamp the prop without crushing it, which will be different depending on the prop construction. Use the manufacturer's recommended torque values and nothing else. For wood props, here's a good writeup from Sensenich: http://www.sensenichprop.com/sen_html/aircraft_cet/install/cf-a.pdf -Dana -- quote] Read this topic online here: http://forums.matronics.com/viewtopic.php?p=215892#215892 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-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/kolb-list Browse Digests http://www.matronics.com/digest/kolb-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.
