It has some twist in it that would be a big job to t ake out if not impossible. In the past I have jacked the table then shimmed 2 x2 Aluminum tubing laid perpendicular the long axis of the table to have lev el supports on which to build. The latter is a cumbersome procedure and is e xaggerated by a sloping garage floor. I did weld up some screw jack levelers for the table that hold it steady and get it near level but I still need to address the twist. I have flipped the R wing, right side up and want to dri ll and cleco the nose skin and leading edge of the upper rear skin to the sp ar but I want to ensure the 2x2=99s are level in the X and Y before st arting. > > I fear a 4 foot level is not accurate enough as I would have to either att ach it to a longer =9Cstraight beam=9D or level in increments al ong the length of the table. I have thought about buying or renting one of t hose self leveling lasers, using an optical level and even a piece of clear t ube filled with water or some other fluid. I may be over thinking this for a CH-701, so I wanted to see what others have done to ensure they are buildi ng on a level surface. > > Regards, > > Perry Delano > > > ========================== ========= ========================== ========= ========================== ========= ========================== ========= > ------------------------------------------------------------------------------------- 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.
