Marty_d Posted November 15, 2013 Share Posted November 15, 2013 Hmm, bit confused as to why someone thought that was funny. Any sheet metal fabricator will have a bending brake that'll handle 2.2m easy. Just today I visited my local sheet metal worker to do the 21 degree bend on the lower trailing edge skin.

Thanks for that, that was my first thought too, but none of the sheet metal fab places near me are open on weekends ... Not able to get time during the week.. But I'm still looking... From last time we spoke, I've scratch built the rudder, and am now starting on the horizontal stabilizer.. Regards Keith. Link to comment Share on other sites More sharing options...
Yenn Posted November 19, 2013 Share Posted November 19, 2013 Be careful with sheet metal workers, their working with steel does not require the same bend radius to prevent cracking that aluminium does. Check that they can get the radius you need. Link to comment Share on other sites More sharing options...

sain Posted November 20, 2013 Share Posted November 20, 2013 If you've got a fair bit of bending to do it might be worth rolling your own. Nice description of one over here: http://www.eaa.org/experimenter/articles/2009-05_howto_brakes.asp Link to comment Share on other sites More sharing options...
