Any secrets to bending the longeron easily?     

   

I seem to be banging on it without any results.  I’m assuming that I must either start hitting with more force or get a heavier mallet.

I recall putting it on a vise and hitting it with a  mallet, bend rather easily for me. I started close to the bending point and once  I had the slight bend hit it hard a couple of times a little farther out. Pretty  much followed the plans, as I recall.

 If you have it positioned solidly in a vise hit it  hard to get the initial bend going, should be easy after that.

The answer was obviously, just use a heavier mallet.  I ran out a bought a much larger rubber mallet and bending became a non-issue.

Pascal has it right.  You might take a look at my  pictures here:  http://www.soundingsresearch.com/RV-10/Empennage/Tailcone/Tailcone06.htm

  

 Use a shot filled mallet.  Don't be shy.  Just  stress it in the right direction and whack it just in front of the vice jaws  where you have it secured using the plastic or aluminum jaw  inserts.  Take your time and don't be nervous about it.  It will  bend.

Be sure to preload it.  I was timid about bending it at first and the mallet blows would slightly deflect the longeron but it would snap right back.  If you preload it well first(bend it in the desired direction of bend with your free hand until it begins to strongly resist you), it bends very easily with each tap.  So much so that I could see the bend occur with each blow.  Once I figured out the preload amount, it was pretty easy to get the bend and correct any over bend and 90 degree deflection in the angle.  

   

Just make sure that you have the bend mark aligned precisely where it is secured in the vise and it should go smoothly. If you go a little over, you can bend it back without issue (but try to minimize the mount of bends so you don’t overstress the material.)  Just follow the same procedure.  

   

At first I was not looking forward to this step, but after doing it, it was one of the easier and less problem prone tasks.

An interesting thing I noticed when I did this was that when I laid the longeron on the fuse skin to check the bend, I noticed the long straight part had a slight bow in it, so I carefully took that out too. Laying it on a flat table or bench with the fuse skin also lets you check it for twisting that might have occurred when beating the bend in it.  I also got to take out a little bit of twist on one of mine.

That's exactly how I remember it going, just when you get it to fit in 

one axis, you check and the other is out, it took a series of back and 

forth 'sessions' to get them to fit in both axis.

Thanks for the info.....



I'll have to check the other axis.  I did check the bend on a flat table,

but wasn't specifically looking at the other axis.  I would hope that if it

was off, I would have noticed it.  But I will check again just to be sure.

Pascal:  

  

 I originally had to go into hibernation on the build  because my work sucked up all my time and energy.  However, just recently  another impediment came along.  I hate to rent.  All that good money  going out the window, so, guess what?  After whining about not having a  plane to fly until some at the airpark ran the other way when I turned the  corner, I finally bought myself a plane.  I'm now am having so much fun  flying that that and the job give me no time to build.  I do love  building though, so do plan on getting back to it.  Maybe sometime  this winter.  Unless, of course, I decide to redo the panel on my new  toy.
