 |

OK, I am officially going crazy!!! I am trying to bend the lower longerons for the rear fuse on my XL. I have tried a variety of things and ruined a nice piece of extrusion. I am trying what Scott Laughlin uses on his website and it bends the metal nice and easy, but I dont have a uniform shape to the fuse I can get it to bend in the right spot, but it does not stay round. There are flat spots in it. Can anyone tell me if there is a way to get the smooth countor of the fuse. I am using .75x.75x.125 wall extrusion due to availability reasons. This is stronger than what is called for in the plans and may be the reason why I am having so much problems. Can you KIT BUILDERS tell me if yours came already formed in the kit? I don't think they do, but have not called and asked. Any help would be appreciated.

Yes, the kit comes with the longerons already bent. Of course they don't match the pre-drilled holes in the bottom skin so there are still problems to resolve.

Larry:
Thanks for the reference to my site but I got the idea
from Larry McFarland's pictures (macsmachine.com).
You might want to look at how he did it. If you go
slow, with a little persistence you can get it just
about perfect. Go slow and if you over-bend it, just
nudge it back into place. The top flange tends to
kick up so you might need to use a hammer and a vise
to bring it back to 90 degrees with the other flange
after it is bent. You will see this when you try to
lay it flat on the table after bending.
Take your time and you will get it. You will run into
a similar situation when bending your fuselage and
canopy hoops (actually it's worse since you can get
dents in the tube) and again with the canopy frame
when you bend it to match the angles you are working
on now!
For the hoops I found that a pipe bender works even
better than the clamps-and-pipe method. I got a cheap
one on-sale from Harbor Freight. It's a 12-ton unit
(talk about overkill) but it has a 1/2" shoe that fits
the 3/4" aluminum pipe well. Here are a few pictures:

Here's a new one I just posted for clarity:
http://www.cooknwithgas.com/6_13_06_Canopy_Hoop_Bending2.JPG
This won't ease your pain right now but it will make
things a lot easier when you are building your
fuselage hoops real soon.
Press on Larry - you will succeed.

Larry-- I used the same size material.----- scratch built---- bending forms MUST have more of a curve than what plans for template shows to allow for spring back.
I had one template for bending and one for finished product. My longerons, all 4 came out really, really nice( I don't like to use the word "perfect" in scratch building) I'll match them to the factory's anyday----- contact me off list, if you want more info.

Hi Larry,
My 601XL kit came with pre-bent longerons. They are currently lying under my work table so I see them all the time. There may be some other pieces to bend (haven't gotten that far yet) but there are a couple of extruded angles that were supplied to me already bent.
