Wade,



I'm going to try to bend my frames today.  I traced the coordinates on a 

large piece of paper and will use that for a visual reference.  I have a 

conduit bender that I am going to try.  I put a layer of inner tube rubber 

inside the groove to keep from marking the tubing.  I think by making small 

bends every inch or so, I should be able to make a usable part.

Hi Wade,

You can bend the tubes very accurately if you fill and pack them with 

fine sand, cap them with a wooden plug

and set up a simple bend apparatus of clamps, a piece of square tube and 

small rigid steel casters. 

You work on a table, using it as the jig, trace the form you want on the 

table just in front of  the bend area and

do a little at a time.  You can also bend your top longerons this way 

and remove a little bend the same way.

The attached photos show how I did it (based on Larry  McFarland's approach). As Larry said, pack them with sand. Also buy the tubes  about 2 feet longer that the finished part to give you some leverage when making  the initial bend by hand around your form block. For the tighter part of the  curve towards the ends I use a smaller radius work block (not shown) of about 5  inch radius.

Thanks to all of you  for the ideas for  tube bending .And Larry I used your method for bending the longerons and it  worked great .
