 |
|
I am having problems with the fuel line bends. I have one of the 180 degree benders and get good results in most cases, but when a "S" bend is required it is impossible to get the second bend to start without a significant amount of straight line between the tangent points of the bends. I was wondering if anyone has had this problem and if one of the spring type benders might be the trick.

I have been able to get closer "S-bends" by bending from opposite sides
toward the center, if that makes sense. Make your first bend, then turn the
tubing around and make the second bend toward the first. Might take some
trial and error, but it worked for me.

I suspect we all had the same problem. I had to re-do it several times and I am still not happy with my bends (slight flat spots) I have seen some pictures of guys with the improved Andair selector that gets away from the "s" turns needed by the older valves and requires only 90 degree bends although going from the spar forward and then back out through the skin still needs the "s' turn but if I recall there is enough room to have a short straight section prior to the next 90 degree bend. I tried a spring bender but it didn't help me as I recall.
