I know an individual who is seeking a source for telescoping hex tubing each piece of which is something like 30" long, made of low-carbon steel (the material isn't that important, but it doesn't need to be stainless or unusually tough or hard) in dimensions like 2" OD, far larger than anything he has been able to find commercially.
He is now considering fabricating jigs to hold flat pieces to be brazed into
30" sections. He is also willing to consider welding.Does anyone have any idea how to make this stuff? Six sided stock would have six joints to braze, and it would seem difficult to braze them all at once. Welding would be tough because the material would tend to move and because there might be "drip-through" into the interior which would make any telescoping difficult.
He wants to pay me to make him a jig, and I am leery of getting involved.
Comments?
