Re: TUBE BENDING

[The Boat House]

I’ve tried filling the tubing with sand (no heat) Didn’t help.
I believe filling the tubing with solder should work but
while the majority will run out not all of it will. Trying
to blow it out may work if you reheat the tube several
times. My thinking is if you whip the hot tube most of
the solder should come out. To much trouble for me.
I was thinking of trying to melt some trimmer line to
fill a straight piece of tubing maybe 6" long. Then if
I could get it out I would spray it with some kind of
lubricant, sticking in some tubing, make the bend, and
see if I could pull it out. The biggest problem with this
is melting the trimmer line. Thinking is probably as far
as I’ll go here.

This is new to me.

quote Billy J:

To soften it again heat it up kinda red and quench in water just the opposite of steel.

I will definitely be giving this a try to see if I can get the same result.
