Cooling Lines
Time to make some aluminum cooling lines. 1.25" OD X 0.058" 6061-T6 Bare Drawn Aluminum Tube does not like to bend!
It must be annealed first and even then it can be hit and miss (as you will see...).
Rubbed with bar soap and heated with a torch until the soap uniformly darkens:
I liberal amount of lithium grease applied to the bender dies and:
One end done, time to do the other end...
and ...doh! Couldn't have happened on the first bend could it
Two more sticks are on the way for remaking that one.
You may have noticed the bead rolled into the end. I made this little tool for doing those:
I'm going to add some surface area to the "saddle" to reduce the indentation on the OD.
That other line shown is for the upper coolant line. Here's what I'm going for (lower line still needs to be remade)
Clamps will all be either T-Bar or Shrink-Clamps
