Bending tube
Posted: Mon Feb 10, 2025 8:39 pm
I finished up a Morton M-5 last year and had to bend 3/16 bass tube with 3/16 radi for the intake pipes with good success.
First I annealed the tubes. I was lucky because I had a fire in the fire place the night before and had a whole bucket of ashes. There were still even some burning embers left. I just put the tubing in the bucket of ashes and completely covered the tubing.
I let it sit till it was completely cool. About 2 days in my case.
When the tubing came out it was no stronger then 16Ga. copper wire.
I then filled the tubes with a product called cerrobend (you can also use cerrosafe one melts at about 125 degrees and the other at about 145 degrees.) You can get small bars on e-bay.
After that just take your time and bend away. I would suggest you bend around something just to get things uniform.
When done you can either drop the part in hot water or just hold a torch on it for a few seconds and out it comes ready to be used again. Here's a a pic of some of the bends.
