Size Tubing Please?

Toesup, I'm building two Springers side by side, which will be my second boat build. The first was a Victor V-12 kit. My question is, what size tubing did you use and did you pack your tubing with salt, before making your bends? A visitor at our pond yesterday said, he packed his tubing with bakers salt, which is finer then ordinary table salt. He couldn't remember the size of his tubing. Thanks for your anticipated help.

The tube in the pic is about 5/32" copper..

I generally use 1/8" bore Ali tube. Crimp one end and pack tightly with salt.. and crimp the other end shut, not allowing the salt any space to move.
When you start to bend, try to do it in one 'fluid' movement and not stop during the process..
Cut off the ends and clean up the tube.. and roll the tube back and forth until the salt is all clear from the inside of the tube.

Don't know if you're aware of this, but K-S Products does sell soft aluminum and brass tubing, which doesn't require packing, and bends comfortably around a motor for a cooling coil.

Sometimes hard to find, though---.

I bought a coil of annealed aluminum tube from Mcmaster-Carr. They have it in various diameters. It bends easily without kinking. I have made numerous cooling coils from it, and you can easily get the coil to be quite snug with tight wraps.

Toesup, very impressive work. I really look forward to watching the development of this project.

Thought you might find these pics interesting. The tug " Independence " was just launched at the Derector shipyard in Bridgeport Ct. Built for Boston Towing and transpotation as an offshore support vessel. Length is 128 ft with a 44 ft beam. Equiped with Rolls Royce Z drives. Propulsion is two 16v4000 MTU with a total of 5,400 hp. The underbody looks massive out of the water. More pics of construction on the Derector website.

Toesup Boat Werks update.

The wash ports and cut outs for the forward bollards have been made... and some filler to the insides of the hull where the deck is to be supported..
I've installed the drive mounts, the motor blocks and the motors.
I'm in the process of making up some support bulkheads for the staples, superstructure and the winch. The forward staple has yet to be finished and added to the bulkhead..
I've also developed a battery box... i dont want the battery rolling around in the hull when trying some pulling maneuvers!..

I know!...

I have to get all that woodwork in for support / strength round the staples / winch (I hate that tearing wood sound) and still be able to gain access to the motors and the tops of the drives...

Erm... "It was designed like that"...
