tubing bender

[Randy Cuberly]

Hey!

Does anyone make a good 1/8 inch OD tubing bender.  I seem to have lost all of mine (or lent them to someone who forgot where they came from).  Truthfully I don't really miss them because the ones I had didn't work very well anyway.

I've found a great number of really good ones that start at 1/4 inch tubing and as you all know they do not make them for our typical applications (stunt).

Thanks,
Randy Cuberly

These little things work pretty well, I think Harry Higley made them originally.
(I have one somewhere   )

  Randy,
  I have  had some fair fortune with the  Du Bro  785 and there is a more professional type on Amazon I think I have one in my basement.  Amazon has several.  Also a few years ago I discovered the use of Refridgeration copper tubing it's very pliable comes in a coil 12" diameter maybe $.50 per  foot.

The yellow one is Graupnerīs and
the black,brass wheel ,chrome handlebars works perfect to me which was a "buy now" bay found.
Next time I will test K&S bending 1/8 inch / 3mm OD copper tubes.

Du-Bro makes 2 sizes of tube benders. I use em' to make tank plumbing.....works great.
Copper tubing inside the tank and annealed brass (K&S blue pkg) for Uniflow manifold (side of fuse).

Hi Randy;

If you are bending brass or copper tubing that you obtain from one of the hobby suppliers like K&S Metal you can eliminate a tube bender by "annealing" the tube. You can do this simply by gripping the tube with a pair of pliers and heating the tube using a Berns-O-Matic torch. Just get the tube red hot and then allow it to cool down. This will anneal the metal and allow you to bend it by hand or with pliers easily with out any crimps occurring. When I was building the GRW fuel tanks I purchased only annealed copper tubing since there were a large number of complex bends that needed to be put into the tubing.

Hope this idea helps
