The fittings were a good idea but there is not enough room to make the bend before hitting the battery so I silver soldered the tubes into the mechanism, painted it, and that works well.since the tubing is already annealed it did not weaken it. I now have everything in place axcept the control wires and that should be here today. I have decided that using a sleeve withva setscrew is the best way to anchor the wire so will make a couple of those. Threading the tube in for the shutter control was a little tricky up at the front but there wasn't much trouble pushing it through the space beside the radiator and it will be good and solid.
