Broke the throttle on the six, need CSOB ideas Options

[djm914-6]

It's been a long time comming I suppose. The lever that the pedal pushes on has been tilting to the inboard until the throttle rod rests againts the floor board. Sometimes I'd attempt to bend it back, but most of the time I'd just del with the squeeking.

Well, there's no more squeek because the throttle lever of the pedal assemble broke off. I got the car home by bending he manual throttle lever just enough to catch the throttle cable end. I drove it by pulling back on the lever.

Now, I need some ideas. I know that the six lever isn't so common. What's the changes of having this one welded up and reattached to the pin that goes into the pedal assembly?

Brazing is crap at butt joints however. It's much better when there is an overlap.

I disagree with that. When I said scads of racing chassis, I meant spaceframes. All built using lots of small round tubes fishmouthed and butt welded together, sometimes joining a good number of them into one joint. The lower temps obviously helped in reducing warpage problems when joining a lot of tubes together. And when I said scads, I meant SCADS. Most of the F1 frames built from 1950 to 1965 were brazed spaceframes. They went to monocoque construction after that, but minor formulae, like Formula Ford, continued to use brazed spaceframes until relatively recently. A good number of aircraft frames were also made this way. The fillet of bronze at the joint naturally had a nice radius, which meant it wasn't a stress riser, which a normal weld bead will be.

Brazing can also join two dissimilar metals together, which you cannot do with fusion welding.

I have a very nice book on motorcycle chassis design, written by an engineer that designed a number of racing bikes that did quite respectably in the 70s and 80s, which advocates brazing as generally superior to any other method for making spaceframes. TIG is probably better, really, but brazing shouldn't be discounted.
