Quick question.

As the Wedgwood uses two X Carriage rails (of what ever type) and spare/alternative heads could be stored above the carriage rather than off to one side or the other.

Is it worth while considering putting the tool head between the rails rather than at one side or the other.

This should help reduce torsional stress, particularly if someone wanted to later try fitting a milling tool head ?????

Just thoughts for what they are worth.

Cheers

Looks funky... any chance of a vid of front and back when it's running or would that be a good-camera thing?

Calling it 'Flash-welding' reminded me of a technique for DIY spot welding using a disposable camera.

Relatively thick wires are connected to the capacitor in the camera. One of the wires would go to the barrel and the other would be clipped on to the thermocouple wire near the end to be welded. Once the camera's flash is charged touch/press the wire against the barrel and one spark latter it's attached, well that's the theory.

In reality it will probably take a few goes to get the right sized contact area between the wire and the barrel to get a strong weld without vaporize the end of the wire.

Finally if you can't workout why this is potentially very dangerous/lethal go find a better disclaimer ;-}>
