TT GP38-2 Powered Chassis Build

All I need to do is cut the .030" thick brass to proper length.

First cut being made.

Almost done.

And the end result. The one on the left is the hand made one. The machine cut one in the middle and the other
fitted inside the shell. The shell still needs a little tweaking
to make the chassis fit.

The chassis has been opened with a longer opening for the neoprene tubing. There still is not enough room.

Since the tubing wasn't perfectly round, when running it caused a vibration in the chassis. This was not expectable.
It was decided a U-joint would be a better choice.
A miniature prototype U-joint was thusly machined.

All the parts to make one U-joint. That's an 0-80 threaded nut to the right.

An assembled U-joint.

Used a resistance soldering rig to solder the small pins.

Changed the design to use a steel center instead of a brass tube.
