HOn30 electric Boxcabs for the Quarry Line

Bernd exceptional work!!

Learning CAD then the machines would take a lot of time.  Glad you mastered them and put that knowledge to good use.

On to more brass bashing.

Here the machine is cutting out the boxcab ends. I show four being cutout but will need eight total for front and back.



The first four cutout and ready to be released from waste brass.



Next a pocket .020" deep was cut into a piece of 6160.



The part was clamped down, the head swung to 45° to mill a 45° angle on the edge of the sides and ends for a better fit when soldering them together.





Not all works out well all the time. Occasionally the machine get hungry and eats a piece. No problem, another gets cut out. That's what's so great about CNC machining. A quick set up and call up the part program and cut away.



Once all the parts have been prepared it's time for some assembly. I'm using my DYI resistance soldering rig to solder the sides together while being held in a 90° soldering fixture.



The end result.





That's it for now. Next I'll show how I made the louvers to fill the upper square openings.

Thanks Jerry, appreciate the kind words.

Anybody can learn CAD. Much easier when younger, but it's learnable. I started out with a friends pirated AutoCad 10 on a DYI parts assembled Intel 80286 chip DOS computer many years ago. It's no different than learning to assemble a kit and weather it. It takes practice, then more practice and then a little bit more practice.

My main purpose of showing this is that some younger person interested in model railroading will try this instead of asking where can I find a file to 3D print this engine. The Star Trek replicator has not been invented yet and probably never will.

Thank you very much Tom.
