Hi Kevin,

thanks for your comment!

About TIG welding, this is certainly not my job or occupation and not every bead is nice, so I had to learn and practice. For me it was very helpful watch Jodie from weldingtipsandtricks. Most of his videos is about TIG welding, but he shows MIG and Stick, also. The 1st I learned was to change the Tungsten into a new grinded, sharp one once if it got stuck.
Most parts here I welded without filler rod, just heated up and melted the corners together.

Here some more pictures from the under carriage.

...and some more. If there are any question feel free to ask!

Well, it is the best if you practice again and again. Today I welded a couple hours using grey tungsten and after a while I tested the gold ones. But those didn't work as well as the grey ones, I got stuck very often with the same settings on the welder. Because of this I switched back to the gray tungsten. Pictures from this welding will be posted later.
First some pictures from the 2-stage Planetary gear inside the drive wheel. Gear ratio is 20.36 : 1.

Some more from the drive train. The gearbox is shimed with thin brass sheets for proper chain setup. The motors are brushless outrunner with 120 Watt and 760kv.
