I’m sorry, I was a bit busy, so I didn’t forget the project, just have no time to write… After the arm system welding I started to plan the chain elements. The planetary drive sprocket-wheel more or less finished… here…
First trial with the self designed and laser cut metal plates. At the weekend I worked on the boom and stick of the excavator. I got the laser cut parts on Wednesday. Two components were bad, that was my bad,…
The last two weeks was a little bit busy, so I couldn’t work on the RC project, but now… I redrew the sheet metal components of the arm. It was just a fine tuning. Yesterday I finished the bushings’ plan…

Now I try to explain how I think the arm component construction. All arm parts or items will be made from metal plates. This is an easy way to create strong and not too heavy items. The metal plate is an…
