Just completed an excavator that I made using the tracks that I demonstrated in the previous post along with a video. If you haven’t seen those the links are here.
It was fun scratch building this project, The first part, constructing the track and base for the excavator was developed as I went along. Just two track assemblies separated by a block of wood. Would of liked to have a track adjustment but was unable to do that. Each side was made to match each track as it is next to impossible to make each track exactly the same length. Made reasonable loose as one need to raise it up slightly for the elevated rollers.
After that I just used the materials that I had and down loaded a picture of one to somewhat follow. Mainly to determine the angle of the boom. Most excavators as far as the digging end are about the same. I will include here a few pictures of things I would like to point out. Attachment of the boom and cylinders and cab.
The ends on the cylinder rams, inserted a piece of flat wood then shape and sand it to fit.
The hinging of the bucket it to make it work properly is easy to make and looks more realistic too. It allows more movement of the bucket for digging scooping and dumping.
All that is needed is two bars and a connecting part

Assembled, ready to dig for Yukon Gold.
Building an excavator using the method of making tracks like I used here is a reasonable easy project. I have made a You Tube video of assembling this model, Starting with all the pieces laid out on the table, putting it together and explaining design considerations. Its over twenty minutes but if you watch it to the end I demonstrate a MAGIC TRICK that you might find interesting.This is the link..
Thanks for looking and comments and suggestions to make it better are appreciated.
Next project will be a lathe project from the land of the midnight sun.
