This project came from the wood magazine. It is a companion to the wood crane that came out last year. I built that earlier so I was excited to see the excavator in the previous issue of Wood Magazine. The parts were actually stuff that I could buy from the hardware store except for the wheels and pegs. and it was easy to make. The only issue I had with the crane and excavator was that it was made out of 6/4 and 2/4 material which is a lot of planing and glue ups.
Both are made out of birch and walnut. The expensive part of these projects was the hardware but well worth it.
This project is where I learned how to make tight movable joints. My son had fun with it once it was completed
