Back when I decided that I needed to get some experience working with basswood I decided to build this in 1/25 scale.
Everything you see is basswood, except the tire which came from my parts box, and the climbing pegs are Evergreen rod. The slide surface is BMF.
The original was in a 1970s Popular Mechanix Magazine.
The entire set of plans was there with dimensions. I just built it in 1/25 scale instead of 1/1. I got the experience and confidence to work in wood. I've done a few things since, but this was the initial project.
