New 3 Wheeler Model
Materials
The woods I used for the model were Black Walnut for the wheels, chassis, and body, and Hop Hornbeam for the cowl and engine. I wanted a natural wood finish, the white Hop Hornbeam used for the 'chrome' bits would contrast nicely with the dark Black Walnut. Any other white, closed grain hardwood would do, I just happen to have some Hop Hornbeam from a log I spotted in a load of firewood several years ago.
Measurements are actual size not nominal sizes.
