Made this child's train set for my two year old. It's all scrap cherry. The wheels are 1.25" in diameter while the bases are 1.5" wide.
The wheels are nailed into pre-drilled holes.
The hitches are sort of a half lap joint with the top half holding a dowel.
This is really cool. I like the idea of building him a train and adding cars as he ages or something. Maybe paint it with him at some point or something, real heirloom family-keepsake stuff potentially.
Or just let him play with it hard, it's a toy.
Thanks! He's liking it so far so I likely will add a few extra cars. It was the first thing he pulled out this morning so I was pretty chuffed.
Maybe a flat car for hauling his other toys.
