Some Thoughts on Wooden Wheels
The following are some thoughts that came to mind while watching the video included at the end of this post. I've made hundreds maybe thousands of wheels using the hole saw method. It works, and it can work well, but as with anything, there are pluses and minuses. I would never use vegetable oil to finish anything. Vegetable oil can and will eventually go rancid and can mold. If you want to use an oil and beeswax finish, use mineral oil. Mineral oil will not spoil. Wheels should have spacers between the wheel and the body. I use nylon washers, but metal washers will work. If you do not use spacers, the wheels will rub against the body. Not only will this remove the finish and eventually wear into the wood but the additional friction increases the rolling resistance. Sometimes to the point where the wheels slide instead of turning. Always dry fit you axle pegs with the wheels if they are too tight or too long and you don't know this before you add glue, you could ruin the toy. ...
