How to Make Wooden Chocks

Start with solid piece of 4×4 inch treated wood, around 12 inches in length.

You can usually source this easily enough from building sites or scrap yards without having to visit the store.

The idea is to mark a 45-degree wedge angle to work on a standard 15-inch tire.

If you want to be exact, you can mark the angle of your individual tires on a piece of cardboard and transfer this recorded angle onto the wood.

Using a handsaw or electric saw, cut along the angle line that you’ve drawn, and then you should have a nice wedge-shaped chock.

Additionally, you can attach a rope by screwing a small metal loop into the back of the chock for easy extraction.

Or simply attach piece of rope by stapling each end to each side of the chock, the loop facing backwards.

Using a staple gun can be an effective method of attachment.

There you have it, a home-made wooden chock, fit for purpose and ready for use.

It’s always advisable to seek the most level surface possible before you decide to deploy your wooden chocks.
