These plugs are great for painting the finished product. However, it is not so good when using different types of wood, such as cherry or some rare woods. I made a mount to make my own corks from scrap wood I used for the project. However, I just saw a video of the Kreg connector that can be used with the Kreg J3, J4 and J5. Allows the user to make corks from any wood they want.
