Learn to resaw so you can make thin stock whenever you need it.

I use a lot of thin stock - 3/8, 1/4, and occasionally even 1/8. If you want to make projects requiring thin stock, you can probably purchase what you need from a hardwood lumber dealer - at a price. If you are using thin stock frequently, you will want to learn the technique of resawing.
This video is a tutorial for those who want to learn the basics of resawing so they can try it themselves.
If you want to do your own resawing, you will need a tablesaw or a bandsaw and a thickness planer.
