Go to your local public high school, and see if there's an evening adult ed woodshop. It'll get you access to top-end woodworking tools (I'm thinking you'd probably want to lathe-turn this on a faceplate), as well as access to a range of exotic or otherwise hard-to-find woods, and most importantly, access to somebody who can tell you how to do it.
When all is said and done, you'll have exactly the part you want, and a whole new skill set.
You wood be the teak-er's pet, fir sure. (Sorry, couldn't resist joining in.)
