Teak is a hard wood with an open pore structure, similar to mahogany. It is seldom used for guitars because it is somewhat difficult to work, and very hard on tools.
This beautiful instrument was built from a teak cutting board that I got for free from Home Depot for review. 32" Eden neck, active electronics. Teak is hard enough for a simple oiled finish. This one was built with a minimum of tools, mostly by hand, to show that it can be done and how.
All the little bits and bobs that I used to order cheap from China have become much harder to get. eBay is a shadow of what it was just a year ago, there is not nearly as much cheap loothery supplies. But even if you find something, half the time it just disappears in shipping. Or at least it seems to disappear in shipping - a lot of tracking numbers from China are completely imaginary. As soon as you order something, they issue a tracking number to lock it in. That doesn't mean it shipped, or that it ever will! Fortunately, eBay makes it pretty easy to get your money back from such scammers.
