The primary tool of our trade -- although expensive (about $US 320 for a nice 20 inch (ca. 50 cm) borer), you simply can not conduct tree-ring research without one. If this is too expensive for your class or school, contact your local forestry department, especially if a university or college is nearby. The US Forest Service usually has lots of these, as do state forestry offices. Even Cooperative Extension services of local universities have these. Usually they will let your class borrow one, or provide a demonstration.
If you do invest in one, learn the proper use and care of this instrument! They are precision instruments and should be cared for their entire lives - plenty of lubrication, cleaning, and sharpening. If you care for it properly, it will serve you well year after year in the field. Learn from an expert if one is nearby - it will save you much time, trouble, and expense in the long run!
