Ingenious Balsa Stripper
HOW often have you needed an odd-sized or tapered balsa strip? Here is an inexpensive, easy to make, and very accurate beam balsa stripper. Since it handles sheets only up to 3/32 in. thick, it is designed with small models in mind, such as flying scale (especially Peanut), P-30, Embryo, Pennyplane, etc. Although I have used it to build very light indoor ships, you might consider a very sophisticated and accurate micrometer beam stripper if you want to build stuff like indoor microfilm. (Micrometer strippers are available for $41.00 from Ray Harlan, 15 Happy Hollow Rd., Wayland, MA 01778.) For anything less exotic, however, this stripper is ideal.
