The Master Airscrew Balsa Stripper has been engineered to accurately cut balsa sheets of up to 1/4in thick into strips up to 1/2in wide. The design has a lead screw with 32 threads per inch so that each turn of the wheel will move the blade 1/32 of an inch. Starting with the blade against the stop, four turns will produce a perfect 1/8in strip. Never again will you be short of strip wood for your building project and, what’s more, if you cut your own you’ll save money.
