Fritz Klinke and NA Graphics just announced a new shipment of Vandercook crescents (CS-23) for oscillator worm gears.
Normally $41.00 each, NA is offering a special sale price of three crescents for $100.00. He has named this deal after me as I have been telling students and clients for years to have spare crescents on hand for emergencies. This is the high honor I have received. See the order page.
