ABSTRACT:
A biscuit joiner 11 has a pair of selectively usable retractable antiskid pin subassemblies 13, 15 for increasing the frictional resistance of the shoe assembly 23 with a workpiece when making a cut in the workpiece. Pins 19, 21 are biased forwardly to an extended position by a spring 45. To permit selective use of the pins 19, 21, a retractor 47 retains pins 19, 21 in a retracted position. Retractor 47 preferably comprises a cam 59 and a cam follower 61 and is actuated and deactuated by rotation of pins 19, 21 within chambers 43. Each pin tip 55 has a plurality of peripheral points 73-76 which are particularly effective for reducing skidding on a workpiece.
