Abstract
A relatively rigid device for holding a circular cylindrical tapered shaft including a top and bottom end, a first and second outer side opposite each other, a third side opposite a fourth side, the first outer side having a channel extending along its length which abuts a tapered first bore, the second outer side having a channel extending along its length which abuts a tapered second bore, the tapered bores extending from the top end to the bottom end between the third and fourth sides, each of the third and fourth sides having an outer grip surface upon which force can be applied to firmly grip the device. Also, a method of holding a cylindrical tapered shaft including the steps of (a) providing a relatively rigid device with: a channel extending along a first outer side, the channel abutting a tapered bore, a solid volume portion in proximity to the tapered bore, both of which extend from the top end to the bottom end of the device between a third and fourth side, each of the third and fourth sides having an outer grip surface; (b) aligning an axis of the shaft to be generally parallel with an axis of the tapered bore; (c) moving the shaft through the channel into the tapered b…
