Abstract: A grinder tool with blind mounting of a disc includes a center alignment mechanism having a first contact and a second contact and a rotational device including an axle that is movable with respect to the center alignment mechanism. A hub is mounted to the axle including a first coupling interface. The disc has a second coupling interface for mating with the first coupling interface. The center alignment mechanism is movable a mounting distance relative to the hub and contacts the disc with the first contact and the second contact to center align the first coupling interface with the second coupling interface. The rotational device is to slowly rotate the hub to angle align the first coupling interface with the second coupling interface to allow the disc to mate and attach to the hub.

Abstract: A quick set clamp device 10 includes a clamp frame 12, a slide shaft 14 having a longitudinal dimension that cooperates with the clamp frame 12 to removably secure the clamp frame device 10 to an object, a biasing member 16 adjacently disposed to the slide shaft 14, the biasing member 16 having a first end 18 that engages an outer first end portion 20 of the clamp frame 12, a binding member 22 having a first portion that slidably engages the slide shaft 14, a retaining member 26 retractably secured to the outer first end portion 20 of the clamp frame 12, the retaining member 26 engaging a second portion 28 of the binding member 22, a first engagement member 30 secured to a first end 32 of the slide shaft 14, and a second engagement member 34 secured to an inner second end portion 36 of the clamp frame 12.

Abstract: An adjustable support 12 for a stringed musical instrument such as a cello 10 includes a shaft 14 that is removably inserted into the cello 10, and a support member 16 that is adjustably disposed upon and secured to the shaft 14. The support member 16 includes an insertion portion 26 with a stabilizing bushing 72 disposed thereupon for stabilized insertion into an aperture in a bottom portion 11 of the cello 10, an annular portion 28 with an annular wall 34 for engaging and supporting the bottom portion 11 of the cello 10, and a lower portion 30 for securing the support member 16 circumferentially about a cylindrical outer wall 18 of the shaft thereby allowing an artist playing the cello to select a comfortable elevated and stabilized position of the cello 10 above a floor surface.
