A cylinder vice includes a vice jaw, a chain retainer, and a hydraulic assembly. The vice jaw is positioned between side braces and include outer and inner plates. The outer plates include a top edge having a V-shape geometry. The outer plates include a female slide configured to interface with a male slide of the side braces. The inner plates include a top edge having another V-shape geometry. The inner plates include a bottom edge that is configured to interface with a piston. The chain retainer configured to retain a chain end positioned in a slot configuration of the chain retainer and fastened via retainer handles. The chain retainer includes a handle on each side of the slot configuration such that each handle is positioned in the notches of the side braces. The hydraulic assembly is configured to actuate the piston against the bottom edge of the inner plates.

An apparatus for applying pressure to an edge surface comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to the frame and are rotatable relative to the frame. At least one of the first roller or the second roller is translatable relative to the frame. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is coupled to the frame and is configured to operate in tension. The second biasing member is positioned, in compression, between the frame and the rotation-control member.
