a saw power head assembly defining a cutting axis; a work support surface member supported by the base and including a work piece support surface defining a horizontal work piece support plane; and a plurality of wheels, each of the plurality of wheels supporting the work support surface member above the base and engaged with at least one of the base and the work support surface member such that the work support surface member is movable along the cutting axis, wherein each of the plurality of wheels is axially movable along the cutting axis with respect to both the base and the work support surface member. ### Claim 2 (depends on 1) The saw system of claim 1, wherein each of the plurality of wheels is engageable with both the base and the work support surface member. ### Claim 3 (depends on 2) The saw system of claim 2, wherein: each of the plurality of wheels defines an axis of rotation that extends in a horizontal plane; and at least one of the axes of rotation is located in a horizontal plane that is vertically higher than the horizontal plane of another of the axes of rotation. ### Claim 4 (depends on 3) The saw system of claim 3, wherein at least one of the plurality of wheels is engageable with a first rack attached to the base and with a second rack attached to the work support surface member. ### Claim 5 (depends on 1) The saw system of claim 1, further comprising a carriage body, wherein the plurality of wheels comprises: a first wheel rotatably supported by the carriage body; a second wheel rotatably supported by the carriage body; and a third wheel rotatably supported by the carriage body. ### Claim 6 (depends on 5) The saw system of claim 5, wherein each of the first wheel, the second wheel, and the third wheel is engageable with both the base and the work support surface member. ### Claim 7 (depends on 5) The saw system of claim 5, wherein: the first wheel is engageable with the base but is not engageable with the work support surface member; the second wheel is engageable with the work support surface member but is not engageable with the base; and the third wheel is engageable with both the work support surface member and the base. ### Claim 8 (depends on 7) The saw system of claim 7, wherein: the base defines a first guide slot and a second guide slot; the third wheel is engageable with the first guide slot; and the first wheel is engageable with the second guide slot. ### Claim 9 (depends on 8) The saw system of claim 8, wherein: the second guide slot includes a first portion with a first diameter and a second portion with a second diameter; the first diameter is larger than the second diameter; and the first wheel is engageable with the first portion and the second portion. ### Claim 10 A saw system, comprising: a base; a tile saw power head assembly supported above the base and defining a cutting axis; a first wheel engaged with the base; a work support surface member defining a horizontal work piece support plane and movable with respect to the base along the cutting axis; and a second wheel engaged with the work support surface member, wherein the first wheel and the second wheel support the work support surface member above the base and are axially movable with respect to the base and the work support surface member along the cutting axis, and are used to move the work support surface along the cutting axis with respect to the base. ### Claim 11 (depends on 10) The saw system of claim 10, wherein: the first wheel is engageable with the work support surface member; and the second wheel is engageable with the base. ### Claim 12 (depends on 10) The saw system of claim 10, wherein: the first wheel defines a first axis of rotation; the second wheel defines a second axis of rotation; and the first axis of rotation is located in a plane that is vertically higher than a plane in which the second axis of rotation is located. ### Claim 13 (depends on 12) The saw system of claim 12, wherein at least one of the first wheel and the second wheel is engageable with a first rack attached to the base and with a second rack attached to the work support surface member. ### Claim 14 (depends on 10) The saw system of claim 10, further comprising a carriage body, wherein: the first wheel is rotatably supported by the carriage body; the second wheel is rotatably supported by the carriage body; and a third wheel is rotatably supported by the carriage body. ### Claim 15 (depends on 14) The saw system of claim 14, wherein each of the first wheel, the second wheel, and the third wheel is engageable with both the base and the work support surface member. ### Claim 16 (depends on 14) The saw system of claim 14, wherein: the first wheel is engageable with the base but is not engageable with the work support surface member; the second wheel is engageable with the work support surface member but is not engageable with the base; and the third wheel is engageable with both the work support surface member and the base. ### Claim 17 (depends on 16) The saw system of claim 16, wherein: the base defines a first guide slot and a second guide slot; the third wheel is engaged with the first guide slot; and the first wheel is engaged with the second guide slot. ### Claim 18 (depends on 17) The saw system of claim 17, wherein: the second guide slot includes a first portion having a first diameter and a second portion having a second diameter; the first diameter is larger than the second diameter; and the first wheel is engageable with the first portion and the second portion.
