## Abstract

A turntable in modular pie or other sections, which sections can be added or taken away in concentric rings from a base version of the turntable in order to scale the size and capacity of that turntable to accommodate a wide range of size and loading needs.

## Claims

### Claim 1

A method of assembling a turntable comprising:
providing a hub defining a first rotation axis;
providing a base including a plurality of rolling supports that each rotate about one of a plurality of axes of rotation perpendicular to said first rotation axis, said base including a plurality of base sections;
securing a rotating member to said hub such that a center of said rotating member aligns with the first rotation axis, said rotating member including a plurality of sections;
positioning a first one of said plurality of base sections radially around said hub, the first one of said plurality of base sections including a first set of the plurality of rolling supports;
coupling a first one of said plurality of sections to the hub that defines a center of said rotating member, said first one of said plurality of sections supported by the first set of the plurality of rolling supports and defining a first radius;
securing a second one of said plurality of base sections radially outwards of said first base section, said second one of said plurality of base sections including a second set of the plurality of rolling supports; and
securing a second section around said first section and supported at least in part by said second set of the plurality of rollers to define a second radius greater than the first radius.

### Claim 2 (depends on 1)

The method of claim 1, further comprising securing a plurality of pieces to each other to create the first section.

### Claim 3 (depends on 2)

The method of claim 2, wherein the securing includes removably securing.

### Claim 4 (depends on 1)

The method of claim 1, further comprising securing a plurality of pieces to each other to create the second section.

### Claim 5 (depends on 4)

The method of claim 4, wherein the securing includes removably securing.

### Claim 6 (depends on 1)

The method of claim 1, further comprising securing a plurality of parts that to each other to create the first one of said plurality of base sections.

### Claim 7 (depends on 6)

The method of claim 6, wherein the securing includes removably securing.

### Claim 8 (depends on 1)

The method of claim 1, further comprising securing a plurality of parts to each other to create the second one of said plurality of base sections.

### Claim 9 (depends on 8)

The method of claim 8, wherein the securing includes removably securing.

### Claim 10

A turntable comprising:
a hub defining an axis;
a first section having an outer edge and a center aligned with the axis, said first section affixed to said hub;
a second section having an inner edge, the inner edge configured to fit around the outer edge of said first section, said second section removably secured to said first section such that said first and second sections are rotatable about said axis; and
rollers positioned below a bottom surface of said first and second sections, said rollers supporting said first and second sections to enable rotation about said hub axis.

### Claim 11 (depends on 10)

The turntable of claim 10, wherein said second section is configured to be arranged concentrically around said first section.

### Claim 12 (depends on 10)

The turntable of claim 10, further comprising a base having said rollers secured thereto.

### Claim 13 (depends on 12)

The turntable of claim 12, wherein said base is comprised of a plurality of pieces, each including a plurality of rollers secured thereto.

### Claim 14 (depends on 13)

The turntable of claim 13, wherein a first set of said plurality of pieces corresponds to said first section and a second set of said plurality of pieces corresponds to said second section and the second set of said plurality of pieces is configured as a concentric ring around said first set of plurality of pieces when said first and second sets of said plurality of pieces are assembled.

### Claim 15 (depends on 14)

The turntable of claim 14, wherein the first set of said plurality of pieces has a center which aligns with the axis.
