Goals

Torch table using standard flat bar and angle iron for structural support. borrowing electronics from D3D CNC Torch Table.
Possibly use multiple ball bearing rollers with spring support to tolerate debris on bar surface
3D printed mounting points that minimize drilling/welding

1/4" x 6" x 9' Flat Bar - discount steel
1-1/2" x 1-1/2" x 1/8" x 9' Angle - discount steel
R6 Ball Bearing - grainger

Belt - GT 2mm pitch x 6mm wide Biedlers Belts
Sprocket - GT2 2mm pitch x 6mm wide x 20 tooth E3D store 2D Drawing

Mcmaster doesnt seem to carry GT belts? but the have other sizes.
- GT seems to be popular size with 3D printers for some reason

Perhaps a wider belt should be investigated for higher torque
