Introducing
Prometheus
Overhead Boom Arm for Workshop Dust Extractors
Prometheus:
The Greek Titan of forethought,
responsible for bringing civilization
 to mankind for the arts, sciences,
 metal working, and woodworking.


With the Prometheus Boom Arm, RTS Engineering brings some civilization to the workshop. The articulating arm can be positioned over any point within a 6-,8-, or 10-foot semicircle of the base, and can even track along with your tool's movement as you process the length of the workpiece. The upper channel provides for dust extraction at your work area, while the lower channel may be used for other energy sources, such as compressed air, vacuum clamping air, electrical power, welding lines, or any other type of energy conveyance you may need.
Contents:
Prometheus contains the main boom arm, a supply-side 8-foot anti-static vacuum hose, and 2 hose clamps for securing vacuum hoses (clamps for both supply and tool hoses). It does NOT include the green tool-side vacuum hose, nor mounting hardware. The clear, supply-side hose (Included) fits into your Festool CT-vac (and most other shop vacuums). The original hose from your shop vac (not included) fits the end of the Prometheus Boom Arm.

Options:
  • RM-70: Approximately 70-inch (6-foot) boom reach.
  • RM-100: Approximately 100-inch (8-foot) boom reach.
  • RM-120: (Shown below) Approximately 120-inch (10-foot) boom reach.


Installation Notes:
Prometheus mounts to a reinforced wall. Because every building structure is different, you must consult with a structural engineer to determine your specific mounting requirements. The buyer assumes all responsibility and liability for ensuring proper installation and the structural integrity of their building structure.
The diagram and table below shows the basic force diagram for Prometheus on a typical 8-foot wall.

  • Install the main mounting bracket directly to structural materials, without having drywall or other friable materials in between. (i.e. remove all drywall behind mounting bracket.)

  • Sister framing members as necessary to provide a solid mounting structure. Use through bolts, washers, and nuts to bond the sistered members together. Do not mount the boom arm to a single stud.

  • At a minimum, it is recommended to install corner brackets to the top and bottom of vertical wall members, securing them to the top and bottom plates. (i.e. do not rely on toe-nailed fasteners for studs.)

  • Minimum wall bracket fasteners should be 5/16 x 3" lags screw, or 5/16-through bolt, washer, and nut. You must use all 6 mounting holes.
Sample Installation:
The following is a sample installation performed in my own garage, and should not be considered as installation advise or directions for any other installation. The wall structure is 2x6 construction with a double top plate. A pair of 2x10 plates were secured to the existing wall spanning 3 studs and included lag screws into the wall's top plate. Prior to installation, carriage bolts were installed through the back of the 2x10 wall plates, such that the Prometheus wall bracket could be secured with nuts and washers. (Some of the lag screws are concealed behind the steel wall bracket.)
