TableTop Siege

** DRAFT **
Table Top Competition Rules

Here are the Table Top Siege rules put togeather by the Siege Guild Master and the Deputy Earl Marshal for Siege. The rules cross the dual goals of the guild to both promote the A&S aspect as well as the combat aspect of Siege, while keeping the bystanders safe and the competition fun for all. While we can not require the use of these rules, by building a standardized Table Top rule set the hope is that more engines will be built as they should be able to be used at more then one event.


  1. Engine Construction:
    1. All engines must be of a period design and appearance. Period materials should be used where possible as safety permits.
    2. Minimal Documentation is required in the form of a single period picture, be it an illumination, painting, or sketch to show that the engine is based on a period design.
    3. Engines must be constructed to scale, however that scale may be rough rather then exact.
      • Example: When using 1/4 scale, a 2"x6" (which actually measures 1.5" x 5.5") when scaled down could use a typical 1/2" stock material (which is also thinner then actual size).
    4. Each engine must fit inside a 24 inch cube at some point during its normal firing movement.
    5. All ammunition will be:
      1. Single tennis balls for "rock throwers". Tennis balls must meet regulation specifications and are recommended to be "day-glow yellow" or "blaze orange" in color for maximum visibility and may not be altered in any way, however the ball must be "popped" by drilling a single 1/16 to 1/8 inch hole.
      2. Special golf tube shafted bolts for "arrow shooters' constructed as follows:
        1. Shafts may only be constructed using unreinforced golf tube.
        2. No metal, wood, or other hard material may be used in the construction of the munitions.
        3. All bolts are to have a maximum length of 18 inches from head to nock.
        4. The head must be constructed in one of the following manners, regardless of which the head must be firmly attached by the use of tape and/or string.
          1. Rubber stopper - A rubber stopper, size 6.5, is placed in the end of the tube such that it enters the tube at least 1/2" and is well attached. Resilient padding of between 1 and 1 1/4" long after taping is then added on top of it. The head must also have a side-wrap of foam that extends from the tip of the padding to at least 1/2" over the rubber stopper to bring the total diameter of the head to at least 1 1/2" after taping.
          2. Balder Blunt - Balder Blunts may be used by cutting the support fins away so that the blunt slides over the golf tube and attached securely. Between 1 and 1 1/4" long of resilient padding, after taping, must be added to the tip the diameter of the foam. After taping must be at least 1 1/2" in diameter. Any classic style of Balder Blunt can be used in this manner, whether 1 or 2 piece mold or designated for fiberglass or wood.
          3. Tennis Ball - A tennis ball is placed at the end of the tube and attached via tape and/or string. The ball must be "popped" by drilling a single 1/16 to 1/8 inch hole.
        5. The nock (the end in contact with the string) may NOT be modified in any of the ways typically used in combat archery. It is only to be taped around it's circumference with no more the 2 layers of string or duct tape in order to remove any sharp edge which may cause damage to the bow/prod string. This tape may not extend more then 3/4" down the length of the golf tube shaft inside or out.
        6. All bolts are to possess a minimum of 2 uncut feathers (fletching) made of 3mm craft foam. Each must measure at least 5 1/2" long and 2" in width.
        7. All bolts are to be 100% orange in color to prevent any potential confusion or accidental interchange with Combat Archery or Siege ammunition. This it to be accomplished on the shaft with a single layer of orange tape only. Heads and fletching may be taped as per standard combat rules allow.
    6. The ammunition may not be altered in any way prior to shooting, and will be provided by the competition sponsor. The sponsor should advise at the time of the competitions announcement which arrow thrower ammunition they will be providing to allow arrow throwers ample practice time with their engines. The above rules for construction are provided for the sponsor to make competition ammunition and so the operators may construct his/her own ammunition for non-competition use.
    7. All engines must be constructed in such a way as to be secured when not in use. Simple locking methods may be used instead of "deconstructing" your engines. This does not mean you have to pad lock the engine. For the safety of those in the surrounding area in the event unsupervised actuation is attempted, an un-attended table top engine must be rendered safe just like the field units. Despite their size, these engines are dangerous!
      • Examples: Apply a U-bolt clipped around both the arm and an non-mobile portion of the frame, unstring ballista, remove all ballast from trebuchets, unwind skeins in catapults, even a simple well-placed zip/cable-tie is acceptable.
  2. Competition & Judging:
    1. Scenario and prizes are left to the sponsors discretion. Just try to keep all engines in mind when you develop the scenarios and try to keep any one from having a significant advantage.
      1. Scenario Thoughts: Do not allow arrow and rock shooters to compete in straight forward distance and accuracy shoots as arrows are more aerodynamic, they fly further and straighter giving them an advantage. If you do not have enough entrants to have separate courses, design a course that will not favor one engine class over another. (Reference the concept of archery shoots designed not to favor a crossbow over a hand bow). The extra power that an arrow thrower possesses could be made to work against it a properly designed course. Obstructed targets are easier for rock throwers to hit, while "line of site" targets are more so for ballista. The course could be made to incorporate a relatively equal number of line of site targets as obstructed ones. Try partial obstructions as well, perhaps make the walls height just enough where a well crewed ballista can skim a bolt over it and still hit the target. Or construct some to take damage so a shot or two could be sacrificed to obtain a direct hit later. Also, mix the type of targets given. Vertical targets are easy for a ballista to hit, and difficult for a rock thrower to hit. Inversely, horizontal ones are easy for rock throwers, and difficult for ballista. Adjustable target facings might be a good option. If one round favors a specific class of engine, tilt more facings either horizontal or vertical to offer the other engine classes a chance to catch back up. Remember, the spirit and ultimate goal of these suggestions is to let all engines compete in one match and on an equal footing.
      2. Suggestions: Define how the shoot will be done ahead of time, example; from a table or from the ground, and inside or outside. All engines should be fired from the same table/platform/position to eliminate possible location / placement "advantages"
    2. Judging method is left to the sponsor. Do your best to compose rules that do not favor any class of engine allowed.
      1. Suggestions for prizes categories:
        1. Longest
        2. Most Accurate
        3. Best on the course (remember the idea was to have different shoots just like archery)
        4. Best Display & Documentation.
    3. Team entries are more than welcome as it takes more than one to crew a combat engine (one engine per crew).
