Introduction Edit

The entire triggering mechanism in cheiroballistra is fairly vaguely described. Still, this method is most likely not the one used in antiquity, and there are more authentic methods. This method is presented here as it's still useful if one is not aiming at historical accuracy at all costs.

Making the fork Edit

Attach a thick but relatively narrow piece of steel to a vise so that half of it below the jaws and the other half above them:

Making the fork - 01

Next bend the piece into 90 degree angle cold and detach it. Heat the bent area with a blowtorch:

Making the fork - 03

Bend the heated are to full 180 degree angle with a hammer:

Making the fork - 04

Attach the fork upside-down to the vise, leaving just enough above the jaws to allow forming the U-shaped part on the top:

Making the fork - 05

Use a flat screwdriver or a chisel to force the sides of piece slightly open:

Making the fork - 06

Continue by opening up the sides completely into 90 degree angle:

Making the fork - 07

Place a appropriately thick piece of steel on top of one jaw of the vise, the idea being to make the next bends at correct distance from the tenon part of the fork:

Making the fork - 08

Heat and bend to 90 degree angle:

Making the fork - 09

Attach the other side to the vise:

Making the fork - 10

Heat and bend to 90 degree angle. You probably have to remove the fork from the vise at to make the finishing touches using other methods. You should end up with something like this:

Making the fork - 11

Making the fork - 12
