Looking to brainstorm about a Jacob's Ladder-style prop weapon - Grendel's Fork Answered
I have a friend who is a big fan of Matt Wagner's Grendel comics, and I thought it would be fun to make him a prop version of Grendel's signature "fork" weapon. I can handle the construction of the staff and the blades, but I'd like to get some thoughts about the special effect - a Jacob's Ladder-style electrical arc between the blades. Obviously, I'll need to modify the pictured design a bit so that the blades are electrically isolated from each other - no "tuning fork" configuration.
My first thought was to just get a commercial "stun gun" and attach one contact to each blade, but I'm hoping the 'ibles community can help me come up with a better idea.
Hollow, black anodized metal staff. 6' length, 7/8" ID. Separates in the middle via a screw-threaded coupler. Has a threaded socket in one end and a black plastic plug in the other end. (It's an extra upright from a utility shelf unit)
Blades - not purchased yet, most likely 440 stainless tanto blades (dulled) 7" to 10" plus a 3" - 4" tang.
Unit must be self-contained - no power cord visible i.e. to an external battery pack or wall wart. A removable recharging cable would be OK.
Arcing must be triggerable via a switch on the staff.
I don't need to actually shock anyone, I just want a flashy visual effect. Simulated arcing would be perfectly fine as long as it looks good.
Needs to be sturdy and fairly impact-resistant. It won't really be used as a weapon, but it will undoubtedly get played with a lot.
Anybody have any suggestions?
