Tiger Siren Caution
The gaffer tape is no joke.
I mounted my Tiger Siren replica from Kansas Jack to my Schwinn Speedster, and then headed out for the bar that night. One block from the bar I hit a pothole and then SNAP! the tiger head was flying through the air.
Luckily the mic was attached to the handlebars, and the mic cord acted as a bungee, but the bottom of the siren is all cracked and the mic is pulled clean from its socket.
If anybody is mounting a resin tiger siren, I recommend you reinforce the inside of the box with a ring of fiberglass or some kind of extra support. That's what I plan to do when I glue mine back together. The mounting plate overkill used on P.W.s bike is there for a reason!
Also, regarding tiger heads, I've noticed that the tiger head was re-sculpted for the movie - they built up the cheeks, extended the sides of the white snout wider, and built up the eyebrows. Also, the teeth are crooked. Maybe they cut off the teeth, sloppily cast the resculpted head toothless (one for each bike) and then glued on teeth that were cast separately. I didn't notice all this until I tried to paint my tiger head to match a screen grab.
