I just finished restoring a Banzai Run for Modern Pinball NYC and in moving it out of my shop to make way for the next machine I had to lower the head to clear the doorway.
Then it happened the Unthinkable. I forgot to raise the ball carrier in the Upper Playfield before lowering it and snap.
The motorcyclist in the upper playfield dropped to the lower playfield.
In other words in an instant the entire machine was now just a pile of parts.
Those that are familiar with Banzai Run know the significance of the the Ball carrier. Without it there is basically no game.
The part is of course unobtainable and is made of plastic.
This is a must remake part for Planetary Pinball as there may be many machines down just because of it being broken.
It had snapped cleanly in two in a vertical line just past the half ball shapes on the assembly as can be seen in the parts page. Part #4 or 03-8159
The part has to hold a good amount of weight (Coil for Magnet +weight of ball) while moving on its lifter screw with lots of vibration etc yet the broken surfaces to be mated are very small.
Tried various epoxies to no avail as the cured form (after 24hrs) just flakes off and does not adhere, even Plastic specific epoxy had the same result.
Turns out as a last resort in the adhesive plan A anyway (Plan B use metal to fabricated a form of bridge) I came across Locktite Plastics Bonding System
Within 30 seconds it appeared to be holding the halves together with force.
I installed it back into the machine and so far after 20+ cycles of the assembly it appears to be working great.
Very impressive if you visually knew the part shape what it does and the surfaces where it was rejoined

So far so good but only time will tell.
Just thought I would post this so other BR owners may have a way to save their machines.
According to the Loctite instructions its good on Plexi and poly so this may be the bet ramp repair adhesive around.
I don't have any damaged ramps to try it on.
I will give a follow up as to the BR results after the machine has been brought to Modern.
