This morning my wife went Black Friday shopping and I decided to see if I could reduce the constant Prison Magnet SDTM shots on my TWD.
It took 8 different setups, but I think I got it. Unfortunately the solution is not universal and the cause and effect is unknown. Here’s the story anyway;
I wanted to see if rotating the magnet and/or having an slight pitch in any direction, had an effect on the ball. I made sure the game was leveled right to left. The pitch is as seen in the photos.
The baseline for how often the ball went STDM on my game was very high, 75% is a conservative estimate. If you didn’t make a move on the game, you were toast.
Rotate the whole assembly 180 degrees.
Magnet is slightly high on the right.
4 SDTM out of 12. 6 out of 12 hit the very tip of either flipper and went down the middle.
Rotate magnet 1/4 turn.
Magnet is slightly high in the back.
8 SDTM out of 8. Yikes
Rotate the assembly 180 degrees.
Magnet is slightly low in the back.
0 SDTM out of 16. After 16 successful attempts in a row, I played a game and realized the ball wasn’t registering shots to the prison off the flipper.
Raise core 1/8 turn, added washer under front right screw to level the magnet.
4 SDTM out of 4
Magnet is high at 2 o clock.
7 SDTM out of 28.
6 SDTM out of 24
Raise the magnet 1/8 turn and add washers to the front 2 screws in an attempt to recreate #3 without as much hop.
Ball hops and doesn’t register prison hits
Attempt #8 Success!C74C756F-BC03-43F5-AAEC-90AA12042EC3 (resized).jpeg
Remove washers. Adjust the magnet back to level. The magnet is slightly high at 8 o clock.
SDTM 2 out of 35 and counting.
