How much is this mod? I’m sure it in here somewhere but I’m an idiot. My LE will be here in about 2 weeks. Sounds like this might be worth blowing some cash on.

Quoted from harryhoudini:

1. We ran out of Lexan lids and I didn't want to place an order considering how few people there are probably left who have a POTC and want to do this mod. We did a pretty significant amount of the total game sales.

My POTC arrives in a week or so. I will be buying this mod. Is it still available with all the new upgrades and changes?

A little trouble after install. See enclosed videos in 2 parts.

Basically the rod seems to be interfering with the 'gate' and the coil assembly. The rod is pressing on the little tab and not allowing the gate to open all the way to release balls. Also, the tab seems to mechanically hold up the lid about 1/8" or so intermittently. I hope these vids help.

Well, I shortened my rod a little by screwing the rod itself more into the yellow sheath. I played around with a couple of different things. When I first put lid on, it opened and shut very well but the balls would not release at all from the trunk as I previously showed in the video.

I played around with the position of the rod a little and if I install it on the lower arm of the motor the lid still opens some and shuts perfectly. The balls will release but just barely. The first one will release after a couple of pulses of the magnet and maybe a little shake of the pin. The next two will come out simultaneously with a little nudge timed with the magnet. I'll take another video later. I am tempted to gently bend the arm out a little to get a little more clearance but certainly afraid of breaking something. Additionally, if I do that the ball will show a little at the edge of the chest when locked.

Not a great solution. Getting ready for a teleconference at work. Will video after.

Here are a couple more videos of my partially working chest mod:

Video with rod behind the tab:

Video with rod in front of the tab (I mis-spoke at the end. Clearly the rod is in front of the tab)

I hope this helps me trouble shoot my issue. I can take other photos/videos by request if someone needs to see something specific.

Well, for now I believe I got mine Working acceptably. You can see how my arm is somewhat in between vertical and horizontal. Also, I tightened down the screw holding the solenoid magnet that opens the chest door. It was a little loose and I think that was part of my issue with the door not opening.

Yeah, now time to really explore all this game has to offer! A do have a few more non pressing issues with the game which I’ll post on the other thread. They don’t affect game play so not as concerned on those.

Also, not shown in above photo, my flex rod is in front of the tab, mot behind
