Orbit Diverter Pin

Orbit Diverter Pin fix is thanks to a post by MHS on RGP :
"You can also put a washer or two under one of the screws underneath the playfield holding the post diverter behind the orthanc tower to tilt the diverter forward father into the lane and make it more effective.  (Solves the problem of right orbit shots during War of the Ents coming back around the left orbit to the flipper.)"
Armed with this information, here’s what I did:
Took off the orbit pin diverter (3 screws) and then adjusted the stop so it was up a bit more. It was factory set to be below the height of the playfield. The screw post was glued (or held with locktite), so the only way move it was to add an 8/32 locknut to the bottom thread. Tightened it against the original nut which I had backed off to my adjustment point. Then I could screw both nuts back in place. Just left the locknut there.

Putting the diverter back, I added a small washer (as suggested) under the screw farthest forward towards the flippers to angle the diverter as above.  Tip:  I have also read on RGP that a "post bead" (like under the GI sockets) works well and makes it more adjustable.

You need to check that the diverter is not binding over the length of the full stroke, by activating it by hand. Also check that the "orbit pin" works from diags:coil test #13 with the playfield down,
as the coil plunger tends to bind on the harness wires on my LE game.

I got asked this question before and suggested to try tweaking the rollovers / when switches activated. I did warn not to change anything if it was working (at all) as it might get worse.

Maybe sometimes it's a ball speed problem, where the ball is just travelling to fast to be stopped by the orbit pin. But that's a guess. ested in the depth

This seems to be a better solution to the problem.  My orbit pin never worked correctly from factory, but seems to be working as it should now.
War of the Ents shots can be made from both orbits correctly.
Don't need to use the "front door" of Orthanc to score a hit anymore.  "Release the Dam"!

Backed out more mods: Sword lock.

Seem to be backing out changes I made! Removed the extra rail on the left of the sword lock.  My wife was complaining that it was shifting on the axis of the hole in the middle, and causing a ball hang and search.

I confirmed that the double sided tape was starting to let go. One possible solution would be to drill holes (don't like doing that) or to stick it in place more permanently with epoxy or museum putty.

Removing the extra guide completely and bending the ball lock coil bracket slightly left, which I was told (by Steve Marsh again) seems to work just as well so far.  Sometimes simple is best.
