Quoted from Pinball-Pat:
Hi guys, my new RRWOZ is up and playing 100% One little tweak I had to make was to my "Left" haunted tree. It seemed to be clashing with the PF guide under the playfield. The tree was hitting something making a metallic sound and not going down. I shimmed up the left mounting screw of the tree pop bumper with 4 flat washers, this tipped the guts of the tree to the inside of the cabinet and it now clears the rail. ***I am guessing it was the guide rail, couldn't really see.
This happen to anyone else, any different solutions?
This has been noted a couple times. Its a very packed close area around the pops.
The guide rail can be loosened and moved/bent out of the way.
In extreme cases remove the tree, its easy.
The trees are hollow rubber, just push down on a hollow nut driver to grab the nuts.
Remove the pop bumper ring (its really easy) and grind off enough of it so that it doesnt rub in the area you need.
It doesnt have to be round there. Flattening if off is ok as the ball cant hit it there anyway.
You can use a dremel, file, grinding wheel or coarse sandpper on a sanding block for this. Its a thin soft steel ring designed for easy replacement and adjustment.
This happens mostly on the ball guide of the crystal ball loop and sometimes on the far left guide rail in the haunted forest.
Putting in the washers is great but I worry that the crooked mech will damage the playfield in time.
