PLAYFIELD MODIFICATIONS

stitch ramp.jpg

The Skill Shot ramp (Launch Tube) is made from

 PVC conduit pipe as shown.

A Dremel was used to cutout sections of the pipe for viewing the ball (the red area).

These are used for the plasma pop bumper mod and the

animated Black Hole mod.

 

The animation motor is removed from the plastic housing and

bolted to the playfield plastic.  It fits in-between the plastic and

the playfield.

The animation assembly was made from 1/16” diameter brass

wire bent into a spiral and fastened to a disc/tube base.

The base attaches to the motor shaft with a set screw.  The objects are fastened to the brass wire.

The objects came from a toy assortment called Space Toob.

The motor fits in-between the plastic and the playfield and is fastened to the plastic with two screws.

There is a second clear plastic under the main plastic that needs a large hole cut out for motor clearance.

A power strip was added in the cabinet to accept

the plasma disc and animation motor transformers.

The large holes in the cabinet are for extra air flow.

The plasma discs are battery operated so they have to be converted to transformer power.  Dummy batteries were made using wood dowels and crimp connectors.  The pop bumper light socket was removed and the new wires fed thru the two holes.  All discs are wired together and go to an under playfield connector.

A 3volt regulated power supply was added.  I recommend using a regulated power supply, not unregulated.

The plasma disc base is attached to the pop bumper body.  The plasma disc slides onto this base and is hidden by a custom paper graphic skirt.

The skirt blends the plasma disc into the pop bumper.
