Jones Pinball Machine
our summer vacation
in Aruba one year, the kids played on an Indiana Jones
machine at a Pizza Hut. They liked it very much, and I
started to consider it as a candidate for my second pinball
machine. After a few months of casual looking, I found one being
sold by a dealer in Northern
Virginia. The machine was very dirty when I
bought it. It was unshopped, the rubbers were broken, and
barely playable. However, I could tell that the plastics, the
playfield and the electronics were in excellent shape, and with an
investment of my time, I could restore the whole machine.
first stripped the playfield of all parts, and cleaned and waxed the

above picture shows the upper part of the playfield after
reassembly. It took about 9 hours of work to get to this
point. Some steps that were done:
three and one bank targets were dismounted, disassembled, completely
cleaned, new NOS target decals applied, and new coil sleeves installed.

experimented with various methods to remove the caked-on dirt that was
on the playfield. I tried water with a sponge, Novus 2, and
Alcohol (IPA) with Magic Eraser. As can be seen in the above
image, the clear winner was Novus 2. The water hardly made a
dent in the dirt, and the IPA did a little better. The Novus
2 was amazing as it dissolved the tough dirt, forming a brown mud that
I could wipe off.
The plastics were in great shape except the two slingshot
plastics. Amazingly, I found a
new and unused set inside the cabinet while I was vacuuming it
out. What luck!
After I used Novus 2 on them, they looked like new. They are
normally about $25.
When taking the parts off, I laid them out in the same general way that
they are originally
located. This allowed me to find the parts later.
Note the double amount of sling plastics.

plastic in the foreground is commonly broken.

the idol ruins
common problem on these machines is the condition of the idol ruins on
the right hand edge of the playfield. They often crack as a
result of stress such as from ball strikes. Mine was no
exception. I repaired them in a manner similar to the way I repaired
plastic ramps on my Space Shuttle.
Original condition of one of the idol ruins. Missing part
around the mounting hole,
and a crack at the hole for the flashing light.
repairing the cracks, the shell of the ruins felt much stiffer and
stronger. I then mixed up some acrylic paint and touched up
the area. The main body color was mixed from
orange-brown-white, while the rock accents were brown. After
the touchup, the repairs blended in well with the original area.
The repairs were made with epoxy and fiberglass tape. After
painting, the repairs
are difficult to spot.

Almost like new.

I bought a chromed gun that came up on Ebay. Click here for a picture of
the pre-cleanup state of the original gun. After tumbling,
the original cleaned up nice, but it still had rough surfaces right
where the palm rested.
The new gun handle. Shot without flash and long exposure time.
The unit is very shiny, and should last a long time
in a home environment.

to replace the one I already have as it has some scratches.
This was the seller's note to me as to the origin of this rare item:
Hi Jim here,
My parents had a friend that worked for Williams arcade, and they just
used to give them to the employees. They gave it to me and i have had
this for years. I have not done nothing with it since i have owned it.
and figured that some one else might be able to get great use of it.
enjoy and thanks Jim

to hit the POA entrance: I had the incorrect coils on the machine. They are supposed to be
FL-11629, but I had FL-11630s on the machine.
More info on the coils here. I found an unused FL-15411
in my stock, and installed that one.
Results are noticeably better. The data
below from is from weakest to strongest. From here.
used for small flippers, like the "Thing" flipper on Addam's Family.
9.8 ohms/165 ohms. Usually a yellow coil wrapper.
used for weak flippers, like Twilight Zone's upper right flipper. 6.2
ohms/160 ohms. Usually a green coil wrapper.
"standard" flipper strength, as used on older games like Earthshaker,
Whirlwind, etc. 4.7 ohms/160 ohms. Usually a red coil wrapper.
: strong flipper, as used for main flippers on Addam's Family, Twilight
Zone, etc. 4.2 ohms/145 ohms. Usually an orange coil wrapper.
strongest Williams flipper. Used on most of the newest WPC games. 4.0
ohms/132 ohms. Usually a blue coil wrapper.
