Frequently Asked Question number two:

I've got this pinball machine.  Now what do I do with it?  (Besides
play it, of course!)

=========================================================================
=======================      Playfields         =========================
=========================================================================

Playfields come in three flavors:  Mylared, non-Mylared, and Williams'
"DiamondPlated" fields.  Mylar is a sheet of clear plastic laid over
the playfield to protect it.  Mylar can get grubby, and slows down play...
Some pinball purists remove the Mylar and keep their fields well waxed.

For Mylared playfields, you can use "Endust" or something similar.  If 
your game is already in good condition, it does just what you want, and 
without that annoying waxy buildup!  

Williams field service suggests cleaning DiamondPlate playfields with
Novus Plastic Polishes #'s 1 and 2.  #1 to clean and repel dust, #2 to
remove fine scratches.  Or you can simply wipe the field clean with a rag
and some glass cleaner.  KIT carnauba wax is also reputed to be good.
Call Novus at (800) 548-6872 for a distributor in your area.  Brady
Distributors (see bottom of FAQ) and some plastics supply houses carry Novus. 

By the way, Williams does not recommend "Wildcat" wax on DiamondPlate
playfields, as it can seep under any mylar pieces and dissolve their 
adhesive.  It can also cloud clear ramps, with repeated use.

Maintaining your non-Mylar playfield is more complicated.  There are special
waxes made for this, such as "Mills" and "Wildcat," which are available
at distributors or via mail-order.  (See list of suppliers below)  Wax 
protects the playfield's paint, and provides a smooth, fast, surface for
the ball to roll on.

A dirty playfield should be "dry wiped" with a soft rag before the first 
cleaner/wax application -- that much less dirt to get trapped in the wax.
Do NOT clean playfields with water!  Lemon Pledge is reputed to be an
excellent general-purpose cleaner; you can also clean up the playfield
plastics with it, and use it to freshen up a game that's alread got a
good coat of wax.

If you want get ambitious and remove your Mylar, Brian Millham
(bdm@druwa.att.com) offers the following advice:

	"It turned out to be a BIG, MESSY job, but it was worth it!
	The best method that I found was HEAT.  I simply took a hair dryer
	and heated up a portion of the Mylar, starting from an easy to get
	to edge, and peeled it up.  Once you get it started, the job is fairly
	easy, but slow.  Let the heat do its work.  Don't overheat the
	playfield, but also don't pull the Mylar up too fast.  You don't want
	to pull up any paint with it!

	"Once you have removed the old Mylar, you are probably only half done
	with the job.  You now will need to remove the glue that was left
	behind.  This is the fun part :-)  I ended up using Milwax and
	lots of elbow grease.  Once you start cleaning off
	the glue, you will find that it looks like you are making a bigger
	mess than you had.  Don't worry, it will start coming clean.
	Oh, did I mention to have LOTS of cloths to do this part?

	"It played like a whole different machine!  And it looked better too.
	The Mylar leaves a dull finish.  A waxed playfield looks nice and
	bright.

Also, there are solvents available to dissolve the glue...I've seen these
work with magnificent results.  Michael Knudsen (knudsen@ihlpl.att.com)
reports:

	"I just heard from a serious pin restorer that that Blue Stuff
	(called CP-100 by Gemini Inc in Michigan) really dissolves that
	gunky glue that holds down Mylar sheets.  Not only cleans it up
	in short order, but will even soak under the edge of a Mylar sheet
	(like around a bumper or ramp) and loosen it right off the playfield!
	So now The Blue Stuff has its special niche in pin work.

If you want to do playfield touchup, you can use Testor's paint.  You'll 
find this in the plastic model section of your local toy store.  Lettering 
can be either retouched by hand, if there's enough to salvage, or completely
redone with rub-on letters.  Art supply stores have the latter.
Before retouching the playfield, be certain to clean well and remove all 
the old wax!  Brian Casper has used grain alcohol with good results.

You can build up height in worn or chipped spots by using multiple coats
of paint.  Be sure to allow plenty of time for each coat to dry, and finish
up with coats of polyurethane spray.

Deeper gouges and holes in your playfield can be patched with "Bondo," a
product typically used for repairing car bodies.  Bondo should be applied
to the bare wood; beware of getting it on playfield plastics, as its
solvents may attack them.  It is very hard after it cures, so you should do
as much shaping of the area as possible while it is still malleable.  Once
it dries, you need to use a power sander to smooth it out.

To fill in stripped screw holes and the like, you can use "Plastic Wood"
to provide a new surface for the screws to grip.

=========================================================================
=======================        Flippers         =========================
=========================================================================

If your flippers seem feeble, have a look at the contacts on the buttons
and the coils themselves.

The flipper coils are actually two coils in one.  One is the relatively
high-current one to initially fire a flipper, and the other is the lower-
current one for holding a flipper up.  If the contacts on the end-of-stroke
switch by the coil are bad, the high-current coil won't fire.  The flipper 
button contacts supply both coils.

Cleaning and adjusting these contacts will fix many flipper problems.  See
the directions for contact cleaning under "General Cleaning Tips" below.

A sluggish flip may also be caused by a dirty flipper sleeve.  Remove
the sleeve and clean it and the plunger.  A melted sleeve should warn
you to check the EOS switch and make sure the high-current coil is cutting
out on cue.

You may also have a worn coil stop or plunger, causing the flipper
to pull in too far.

If you need new contacts, sleeves, or whole coils, you can order
replacements from the sources listed below.  

Flippers in many electromechanical (EM) machines are driven by AC, so there
tends to be some buzzing associated with them.  This is normal.

=========================================================================
=======================     Drop Targets        =========================
=========================================================================

To clean drop targets, hold the target up by hand, or remove it entirely, 
and use a moist soapy rag or Q-tip.  Anything nastier than soap may harm 
the paint or plastic.  Again, test on an inconspicuous place first.

If your drop targets aren't resetting properly, check to see if the
lip the target sits on is rounded off.  If so, file the plastic lip (on 
the target) flat again or replace the target.  Also, check that the reset 
solenoid is pulling in all the way so that the targets are coming up to 
the correct height.

If the targets don't register when they drop, try cleaning the contacts
as described below.

=========================================================================
=======================  General Cleaning Tips  =========================
=========================================================================

If this is a machine you've just bought, by all means vacuum out all the
insides, carefully.  Watch out for the various service instruction sheets
stapled around the insides.  If you find any mouse droppings, check carefully
for wires and cables gnawed thru so neatly that you can't see the gaps!

Radio Shack Color TV Tuner Cleaner is a good all-around cleaner and
lubricant, even for non-electrical items like solenoid plungers and
shooter plunger shafts.  Don't get it all over the playfield though,
as it's conductive and can confuse a solid-state machine.

Intermittently flickering bulbs may be helped by bending the socket
slightly out of round with needlenose pliers (with the bulb out!) to make
the grounded shell fit tighter.  Use TV tuner cleaner to slip the bulbs
in and out easier.

You can use a business card to clean switch contacts.  If necessary, 
use Freon, rubbing alcohol or some such solvent on the card to soften 
the crud, and use a dry card again afterwards.  High-current contacts,
such as the ones on flipper buttons, may require harsher measures.  Look 
for a "contact burnisher" at your electronics shop or hardware store.
Never use these on the gold-plated low-current contacts, though, as
they'll destroy the plating and lead to corrosion.

If some switches aren't firing, or are firing sporadically, check the 
spacing between the contacts ("Dwell and Gap").  Bally recommends
1/16th of an inch.  You can adjust the spacing by bending the stiff blade
that's between the two conductive ones.
