SOMETHING
NEW, SOMETHING
CHROMED... It takes countless
hours of pushing and pulling, but your bike is poised in
direct view of the television. Despite your chiropractor's
warnings, you kink your neck, so you can watch Speedvision
through the gap between the absent airbox and the frame.
This position causes you to walk like an Egyptian for the
first four hours after the morning wake-up call, but you
don't care. You get to watch your bike in front of other
bikes. Besides, your neighbor thinks your new strut is
sexy. After the 100th
wash, wax, polish and buff, you rewire the living room to
accommodate a light show pulsating to the beat of your
favorite motorcycle song. You need MORE shine. You start
cleaning the chain with paraffin on a daily basis (isn't
that the same stuff they spray on apples to make them look
shiny in the grocery store?). You run home during lunch to
remove any dust that may have accumulated since the morning
buffing session. There is so much Windex in your house, that
the state mandates you post a toxic placard on your front
door. But even after gallons of Windex, pounds of Simichrome
and a 1500 watt strobe light, your 20+ year old mount just
doesn't have the same factory shine it once did. Now what?
"RE-CHROME IT," answers a celestial voice accompanied by
wind chimes. "Chrome it all." Uhhhh, okay. Before you grab
your glistening wrenches, you may want to consider a few of
the finer elements of chrome plating. For instance, before
you haul your frozen butt down to the plater with a trunk
full of swingarms, side covers and gas tanks, you may want
to remove all the bolts and washers. The plater will do it
for you, but expect a $60 per hour fee tacked onto your
final bill. So, to avoid the "You gotta be kidding me! What
the hell is that charge ?!" you may want to disassemble and
degrease to the best of your ability. Budget about two to
three episodes of "Renegade" for each piece. What can you
chrome? Well, that depends on you, Mr. Mastercard and the
condition of the piece. The piece must be free from rust,
casting cracks and excessively deep nicks or pits. Remember
the quarter-inch deep gash you made in that rim with the
screwdriver while you were changing the tire? You should
have used a tire iron because you cannot re-chrome that.
Those nasty little pits that remind us how lucky we are to
live in a climate with two seasons (cold and damn cold)? You
can re-chrome those. Decorative
chroming is a three step process. First, the plater buffs
out all the blemishes and applies a .005" copper coating.
Once the copper layer fills in the remaining irregularities,
the piece is buffed to a finish like that of a shiny,
brand-new penny. The luster signals
that the piece is free from major imperfections and ready
for the second step: nickel plating. Nickel plating, as is
all plating, is applied through an electrical process, which
bonds the new material to the original material and
strengthens the bond to the original piece. Plan on the
coating to be in increments of approximately .006 to .007
inches. Lastly but not
lusterly (How could I resist the pun?), the chrome plating
is applied at about a .005" depth. If you use your handy
dandy calculator (Hey honey, how much is...?), you can see
that it is common to have a chrome plated piece become .015
to .020" larger than its original specifications. Is this a
problem? It could be if it were an axle, for example, or
another component that is manufactured to relatively tight
tolerances. I once saw a guy use a hammer to assist in the
installation of a newly chromed front axle. By the time he
got the axle in place, the chrome had fragmented like
chipped nail polish. We all know how attractive that is. Not
that I wear nail polish...anymore...much. How much is this
going to cost? That depends on the intricacy of the piece
and what shape it is in. The actual plating is not that
expensive. It's the hours doing all that buffing that adds
up. The plater has to clean and buff like crazy before and
after the copper is applied. Then, she has to do a final
buff after the nickel and after the chrome. If your piece is
relatively free from imperfections and grease, your bill
will be significantly less than the bill for that chain
guard from your TR6 that has been holding up your bird
feeder all winter. You may want to
check with your chromer before submitting a piece in rough
shape. A lot of these guys have pieces in inventory that are
already chromed&emdash;old and new stuff. You give up your
old piece on trade, and you get the new one. Magic. If you
insist on keeping the original and want your product back by
the time the salt clears, you better get the On Any Sunday
videos out now and start degreasing. Many local chrome shops
are experiencing a six to eight week backlog (Can you say
Harley surge?). What about after
the piece is chromed? Keep it clean and waxed, but do not
use any type of detergent on your chrome. Today's bike
chrome is rated for 5,000 hours of salt water spray, but one
swipe of dishwater detergent can permanently damage it.
Metal platers will forewarn you to take extra precautions
when handling a chromed aluminum piece. This is because the
aluminum core is softer than the applied finish and
therefore an impact with a wrench or a rock may cause an
"eggshell" effect. Always use flat washers under fasteners,
and always keep it waxed. Remember, in
addition to the luster and added strength, fresh chrome
serves an even greater purpose. Take note rockabilly boys
and girls&emdash;you can comb your hair in the
reflection. M.M.M.
