Old bike often
have more Character and "soul" and are more likely handmade.
Old bikes
have the advantage of being proven in service under the rider the rider
already know he will love the ride over the long term.
Disappearing
building techniques are often more durable.
Steel frame
are more repairable and adaptable than other materials and so can accept
updated hub widths and braze-on configuration others cannot.
An old bike
gains resale value with age, new one loose value dramatically.
Since custom
finishing and modifications are available at CyclArt which are not available
from most manufacturers, we can improve a bike.
We stress
relieve and perform more accurate alignments than most frames are built
with.
Our finish
quality is unsurpassed. (Excuse my boasting!)
CyclArt
has offered complete bicycle frame plating services since 1979.
Here are detailed answers to the most frequently asked questions about
chroming:
What is chrome and how is it done?
“Plating”
as used on bicycles is the process of applying a layer of metal to the
surface of another metal by means of electrochemical attraction in an
immersion bath. Chrome plating is only practical on steel bicycle
parts.
There are
many steps to the process. First, the part must be cleaned of
all paint, grease or other coatings. If the part has been plated
before, the old plating must be removed. This is done by immersing
the part in a tank of acid and “de-plating” by reversing
the current so that metal ions are drawn from the surface of the part
to the cathode in the tank. This process leaves a dull etched surface.
Next, the part must be polished to a high sheen. This is a tedious
and labor-intensive process using powerful lathes and other tools specially
adapted for frames. Few people realize that the part must
fully polished before the chrome is applied. The part must then
again be meticulously cleaned and then can be immersed in the first
of several baths for plating. Most of the actual plating is done
with nickel. Chrome is then applied as a final coat. We then bake
parts to remove any “hydrogen embrittlement” which may have
occurred in plating. Next, masking tape is applied and precisely
cut the areas to remain exposed. We then protect the masking tape
and abrasive blast the area to be painted, “frosting” the
surface of the chrome to increase paint adhesion. After painting,
the making is removed and the edges trimmed precisely with a knife.
The plating
we do is called “decorative” chrome plating and always involves
plating nickel before plating the chrome. The chrome plating in decorative
chrome plating is exceptionally thin, measured in millionths of an inch
rather than in thousandths. It is still a very hard surface, but simple
'anvil' type hardness measurements don't detect the hardness because
the anvil just punches through such a thin coating.
When you
look at a decorative chromium plated surface, most of what you are seeing
is actually the nickel. The chrome adds a bluish cast (filtering the
somewhat yellowish cast of the nickel), and it protects against tarnish,
and minimizes scratching. But the point is, without the brilliant leveled
nickel undercoating, you would not have a reflective, decorative surface.
Chrome plating
is hardly a matter of dipping an article into a tank, it is a long involved
process that often starts with tedious polishing and buffing, then cleaning
and acid dipping, zincating, and copper plating. This may be followed
by buffing of the copper, cleaning and acid dipping again, and plating
in two or three different types of nickel plating solution, all before
the chrome plating is done.
When an items
needs "rechroming", understand what is really involved: stripping the
chrome, stripping the nickel (and copper if applicable), then polishing
out all of the pits and blemishes, then starting the whole process described
above.
Can you just re-plate my chrome without repainting?
It is not
possible to re-chrome a portion of a frame such as lugs, leaving surrounding
paint undisturbed. Partial, or probably complete repainting will
be necessary.
Can I have my frame plated locally, then send it to CyclArt for painting?
A great plater
can do a terrible job on a bike frame unless he has taken the time and
made the investments necessary to address the unique challenges race
frames present. Unfortunately we’have seen many real disasters
when platers not specialized in racing frames are involved. Such
as:
“Stripped
apart”:
Stripping
old chrome involved use of strong acids and salts, which can excessively
remove brazing material. We have seen frames virtually disassembled
or by over stripping!
The “hole”
story:
Fork blades,
seat stays and top tubes which often have small vent or worse no obvious
holes but invisible gaps in brazing, that can allow the charge solutions
to be “drawn” inside and trapped. We have seen frames
with this problem rust out within months. It is critical that all areas
in which solutions can enter have two holes of about 3/32”. Most
fork blades and seat stays have a single hole to allow exit of hot air
during brazing. Filling such holes is unreliable, because charged
plating solutions will penetrate gaps only microns in size. If
a seal is achieved, it can be opened during polishing. If a leak
is detected after plating, two holes must then be drilled through the
new plating. For this reason we often drill a second set of holes
in fork blades and seat stays prior to plating. Certainly beats rust
holes!
“Chrome
shadows”:
Chrome plating
does not cover all immersed parts equally. The electric field
is weak in enclosed areas (like the seat stay and chain stay joints)
and strong at sharp edges (outer lug edges). Thus plating can be too
thin in the weak field areas and poorly prepared sharp edges can have
chrome buildup. This can all require a lot of polishing, manipulation
of electrodes and finesse for a good job. Many older frames, for
example, show surface rust at the thinly plated chainstay and seatstay
areas. Placement of additional anodes and other techniques are
required to “throw” plating in difficult areas, something
few shops will attempt.
A real
“drag”:
Platers must
be concerned about “dragging” solutions, that is, carrying
them from one tank into the next. A few parts per million of such
contamination can both render a 500 gallon tank to useless toxic waste
and in the case of a rinse tank, cause toxins to discharge to the sewer
system and cost potentially mean a large fine or closure by regulators.
“Polished
off”:
Re-plated
frames are usually rust pitted and require careful and thorough polishing.
Lugs and braze-ons are mild steel, tubing is much harder, many platers
lack the tools and experience to polish thoroughly without eroding the
edges of these parts. Improper polishing can even thin the
tubing walls or distort the frame alignment, compromising frame integrity.
“Less
is more”:
If one is
plating a frame which will be painted except for head lugs and dropouts
for example, there is no advantage to plating the entire frame.
It is easy to immerse the whole frame, but we minimize the plating on
the frame by suspending it only partially immersed. This reduces
unnecessary weight and increases paint adhesion. We have seen
platers attempt to accomplish this by masking which creates a terrible
ridge at the edge the mask that must be ground down prior to painting.
What were they thinking??
“Does
not count if is does not stick”:
For optimum
adhesion of the chrome to steel, tanks chemistry and electrical contacts
must be precisely maintained. I may be that adhesion acceptable
for many applications is not sufficient for bicycles, where chrome sees
severe abuse by quick releases. Quite often, when working with
other’s chrome, chrome will peel during the pre-paint blast or
worse, when we remove the masking after paint!
Why does chrome cost this much?
Many reasons:
Polishing for chrome plating is dirty, tedious and dangerous work .
Efficient polishing requires horsepower. Most platers use wheels
with 12 for 25 horse power motors, running at 1260 RPM. A mistake
that causes the buffing wheel to catch between the stays and seat tube
can result in severe injury. Then there
are the hazards
of exposure to strong acids, heavy metals, dusts and high voltage.
Platers earn hazardous duty pay! Meanwhile, most quality
plating shops have a clientele of motorheads who throw thousands of
dollars at the chrome on their projects, which rarely present the hazards
of our bike frames! Lastly due to the hazardous nature of plating it
is very expensive and difficult to get the permits to build and operate
one.
Do you triple plate?
We frequently
get requests for “triple plating” i.e.; copper, then nickel
then chrome. For many years this was the hot technique, especially
for hot rodders and bikers. The downside is that the copper adds
unnecessary weight and thickness, in fact, unless care is taken, threaded
and press fit surfaces will be compromised. New nickel formulations
don’t require copper to adhere to steel and give excellent results.
Copper as a base coat does still have a use however; it can be applied
with considerable thickness and it penetrates well in to recesses.
This provides a thick, soft, base layer which can help fill pitting.
Still unless there is a need, we do not use copper.
What is Hard Chrome Plating?
Hard chromium
plating is just chrome plating, but it is applied as a fairly heavy
coating (usually measured in thousandths of an inch) for wear resistance,
lubricity, oil retention, and other 'wear' purposes. Some examples would
be hydraulic cylinder rods, rollers, piston rings, mold surfaces, thread
guides, etc. There are variations even within hard chrome plating, with
some of the coatings optimized to be especially porous for oil retention,
etc. It is called hard chromium because it is thick enough that
when a hardness measurement is performed the chrome hardness can actually
be measured. It is not really shiny or decorative.
The plating
we do is “decorative” chrome plating and always involves
plating nickel before plating the chrome. The chrome plating in decorative
chrome plating is exceptionally thin, measured in millionths of an inch
rather than in thousandths. It is still a very hard surface, but simple
'anvil' type hardness measurements don't detect the hardness because
the anvil just punches through such a thin coating.
When you
look at a decorative chromium plated surface, most of what you are seeing
is actually the nickel. The chrome adds a bluish cast (filtering the

Jim's Velo Rendezvous Symposium Presentation
Should this bicycle be repainted? A daily question
here. It's one I try not to preach about, I respect a range of
opinion on this subject and try to offer feedback to assist in coming
to a satisfying decision. I found my notes for the Velo Rendezvous
presentation. I think they cover this subject about the best I
have done to date, so here they are:
Should this bicycle be repainted? It’s a complex question,
with many answers and few absolutes.
It is instructive to look to the larger, more mature and more moneyed
field of antique furniture for insight: Take this quote from “Art
and Antique magazine”:
“Over the last few years, the media (and TV in particular) have
provided a near constant barrage of antique and appraisal programming
that has heightened our antique awareness. They also have
created an induced neurosis, which could be characterized as “Don’t
touch it!” The experts on such programs frequently
claim that a given piece would have been a very valuable item if only
the owner had not repaired, or stripped, or refinished the piece.
While this may be true for many legitimate antiques, such as an original
Louis XVI chair, for example, it is not necessarily true for all “old
furniture.” This “don’t touch it “
attitude has created mass confusion and doubt about older furniture,
in general.”
It seems to me that the refinishing work on the devalued pieces featured
on TV is often poorly done. Had it been done well it might not
have had such a negative effect or might have not been detected at all.
In the antiques furniture field, there are long established schools
and licensing for appraisers. Thousands of individual pieces trade
at auction for 10’s and sometimes hundreds of thousands of dollars.
With our vintage lightweights, we have few resources by comparison,
a good percentage of them are in this room. Likewise, the market
for the objects of our desire is tiny and their prices are modest.
I propose, that given the relatively low valuation most of our bikes
hold, we should use even the best of them occasionally. Putting
them where they will be seen and appreciated is better than storing
them ‘til we die. If that means that more of these bikes
will need refinishing than if they were treated like a Louis XIV chair.
So be it.
Looking to another, large and mature field, a recent survey of classic
car shows suggests that 95% of the cars in attendance had been refinished.
There is no great fear of loss of original finishes and scraping rust
off chrome and waxing over the pits is not considered proper stewardship
of a classic.
When I am asked for advice on whether to repaint a bicycle, I consider
three key elements, the bicycle, it’s condition and the intentions
of it’s owner. I then try to help by providing options and
information on the possibilities and ramifications.
I’ve worked this out on paper as a self quiz:
First, with your bike in mind, consider its category:
Bicycle categories:
1. Rare, with provenance and very high value
2. Rare & interesting with high value
3. Popular classic with good value
4. Common with moderate value
5. Unpopular or low value
Then consider its condition:
Condition categories are:
1. Near perfect original
2. Slightly blemished
3. Poor condition
4. Unsatisfactory refinish
5. Significant rust or damage
Now consider your intention for this bike.
Owner’s intention:
1. Preservation
2. Resale
3. Vintage show bike or museum display
4. Use with display or resale a possibility
5. Extend useful life of frame, authenticity not a
concern
6. Upgrade or customize
Take the numbers of each choice and add them up. Scores will fall
from 3 to 16. Find your number in the options below for a recommended
option and cost range:
1. Preservation services 3 to 5
$50 to $150
2. Touch-up 5 to 8
$75 to $350
3. Refinish 7 to 16
$160 to $950
4. Custom. 11 to 16
$120 & up
Sometimes “preservation” is only the way to go.
For example: A fine and rare bike that has been maintained in
close to original, as-made condition; and has a documented, even interesting
history, and; there is intent to sell it for its collector value, would
score just 4; certainly a case where ‘don’t touch’
is the rule. Greg LeMond’s 1989 Tour de France winning time
trial bike would fall into this category, as would other important race
winners, pioneer tourist Velocio’s bikes, the Schwinn family triple
and others. Very old bikes with heavy patina also usually fall
into this category.
For these bikes, we recommend very careful, even limited cleaning and
proper storage and display. Sometimes, on older bikes, we see
finishes that are severely oxidized and so have lost their gloss and
much of their color. Decals and pinstripes are reduced to a very
fragile oxidized layer easily damaged by cleaning or polishing.
In these cases, we preserve them by cleaning with extreme caution and
applying a thin coat of clear to protect and bring out the original
colors. This is still preservation.
The most frequently overlooked option is that of “touch-up.”
While this can be performed with a scraping tool, carefully matched
colors and a paintbrush, the results are usually conspicuous.
Using airbrushes, blending techniques and partial decal and stripe replacement
as required, it is possible to touch up localized damage, rust, dents
or frame repair, invisibly, while preserving an otherwise original finish.
We have performed both brush and invisible touch-ups including dent
repair, cracks and braze-on replacement leaving the repair undetectable.
It helps that CyclArt has built and maintained a complete color mixing
system and decal production capability in house.
Sometimes, touch-ups, which start at $75 are far more cost effective
than a complete refinish, but many factors affect their difficulty.
Color matching, multi-layer colors like candies and pearls, airbrush
effects, number of areas affected, pinstripes, decals, chrome
and damage can all be overcome, but can push the price to exceed that
of a refinish. I have been very proud of our ability to make an
invisible repair to complex finishes. I recall a lace-painted
Tommasini and a stained and crazed Claud Butler that we were able to
touch-up invisibly and can still be called and original finish.
If the situation calls for a refinish, care in documentation and execution
is paramount ~ even for Paramounts! CyclArt takes "before" and
“after” photos as part of restoration projects. We have
the ability to replicate virtually any color, pinstripe, airbrush, chrome,
any technique originally used. Given the economies of production,
one often invests several times as much labor restoring a bike as was
put into building it in the first place. But this certainly parallels
other industries, such as antique furniture or vintage cars.
At CyclArt, we have always discouraged restoration as investment.
On the other hand, there is great satisfaction in returning a sad, battered
and rusting old campaigner to "better than new" former glory.
This year's super-bike is next year's old news and carries a guarantee
of immediate depreciation. On the other hand, vintage bikes are
appreciating in value, and become increasingly interesting with age.
Then, of course, there's that special satisfaction in dropping the guy
on the high tech bike.
Once a decision to restore is made there are still questions for those
who are very concerned about authenticity; Do I compromise accuracy
when I use a toner that won't fade?? What if I fill a dent caused
by the builder? How about correcting alignment? Some old
finishes exhibit obvious flaws, should they be recreated? What
if it looks too good? Smoother, richer, more even color, crisper
masking, straighter stripes, clearcoated decals, better chrome polish,
brazing gaps and file marks filled... Are these things objectionable?
Is it wrong to recreate the frame as beautifully as possible?
Would the builder have done so if he had the means?
Unless requested otherwise, we repair damage and rust pits, perhaps
improve lug edge shape slightly and fill pinholes and gaps. We
normally exceed original finish standards, partly out of improved material
and process, mostly out of pride. It is extremely
rare, but if the client is concerned with “over restoration" and
we'll take special care to match the "character" of the original with
all it’s flaws.
The fact that we can do very accurate refinishes brings up another question,
that of weather or not to apply our decal to identify the bike as a
refinish. I've always been uncomfortable with not applying the
small CyclArt decal on accurate restorations. Although the client's
intent may not be to deceive, it seems probable that at some time in
the future the bike will likely be misrepresented as "original".
One of the greatest challenges, and one the more interesting aspects
of all this, is that mystical substance “patina”.
One man’s dirt and damage is another’s character and mark
of authenticity. There are no rules or formulas here. It is “patina”
when it makes the bike look old. It’s not, when the bike
looks damaged, abused or neglected. I consider repairing damage
and touching up a heavily patina-ed finish undetectably may be our greatest
accomplishment. We have even performed complete refinishes were
the paintwork was matched to the level of patina on the components.
The final option I’ll bring up, may be the most controversial
among this crowd. But here goes: If you intend to keep a bike
indefinitely; if it is not exceptionally rare or valuable and if visions
of a custom bike keep fogging your Oakleys... consider that an ordinary
bike can become an exotic. Bicycle "hot rods", can be just as
exciting as their gas-guzzling brethren. As with the auto hot
rods, there is a certain charm to a tasteful mix of old style, new performance
and perhaps some custom paint. Favorite old frames, with upgraded
paint and adapted to contemporary components can be the best of both
worlds for some. Many clients come to me with old favorites that
they want to upgrade. Typically they seek longer cranks, smaller
chain rings, or wider gear range. After all, riders age too and
sometimes they need a little help to keep up with their riding partners.
We repaint many brand new bikes too. As much as I love the pure classics,
I'll admit, that some of my best moments at CyclArt have been in helping
a rider define and realize his dream bike. Sometimes, the client
has worked out the design and we execute it carefully to the letter,
other times, we brainstorm with the client to extract his sleeping dream
bike. When they're "right", such bikes can be very seductive!
The choice it yours, we're here to serve.
