Tah dah! I deliberately saved the "visor down" shot till the end so
I'd have something different to show you. Cheap theatrics, huh? I didn't
think the electroplating would be a big enough change, since it's just
a different type of finish. The figure costuming "look" was apparent even
before the finish, but just like a model or sculpture, finishing steps
like painting or electroplating satisfies curiosity and cements the look.
Electroplating differs from painting in one significant way: It's a
friggin' bitch that takes forever and wears you out. So a project
like this can seem to be almost done in paint-mentality, but weeks away
from completion in electroplating-mentality. Some of that is due to the
plating time-- I'm nervous about letting it run unattended, so I try to
schedule those long runs while I'm around to check on it periodically.
That doesn't leave too many windows of opportunity when you've got a day
job. The other part is the endless, time-consuming grinding and polishing.
Spending an hour or two an evening continously hunched over your Dremel
wearing a filter mask and goggles to work on a single piece is hardly
my idea of fun. It's grungy work that gives you back problems. You definitely
have to approach this with quite a bit more patience to offset that yearning
for quick gratification. As shown, the figure is quite a ways from completion--
held together by chewing gum and rubber bands, so to speak. It's gonna
take a while to finish, but most of the remaining progress will be pretty
unremarkable. I mean, do you really care to see that the back piece is
polished? That makes it a lousy prospect for an ongoing web page article.
I alluded to some of the setbacks in my recent "Remarks" entry. Actually,
every step of the electroplating process has been frustrating. It's understood
that the process isn't as quick as painting, but there can be quite a
few learning experience gotchas which just make it take so much
longer. However, my first unpleasant experience was of my own doing, the
result of my own stupidity.

In order to electroform, you've got to connect wire to the piece you're
plating. This brings electricity to the conductive paint, which attracts
the metal in the solution. At the start of this process, I didn't know
if I was going to do the final plating in nickel or gold (I believe that
I'll leave it in copper, since it's more of a workin' woman's material),
so I left the wire connected to the first piece (the shield) and proceeded
to the initial grinding and polishing phase. This was a big mistake. I
was about three-quarters of the way through when I inadvertently grazed
the wire with my Dremel (running a really high speed); it managed to snag
the wire and wrap it, flinging the shield around and around as I fumbled
for the Dremel kill switch. All in the blink of an eye. By the time I
found the switch, it was too late. The shield had already been flung somewhere,
and the tail end of the wire had flagellated my leg several times. Ouch.
Unfortunately, the shield had been flung on edge, hit something hard and
now had a major dent in it. We're not talking about just the plating being
damaged/missing chunks, but the thermoformed shield underneath was dented
too. Knowing that plating isn't removed quite as simply as paint is, redoing
it from the start was out of the question: I decided to patch the damage
and hope that additional plating would cover the damage. It worked-- sort
of. The additional plating at least covered the bare spots, but the plating
is much thinner there and warped. And now the shield weighs a ton from
all the additional plating. I'd planned on backing the shield with wood
(like the real thing), but I didn't plan on the thing being quite so heavy.
Another aggravation in the quest for perfection is that the plating
tends to be of uneven thickness, and you can't tell where by visual inspection.
This means that if you're grinding away the surface imperfections, there's
always a chance that you're going to grind through to the substrate. When
this happens, you're screwed. It means patching and another long dunk
in the bath to build up the layer, then bunches of grinding to blend the
uneven levels out. And if you grind through that top layer, you'll hit
the middle paint layer which separates the two plating sessions, and you'll
then be staring at edge intersection of two plating layers, which can't
be blended. Then there are the tiny spots which, possibly caused by the
contamination of some non-conductive impurity, don't plate. You might
not notice them at first, but as you grind, you find an occasional tiny
pit which might go all the way down to the substrate. So much for perfection...
I've noticed that the plating proceeds gradually in patches, radiating
out from where the wires are connected. This still occurs, despite having
changed to brush painting which presumably leaves a thicker and more conductive
paint coating. It means that the current adjustment is considerably more
finicky. At the beginning, the highly conductive surface area is very
small (the wires), so a current setting for the entire surface area will
cause a nasty crusty buildup of loose granular plating where the piece
has good conduction. As the plating grows on the piece, the good conductive
surface area grows as well, so the surface area amperage needs to be adjusted.
If you don't build up the full surface conductive area gradually, there
will be huge variations in thickness and granularity as the plating builds
up more quickly in the plated areas (with good conduction). I'm trying
to figure out the patterns to make this more painless and predictable--
I have the feeling that this is made more difficult by changes in the
supplies I'm using. The chemical bath might be getting polluted (although
I filter it), and the conductive paint might be getting less conductive.
I'll probably buy some more conductive paint, and might splurge on the
more expensive silver variety.
In the area of design, there were a few surprises which really shouldn't
have been. I discovered (duh) that plating is not nearly as flexible as
sheet plastic, or even a metal sheet. Therefore, the clamp-on design of
the fitted forearm and shin armor were totally impractical. This is one
area where it works in real life because our skin and muscles are flexible...
but doll flesh isn't. So those pieces were trimmed to make them practical,
and it remains to be seen whether they'll end up as two piece assemblies.
That wasn't part of the original design. Likewise, the lower plate of
the skirt was designed to be a separate piece, but after plating, I cracked
it through the center while flexing it slightly during the polishing process.
(So the companion back piece was glued to the back armor before
plating.) Fortunately, the two-piece helmet design did work, although
the rough interior plating makes the fairly tight-fitted helmet harder
to place on and remove. (FYI-The cheekpiece relief decorations are owls,
but they're hard enough to discern even in person.)
|
The biggest question going into this experiment was how the relief detail
would stand up. Even though I put a lot of detail into the sculpting,
I had low expectations for how much would survive the plating. I wasn't
really surprised by the results either. Generally, it held up at a level
which seems appropriate for this type of process. In metal jewelry, you
don't expect to see razor sharp detail. That's because the polishing process
removes sharp edges. It's the nature of the process- polishing buffs are
big unfocused things compared to engraving and cutting bits. So it's not
unusual to see rough spots in tight areas where the buff couldn't go,
and generally the fine recessed detail is left alone-- filled by blackened
polishing rouge, much as a dark paint wash would do. Because of their
size, the buffs tend to obliterate some recessed detail as you're trying
to polish out adjoining areas-- the scaly texture on the snakes, for instance.
In some parts it's completely smooth, but in other areas you can see hints
of it.
Overall, there are tons of imperfections that bother me-- things like
pitting, uneven surface ripples, cracks, etc. They aren't readily visible
except under magnification because of the way this type of finish reflects
light. This would be totally unacceptable in a painted model, but here
it seems almost acceptable. Some of it can be fixed with a little more
polishing work (groan), some of it could be fixed at the risk of incurring
another dunk in the plating bath (groan)... so it's one of those things
that separates the perfectionists from normal folk.

05/20/01- If you don't get hung up on the imperfections, things move along pretty swiftly. Well, sort of... it's relative, you know? After the plating & polishing exercise, almost anything seems to move quickly.
Before plating, I'd done some preliminary thinking about how I'd do fasteners
& connectors. There are a number of ways you can do them, so not having something
specific in mind isn't reason to delay anything. I only planned out one area
during the design phase-- the shoulder hinges -- but they didn't work out quite
as well as I'd expected, so I'm even more of a firm believer in the "wing it"
method now. As I mentioned in the last project, I'm not a true believer in absolute
functional realism; I believe more in giving the surface impression of realism
on top of a more practical solution. An easy-to-illustrate example is belt buckles:
it's a simple mechanism, and not all that difficult to create in 1/6th scale,
but certainly a bitch for a fullsize human to thread with tweezers. It's acceptable
when there aren't a lot of 'em, but beyond that, it's an irritating thing to
deal with, particularly if you're in the process of creating costuming. A hook
is a far simpler mechanism to deal with, and if it can be hidden behind the
facade of a belt buckle, cool. Toy figures don't gain weight, so it's not like
the buckle's ever gonna need to be adjusted.
I
applied this thinking to the hinges which join the front & back sections
of armor together along the shoulders. This is supposed to be a hinge which
is closed with a removeable pin. Initially, I did consider using a dollhouse
hinge for this, but it was too large, so I made a hinge out of a pin & a
thin sheet brass. Even though it worked, I realized what a pain in the ass
it would be... so I sculpted a faux hinges on the front armor to overhang
the top of the back armor piece, and placed brass strips underneath, bent
in the shape of a hook. The back piece was cut with narrow slits for the
hook. (This is similar to the design I used for "Generic Fantasy Warrior",
but here the hook is on the topside, covered by the faux hinge.) This really
should have worked, except the hinge detail area plated horribly thick and
I didn't make the strip long enough to compensate for the edge plating accumulation.
At any rate, it doesn't matter much-- the armor is so snug fitted that it
doesn't rely on the top hinge to stay on (an advantage of the figure not
having soft flesh). The fit between the sections would actually be better
if I flattened or cut off the hook. I'll think some more about the armor's
side fasteners.
The forearm armor was another area where I thought I had a solution...
until I did the plating. Due to the stiffening of the piece from plating,
the squeeze-onto-forearm design was not practical and I didn't want to
rely on having to remove hands to do this. So the pieces were cut into
a front and back sections, plated, and rejoined with a thin piece of fitted
styrene. This gave them back the flexibility they lost through plating.
To "rationalize" the seam, I placed a faux hinge (scored wire) in the
channel between the pieces. Even though the hinge would imply some sort
of fasteners on the other ends, I'm not going to bother since that would
work against the easy-on/off design. Again, this is Fantasy... (?!)
I took the easy way out on the shin coverings-- I trimmed them so that
they had just enough grab to hold around the calf without excessively
stressing the plating when taking them off or putting them on. Maybe someday
I'll make the back plate for them? (Maybe not?) Because they wrap further
around than the forearm coverings did, they don't look as odd. Besides,
then I'd have to plate some more pieces (groan...)
In both areas, I softened the edges with rabbit fur. This was not done
as part of a plan, but as an extension of experiments to help conceal
the elbow articulation (or break it up a little-- I didn't want giant
puffballs at the elbows either). I wrestled with that one for a long time,
using leather, simulated mail & cloth. All those solutions created too
much bulk under the armor and looked unnatural. The rabbit fur looked
the most natural as edge trim on the armor, and didn't create the look
of a separate article which would need to be whole underneath the armor
and therefore add too much bulk. This solution also brought in a little
extra white color of a different texture, which is part of this figure's
color scheme. It's hard to explain the peculiar reasoning behind all this--
suffice to say, I'd rather have not put anything there, but the
ugly naked articulation hinges really bothered me and she needed some
arm flesh to remain uncovered, so sleeves weren't an option.

The crotch defenses/skirt was a fun addition. I redefined the initial overall
look a little bit, but adding the detail-- the copper buttons and ends-- really
had an immediate impact on the way the figure looked, and balanced out the detail
over the whole figure. Since I'd decided on a copper finish, I had to ponder
hard to come up with the buttons-- most decorative trim like this would be available
in brass, but plating such small things in copper, one at a time, wouldn't be
easy. Instead, I made the buttons by punching holes in copper sheet, backed
with a thick piece of leather. This compressed the cut edges, but left the center
dome-shaped... like little buttons.
And getting back to that ever-so-important question of scale weight...(I knew
you were curious) At this point, with everything except her yet-unmade sandals,
sword and dagger, she weighs a scale 167/203 lbs (avoirdupois/troy). Minus the
figure's weight, the armor comes in at 64/78 lbs. I carried a 30 lb bag of Miracle
Grow potting soil through a loooong checkout line last night, and I've gotta
say that the extra weight on top of my own 150 lbs felt heavier than a mere
extra 30 lbs. To carry around sixty-plus extra pounds long-term, I'm sure I'd
need to be outfitted with a pair of vintage-style ankles (and a back brace).
05/26/01-
Some accessories: (pic 1) The Roman sandals were adapted from a pattern
available at a website somewhere (do your research... in other words, it
was a long time ago and I don't have any idea what the link is). These were
eyeballed and simplified from the fuzzy authentic pattern: I didn't think
the thin, supple leather I used was going to stand up to a lot of cutting,
so the straps were made wider and fewer in number. One word of advice for
cutting leather: Use a virginal Exacto blade to avoid shredding it. Since
I wasn't concerned about historical accuracy, I also took the liberty of
gluing the straps together instead of lacing them. This avoided a lot of
frustration and eliminated the need to find some kind of lacing that looked
good at this scale.
(pic 2) The sword (first version) & speartip (and spear butt, not shown)
are somewhat faithful to Greek design, even though I made up the
details. I liked their designs and it was easier to copy them than try
to come up with my own. This might have been a more historically accurate
project if I had liked all aspects of the Greek or Roman outfit. On the
other hand, I do sacrifice historical accuracy for the limitations of
the figure anyway. The sword grip was deliberately made thicker because
the doll's hands weren't posed for gripping a thin object. (They're posed
to be multi-purpose: They look fairly good holding nothing, or holding
the spear and sword in a loose grip.) Likewise, I had to alter the design
of the shield grip since the historically correct hardware would have
to be oversized to accommodate the forearm armor, and be a hassle to fit.
(Besides, Amazons used crescent shields.) My feeling is that you should
try to get as close as you can, but don't sweat it-- this isn't a perfect
medium for realism after all.
The blades were fashioned from thick strip brass (spear butt from a
rod). It's a soft metal which gave me some hope of cutting the channels
and relief and polishing the suckers. (Still, it's not like working with
plastic.) I was eager to try something out: The brass was nickel plated
to look like steel without having to actually work with that difficult
metal. It wasn't a complete success, since the thin plating of nickel
didn't bond very well to the brass and seemed to wear away with handling.
(pic 3) I didn't like the sword blade's exaggerated curves anyway so
I reshaped it slightly and had to reconstruct the grip. I did the plating
again; this time, I tried to do the grip in copper and tried to keep the
blade from being plated by leaving an insulating gap between it and the
conductive paint (I didn't want a heavy buildup on the blade since it
fit snugly in the scabbard). Apparently, the current jumped the gap and
the blade was lightly plated. It was cool though-- the buildup was much
less than the horrible detail-obliterating mess on both the grip and the
scabbard. I salvaged what I could, because I wasn't about to go through
that again. This time, the nickel plating on the blade bonded well.
It's amazing how a simple thing like "making a sword" can turn into a lot of unexpected work. I guess I blocked the scabbard and belt out of my mind, or took them for granted. Nevertheless, those took a lot of extra thought before even getting started. I first tried to engrave the scabbard halves out of wood, but that was too bulky, so I formed them out of styrene.
(pic 4) The belt was an even bigger deal. I decided to do a fancier
Roman design with the plates and hinges but agonized over how I was going
to detail the plates. However it was done, it was important to get a fairly
uniform look on all the little plates. The were really too small for stamping--
besides, I've already overused the few metal stamps I have. That left
engraving, and with that, the decision about what pattern to do (over
and over) that would look reasonably consistent when done freehand. That
ruled out designs with a lot of straight lines, or things with too many
details. I finally chose the sun/flower pattern because the imperfections
and variations didn't call attention to themselves as much as non-parallel
or non-straight lines would. The "hinges" between the plates are the same
trick I used earlier with scored wire. I also made an operating buckle
with tine (despite whining about that sort of thing earlier-- there, I
was thinking more about the breast armor's side buckles). At this point
in the project, the belt's probably only going to go on once and stay
there, so I can live with that. The buckle was extra trouble to make since
I didn't have thick copper sheeting: I used a copper tube, slit it and
flattened it out. The decision to use copper instead of brass has brought
up a bunch of unexpected little problems like this.
I... uhhhh... changed my mind about the easy-to-make dagger, so that's
about it for this project (for the time being). Some R&R and then it's
time to start thinking about the next one, I suppose...
