THT Wheels Auto Show Makes a Roaring Start
THT Online Kathmandu,
No less than 15 four wheelers were booked on the first day of the
three day-long THT Wheels Auto Show, which kicked off at Birendra
International Convention Centre (BICC), Kathmandu on Friday,
according to preliminary estimates.
According to the [organizers] of the event, The Himalayan Times, 10
two-wheelers were also booked, which clearly reflects the immense
popularity and usefulness of the show, both for buyers and
sellers.
[...]
At the show, major auto industry players are displaying their
quality products and services under one roof for the benefit of
customers at a time when the great Nepali festivals Dashain and
Tihar are approaching.
One of the biggest draws of the event has been the electric
vehicle 'Reva' on display. Although, most visitors flocked to
take a look at Reva, they expressed dismay at the whopping Rs
800,000 tax on this environment-friendly vehicle which is more
than the price of Rs 700,000 of the vehicle itself.
Go-karting, food stalls and display of vintage cars lent a
fun-filled and colourful atmosphere to the event. The event is
coinciding with the 6th ANBUG Himalayan VW Beetle Rally,
scheduled for 16th September on Saturday.
The organisers of the show informed that the auto show is
showcasing many more new arrivals in the automobile sector in
Nepal in the category of four wheelers, two wheelers, accessories
and spares which will be offered at discounted rates.
Besides auto sector players, financial companies, insurance
companies, authorised vehicle dealers and equipment sellers are
also adding value to the exhibition, say the organisers.
Those who want to book cars during the exhibition are entitled to
get additional discounts and offers from different companies.
Standard Chartered Bank, Everest Insurance Company, Rastriya
Banijya Bank and other companies are giving special rates on
their services.
Similarly, special discount has been arranged for buyers of Bajaj
motorcycles. Raju Chhetri, general manager at Hansraj Hulaschand
and company said that the company has introduced 'spot financing
and spot exchange offer' to facilitate consumers alongwith other
additional benefits.
Similarly, Pranesh J Pradhan, one of the exhibitors who sells
Hyundai cars at the THT Auto Show says that an equivalent of Rs
15,000 worth of equipment and parts are being given to customers
free of charge who purchase a Hyundai car at the exhibition.
Pradhan also informed that upto 90 per cent financing facility is
available for Hyundai cars.
Entry to the show has been fixed at Rs 20 per person. On the sale
of tickets, every day a lucky winner can get an IFB washing
machine worth Rs 49,900 and a bumper prize of Bajaj Discover DTSi
bike at the end of the event.

Plenty of fury, a lot less sound
ELECTRIC BIKE LEAVES NOISE, FUMES IN DUST FOR OFF-ROADERS
By Matt Nauman Mercury News
Karen T. Borchers / Mercury News
Neal Saiki rides one of his Electricross bikes. One or two of
them will race against gas-powered bikes this weekend.
Electricross basics
He designed a human-powered helicopter in college, then worked at
NASA and then helped develop a high-altitude airplane (to be used
to confirm global warming and as a spy plane) for another
employer. Next, he became a famous mountain-bike designer, and
now he's making electric motorcycles.
The common themes? Innovation. The use of lightweight,
high-strength materials. And, of course, Saiki, 40, whose
Electricross opened in a small Scotts Valley shopping center in
July.
This weekend, one or two of his bikes will compete against
gasoline-powered motorcycles in a race near Sacramento.
He thinks it'll be a milestone moment. He's convinced of the
inevitability of electric transportation, and knows that
dirt-bike riders face growing pressure from people who don't like
the pollution (noise and smoke) they produce.
His electric motorcycle, the Drift, is hand-built. Saiki designed
it and uses shops in Soquel, San Jose and Santa Cruz to make the
parts. He starts with aircraft-grade aluminum and does final
assembly in his 1,140-square-foot workshop in back of the store's
display area.
Two models exist. The all-terrain version sells for $5,500. The
motocross-ready one, complete with shocks from Fox Racing, now
based in Watsonville, is $6,300.
He's talked to potential investors, and knows he'll need their
help to turn his small enterprise into a successful business.
But, he said, he wants to do more than make money.
Powerful magnets
``Electric vehicles have a horrible image problem -- that they're
slow, they're not powerful and they're not fun,'' he said. ``I'm
really trying to change that image.''
Many young people love off-road bikes, especially those built for
motocross activities. Events such as the X Games and the recent
Dew Action Sports Tour in San Jose have become popular. His store
is right next to Scotts Valley's middle school, and every other
kid he sees is wearing a Fox Racing T-shirt, Saiki said.
``The kids these days love to see all the motorcycles jumping,
doing flips,'' he said.
That's why the www. electricross.com Web site has videos that
show the Drift flying through the air, and taking hard turns. He
said it shows the bike is rugged, capable and comparable to
gasoline models.
It weighs 140 pounds, including the 60-pound battery. A motocross
bike such as the Honda CRF250R weighs 215 pounds and sells for
$6,199. Similar models from Kawasaki and Yamaha are just a bit
cheaper.
``It weighs a lot more than a mountain bike, but weighs about
half the weight of a motorcycle,'' said Saiki. To preserve that
combination of lightness and strength he had to design most of
the parts, including the frame, wheel, rim and spokes, rather
than buy off-the-shelf parts.
The secret is in the Drift's electric motor, made in China by
Briggs and Stratton. It's lined with strong, rare-earth neodymium
magnets. They're strong and efficient, Saiki said.
``If you set one on a table, you almost have to use a screwdriver
to pry it off a table,'' he said.
They allow the bike to go about 20 miles on a charge using about
a dime's worth of electricity, Saiki said. Top speed is 45 to 50
mph.
The bike comes with a choice of three powerpacks, ranging from
one that costs $210 to $2,200 for one with a lithium-ion battery.
``It's half the weight. It doubles the run time, and it's very
expensive,'' Saiki said.
A bicycle, a helicopter
Two charging units also are offered -- one takes 30 minutes, the
other takes two hours. But, Saiki said, the bike is designed for
a fast change of batteries so riders can ride one and charge
another at the same time.
As a student at California Polytechnic State University-San Luis
Obispo in 1989, Saiki headed a group that created the Da Vinci
IV, a 97-pound helicopter that took a short ride into history.
With a world-class bicyclist pedaling, it left the ground for a
few seconds.
That fascination with transportation -- he has a master's degree
in aeronautical engineering -- eventually led him to design work
as a consultant for championship mountain-bike teams. And
advances in electric-motor technology convinced him of the
potential for a powerful, efficient electric motorcycle.
One or two of Electricross' bikes will participate in the
Bushwackers MC's Furnace Hare Scramble on Saturday and Sunday at
the Prairie City State Vehicular Recreation Area east of
Sacramento. This will be the first time an electric vehicle
participates in an event sanctioned by the American Motorcyclist
Association, said Dennie Conrad, a vice president of the
Bushwackers MC, a group of motorcycling families.
Dal Smilie, chairman of the 250,000-member AMA, characterizes the
demonstration of an electric off-road motorcycle as a ``pretty
radical departure'' for the AMA.
``It is pretty exciting to see alternatives to traditional
fossil-fuel vehicles being tested, examined and used,'' Smilie
said. Innovations in racing often eventually show up in street
vehicles, he noted.
``All this will help engineers perfect alternative methods of
propulsion which will make motorcycles more efficient and more
useful than they already are,'' said Smilie, a government lawyer
who lives in Montana.
Although intended for off-road use, the Drift comes with a toggle
switch that reduces the power and allows it to be driven on roads
as an electric bicycle.
Tony Watson, and his 10-year-old son, Andrew, are happy to be
among the first owners of a Drift from Electricross.
Watson, who lives in the woods in Scotts Valley, noticed that new
neighbors can be more sensitive to noise. ``Before, the kids
could go putt-putting down the street and nobody made a fuss.
People moved in, and that changed.''
He saw a newspaper advertisement for Electricross, and went to
check it out. Impressed with the quality and engineering of
Saiki's bike, he bought one.
It's for Andrew -- he has five dirt bikes in the garage. But when
280-pound Watson brought it home in his truck, he was tempted to
try it out.
``Two and a half hours later, I finally retired it to the garage
for the night,'' said Watson, who sells recreational vehicles.
``It's the biggest spectacle around.''
So far, he said, the bike has held up well to off-road use, the
kind of tough-terrain activity that shreds a back tire. In fact,
Watson said, he's thinking of getting another one.
Saiki admits that ``a lot of Americans have a real love affair
with the noisy motorcycle.'' Still, he said, ``even if you love
it, your neighbor doesn't love it.''

HIGH-TECH WIZARDRY TRICKS OUT 1964 VW
By Matt Nauman Mercury News
The hippie van has gone high-tech. Volkswagen's Silicon Valley
research lab has used the iconic symbol of the '60s as a platform
to display new technologies such as lithium-polymer batteries,
surfboards lined with solar panels and even an electronic bumper
sticker.
Called Chameleon by Vickie Chiang and the 20 other engineers who
worked on it at Volkswagen's Electronics Research Laboratory in
Palo Alto, the concept VW bus makes its public debut next weekend
at the AltWheels Alternative Transportation Festival in Boston.
``It says a lot about how we want to maintain the spirit of VW,
which has a unique, fun-to-drive image, especially in the U.S.,''
said Chiang, the engineer in charge of the project.
At the festival in Boston, the Chameleon will be displayed with
all sorts of vehicles that use electricity, solar power,
hydrogen, biodiesel and other sources of energy.
The year-old project started with a 1964 Volkswagen 21-Window
Microbus Deluxe, a vehicle once used as a surfer van or family
camper and now considered a ``highly sought-after'' classic by
collectors, said Gary LaVere, who restored the vehicle for VW.
>From a distance, the Chameleon looks like a typical VW bus,
complete with round headlights, maroon-and-white paint job,
Safari-style front windows that open outward and upward, canvas
roof and even two long-boards stored on wooden racks.
``We decided the theme of the bus should be hidden technologies,
because you didn't want the technologies to overshadow the look
of the bus,'' said Chiang, a 24-year-old Stanford University
graduate.
A closer look reveals that this indeed is a modern machine. It's
crammed full of high-tech items.
No gas tank to fill
Beneath the gas-tank door, there's a palm-vein recognition sensor
from Fujitsu. More exact than a fingerprint reader, Chiang said,
it is used to unlock the doors -- or to lock them if the vein
print isn't recognized. Since the Chameleon is an electric
vehicle, the gas tank has been removed.
Where the horn used to be, there's now a touchpad sensor from
Synaptics. With it, a user can negotiate the vehicle's music,
navigation and parking-assistance systems.
Behind the front seats is a 60-inch projection screen from Sony.
Using home-theater technology, the screen's polymers absorb and
reject certain wavelengths of light to produce a brighter,
higher-contrast image. ``It's very good for situations where
there's a lot of ambient light,'' Chiang said.
In the middle of the van's rear bumper is an electronic device
from SiPix that allows personalized bumper-sticker messages. It
looks like glass, but it's plastic. VW engineers have typed in
about a dozen greetings, including ``I love my bus'' and a peace
symbol, ``Hi Mom!'' or ``Yes, I just passed you.''
Other neat bits include light-emitting diode front and rear
lights from Osram Sylvania, a digital voice-enhancement system
from Applied Signal Processing, and solar cells applied to
surfboards from Hybrid Technologies.
The project was first headed by Philippe Alessandrini, who has
since left the VW lab to study at Harvard's Business School.
Alessandrini found the van in fall 2005 on eBay, Chiang said.
The van was shipped to Hybrid Technologies in Mooresville, N.C.,
where its lithium-polymer batteries were installed. The 10
30-volt batteries, under the van's floor, are enough to allow
about 100 miles of driving, Chiang said. Charging, which takes
about six hours, is done with a cord that attaches to where the
van's tailpipe used to be.
Like `Pimp My Ride'
Once it was electrified, the van went to LaVere's VW Restorations
in Concord. It was taken apart, restored and modified where
needed, painted and reassembled. A job that would usually take
six months was done in six weeks.
``It was `Pimp My Ride' fashion, which we'd never done before,''
LaVere said.
Then, California Concepts hooked up all the electronic bits, and
finally the lab's engineers did a bit of testing and
troubleshooting.
In May, it was shipped to Germany for display at a twice-yearly
internal Volkswagen Group technology show.
Volkswagen's Silicon Valley research lab opened in Sunnyvale in
1998, and moved to its current facility near the Department of
Veterans Affairs hospital and Gunn High School in Palo Alto in
2002.
The lab's mission is to scout for suitable technologies from Bay
Area companies and universities, and to create its own projects
that might end up in future VW, Audi, Bentley and Lamborghini
models.
It gained fame last year when Stanley, the robotic sport utility
vehicle it created with Stanford University, won a $2 million
prize for winning a driverless race in the desert.
The lab won't say how much the Chameleon is worth. A classic VW
bus without the high-tech treatment sold for $45,000 last month
in a Monterey auction.
In a stroke of good fortune, the van came with its own California
vanity plate: 64 DLX.
``We thought the Deluxe Microbus was great because it has such an
emotional feel to it,'' said Chiang. ``It has such a nostalgic
following, and it does really symbolize California and the U.S.,
which is something we like to bring back to Germany every so
often.''

And Rich -
If you didn't tear out the power steering yet, consider coupling the pump
directly to a PM DC motor that runs off the pack. If you size things right, it
will use a couple amps straight ahead and maybe 6 amps turning (at a pack
voltage of 144 volts). And you can shut it off when you want. You don't have to
run the pump fast.
Thing is, power steering, and nice accelerator peddle action defines your
everyday experience in the vehicle. If you want to rough it, just turn off the
switch and experience manual steering.
It will be like Dr. Jeckle and Mr. Hyde.

That's the beauty of it, it does SOUND perfectly valid, so did Ford's excuse
and it took list members to point out to the reporter that he had been duped.
I'm not saying that their excuse has absolutely no merit, I'm just saying that
given the tract record of the major's when it comes to their EV programs, you
can't trust a thing they say about *anything*. Ask for proof about *everything*
I'm hoping someone here has a connection to the council in Pasadena so they can
ask for proof of this bogeyman at customs. I'd bet me left ... something or
other, that the customs agent has no name and is unreachable, and left no
documentation with Nissan regarding US Customs position on this.

Subject: Re: Bearing replacement tips?
Hey Eric
To answer your question, yes the weight of the 2' prybars is most the
time enough to move the bearing once heated. You can use a little force
if this doesn't happen though. If by myself I'll use my elbow on one
prybar while my hand pushes the second one. I have the torch in the other
hand and focus on the inner race with a hot, focused flame. This should
only take a minute to do. If it don't work let it cool and try again.
Just don't keep on it if it doesn't do it. As far as glooves go I'd opt
for anything you could use as leverage vs trying to grab it with a glooved
hand which would offer no leverage. Besides This needs to get really hot
so unless you got really good glooves you'll be playing hot potato big
time.
PS: This lets out some good smoke just so you know.
If you think this is bad try removing that plastic fan without breaking
it, LMAO!
Hope this helps

As a matter of fact, my oxy/acet rig is about 4 feet from the motor =)
I have a fine-point nozzle for precise heating.
The fan itself is plastic, but I don't see any way that the pry bars
_wouldn't_ put pressure on the fan, unless you mean that the weight of
the pry bars alone is okay on the fan.
As an alternative, can I heat up the inner race, and simply pull it off
with my (leather welding glove adorned) hand?

As far a user is concerned, it's a value (typically >0.1F and above),
but design wise supercaps usually have porous material (like carbon)
electroplated with thin layer of conductive film over insulator layer.
The other electrode is
electrolyte touching all that film in its entire area, thus so giant
capacitance. A 1 cubic foot chunk of carbon has many square *miles*
surface area if you *unwrap* it all in a flat sheet equivalent.

Advertising. Salesmen will stick a "super-" or "ultra-" prefix in front
of anything to make it sell better. :-)
There are many different capacitor technologies, of course. But most of
them, over time, have gotten some more meaningful adjectives to describe
them -- paper, ceramic, plastic film, or electrolytic; depending on what
material is used for the insulating dielectric between the plates. There
are lots of variations in what metals are used for the two plates, too;
but since they don't directly affect functionality, they aren't very
helpful.
All supercapacitors and ultracapacitors are really electrolytic
capacitors. They use a liquid electrolyte between the plates. The plates
are typical aluminum or carbon, both of which can be processed to
provide extremely large surface areas.

You just need to get it on and in the right spot quickly.
BTW, for removal: I did not have a torch when I needed to
get something off that could be destroyed, so I took a metal
saw and cut it (though here that may be hard with the fan
and rotor behind it)
NOTE that I did not cut it until I was through - Jim H
showed some pictures last year of a axle with angle-grinder
markings. I only cut it far enough to weaken it in one spot and
give me a place to put a chisel or prybar and break the
remaining material, so it will come off easily and
without damaging the axle.

I had to do this once with an old DC generator for my Edsel. I heated the
bearing on an electric stove burner, and stored the armature in the freezer
over night.

What would it take to get John Wayland or Jim Husted to go take a look at
these? there's still 3 days left and bidding is still
low. I wouldn't bid my self but if they were in salvagable shape for cheap I'd
buy one from the winner, if one of these guys says
they're in decent shape, or even usable.

I left the pump plumbed in just in case I wanted to attach it to the tail shaft
on the Mitsu MightyMax. However it turns fine
without it. Its harder when going slow or stopped, but all manual steering is
like that. It actually turns better than the manual
steering on my old '64 and '65 Chevy pickups. So at some point the dead weight
of the pump will come out and I'll loop the in and
out hoses from the steering unit, as was mentioned earlier in this thread.

Hey Eric
To answer your question, yes the weight of the 2' prybars is most the time enough to move the bearing once heated. You can use a little force if this doesn't happen though. If by myself I'll use my elbow on one prybar while my hand pushes the second one. I have the torch in the other hand and focus on the inner race with a hot, focused flame. This should only take a minute to do. If it don't work let it cool and try again. Just don't keep on it if it doesn't do it. As far as glooves go I'd opt for anything you could use as leverage vs trying to grab it with a glooved hand which would offer no leverage. Besides This needs to get really hot so unless you got really good glooves you'll be playing hot potato big time.
PS: This lets out some good smoke just so you know.
If you think this is bad try removing that plastic fan without breaking it,
LMAO!
Okay, I just tried to get the bearing off. I removed the grease seal
and tried to remove some of the grease with a paper towel. Hit it with
the torch, and *poof*. Now, there's _no_ grease on one side of the
bearing because it all smoked.
In any case, it didn't work.
I think I did three things wrong:
1) I let the shaft get too hot. I figure I should aim to heat the
_bearings_, and avoid the shaft at all costs. Incidental heat blasted
sideways should heat the inner race.
2) I didn't get the race hot enough. Or maybe I did. I don't know. It
was hot enough on the outer race to make a wet finger sizzle. The shaft
was too hot to touch, but not as hot.
3) I need to get another pry-bar. Or at least use the one I have
instead of a big screwdriver.
In the interim, I put Kroil on the interface between the shaft and the
inner race. We shall see if it's looser.

Where is a good source for some pulleys and belts that can handle the

Or maybe I should say, what is a good online source for them with a good

I have upgraded my drive pack from the original 96 volts to 108
volts. While I like the extra power, it has made the original 'state-
of-charge' meter unusable. I would like to keep the outward
appearance of the car as originally built. This includes the
original meters. Is there any way that I can make the original
'state-of-charge' meter useful again? That is, what do I need to do
to restore the meter to working as well as it originally did?
By the way just how accurate would that be?
