Hello Doug,
The problem would be, if you welded the flywheel onto the this type of
Electro Auto taperlock coupler, than you could not use the flywheel as a
press.
The center hole in my large flange flywheel allows access to theses
taperlock screws, so again the flywheel press would not work. After I
remove the flywheel, I than loosen the taper lock screws so they are high
enough for a bearing splitter puller bar to push against.
Cannot used a standard wheel puller on the Electro Auto taperlock, because
the transmission pilot bushing is install into the taperlock bushing.
The old motor adapter coupler, that this taper lock replaced, was a press on
type. It takes a 20 ton press that bridges the entire motor to press on both
ends of the double shafted motor. This coupler uses a brass liner, which
shaves off every time this coupler is press on. The key way is a half moon
type, that rotates and locks this coupler even tighter.
To remove this type of coupler, it takes a very large locking type air
driven puller.

Well, if we're getting down to specifics, then remember that "it's" means
"it is." The possessive of "it" is "its", not "it's" or "its'".

me too .. it was rather 'disturbing' to read emails and business
mails from sellers on ebay .. check this out :
'your right' ..
this is not about an rights or duties .. it meant " you are right"
' we except checks' ..
this is not about payments in any form 'except' checks
this is not about checks and balances ..
this is about "we accept cheques"
took me an awful long time to figure out that this new
way was soooo widespread that correcting it is impossible
i learnt to live with it
about capitalization .. all caps means screaming on emails ..
all smalls is almost 'standard' ..
the first letter of any word AFTER a full stop is always to
start with a capital letter ..
but with the newer keyboard based inputting methods on pc's
newer 'punctuation' marks aka simleys and newer ways of
communicating emotions and feelings have become widely
accepted
we can concentrate on trying to be perfect in our grammar
and punctuations, capitalisations and verb constructs ..
or .. more 'normally' .. sadly for sure .. we can 'accept'
the 'exceptions' and understand their 'excellent' ideas born
out of their very valuable experience and expertise.
maybe we can allow a bit more 'flexibiltiy' in groups ..

this is a very different thingy ! it is very very strange that humans can
make sense out of absolute nonsense ! .. the words have to start
and end with the correct letters .. and the letters between the first
and last letters can be juxtaposed in just about any combination
and yet, they make sense ! .. the 'mind' or 'brain' is able to
"interpret" the correct meaning of the wrongly spelt words !
thanks lock .. this came to my mind, but in my 'new member'
status and 54yr age 'wisdom' i didn't actually 'dare' to write

though this is not very well known, but Bruce's message made me think ..
and my wisdom made me 'not post'
but Paul's keen observation encourages me to tell you about 'joining'
of words for a very important reason !
humans can remeber more easily the 'joined' words
e.g. wannabee .. is a person who 'wants to be' something
india (where i am presently stationed) has a very ancient tradition
of preserving knowledge .. in sanskrit verses !
the perfection of 'joining' of words in sanskrit makes it easy to
remember things .. and there are very exact rules for joining
e.g. himalay is actually two wrods .. him and aalay .. snow and home
so is nirvana .. nih + vana ..
so is ramayana .. ram + ayana .. ram's story
sometimes one can see the ALL the words of a line of verse combined
into ONE WORD ! .. so it seems
works in english too .. the rules for joining :
un famous = infamous
un popular = unpopular
un legal = illegal
..peekay
(verses are remembered easier by humans ..we remember poems easily)

Except, I think you meant lightning bolts.
Of course, if you know of a source for lightening bolts, please let us in on
it. They would be the cats's meow for

I would paint the big EV on the hood in clear metalflake over a non-flake base
coat. Then non-flake clear coat the
whole thing. Does that make sense?

very good points david!
personally i do show up in a t-shirt to an interview. if i am looking
for a job, i want a job where they know they need my skills, and then
they will not let formality of clothing determine a thing. if they are
going to pick someone else over me due to their formal attire, it wasn't
a job i would want. clearly, if i were unable to find a job in this
manner, i would swallow my pride and do whatever is necessary, but so
far i've been lucky.
as for formality of a note here, i have no problem if someone doesn't
read my notes because they are all lowercase. it's a style thing i
started back in '92 on all of my emails, throughout my business career,
and have never had a client comment negatively on it. on proposals and
statements of work, Proper Capitalization is adhered to.
i have a hard time reading emails from people who are excessively rude,
so i put those folks in my delete filter. if it is "very painful" to
read lowercase letters, put me in your delete filters ;)
in EV news, my electric fiat spyder is back on the road again, thanks to
help from roy lemeur and some used batteries from eric johnson, thanks
guys! i get stopped almost every day when i head out to my car for
questions about it. i'm thinking i need to make up some fliers to hang
on the side of the car... it's way too good of an evangelism opportunity
to let slide by.

I don't speak for anyone but myself, but I have to admit that my initial
reaction to missing punctuation, lack of capitalization, and poor spelling
is to conclude that the writer is careless and/or poorly educated. Of
course not all who write this way really are, so I guess that's a narrow-
minded reaction on my part. But it's still a genuine one, and I suspect
others react that way too - including plenty of those under 25.
When someone writes carelessly, it hurts me as a reader not at all; but it
may not produce the results the writer wants.
Consider jobhunting. Your skill set may be outstanding, but if you go to
the interview stinking of sweat and wearing torn jeans and T-shirt, you're
apt to lose the job to someone possibly less skilled but who presents a more
professional appearance. That's the reality of the workplace, and the
reality of the educated world is that you'll be taken more seriously if you
write in accordance with accepted standards.
When you post here, feel free to write in whatever manner you like, as long
as you maintain a civil tone. Just recognize that, to some extent, that
manner may determine who responds.

Interesting that they were DOA, w/ apparently no warranty.
I could use some advice as to what to put back in. These are RB-FM-12V-18Ah.
For now, I've mounted a pair of my (very old) Hawkers in place, but it'd be
nice to go back up to 18Ah, from the current 12. (Interesting batts, those
Hawkers. Over 6 years old and never missed a lick.)

> How about current ratings? Also design in a 100% safety margin?
I had an opportunity to look inside a Soleq EVCort EV controller. This
is a very high quality unit built around 1995. Many of these vehicles
are still on the road and working today.
The controller is air cooled by a finned heatsink about 24" x 14" x 2".
The heatsink forms one side of a waterproof gasketed metal box about 8"
thick.
It uses metal-cased hermetically sealed transistors; not the cheaper
plastic parts that are so common. These are TO-3 (diamond-shaped)
packages. The transistors are mounted on twelve metal L-brackets, each
with twenty TO-3 transistors (240 altogether)! At 400 amps, that means
each one switches Each transistor has a fusible 0.07 ohm emitter
resistor to enforce current sharing, and a 27 ohm fusible resistor in
the base so if one transistor fails, it takes itself out of the circuit
and the rest continue to work.
Each 20-transistor L-bracket appears to be wired as a half-bridge; half
pulling up, and half pulling down. Two of the twelve brackets may be
used as a full bridge to handle the field. That leaves 10 transistors x
10 L-brackets = to handle 400 amps, or 10 amps per transistor.
The transistors don't have standard numbers (they are marked with the
designer, Mr. Ohba's name!. But from the size and circuit, I'd guess
they are rated around 300v and 30a; so he used about a 3:1 safety
factor.
That's pretty conservative... but it works!

You can measure a 5% change with good instruments and careful technique.
But I agree that "seat of the pants" measurements won't be able to
detect a 5% change -- this mainly detects psychological changes.

A better way to look at this is to consider how much power your 12v
system uses as you are driving around. Let's say it draws 30 amps. 12v x
30a = 360 watts.
Now, how much power does your propulsion system use? Let's say you have
a 120v pack and draw 60a average; 120v x 60a = 7200 watts.
So, your 12v system is using 360w / 7200w = 5% of your battery power. If
the 12v system drew zero power from the propulsion pack (no DC/DC),
you'd have 5% more range.

Just a reminder to use correct capitalization when writing. If you
want anyone to take you seriously, you first have to take your posts

In my opinion, you might want to consider adjusting your thinking or
you may be ignoring a significant portion of the populace that will
soon be a majority of those online (if they are not already).
This lack of capitalization "movement" started back in the late 80's
when textual chat spaces came into prominance. Those spaces were
considered "informal" communication and as such accepted the lack of
capitalization, incomplete sentances and also word abbreviations
(rofl, kk, l8tr, etc).
The later rise of textual cell phone communication reinforced this
meme because abbreviations and lack of caps made cell text
communication easier and faster. If you have to type several keys
several times on a phone to make a single letter in a text message,
you learn shortcuts.
The result is that an entire generation has now grown up learning this
technique as the "norm", and many of them use it for conversation of
all kinds, even "serious" ones. I would assert that this is considered
perfectly normal and acceptable by almost everyone under 25 years of age.
This method of communication is definitely here to stay and while many
of us over 30 find it glaringly "ugly" to look at, many more simply
see this as the "way things are". I am not advocating that we all quit
using caps and start abbreviating everything. I am just saying that
this represents a major shift in communication technique by the
younger generation and that us older people need to adjust to what IS
rather than what we'd LIKE.
This is totally mainstream now.
Hope this helps!

At an engineering startup we had a guy we interviewed who showed up in a
very faded, somewhat frayed T-shirt and jeans for a nearly six fig
programming job. He was good. We hired him. I have no doubt he did it
on purpose. He wouldn't go for a company that assumed value of things
based on superficial impressions. And a smart company could see the
joke and like the attitude. One that couldn't see it, f*ck 'em.
But you have to be the right type of person to do this. Very unlikely
that simply dressing shabby will have a positive effect for a
nonexceptional person.

Hi EVerybody;
Being EV less sucks! Been trying to do something about that, of late. Dragged
the Nissan Sentra that I have had for a few years, the one I bought in NYC
awile back. Well, when I got it it DID run. but that was a long time ago in EV
years? Pulled it ort least tried, by hand, push, took the full first gear to
MOVE the damn car! The rusty Disc brakes didn't help. Jacked the front end up,
pulled the wheels and pried the disc calipers off, well the left side probably
will hafta replace, as it took a C clamp and hammer to free that one. Right
side turned easy! Surprise! Car will roll, now, off to a good start.Today
building a battery rack in back, it fits 10 batteries, will drop neatly between
the frame rails, so I'll have a trunk, albiet shallow. Those old Sentra's are
nice an' boxy to fit batteries into. The front in the air, figgured I'd try the
motor. Clip leads to a 12 volt battery, this should have produced a motor run?
Huh? Nothin! Not EVen a Zap, when you connect the l!
ead. So left it hooked up and, in gear, spun the wheel by hand. Ahhh! THERE it
goes! Hmmm aren't motors SUPPOSED to start on their own? This one didn't, and
when it ran, sounded like a coffee grinder, lottsa brush noise!. Brushes looked
good, BLACK com. Shit! Gunna hafta pull the motor, get the comm turned. Hope
the comm is still good? My guess that they lugged the motor in Hi gear too
much, but with a Cursit controller, the ride must have been SLOW! Car was
driven/ owned last by the family of the guy that built it and died. So it was
driven to death, when the range gave way, they got rid of it. Hope they didn't
kill the motor, too. Batteries gave you about a 3 mile ride, when I got
it.Pretty hard to kill the motor on that. On the plus side the clutch and
tranny shifted smoothly.
Atfirst I thought I might have something for Power of DC, but I'm not
holding my breath.So that's that. Maybe Dave Cover will get his hub welded and
be up an' running before me?

Electricity is colorless, but when it ionizes the air, the various gases
produce the color.
Air is mostly nitrogen, and ionized nitrogen is blue. Actually, it is
ultraviolet, but the part we see is blue. The rest of the gases in air
provide the other colors.
If the arc is between metals or other material that are being burned
away, they further contribute to the color.
Finally, hot objects glow at anything from red-hot to white-hot.
Lightning is white because the air is intensely white-hot.
I've always thought it would be fun to deliberately blow something like
neon (bright orange) or sodium (bright yellow) through a brushed motor
for drag racing, just to enhance the brightness of the arcing for
theatrical effects.

You may have to go to an auto paint store and actually look at the

with silver. I like your idea of keeping the silver bottom because you
may be able to get away without repainting the lower part of the car. I
have found a couple of ideas that I like (subject to seeing the actual
chips along side a chip of your silver).
The first is a Yaris sedan green 2007 Jade Sea Metallic, the second is
the 2007 Camry Aloe Green Metallic. Visit Toyota.com to find them.

Of course I'll deffinitely go look at the chips. The local Saturn dealership
had either a left over or trade in electric lime Ion until not long ago either,
now I want to go look at it again. Not sure how much I like the toyota colors
(I'll look at the chips though), except the Jasper Pearl they offer on the
Camry Hybrid only. I saw one the other day and it really stands out. Maybe I'll
just go and pick out a color from the book instead. I think I may have been a
bit fixiated on the Saturn color just because it was called Electric Lime.
Too late on the existing silver, it's already been sanded, plus the front of
the car (also partially silver) is not in the greatest of shape. I have a bit
of work ahead of me with the front bumper to make it a nice surface to put
paint on.
Thanks for the suggestions
Later,

Ohh it'll have extra's. I'm doing the prep work and then I'll have someone who
knows what they're doing spray the car. Then I'll probably end up doing the
final wet sand and buff, which I know how to do properly. I don't think I'd be
doing a big "EV" on the car, but I haven't foregotten to have some indication
of it's power soruce. I always liked the "ELECTRIC" logo they used on the
factory S-10 electric trucks. Being EV Bones is located here in town I sent an
email asking about these decals. I guess they'd cleared out all the parts
warehouses of the original GM made ones so they had replicas made so I bought a
pair of those from them. They are a big large, but I was thinking I could put
one on the back of the car under the "Saturn" embossing on the trunk and then
have it copied and shrunk to fit one on each front fender above the Saturn
Logo's. In other words, make it look stock to confuse people.

A simple shorted or reversed cell should not result in a dramatic
failure with a plain series string, unless one continues to drive or, in
some cases, charge the car. (Charging a pack with a reversed cell
should not result in any sort of "incident", but charging or discharging
a battery that has suffered some sort of internal cell failure such as a
short, etc., can generate significant heat and might result in an
"incident".)
Even with a simple series string you must consider possible failure
modes. If you are using regs or some other circuitry that connects
across one or more batteries, what mechanisms are in place to prevent
this circuitry and its associated wiring from overheating and/or
igniting if it fails and the battery(ies) it is connected across
discharge through/into it?
Rudman regs (the most popular device of this sort), are not conformally
coated and so are susceptible to misbehaving if they get wet, etc., so
care should be taken to install them in a protected location. The
connections between the battery and reg should be fused with fuses rated
for full pack voltage because if a battery/cell fails open, the reg will
be subjected to full pack voltage. The wiring between the reg and
battery should be sized to carry at least the fuse's rated current
continuously (otherwise, the insulation could melt or the wires
otherwise fail before the fuse opens). It means more wiring, but I
believe the best way to use Rudman regs is to install them in a central
location, protected from the elements, and use a 4-wire (2 load and 2
sense) connection to each battery. If this central location is a metal
enclosure to keep the regs away from flammable materials, and if the
wire and fuses between the regs and batteries are appropriately chosen,
then I believe it would be extremely unlikely for a reg to misbehave or
cause any larger problem in the unlikely event of a device failure.
Locating the regs in a central location has the additional benefits of
making it easy to provide fan cooling and allowing one to check the
status LEDs of all batteries at a glance.

If "in the back" means inside the passenger compartment, then I would
use a metal cover just as a general rule.

I don't know that it's entirely a fair comparison, but a Chinese-made 15kWh
battery comprising 125 (!) of these cells would cost almost $20,500. That's
more than double what a comparable nicad EV battery from a high quality
European manufacturer (Saft) would cost. With the lower rated cycle life
(800 vs. 1500 to 2500) the cost per mile (or km ;-) would be 4-6 times as
high.
Such an EV battery would be 27% lighter though - not counting the mass of
the many interconnects required - 238kg vs. 325kg. It would also make for
less maintenance. But 4-6 times the cost is a lot to pay for that.

The way to separate the hub from the tapered bushing is as follows:
Take out the 10-24 allen head cap screws that pull the bushing into the hub.
Buy the necessary number of 10-24 screws about 1/2" longer than the originals.
Screw them into until the bottom out in the bushing.
Secure the motor and adaptor to the workbench so it can't move.
Using a steel hammer, give the heads of the screws a sharp rap,
toward the motor. It doesn't require a large hammer or a lot of
force. It's not the force of the blow that does the job, it's the
sharp shock of steel hitting steel.
That should break the taper.
As far as pullers are concerned, all my hubs have a substantial
shoulder to provide gripping points for a 2- or 3- armed bearing
puller. They also have a 3/4" (minimum) hole down the center to
allow the screw portion of the puller to go through the hub and up
against the motor shaft.
Remove the 10-24 screws. If the pilot bushing or bearing is in the
way, remove it carefully. If you damage the bushing, I can supply a
replacement. Hook the puller arms to the shoulder, and screw the
screw in until it makes contact with the motor shaft. Tighten the
puller screw as tight as you can get it with about a 2' breaker bar.
Again, using a steel hammer, strike the end of the bearing puller
screw. Use a little more force than you would on the 10-24
screws. The tightened bearing puller supplies tension, and the
hammer blow provides shock. This should separate the taperlock.
