I one time put a shaft on a motor by drilling a hole in the "to be attached
" shaft a little smaller that the motor shaft , I then heated the to be
attached shaft red hot , taped it on and when it cooled it locked on and
never came off. It took a few trys to get the right size hole , first try
was to small and when if cooled it cracked the to be attached shaft, .
Are you still selling motor brushes , ? I still need some for my 9"ge.

I guess I should have explained his application more. He has a rotary engine
with two big hair dryers (turbo) on it. Though the fuel pump can be
considered over kill, that is a safety thing. As the pump is designed for
use on 1000+HP engines, having too much fuel or pressure can be dealt with
easily. Not having enough fuel can be severely costly. Lack of fuel can
cause from 30-500000 dollars damage in a split second, depending on the
motor. So putting too big of a pump with a pressure and flow regulator on
it, is just away of eliminating a potentially costly problem. Really fast
racecars can eat a gallon of gas in a second or less. In this guy's case, it
is only about a gallon in 4 seconds. A guy I knows' nitro funny car makes
more hp in one cylinder (over 1000hp per cyl.) which is more than an entire
NASCAR motor, and I think he burns 8/10 gallons of nitro/gas in his 4 second
runs.

On the first discharge (and 2 days later) after a maintenance charge my
Scoot'elec displayed some worrying symptoms when it got down to about 30%
SOC.
The speed started to drop off quite rapidly - down to about 20mph (35km/h)
instead of the usual 30mph (50km/h). It then displayed the fault light and
stopped. Being only a few hundred metres from home (albeit uphill) I
persevered and switched off-switched on (several times) and limped home.
The voltage across the string of 3 STM5-100MRs was 16.5v if I recall
correctly. I fully charged it and have now set about trying to determine if
I have one or more weak monoblocks.
I discharged the scooter to about the same 30% SOC (again after a couple of
days) and it started to exhibit the same behaviour, though not so severe.
Removing the body panels, and putting a voltmeter across each of the
batteries they read 6.20v, 6.26v and 6.28v. The lowest of these concerns
me. Does this look like it is going bad?
Putting them on to charge again, and letting it get into the equalization
phase, the same monoblock was showing a voltage across it about 0.2 - 0.25v
higher than the other two (7.45v against 7.20v though this was rising all
the time)
They have just under 60,000 discharged Ah on them (23,500km on the scooter)

My EV friend Tom went to a car show with his EV , not sure which one , south
of west palm beach . He's got the bug now and has been talking to Jon H and
Paul about us all showing up at one of them with our EV's. No dates set yet
, still at the " when ever you want to " part , I still am trying to get
these trees to stand up again , but will go when ever. Any EV'ers that are
interested let me know .

first thing people hit is the brakes , did you do this and they not stop the

good you were in it and not your kids.
I am happy to say I've never had a dcp blow that the main contactor didn't

did they have one last year, I think last year Jon Halquest went with one of
my EV.s and tried to get in , Yes I'd like to go but even spending $50 to
get in would be a little much to have people promising me great batteries
but not today.
hope somebody goes and reports ...

Thanks for all the helpful information. I did not realize that the MR2 EHPS
always had fluiding flowing through it. I am still interested in making the
PS "automatic" (i.e. no switch on the dashboard), so I will experiment a
bit.
Thanks

Those voltages don't look too bad, they don't indicate
a bad cell. I have 30 STM-180 SAFT NiCd's
in my van,
www.qsl.net/w8rnh/tevanh
When a battery went bad I noticed about 5V, indicating
a bad cell.

I should clarify this statement. The control in my
golfcart was a 72Vdc, 400A unit used on Taylor-Dunn
flatbed industrial vehicles. It worked well for 6
years before the connector was contaminated and lost
continuity. When I repaired this unit I used silicone
sealant. I'm guessing once the control heated up it
released acidic acid that gated on the FET's
improperly (just a guess).
Hopefully I'll have an old Sparrow control to replace
it before halloween (this is our annual trick or treat
machine). A Kilovac would be a nice replacement,
we'll see if one is available.

Hey Steve,
I think that would be great. There are several car shows / meets here in
West Palm Beach. Lowell and I have been talking about taking the EVs out
to one and showing them off. So, the more the better! I think there are
a few car shows coming up this fall in the area. I'll look into it and
see what we can all do. Paul's right here in town, so that would be easy
for him.
My bike should be finished by the end of the month, so I can bring that
out too.
See ya,
Shawn M. Waggoner

The conversion is moving along well on many fronts:
1. the transmission portion of the adapter plate has been CNC'ed and is
awaiting machining of the drive plate.
(see http://www.cameronsoftware.com/ev/EV_AdapterPlate.html )
2. work has started on the throttle pot mounting bracket
(see http://www.cameronsoftware.com/ev/EV_Throttle.html )
3. the existing electrical system has been analyzed and tested. All
connectors not required have been removed (a fair bit cleaner now)
(see http://www.cameronsoftware.com/ev/EV_IndexElectrical.html )
4. I have also revamped the web site to organize the items a bit better.
Any and all helpful feedback is appreciated.

Hmmm 1.5 miles. If they used batteries for storage
> they might get 3 to 6 miles instead.
and if they had used li ion bats and gotten rid of the
hugh electrolisys mecnanism and had a lighter platform
since they didn't need the size of a truck and put in
an AC electric motor reduceing the wieght and regen
braking they might have gotten 10 or more miles from
the same amount of solar cells but no one would have
noticed because this is not NEW technology

In order to do conversions at a reasonable price, gliders will need to be
available cheap. These can come from automobile recyclers, auctions, or used
car lots in various states of repair. A good glider should have:
Good looks with bad engine.
Good heating, ventilation, and interior.
Easy to alter engine bay, and battery storage space.
Room to run cables from engine bay to battery box.
Low corrosion problems.
Large or upgradable brakes.
Good weight handling capability.
Easy to modify heater.
I agree that the low maintenance aspect of an EV needs to be pressed and I
agree that flooded batteries are not low maintenance unless there is a
central watering system.
If a platform could be identified that is reasonably easy to adapt to
electric, kits could be built to support an options list such as:
Batteries: ()Optima,()Orbital,()ThunderSky*, ()Kokam*,()Saft, etc.
*=Includes BMS
DC Motor: ()9inch ADC, ()8 inch ADC,()Kostov
DC Controller:()Z1K, ()Z2K
DC Converter: () 30 amp, ()60 amp, ()90 amp
AC Motor:()Siemens 30 kW,()Siemens 45 kW,()Siemens 70 kW,()Siemens 85 kW
AC controller: ()Siemens Simovert, ()Siemens Simotion
Charger: ()3 kW, ()6 kW,()12 kW
Battery heaters:()yes,()no
Each option could have a price attached to it. Some standard items that
would need to be included would be: a kit to convert the heater to a ceramic
element, main pack fuses, main contactors, emergency/safety disconnect,
charger inlet port, main pack conductors, etc.
I would propose to build two kits. One for a rear drive two passenger car (a
Fiero or 914 type) and for a front drive four passenger car (a Metro or
Civic or even Camry size). Each would need to be a car with good parts
support as well as meet the requirements of the second paragraph. I don't
know the newer cars well enough to judge how well any of them meet the
second paragraph requirements.
I would think that electric Miatas or Civics or Camrys might sell reasonably
well if priced right.

I thought about this myself and came up with a couple
of relays and 2 fans, when connected to 220 the fans
are connected in series, when connected to 110 they
are in parrallel. I think I ended up with 4 relays
total, that way I could have both a 110 and a 220
receptacles on the car. The extra relays disconect the
unused receptacle so you don't have the 110 hot while
charging from 220.

I just read about this for the first time today. We rebuild hydraulic motor,
though I haven't the faintest idea about how the systems work. The reason
why I never checked this thread before, just no time. Anyway, I do have a
couple of companies that are customers of mine that build custom systems.
Mostly cranes, lifts, etc. But their stuff is "oddball" so to speak, so they
could have some knowledge of doing not off the shelf things like you
described for your steering. Also if I recall some forklifts have hydraulic
power steering as well. If you email me at [EMAIL PROTECTED], I can
pass the email onto my customers. Try to include as much info as possible in
the email, or a phone number that they can call you at to get more info.
Again my apologies for not seeing this sooner.

I always have the engage contactor connected to the throttle peddle so when
you press the microswitch on the potbox, there is a click each time to apply
power to the controller. The main key switch contactor is still used also. I
also have a bypass full-on contactor in case the controller opens when
there's a MACK truck behind you. Always use these for safety when building
an EV or Ebike. Mark

Hello to All,
What could be better reading, than Rod and Rich going at it?

I'm glad you posted this. In addition to all that hits the list, there's a lot going on
behind the scenes that sometimes gets forgotten, or simply taken for granted.
Nutty as he is, the Madman has been and always will be, a great friend, and especially
this year, has been a huge help in getting White Zombie to perform the way it has.
> As Dennis said: "The proof is in the time slips."
Yes, how true. I've got time slips that prove many of the Madman's ideas work well.
I've
got one posted at the Zombie's EV Album photo page that shows the Wayland-Rudman
collaboration works to the tune of 12.99 @ 101 mph.
Thank you Rich, for all the hard work, whether it's those wonderful chargers (thanks
also
to Joe Smalley) that get the beast charged up so quickly trackside, you driving down to
Portland with hard-to-find sticky drag radials in the bed of your truck, or the late
night
argument sessions over pie about if one of my crazy ideas will work or not.
See Ya...John 'Plasma Boy' Wayland

Okay folks,
I've lurked for a couple of years and posted occasionally about my progress on the
conversion of a '71 Karmann Ghia coupe. The coupe was a compromise, due to the dearth
of decent cabriolets available at project pricing.. Besides, you need a coupe to
support all that extra battery weight, right? Well, Eric Ryan, former director of the
high school www.EVChallenge.org organization proved me wrong with a tire-smoking 1965
Ghia Cabriolet; "Ghost Dancer". However, fried Hawkers and a new business venture led
him to give up the Ghost, but not before unceremoniously parting out most of the
conversion components on EBay a few weeks back. Well, I invervened before the gas
tank was refilled, and purchased the glider this weekend.
EV buddy Doug Weathers, who's Ghia conversion is storied at
http://learn-something.homedns.org:8100/weblog/ghia/index.html
agreed to help me retrieve the glider and tow it the 520 miles home. After a great
drive down from Portland over the snowcapped Cascades and past the formerly forested
plains of central Oregon, we wound our way through the walnut groves of Northern
California to Chico. The glider was as promised, gleaming Midnight Mica Blue in it's
rechromed, but gutless glory. We sealed the deal, loaded the truck with spare parts,
hitched up the tow bar, set out for the Sierra Nevada Brewpub to toast our success.
Less than two miles later, as I execute a legal U-turn to access parking, the custom
extended tow bar that has faithfully pulled Ghias over 5000 miles for me cracks apart!
Yep, one arm of the wishbone snapped off with a terrifying "POP", and the sound of
steel meeting concrete is accompanied by a shower of sparks as the beautiful Ghia
begins gyrating wildly on 1/2 of it's tether. Fortunately, we're pointed uphill, and
manage to ease the rig to a stop without smashing the Ghia into my truck's rear
bumper. Only one small dent and a scratch under the nose will linger to remind me of
that terrifying moment.
Fortunately, an extra (shorter) tow bar was included in the parts stash, and after a
short jog to the Wal-Mart for a smaller hitch ball, we're able to complete our dinner
plans and make it home uneventfully after 500+ miles of very slow and wide turning
maneuvers.
Now the 'vert is safely stashed in my garage, awaiting the transplant of a modern
(1971) independent rear suspension pan with custom reinforcement and battery boxes,
and I am, once again, broke and happily exhausted.
Thanks for your time,
Jay Donnaway

Great post! It looks like John has some northern competition in the story

Your batteries are in normal condition Matt.
The optelec charger is a batterie killer, don't expect having total nicad
range, expected life and same resting voltage for your 3 blocks.
I see same voltage difference than you mon ami.
A friend (ALEL) has modified a curtis charger to replace the optelec, it is
1/2 slow (better for batteries lifetime) and you obtain more range, less
gasing but for servicing charge you still need the optelec or the TEP96 (i
know you have both :^) to reset the ECU.
Seems you are seeing like an overtemp controller problem which enabled fault
protection, looks like same result than eco mode (35km/h max with reduced
acceleration)
Don't worry about that until controller stay always at this low performances
level, i already seen this symptom coming and disapearing itself quickly on
one scooter, i was on the way to test/replace excitation mosfet but problem
dispeared itself during monitoring ride.

Lol Jay, sounds like you have the same kind of adventures pursuing your EV
dreams that I do. Somehow makes it that much more worthwhile, though usually
upon reflection . Reminds me of outrunning 9K lbs of G-Van and trailer
coming down the icey Grape Vine in early winter when the trailer brakes
suddenly decided NOT to work. Since my buddy Tom was driving, all I could do
was hang on and quietly panic. He did a great job keeping us on the road and
everything was well. Good thing that I wasn't scheduled for a proctological
exam anytime soon afterward. Good luck on your new project, I have always
loved Ghias and especially look forward to seeing (another) EV version on
the road. Regards, David Chapman.

While looking into options for our broken transaxle on "Gone Postal" I
surfed to find the top FWD VW drag racers and what they run. I also called
one of our sponsors Autotech Sport Tuning www.autotech.com. It turns out
that Quaife makes a rather expensive but effective solution called a six
speed dog set. It includes all new gears except reverse. These gears are
like those on Japanese motorcycles where there are dogs that engage in slots
in opposing gears to engage the gears. They are 50% stronger than the stock
set up and 25% stronger than the Quaife synchro gear set. I spoke with Hodi
of Hodi's Performance who is a mechanic on the worlds quickest and fastest
FWD VW. It has 750 HP and turns 9.69 seconds at 145.16 MPH.
http://www.gtrmotorsports.net/GTR_racing/bios/brianbio.html They just run
the synchro gear set up. They were breaking third gear when they were
running 650 HP but now that they are running 750 HP they are breaking fourth
gear every ten runs. I asked why they didn't go to the dog set up and he
said it was because of the expense. The dog gear transmission gear set would
be sponsored to us for $5,500.00 which is and enormous amount of money but
redesigning, adding more weight and building a new transmission is also
expensive. We have no where near the horsepower they are running in their VW
so I believe the dog gears would be the solution for our project. This whole
thing just reminds me of how far we still have to go to harness our power
and dial in this monster.

Maybe a dumb question, but could you use the GM 475 transaxle? I believe it
lived behind 400 HP 455 Oldsmobile and 501 Cadillac engines.
