I searched all over the internet and couldn't find the ones I wanted to show
you. But I found these:
http://www.sjdiscounttools.com/kdt2279.html expensive $10 ea
http://www.sjdiscounttools.com/kdt205.html less expensive $4
They're spendy. I got one from Batteries Plus here in Anchorage for $2. Its
just a rubber strap with hooks on each side that hook into the lifting eyes on
the batteries.

The inertia switch that Chip mentioned is available
from EV-America. I bought one and plan to install it
in my S-10 Conversion. I don't remember what they
cost, but it wasn't that much as I got a couple of
items for about $80 including shipping. Here is their
link. Hope this helps. Dan Eyk

The orange cable of choice is the Carol Super Vu-Tron (Class M, CSA/UL
600V 90C, Orange). Unlike many welding cables you might stumble across
on the web, this one is CSA/UL listed. The class M is even more finely
standed than the more common Type K "flexible" welding cable. As I
recall, 2/0 Type K has something like 1300 strands while the 2/0 Type M
has about 3300 strands.
You are unlikely to find anything but black and perhaps red at a local
welding supply place, but you may find the orange cable at an electrical
supply distributor. I bought mine from such a place local to me and the
price was competitive with anything I found online in black. The
distributor did have an 8m (~25ft) minimum order, so worthwhile to buy a
bit more than you think you need than to have to go back for a few
meters/yards later and be forced to buy extra to make the minimum.
However, they either had the cable in stock or could have it transferred
in from another warehouse for the next day, so very convenient.
A few other possibilities I searched up back when building my EV:

You can see how the Super Vu-tron looks in use here:

I've run my cables in non-metallic watertight conduit and haven't
bothered marking them, but I've got bright orange flagging tape for the
purpose should I get the urge. Flagging tape is that non-adhesive stuff
that you might see tied around tree branches, etc. marking a trail or
used by surveyors ocassionally.
For low current situations, orange jacketed 2-conductor extension cord
is another good solution. Al Godfrey has taken that approach for the
balancer wiring on his 928 conversion, visible in the underhood shot
here:
<http://www.austinev.org/evalbum/455>
Another approach is to use orange split-loom. I've got some, but
haven't used it because I don't really care for split loom ;^). Lee
Hart has cautioned that often such coloured split loom may not have any
safety/regulatory approvals as it is sold in the aftermarket for looks
and so may melt or burn where other materials would not.
Cheers,
Roger.

Granted, the Sunrise is AC, had good batteries, is/was extremely
efficient.
But alas, as I heard the rumour, it was driven very slowly on the range
testing track for hours upon hours.
Sorry for the slow response; I had to dig up some numbers for you.
In May 1995, James Worden raced the Sunrise in the Tour de Sol, going 238
miles on one charge. Rather than dawdle, he got a "ticket" for speeding
from race officials for exceeding the posted speed limits.
In Oct 1997, Worden drove a Sunrise from Boston to New York City, about
270 miles, at normal freeway speeds.
I Was THERE! I chased, or paced them on I-84 im my Diseasel Jetta,
taking a few vids, IF I can dig them up again? I'm going through another
Tech Opera as I just bought yet ANOTHER Sony Handi Cam, to vid at PIR in
a few weaks. OF COURSE the damn new camera won't play back my older
tapes!Digital format? Why the hell don't they tell you that in the laundry
list extoling its many features??Tech support IF you get through, pushing
buttons waiting, endlessly listining to shitty music on "Hold". to get the
guy whose language ISN'T English as a native one, and is clueless as I am.
I can read the damn manual, I need the questions that they fail to cover
in a small fone directory size manual! I need a camera that will play back
years of Woodburns, Power of DC 's and Whatnot, to put on DVD discs, the
format of the moment. Will there BE DVD's in say , 10 years?Or some other
moody, system you gotta be a tecky to make work?
While in Rant mode; Would you build or buy? I would BUY a EV-1, or
something like that, turnkey thing? You Bet., in a hart beat! Got better
stuff to do than wrenching in the garage hacking a car body into
electric!Yeah, It's a nice hobby, but I liked the EV-1 a lot better. Just
hop in and go!By now there woulda been used ones as there are used Prei out
there, for the asking.I'd be down at the Trolley museum, EV-1 plugged in,
and helping restore some of our electric Heritage; Products of say, the JG
Brill Co, or Jewett 100 year old interurban car, on and on. Real working
examples of what shoulda been for years longer.See "Taken for a Ride" movie.
Back to the story;
In closed-track range tests at low constant speeds, the Sunrise went over
400 miles on a charge. (The quoted 373 miles was in one test with media
present).
Bob Aronsons Mars too Renault R-10 conversion used to shine at those!
HE used to do a couple hunnert miles too, at 25 MPH. On the hiway he was
good for 50-70 at 55mph, right lane. Of course this was with a TON of
batteris, Tri Polars, no less!Car weighted 4200 lbs! We'd leave tire tracks
on RR rails at crossings<G>!Bob had no truck with low voltages, he was
running 120-to144 back in the daze when most EVers were doing 24-48volts. Of
COURSE his cars went well. 110 amps at 55mph in the Mars.
So, while the "up to..." numbers aren't very meaningful, a range of 200+
miles even in normal driving is pretty impressive!
Of course, these were all done with "unobtainium" GM/Ovonic nimh
batteries.
Lee is holding out,as I, that a GOOD solid 100 mile range plus with
good Golf Cart attaininum batteri is possable, NOW, today, Thinking of T
125's or T 145s For now, when Aunt Tilly in Toledo kicks off and leaves ya a
few hundred thou, so you can upgrage to a123's. In the meantime, we can work
on other linitations, here, like the designed from the ground up CAR body.OK
so maybe we can't duplicate the EV-1 in all its hi tech glory, but we can
pare the weight down, so Sunrise will be FAR lighter than a Jetta or
Rabbit?Aero, too?
The chicken an' Egg thing? Enough EV's running around that the Charge
stations come on line? Hell! I'd settle for some 240 volt OUTLETS to feed my
PFC 20.
Seeya in a few more daze

You can get orange cpvc which is intended for fire sprinkler systems
(sometimes known as "fire pipe" in the plumbing trade). It's easy to
work with--just like regular pvc. A good plumbing store can get it for
you.

I am considering bonding an integrated IGBT DIP module to the aluminium
base of a watercooled box.
Is this sensible?
Is there an issue with strain in the IGBT module if the aluminium
expands/contracts at a different rate to the module?
If this is a workable idea then what adhesive has good thermal
conductivity whilst having a bond which is not too strong (in case the
module needs removing)?
thanks for any help,
Tom Ward

Ah, that's good to know. The conduit I used is the flexible stuff, but
I was thinking of using a length or two of rigid PVC to carry the
charger connections from the rear of the car to the engine bay.
I wonder if I might be better off sticking with grey rather than mixing
colours and confusing someone into thinking that the grey flexible
conduit is safe to cut through since the orange rigid lengths ~must~ be
the high voltage ones? ;^> Maybe someone will solve my dilemma by
advising that the flexible conduit is available in orange also?

Roger.

I didn't buy any batteries when I walked into the shop so I figured the $2 was
worth it because I needed them "now".
My battery supplier who delivered the batteries did so when only my wife was
home and didn't leave any of the "free" lifting straps.
But they do work well enough for jockeying the batteries around.

I feel for you, Bob. I had Sony's top-of-the-line Hi8 camcorder, and
when it was stolen a couple years ago I had a heck of a time finding a
(then) current model that would play back both my 8mm and Hi8 tapes.
Ended up having to go into a higher-level Digital8 model in order to get
this ability since the lower end stuff couldn't do it.
Looking at the Sony (Canada) site, I see only a single Hi8 model listed,
and no Digital8 model turned up:
<http://www.sonystyle.ca/commerce/servlet/ProductDetailDisplay?storeId=1
0001&langId=-1&catalogId=10001&productId=1001051&navigationPath=32080n32
082>
Are your old tapes 8mm or Hi8? If they are Hi8, I think you have more
choices, as I recall the challenge I faced was finding a camera that
could still handle the plain 8mm format as well. Anyway, the model I
ended up with was the DCR-TRV350, which has the ability to play back 8mm
and Hi8 tapes, but only records in Digital8 format. It has USB and
Firewire ports that make it fairly easy to get your older analog tapes
into the PC for putting on VCD or DVD, etc. In fact, it also has both
composite and S-video in/out that allow you to play your analog VHS
tapes into it and stream the digital output from the USB or Firewire
ports to your PC before you find you can't buy a new VCR either ;^)
Good luck,
Roger.

It is, but I've found that it's extremely expensive. Flexible
nonmetallic conduit in orange is typically a variation rated for high
continuous flexing (2 layers of PVC with a layer of nylon between them)
which I can't find for a reasonable price anywhere. The cheapest I've
found for 1.5" (large enough for 2 2/0 cables) is approximately $1100
for a 100' coil. Compare to the normal grey stuff I just bought at less
than 1/5th that price.
Incidentally, I might as well mention we're starting a conversion
business in the Austin, TX area, and as a side business we'll also be
selling certain parts and materials. Some relevant items we'll be
offering are orange Anderson connectors of various sizes and bright
orange 600V fine-strand welding cable, custom lengths; we'll even crimp
ends on (with boots and heavy adhesive shrink-wrapped hex crimps, the
whole nine yards).
If anyone's interested, contact me off-list.

The Battery vehicle society (www.batteryvehiclesociety.org.uk) had organised
a track day even for last weekend and I'd managed to screw my motorcycle
project together to a sufficient degree to take it down.
http://www.compton.vispa.com/Pictures/freccia1.jpg
http://www.compton.vispa.com/Pictures/freccia2.jpg
http://www.compton.vispa.com/Pictures/freccia3.jpg
These are BIG images, since I haven't edited or compressed them.
The Freccia was loaded onto my bike trailer (nice trick by yourself) and
strapped down and I began the 2 1/2 hour drive down to the Haynes Museum at
Sparkford. The weather was pretty good, but the traffic wasn't and the first
40 miles took the 2 1/2 hours. Still I arrived at the B&B at a reasonable
hour and got a fair nights kip. The next morning was showery, but after a
leisurely breakfast I set off to the Museum and rolled into the carpark and
down to the far end where the test track is situated. One or two other BVS
members were about and I got one of them to hold the front brake whilst I
undid the straps and then rolled the bike off the trailer. There were quite
a few admiring comments about the build quality and the BVS chairman took
the bike for a quick spin around the carpark. The primary drive belt was
jumping teeth a little, which it hadn't done before, but I'd had the
batteries on an extended charge (they were discarded Optimas from my
Scirocco EV and had been sitting for a LONG time) and had a little extra
pep.
Haynes had helpfully allowed us use of a garage around the back of the
museum and I transfered the bike and charging kit (variac) into the garage.
The BVS chairman and I took a look at the track
(www.haynesmotormuseum.com/commerical-services/images/circuitmap.gif) and
spent some time moving tyres to mark the layout we wanted. If run clockwise
there is a tricky off camber right hand bend at the end of the Duesey
stright with no run-off, just Armco and we didn't want any incidents. We ran
the track counter-clockwise and used the most twisty layout we could
(running around 'spring back' in both directions with a dividing line of
tyres) to keep top speed down.
Not that many people had turned up yet, but I donned my jacket and helmet
and took the bike out for a few sighting laps. The track was damp/wet and
there were some very slippery bits, particularly the big brown slugs! I only
did three or four laps and then rolled back into the garage and put the bike
on charge. At this point I really should have checked the motor temperature,
but I was busy getting the variac charger dialled in and connecting the
current clamp and voltmeter.
The rain took a break and with a brisk wind the track was drying rapidly, so
with the charge tapering off I climbed into full 'track day' gear; One piece
leathers, Scott Carbon/Kevlar armoured gloves, Sidi Vertebrae boots, and HJC
full face helmet. Once suitably caparisoned, I climb onto the bike and roll
it out to the track entrance. A timing marshal is selected and I set off for
ten timed laps. I take it easy through the off-camber right hander and then
accelerate up the hill into a left-right-left complex. I muscle the bike
into the 180 degree sweeper at the top of the hill and using all the track
at the exit, accelerate down the hill sweeping left then right before
entering a tight and slippery hairpin right. You seem to have to wait
forever before you can get the power on again and then almost immediately
you're into an equally tight right hand hairpin. You can treat the exit from
this bend as the entrance to the next and just let the bike run out to the
Armco before starting then next lap.
I'm starting to get a little heat into the Flintstone like 15 year old
Dunlop Arrowmaxes and getting used to the relatively heavy handling. The
front disc is clearly warped so I'm careful to avoid a lockup and subsequent
lowside. As the laps roll past I'm carrying more speed through corners and
using (I thought) less throttle. I get the two laps to go signal and then as
I finish the ninth lap there's a sudden loss of drive. It sounds as if the
chain might just have jumped off the front sprocket and I roll off the track
before inspecting the problem. The chain is still in place and lifting the
tank cover reveals flakes of solder. The bike was geared to do 60 and this
was clearly too high for the poor etek when subjected to so much full
current acceleration. I was only getting to 40 or so and the motor has
overheated and spat out the solder out from its peripheral connections. It's
only the morning of the first day and I've already broken the bike!
I put the bike back on charge, making sure the energy meter is reset as
energy consumption is part of the competition. My lap times were very
consistent, which is always a nice thing to see, but I'm still dissapointed.
I climb out of my leathers and back into 'civvies'. When the charge is done
the energy meter reads 0.86 Kw/hr which is around 130 Wh/mile.
Later in the day my luck improves. Trevor Lees of Lemco turns up with a
Mercedes Smart conversion and a US made 'Drift' motorcross bike. This has
been upgraded from an etek to a Lemco and Trevor generously donates the etek
to replace my dead one. The shaft is different from mine so sadly I can't
fix the bike on the spot.
Later on I ride the 24 volt Lemco powered Suzuki X7 conversion the chairman
has borrowed (we had to take the siezed front caliper off) and better his
times on it. I also ride the Drift, but the batteries are nearly flat after
10 laps. Nice bike, but off roaders are not my style.
All in all a great weekend. Not the best turnout, but we had 10 machines
from bicycles to cars on track and everybody enjoyed themselves.

An electrician friend advises that you can bend regular pvc (the "rigid"
kind) with the suitable application of heat. He says that out at
jobsites they used to stick a piece up the tailpipe of a truck! I
suspect that heat would allow you to bend the orange stuff, too, though
I haven't tried it.

Now that you have the lifting straps, there is a easy way to lift the
batteries in place. As you get older at the ages of 70's to 90's, I use a
modified engine hoist with a long extend boom that I can rotate for putting
my batteries in my EV. I use a the hook around the lifting strap with
plastic clamps on both side of the hook, so the engine hoist hook stays in
the center of the strap.

Paul,
Nice looking bike! Sorry about the motor mishap.
Hopefully the Alltrax survived the motor meltdown.

In the owners manual that came with my bike computer I'm pretty sure it said
to count the distance for multiple revs and then divide to get an average
circumference. I don't know how much difference it would make, but it
should help if the accuracy (or is it precision?) of your tape measure is
fairly coarse.

How would that work with an EV?
Your RPMS on a unit like that generally just snap onto your spark plug wire
and read the pulses of electricity?

ahhh... something i know about.
almost all bike computers have a remote sensor that
reads the signal from a
magnet mounted to a spoke on the wheel (for speed).
higher end computers may
also have an additional sensor to read pedaling
cadence, detecting a magnet
mounted to a crankarm.
most computers can be calibrated to work with a wide
range of wheel
diameters, and as long as you can get the fixed
sensor mounted within half
an inch or so of the wheel on which the magnet is
located, you should be
able to get an accurate speed readout.
i'm not sure if the cadence sensor, or more
specifically the computer's
display, will handle the rpm values that you can
expect in a typical EV's
electric motor though, so using the cadence function
for an rpm display may
not work.
i recommend using a wired, as opposed to wireless,
computer in any EV. i
love wireless computers on my bike, they're
incredible. however, there's
simply too much metal on an EV to get a reliable
signal from the sensor to
the head unit. the sensor transmitter just isn't
strong enough.
we sell a lot of computers here...
http://www.speedgoat.com/catalog.asp?cat=120
i recommend cateye or vetta. they're simple, cheap,
and reliable.
another option would be to look at GPS units for
speedo, etc. although
Speedgoat sells some cycle-specific Garmin units, i
don't think they would
be as effective as some automotive-specific GPS
units.
feel free to ask any questions about bike computers
in general, or certain
models specifically.

You must be able to get shrink wrap tubing in orange. Here's a candidate:
http://www.buyheatshrink.com/heatshrinktubing/2to1polyolefin.htm
I see diameters from 3/64" to 6", so you should be able to find the right
diameter. A 50 ft spool of 3/4" is $25.

Sorry, I hate to be the killjoy, but please take your question to a more
appropriate venue.
I'm late catching this (been very busy with work and some minor disasters at
home; no worries, as I say, minor ;-) However even now I would ask other
EVDL members not to post further responses to this thread. The matter is
better discussed on one of the many quasi-hybrid forums. Some examples :
http://www.greenhybrid.com/
http://groups.yahoo.com/group/honda-insight/
http://groups.yahoo.com/group/honda-hybrid/
And those are just a few. A web search will turn up many more.
The EVDL isn't the place to discuss vehicles which derive all of their energy
from gasoline, except for the subject of converting them to BEV or plug-
hybrid drive. There are many other (better) places on the 'net to discuss
these vehicles.
Thanks.

I wouldn't depend on any kind of adhesive as the sole means of support in an
application like this. I assume the IGBT will be producing heat, so there will
be thermal stress on the bond.

I think it's a good idea, and worth a try. I've seen evidence of water damage

you can if you have the center of gravity lower than the axle of
the wheels.
ok, the front wheel will have some load, but very little. it should self
balance even without it. Think child swing..

The only negative thing I've ever heard is issues with
a binding clutch cable or some cabling (throttle?)
