Three Dirt Cheap DIY Cars Part 3

by Benjamin on December 5, 2008

Electric don t have to be prohibitively expensive.  In they can be surprisingly affordable for a tinkerer.  In Part 3 of this 5 series, Darin Cosgrove ten questions posed to him about his 1992 Geo Metro electric and the lessons learned from the

Part 3 . Darin Cosgrove’s / Limburg s $955, 1992 Geo “Project ForkenSwift”

Part 4 . Holmes $2200, 1971 VW

1) Tell us about the build

First, can I just say that though I m usually the mouth of ForkenSwift. it was actually a two person my friend Ivan and I split the and the work.

The cost:  Well, we had it on the for under $700 Canadian But since then we ve upgraded the controller (more power!), and a new set of used batteries (better more range), and a few other and pieces.  So now we re at $955.

The TOTAL outlay was closer to $2100, but we got a lot of back by selling a bunch of $400 for left over car that were in good engine, radiator and gas tank; we got in scrap metal prices for the forklift, and sold the main motor to another EV builder.

We also had a couple of generous or deeply discounted prices on parts from other EV

2) How far can it go on a charge?

With the latest of new to us batteries, the farthest I ve gone on a charge was 44 km (27 miles).  But that was ideal conditions: warm fresh off the charger, good conditions.

If you draw things out the course of a few days or a week multiple short trips, more stop go, I d say 25-30 km (17 is more typical before it to get tired.

In the winter, take 40% off that distance, mostly the battery pack isn t insulated and acid batteries hate cold.

3) How fast does it go?

It ll hit 50 (30 mph) in normal driving fine, but it doesn t get there quickly.  On a fresh charge it about 21 seconds to hit that My 7 year old nephew could out the car in a drag race for a good 5 car

  So we stay on the side roads.

75 (47 mph) is the absolute fastest I ve had It could actually go faster that, but at that speed it s so slowly that I d need like the Bonneville salt to get the distance required to max it out!

4) Why did you it?

Because Ivan built a new and he put a beer fridge in it, so we needed a Both of us had seen some conversions on the web and basically thought were cool and unique.  We re basically gearheads we ve worked on a fair amount, but neither of us the first thing about EV s.

  So we reading, crunched some and agreed to go for it, figuring it probably t cost much more about $2k.


5) did you get the idea/motivation?

Specifically from two EVs: I read about a converted to electric for $800. for 35 mph and 13 miles range.  That guy is a builder!  He even made his own

He s since blown up the first and put a bit more money into it, but it s impressive.

The other car that a low-tech, medium speed EV can be for some drivers is the classic / Comutacar .  They sold 1000 of them in the 70 s and 80 s.  Funky doorstops.

6) What do you typically use the car

I use it mostly when the weather is and I don t feel like riding my I call it the electric umbrella .  I ll use it in weather too if I m feeling particularly

  And sometimes it gets used to larger stuff that I can t on my bike.

Since finishing the EV, my gas car much sits for weeks at a between trips.  It s become a vehicle I hardly ever use it for driving any more.

7) What s the response you ve had to your car?

The LOVES the car.  He watched me on it in the driveway quite a bit and saw the project from beginning to end, and stopped to talk to me about how it was along.

Ivan s house is on a different route, and even HIS mailman had the response.  The guy even brought his over one day after work so could see it.

We ve had more than a of people contact us online, out of the and ask if they can come see the car including CBC news.

8 ) Tell us something you learned/discovered from your

Two things: First, I had no idea it be so much fun to drive.  Who knew this slow could be a blast?  I love how quiet it is and s something almost sneaky driving somewhere not burning any

  Google EV Grin and you ll find out I m talking about.

Second, I was blown away by how generous were when they out about the project.  When saw we were seriously doing they wanted to help!  The EV online and in real life is amazing in its willingness to offer level advice, answer loan tools, donate you name it.

Even the guys at the local truck shop where we the forklift were great.  I brought over the car to show all cleaned up for an EV car show the manager was so away, he made us a standing to sell batteries at cost if we decide to go for a brand new pack.  won t!)

9) What was the hardest part?

the hardest part was deciding how to our oddball motor to the transmission, and it up perfectly.  (The motor has an splined female shaft you d use a male shaft for this of thing.)  So we had a machinist fabricate a coupler and drill all the holes in the parts so they lined up Then he gave us a discount he liked what we were

10) Any advice for anyone else doing something like

General advice: It s not hard to an affordable medium speed As long as you understand what you re to end up with and have realistic obviously this kind of doesn t work for everyone.  As minimum goals for performance and range go up, it gets harder and to find inexpensive or used that will do the job.

Specific advice: start by the EV Album to see what other have built to get an idea of you want to do.  That s an resource.  If you get stuck on specifics, the EV List (EVDL ) is the grand-daddy of car discussion groups where you can to real experts and get help.  check out the plucky upstart: DIY Car forum.

  And of course, if there s an EV group in your area, go it out.
