Sheet metal fabrication of front fenders and rear cover is underway.   


Have you ever seen a car do this ?

Our Build Chronology

Step 1 : Decide on which layout to build first

image1

We decided to do a two person, side by side seating.  Good for a driver and a fun partner next to you !

Step 2 : Decide on drive type

image2

A shaft drive approach would prove that routing and gearboxes were feasible.  Since electric was not viable when the concept started, we decided to use a gas engine.  Electric will be for our next model ;>)  

Step 3: Create 3D Model

image3

Completed by Alex in AutoCAD, the 3D model was a first pass at the mechanical arrangement.  A 3D 'Printed' model was produced.  

Step 4 : Source an engine

image4

To do more details, we needed to obtain the exact engine to be used.  But where to find something we could afford ?  A Honda Civic SI engine from a salvage vehicle became our donor.  But we did need to get it running before pulling it out.

Step 5 : Remove engine

image5

Engine removal required tracing and tagging of related of the electrical and mechanical components.   

Step 6 : Select 90 degree gearboxes

image6

Four right angle gear boxes were required.  Unfortunately, for this concept build, we could not afford to have anything made, so we sourced some spiral bevel 1:1 gears with roller bearings.    Chunkier and heavier than production would be, but good and solid for our concept.

Step 7 : Finalize base components

image7

 This picture show the basic arrangement of the wheels, seats, engine, gearboxes, driveshafts, and gas tank.  With engine and gearboxes selected, weight calculations and arrangement details are finalized. 

Step 8 : Start Framing

image8

Would there be enough room ?  What would the seats feel like ?  First framing sets seat and front wheels.  

Step 9 : Set Front gearboxes

image9

Front gearboxes and steering rack is set in framing.

Step 10 : Strengthen gearbox framing

Front/Rear/Side strengthening of core around gearboxes, steering rack, and anti-roll bar.

 Front/Rear/Side strengthening of core around gearboxes, steering rack, and anti-roll bar.  

Step 11 : Set Rear Gearbox and Engine

Set location of rear gearboxes and engine.

Set location of rear gearboxes and engine. This finalizes shaft lengths, angles, and weighting.

Step 12: Start rear framing

Dragonfly framing

Rear framing begins.  Gas tank, swing arm must be accommodated.


Step 13: Finalize major rear components

image10

Rear Gearbox mounts , Engine Mounts, swing arm mounts fabricated

Step 14 : Fab Rear Swing arm

image11

Rear Swing Arm is fabricated

Step 15: First strength test

image12

  450 lb motor and accessory weight testing.  

Step 16: Luggage Volume test

image13

 Trunk space for Lawn Chairs and Cooler check.  Must have for a fun vehicle !  

Note location setting for air suspension compressors and tank.

Step 17: Fab Driveshafts

image14

 Six driveshafts (3 each side), with CV joints to accommodate motor vibration damping and wheel travel.  In production, these would be shorter/longer versions of what is in your car today. 

Step 18 : Fab Exhaust

image15

 Exhaust with stainless mesh sections for vibration damping, muffler, and Cat  to keep clean air :>)   

Step 19: Major Components Complete

image16

 Last picture of open framing with major components.  Sheet metal to complete drivers cabin begins. 

Step 20 : First roll

image17

 Dragonfly stands on it's own wheels for the first time, and takes a peek outside.  

Step 21 : First Fans

image18

 Front Bumper set, and front framing locations begin.  Air suspension installed.  Raw chassis will be complete once front framing is finished.

Step 22: Bottoms Up !

image19

With raw chassis complete, major components are removed, and chassis is flipped for bottom work.  Once completed, frame will be painted and sealed on bottom before returning upright.

Step 23: Engine Install

image20

Bottom of chassis is completed, and flipped upright.  Major components will begin final install.  Here, engine goes in for final install.

Step 24: Prep

image21

A fan suggests appearing at car show.   Idea of showing chassis is interesting to many.  Decision made, chassis components are installed and prepped for show.  With only 4 weeks to complete, feels like TV show build.

Step 25 : First public appearance

image22

2017 Car show.  Lots of interest and great people.   Thanks to everyone who talked to us, and all the positive energy and comments.  

Step 26 : Fan feedback

Dragonfly at 2016 car show

After listening to the fans, we decided to alter the body style slightly, and create dual intakes with roll bars, instead of the original F1 style intake.

Step 27: Grilling

Dragonfly exhaust

Exhaust system coatings require heat treatment.  Grill is re-purposed.

Step 28: More Fans

Three Wheeler

With exhaust finalized, new radiators and sizing can be determined.   Note that pivoting steering is in place

Step 29: Mock up body options

Dragonfly body options

 Lots of fun creating different body styles, headlight locations, and windshield sizes.    Many options, some really crazy.  

Step 30: Body style finalized, start sheet metal templates

image23

Wood templates give a real life feel to body.  Sheet metal fabrication begins.  

Step 31: Rear Panel

Can your car do this ?

Front Fenders and Rear Panels sheet metal starts.  Rear panel electric opener is tested- very cool.  

Thanks to our sponsors

CSF Cooling

 Thanks to sponsorships from CSF Cooling!    Side radiators, small size, performance cooling...  who can meet our specialized needs ?  Well, meet CSF Racing and High Performance.  They had THE goods, and were generous enough to support our efforts.  We are using two CSF All-Aluminum High Performance King Cooler (#7065), one on each side.   Very nice!  

Air Lift Performance

When we made the first Dragonfly design, we needed to select an air system for design detailing.  Unfortunately, that was many years ago and the old K-Sport control system had no ride height control and was slowly failing.  Searching for a replacement that could support our radical needs,  AIR LIFT has graciously agreed to help sponsor our endeavors.  Their new systems are really slick.  Check out AIRLIFT at https://www.airliftperformance.com/  . More to come as we set up the system.
