My first trip back to my workplace with Anisoptera, my recumbent three-wheeled :

Here is my very first attempts :

Finding that the steering gimbal test did not give me satisfaction, I was looking for another option…. Why not try it with a cable system ?

He first had to make a kind of gallows that would bring the cables to the handlebars.

It seemed fun and appropriate to incorporate the cable passage within this bracket.

the main form can open is determined to place the tubes that will guide the cables.

guide wire with brass tubes

The head of the boom is opened to place the guides.

Brass Cable Guide

The brass tubes are placed.

brass wire guides

8mm inner tubes are cut to make the judgments of cables.

cable stop

The brass tubes are replaced by steel tubes whose walls are thicker 2/10ème of mm. these tubes are 6mm internal Ø.

Guides SWR

The holes in the body of the bracket are adjusted to accommodate the cable stops.

tube opening and lime

The cable guide tubes are put in place.

Steel Guide

Judgments of ducts are installed in their housings.

cable stops

Oxyacetylene torch and solder brass.

brazing brass

The tubes made once the solder.

cable guides brazed

The cover is in place and brazed, always brass.

bracket cable guide

The cheeks of the bracket are welded MIG.

gallows

the bracket will be brazed head tube, it must still be stripped.

stem and steerer

The assembly is made, handlebar receives half sheave.

steering cable

Cables and ducts installed, assembly leaves gaps appear steering setting this option "handle up" in a dead end.

To continue development of this bike I decide to mount a direction under frame.

Drilling diameter of 6mm M6 x 30mm balusters.

The posts are cut in two at the height of the drilling.

The wheels are assembled and points Mig.

The double gimbal is mounted on the steering.

A handle is mounted to the test.

The principle of this reference work management, by cons, body double gimbals is not rigid enough, is the next step.

Clin d’oeil…

Cycle Switzerland (JFSGeneva)

With this test, I realize that the system, although functional is difficult to develop and request parts too expensive to be successful.

Based on these findings, I'm looking for another solution.
