the "JD" project 1/9th (rolling chassis) fab-up.

...continuing

Line up of fabricated parts:
wheels, fenders, engine cradle frameworks and springer back fork.

Shaping and tapering upper fork section with miniatures files.
rollfab36.jpg


Fabricating and fit-up, springer front fork suspension.
rollfab37.jpg


Springer Front Fork Suspension fit up.
Much alignment and smoothing to be done beyond this point, but satisfied with progress so far.

rollfab38.jpg


Further alignment of miniature 'springer' front fork suspension.
rollfab39.jpg


Fitting top tapered springs.

rollfab40.jpg


Fit-up: Neck tube.
There is a slight rake & stretch and will monitor that fact during further fabrication of rolling chassis. Adjustments can always be done at a later time.
The key here is maintaing the horizontal frame tube & engine V, parallel to ground level.

rollfab41.jpg


Neck tube installed on frame.
Inner & outer springs installed on front fork.
Good progression with the miniature "JD" rolling chassis, so far.

Frameworks: Fitting rear section.
The 3rd dimension (width) is starting to happen here.
That is encouraging and makes my happy.

Achieving "Critical Mass".
Fit-up of rear ridged (hard-tail) suspension on frameworks. Holding to true scale measurements, tolerances and alignment.

Alex, that is incredible. To be clear, you only use one wire when making your springs and eyeball the spacing? I ask as I found it easier to use two wires, the 'spring' and another of the correct diameter for the space between each spring twist. After removing the dowel/pin/drill bit shank, I have to carefully separate the spring from the spacer and remount the spacer for the next spring.

Excellent modeling!
 
Fantastic. I like that method of making springs. Saul never saw your method before, but it sure makes sense. I have done mine using a screw and twirling the wire into the groves then unscrewing from the new spring.
