Christmas time, time to wrap Patti's shock absorbers up. Fortunately I had to split the work across two holidays, so I did some thinking in the meantime. Pretty happy with how they came up.

They allow some tweaking, there is an adjustable pre-load screw and the weight force on the spring coils¹ can be increased or decreased by varying the distance that the unit has from the pivot point - overall this mechanism is exactly like a nutcracker.

Anyone will notice there is no hydraulics involved. For the time being I did not want to over engineer the design, besides there is no real need yet for an actual absorbing action. However this might change in future.

I also had to split the rear block into two independent units, including wheel, motor and assembly parts.

Pictures do not show batteries, battery trays and electronics box, I still got to figure out how to place all of it. They used to sit in the middle of the old monolithic rear block.

Material utilised are music wire (for the spring coils), aluminium, brass, then bearing, nuts and bolts.
