📓 Journals kitkat's Emira

A better representation of the ridges and shape of the overall knob.

Coming soon for all of you, I designed this for Darkworks!

It's a Feel's style shift knob but for the Emira/Evora/Exige V6. 48mm diameter ball with a bit more extension for those of us who like to hold shifter from the side and the top. The H pattern matches the OEM one and 70mm overall length.

hope it's a lot heavier than stock to make it easier for those who have short shifter kits installed

I estimate the mass should be around 212g vs the 115g for oem. Those are just estimates based on CAD mass models out of 6061 aluminum so they’ll probably be +/- 2%.

for reference my knob currently is around 165g, so this one edges it out some.

This knob should be a good match for those with a short shifter to balance out the taller knob. It’ll feel good on more grip positions, be heavier, and closer to the steering wheel.

Can you do custom designs? Design is super important.

Also can you do DU or MG?

Can you do tungsten?

WC is tricky to manufacure.

Need to make a mold and sinter the powder and then grind it down.

Its very time consuming and labor intensive.

I get that.

DU may work better.

It’s both pyrophoric and self sharpening

Plus it’s just a waste product so it’s basically free

Depleted uranium (DU) penetrators outperform tungsten (W) in some scenarios due to their self-sharpening ability, which keeps them sharp during impact, and their pyrophoric nature, creating additional fire damage. However, tungsten is inherently denser, harder, and less toxic, but it lacks the self-sharpening property and is more expensive and rare, making DU a preferred option for countries with large nuclear stockpiles.

Key Differences

• • Self-Sharpening:
    DU has a unique characteristic of fragmenting in a self-sharpening way as it penetrates, maintaining its sharp conical shape and improving its ability to punch through armor. Tungsten, by contrast, tends to blunt like conventional metals.
  • Pyrophoric Properties:
    DU is flammable upon impact, creating secondary fire damage, while tungsten is not.
  • Density:
    Tungsten is generally denser and heavier than DU, though both are very dense materials.
  • Hardness:
    Both materials are extremely hard, but tungsten is often considered harder.
  • Toxicity & Radiation:
    DU is a radioactive material and presents potential health risks, although the "depleted" aspect means most of the highly radioactive isotopes have been removed. Tungsten is considered less toxic.
  • Availability & Cost:
    DU is essentially a waste product of nuclear programs and is cheap and abundant for countries with such programs, like the US. Tungsten is a rare metal, with most of its ores mined in China, making it more expensive and difficult to obtain.
