Is KG-8 The RO-59 Killah?

[TexasFlood]

Wow. Necro post.

I've moved on to RO-59.

Hah, yes, I was looking for some lube info, something lego you looks to need in the other thread, , and ran across this thread.
I'll check ou the reddit link, thanks.

The Korean guys have moved on to Krytox oils. KG-8 not very popular nowadays. (Maybe because it is hard to get in Korea? I don't know. I tried them on Topre switches, but the effect wore off quite quickly and for that reason I don't recommend them.) RO-59's prime time was even before KG-8. RO-59 is seen as fail proof, but its performance is seen as inferior to Krytox oils.

KBDMania members use two types of oils for use inside of Cherry switch. One type for springs and the other type for plastic sliders. LSD oils are popular choice for the springs and Krytox oils for sliders.

By the way, there were significant amount supply of GPL103 in KBDMania from recent group buys. Thicker oils tend to have performance issues over time and thinner oils have durability issues hence 103 was chosen from discussions between members.( http://www.kbdmania.net/xe/3744764 )

We will see what would be the next choice of lubricant and which lubricant survives.

No lubricant will survive, it's the inherent nature of a lubricant. There is contact, otherwise you don't need a lubricant. And the friction will wear it down, because the lubricant must be weak, otherwise it doesn't lubricate but scratch.

You can see from the chart above, GPL103's service life is pretty long. I thought the experiment results were pretty impressive.

Low graph is better? I.e. lower scores on Dynamic Coefficient of Friction?

[Limmy]

Yes. Low coef of friction is better. The above experiment is from PVC rubbed against painted steel. Plus, the two materials pushed against at 40psi, which I think is pretty significant force. GPL103's performance after 1 million cycles is not much different from initial application.

The source of the graph was wrong in the above post and I have fixed it. The chart is from http://www2.dupont.com/Lubricants/en_US ... tter_2.pdf

Thanks for the info! What LSD oils are you guys using for springs?

[TexasFlood]

LSD? Lucy in the Sky with Diamonds?

I'm just seeing titties. Please rephrase your question.

[Limmy]

I don't think there was any discussion on the types of LSD oils work best on springs. Also, I saw in one of questions on lubrication that ordinary engine oil will do the job as well.

In my experience, thicker oils work pretty well in reducing scratching sound from the springs.

At one time at OTD, anti-shock oil was distributed among members, but I do not know of any detail of that oil. They are said to work very well, but who knows.

You probably see that anywhere you look, like for example this nice wallpaper...
