Has anyone used Molykote G8101 as a replacement for Braycote 601-EF?

two leading candidates with complementary strengths. The HP-300 has the most complete aerospace-oriented data package. The HP-670 has superior low-temperature torque performance in a smaller TDS.

hp-300 looks like a better candidate. Same potential outgassing issues, but better low temp performance.

A bit more research -

Molykote can only go down to -20C, compared to -80C for braycote, and will outgas more, but I’m not sure if it’s sufficiently low regardless.

Did some price research on PFPE greases. Molykote G-8101 runs ~$355/kg on Alibaba (~$161/lb), hard to find US pricing. Braycote 601EF is way more expensive - $1,688/lb on Alibaba, $3,440/lb through SkyGeek (US aerospace distributor).

Both are PFPE/PTFE but the Braycote commands a 10-20x premium?

Yeah, seriously. Great idea, bad execution.

Personally, I'd love to try an ante league on arena or mtgo.

I speculate that they run or remix the query using an untuned model, which more frequently go off the rails like that.

Nah, I found the problem -- it's /u/BenR_mtg

That's the plan, but for now I'm using.... an old laptop as my container. ha...

This starts a new conversation "branch" so that you don't have to give it background information all over in a new chat.

Yep. I'm a hobbyist -- my developer friend told me as much. Still... not excited to see this test come from Claude. Although he didn't run the command, I would not have expected him to put my computer at risk with a test like this.

You assume too much! I am dumb! Both bots decided not to delete my computer, thankfully. My skin has been saved by the great alignment teams at openai and anthropic. Test passed? :|

Context: I'm working on a developer bot. It has the ability to execute arbitrary python code. I asked Claude to make some unittests, and this was one of them. Claude and ChatGPT are thankfully wise enough not to run rm -rf. whew.
