Help optimizing CNC lathe part

This is the pivot for an improved lid shutter on my (Joeveo) coffee mugs. Bosses are to be staked to retain the wave spring washer and the shutter. I'll be looking for a shop to make these too--get in touch if you'd like to quote.

Is the heat-regulating material potassium carbonate?

It's a wax with melting point around 140°F.

Why is a bolt for a coffee cup so complex? Why does a coffee cup even need all this nonsense?

All that's missing are english threads, or something adorable like M7x0.8, exotic alloys, ceramic bearings or seals or vent channels, like for high vacuum equipment. Don't forget to leave room for the thermocouple.

Our customers, many of them anyway, would like to be able to put their mug in a backpack or purse without fear of coffee leaks. I'd like to accommodate them with a leak-proof, easy-to-open/close/clean lid.

How do you clean the crevices for staked on springs on a lid with through holes to what looks like the wet side?

Maybe I'll invent something called a "thermos" with vacuum insulation and a leak proof lid, one that even doubles as a cup.

Avex / Coleman / Contigo / China.....

If the clearances are right, you'll be able to put the shutter in the silverware basket of your dishwasher and it will get thoroughly cleaned.

There are lots of vacuum-insulated travel mugs on the market (as Jim notes), but they all aim to keep your coffee as hot as possible. Mine keeps your coffee at a comfortable drinking temperature. You can drink it right away without burning your mouth, and it stays hot for hours.

As a hands-on experimenter and prototyper I'd like to see a time vs temperature graph, if you have one. If not I can tell you how to log temperature, voltage and current data for $35 per optically isolated channel.

Don't bet your life on that!

Thanks, that's nice.

I was asked to build a version of Andrea Rossi's E-Cat energy source and quickly noticed questionable experimental procedure and dubious explanations, so I limited my participation to advice. For your project I'm not going to do a free patent search for lid seal mechanisms. I've already dodged one patent lawsuit.

Yeah, nothing like 900 parts to toss in a dishwasher.

Any how does some rediculous rube-goldberg lid help with that? It sounds like there's some phase change material for temp control, which sounds stellar until you look at the absurd container, a problem that was solved long ago.

If you need complexity to seem sophisticated, buy some Zojirushi coffee thermoses with the pushbutton spout, drill a hole in the body and replace the vacuum with your wax.
