Re: Coronavirus pandemic

I got my sputtering system set up for sputtering titanium (in a manner of speaking).

Re: Update on experiment

I am honestly a bit skeptical of that pump -- not that its a bad pump, but that there are probably better ones for a lower price.

Re: Beware of shipping costs!!

Yes, LDS specifically is oddly expensive for shipping charges.

Re: 2 papers about 3d printed vacuum parts

Sadly, laser-sintered metal prints are insanely expensive.

What about printed ULTEM or PEKK? Both of these are available and (somewhat) economic from Stratasys Direct.

Re: Australian Breakthrough Fusion (Duh, Chirp Lasers)

I think there are much better things to do with IC pulsed fusion than generate electricity.

Well that is certainly a tempest in a teapot of Nuclear Blue Glow.

Re: Loads on roads

All I know is that it's incredibly fluffy. A litre of water has more hydrogen than a litre of LH2.

Re: McMaster Carr's oddly inexpensive turbopump

I'm saying it's oddly inexpensive for a brand-new complete turbo, gauge, and roughing pump set.

None of us have brand new turbos, but I still found this quoted price a bit surprising compared to others.

McMaster Carr's oddly inexpensive turbopump

I was browsing McMaster Carr at work today looking for valves (seriously, why are compact, high quality brass ball valves so hard to find?) and was surprised to discover that they have expanded their high-vacuum offering to include turbomolecular pumping stations. https://www.mcmaster.com/turbo-pump...
