Any question answered...

Mind if I PM you a question? It’s a simple one, wouldn’t need all the up to date knowledge on the details.

@PhilDAS Sure, very civilised of you to ask first.

(To those whom I’ve PM’d without invitation, I regret nothing)

Usually the third-party batteries (Amazon, eBay etc) are shit. Best to go with the Apple replacement.

Sound. It’s been a fairly resounding vote for an Apple replacement.

I need to move one piece of specialist industrial equipment that's very heavy and very fragile.
Very heavy as in 250kg weight and very fragile as in one of only a handful in the world and internal sub-millimetre tollerances.
It needs to go across the UK or maybe from London to Spain, imminently.
Which companies specialise in this kind of thing? I have no idea where to begin searching.
Thanks

Martinspeed or Crown could probably do it. They’re art specialists, but handling and transporting heavy, expensive and very fragile things is their bag.

Won’t be cheap tho.

In the scheme of things, 250kg isn’t monstrously heavy. Getting it crated up will probably be necessary too.

Any more details on what it actually is?

Thank everyone. Seems like a wireless box etherneted to the PC sounds like the answer.

What are these screws called? I need a very specific one, much taller than whats on offer on ebay etc

Grub screws

Searching for 'headless screws' will give you the longer versions.

Have a look here.

thank you!

I'd be looking for specialist scientific/laboratory equipment shippers; a quick Google brings up e.g.

https://www.micouriers.co.uk/lab-equipment
https://moveit.com/industries/lab-equipment/

If you want a personal recommendation, I can ask my mate at the Cavendish Lab who they use?

There was a thread on here where people were playing this zombie game where you have to find clothes and make a base etc. Does anyone remember what that game was called?

You definitely want to revive that thread, just beware of @Vesalius. :)

Is there anyway to manage inrush current spikes with an AC motor?

I'm looking at powering one of these from an inverter. It's rated at 250W but I suspect the inrush would mean that a 400w inverter would trip out on startup.

Is there a difference in USB-C cables?
I have an USB-C hub on which the HDMI out doesn't work if I use my Anker USB-C cable. With 2 others I have it works perfectly.

Yeah there's secret specs about what they can transfer, there was in USB-A too but it was less commonly a problem.

Type C is just a plug its nothing to do with the USB bandwidth. Its a bit like power plugs, lots of different types that doesnt really dictate how much power they give.

For example:

• My tablet uses USB 2.0 with a Type C port
  
• My phone uses USB 3.0 with a type C port
  
  

Cables will meet the bandwith from the standard they are desinged to use i.e. 2.0, 3.0, 3.1 etc - not the ports standard.

You will need USB 3.0+ with a Type C plug

Is there anyway to manage inrush current spikes with an AC motor?

Not one that's going to be cheaper than buying a bigger inverter, if the one you have doesn't fancy the job.

@Sumo thanks. There goes the theory of solving every problem with one cable

If you buy a few cables capable of hdmi then they'll do everything else too. Just look for ones that are USB 3.1 Gen 2.

I don't have one yet, but the one I was looking at is only 400w. The inverter thing is secondary so hopefully once I get it I can run it on the mains and work out what the peak draw is.

oh yes please! thanks

He says they mostly use FedEx or get stuff shipped from the manufacturers, but that any specialist shipper should be ok (if reassuringly expensive). His comments on shipping: "careful packing and prep are the most important things; partial disassembly and packing of the most delicate bits may be the best way to go, and potentially use bracing foam inside the instrument. Check manuals/packing lists to see how things were shipped in the first place. Even things like turbopumps can stand vibration as long as there's enough damping on the outside to take the shock out. If you want to pack it yourself to make sure it's securely done, there's always the option of a van and a roadtrip..."
