M6 thread. Into soft alloy. Dont overtighten.

What about using grub screws?
I could use Loctite 234 on them, then use a double nut to lock.

[expresso]

i wonder if you did use those grub screws - then you can use nylon nuts on top and just screw them down without any more loctite - ? i never considered that but if i ever get a chance to build another pack - its not a bad idea

My cells won't be here till next Monday.

I was thinking of getting grub screws and then using 24ct gold leaf on the grub screw.
It will be like plumbers tape. It will fill in the gaps between the screw and thread. Thoughts?

[Scooterman]

I think brass m6 rod cut to into studs would be better. Then use brass nuts and washers. Or phosphor bronze. Both materials are good conductors of electricity.

I suppose aluminium rod threaded M6 might work? Dunno how hard it'd be to thread?

I think Shirley is getting me some copper or copper-plated studs/studding?

I'll leave the gold leaf method opinion as to being good/bad to better heads than mine

Dont like bare copper on low voltage stuff as it oxidises and makes bad contact.

Hmmm does it? I didn’t know that. How about after tightening the terminals were greased to seal out the air?

[Burgerman]

If you clean copper with steel wool, it has already oxydised before you put it down. Thats why you need flux to solder. Alloys of aluminium do that too. Even faster. Which is why you cant solder them.

Its why those battery connectors in the other thread came tinned. And why shirley had issues in a different thread that he doesent understand. Use ring terminals and cable. And use a scotchbright cloth just before assembly with either zinc plated allen bolts or stainless steel ones.

I clean the surfaces of terminals and lugs with acetone before assembling. Once the clean mating surfaces are bolted together any oxidation would surely be on the outside surfaces? I did originally think of flat bottom m6 stainless grub screws. But I read online that stainless is a poor conductor of electricity.

[Burgerman]

All metals are good. Poor is relative. Cross section is more important, and contact area. Clean and good contact is what matters. Acetone doesent deoxidise. Use a scotchbright on soft metals, or some fine grade sandpaper.

Will do

I've heard of scotchbright but have never used it.

What about some wire wool or fine wet & dry, I have some of that in the cupboard.

[LROBBINS]

I'd avoid steel wool - fine bits will be left behind and will rust. Scotchbrite is an abrasive impregnated non-woven nylon and will do a better job of getting into threads than will sandpaper. You should be able to find it in the "pot scrubbing" section of a supermarket or at a decent hardware.

[Burgerman]

Back of a pan scouring sponge. You likely have some already. I just bought a pack of green scotchbright scourers from the high street shop wilko's. Works on alloys and copper. But assemble quickly. So one at a time. The bolt wont be carrying the current the flat contact surfaces should be doing that.

[Scooterman]

Thank you both and the caution about using wire wool, I have a couple of the green scourers in the kitchen.

I like Wilko. As well as household wares, it's about the only place on the high street that sell basic tools and diy products. Some of their tools aren't bad quality for the money.

[Burgerman]

They are cheap. But have a few useful things. Like bedding, household cleaning stuff, garden stuff... But like many shops today they have long lines at the tills. And I dont do queing ever. I went to BQ the other day. Found a load of stuff I went to get. Full trolley of gear. Left it at the till. Went home. No patience for that stuff. If they wont man the tills properly then tough.

[Scooterman]

I know this is slightly off topic but one shop I avoid is Halfords. It’s so expensive for small items like electrical tape, crimps, etc. Maybe their bicycles are cheap, I wouldn’t know. But their bits and bobs aren’t. Maybe that’s where the mark-up is?

PS. I agree with you about unmanned tills

Too embed YouTube vids...

Go to the clip you want on youtube.

Select only the part AFTER the = sign.
So if its link in the bar is this: http://www.youtube.com/watch?v=XflHR16nebU
Then select ONLY the end bit I have put in purple/blue.

THIS BIT: XflHR16nebU and you only want this bit...

Then select it on THIS page, (paste it here then select it) and then click on the button above marked YouTube. And you are done!

So you see on the page:

Code: Select all

UPS has charged me £200 import fees

But I went to pay via Pay Pal. The UPS site screwed up. But it now says "Import C.O.D. (ICOD) charges have been paid."
Nothing has come out of my Pay Pal account. Is it best I call them in the morning?

I did try to call UPS. But they don't work sunday...

[expresso]

i would leave it alone and dont call or do anything - if they charge you - you will receive a paper bill i believe from UPS - check on your paypal acct. to make sure nothing was taken or gets taken out- i dont believe they can just take it from your paypal acct. - they have to send you a bill if they are charging you

the one good thing with the Cells when i got mines - both orders all charges where included - import taxes etc, - my cost was it - nothing extra - its good to keep that in mind when ordering - good to ask if all import taxes included - if not - ask them to declare a much lower value -

matter of fact - i just did that - off topic - an item i purchased from Hong Kong - they put the value i asked them to put - to keep taxes lower - so i expect to get a bill but for ALOT less than it would have been if it was declared at the price i paid.

I think UPS may have paid uk customs on your behalf and will bill you for the amount, plus an administration fee. That’s what fedex do.

I am hoping they are here today.
I will inspect the boxes before I accept them. Any rips or holes and they are going back.
I'm also going to video opening of each box and inspecting each cell. Got to cover your ass

Shit just hit the fan

"A hazardous materials irregularity occurred with this package. We'll contact the sender with additional information"

Looks like I won't be getting my cells after all.

What? That's all the info they gave you?

[expresso]

UPS sucks when it comes to these type of deliveries - who knows what they did handling them - i bet if the package was labeled differently and not lithium Cells - it would have been handled better

hopefully its nothing - or just on wrong truck etc, - sometimes UPS over does it and makes it sound worse than it is -

Thanks guys for the info.

After getting a friend to go to the UPS place in Tamworth.
It turns out there was no ADR paperwork. Under EU rules the driver can not load it for delivery with out it.

I talked to a lady called Jane who had no contact info for the battery company.
But after hours of calls and emails. It is now sorted(hopefully).
Fancy missing the main paperwork!

[expresso]

great you will get them tomorrow then

[swalker]

I'm pulling for you, Terry. I sure hope you get them soon and they work out great.

I am quite anxious to read your report on the condition of the batteries when you get them.

Steve

[Gnomatic]

Well done, Terry. And good luck!

[terry2]

:clap: great you will get them tomorrow then

Hopefully they will come.

I hope the cells are ok. I will post when they arrive.

Well done, Terry. And good luck!

Thanks dude

[terry2]

I won't be getting the cells today or this week by the sound of things.

I have been in touch with sales9 and they are doing the blame game.
Jane from UPS Tamworth is contacting me when she starts work.

These cells may end up being sent back to them. As I'm losing confidence in the company.
I mean...sales9 could of sent a fax yesterday
