:+1: /\ …… Makes sense to me. 
You are in Canada & know what the shipping costs are there. Works for me however you need to do it to keep the ‘shipping cost’ down. :+1: ….

Oops, sorry.
BlueSwordM could I please increase my order to 30 big and 30 small?
BlueSwordM I’m happy to pay for both the big and small springs now before you order if that’s easier for you.
Same here BSM, I’m with skinny_tie; whatever you want…. Payment in Full, partial payment, down payment, whatever you want…. you call it.
When’s the last date to change our orders?
Not yet.
We are at 1741 big springs and 1257 small springs.
The big spring group buy will end once we get at about 1950 springs.
That is the same thing with the small spring: it will end at 1950 springs.
Please add 6 small and 6 big to my order.
I’d like to add 10 more big springs and 10 more small springs to my order. Thanks!
Please add 20 more small springs to my order. Thanks.
List has been updated.
Ok, one last thing before the springs are being made, as the BeCu 1mm wire has been ordered and shipped.
We initially, or rather I initially, chose zinc as plating as that would be the best compromise between cost, mechanical properties, and electrical conductivity.
However, I have thought about using nickel tin for plating instead. Because tin has a lower melting point, it would be easier to solder a bypass to than zinc, if you actually need to haha, and since it is a bit softer than zinc, it would provide about better contact area with the battery, and provide about the same electrical conductivity. And nickel substrate below the tin.
So, which one would you prefer?
A zinc plating, or a nickel-tin plating?
/\ … As far as I am concerned BSM, whatever you think best. :+1: .
I just want to make sure I’m making the best spring for our purposes.
I understand. Maybe djozz or someone else who is really knowledgeable about this will weigh in with some factual info.
Thanks teacher.
I do know quite a bit about springs know, but I would like to know of people maybe more knowledgeable than me.
Sure thing BSM. But let me be clear, that was not meant to imply you did not know. I apologize if it came across that way.
I say just go with which ever you feel is best. Unless you feel there is someone who knows more about it than you do… go with what you think best.
I have always had good luck with nickle plating in electrical situations so far but either should work.
