I just realized that Beryllium is a Group 1: Known human carcinogen. The MSDS sheet says that the beryllium copper alloy is pretty much safe, but please be careful and make sure you're wearing a mask and goggles when you're cutting it with a Dremel. http://nsrw.com/MSDS/msds-class%203.pdf[/quote]

I was wondering when that would come up.  I found out about that a long time ago when some article talked about why it'd be good and bad to use this material for bicycle frames.

The low mode should be lower.

I think I was reading this wrong, it's not 5 cents each once you hit 1000, right? There's no decimal point.

A little help for the bifocal brigade, please. Tongue Out

0.525 - 53 cents each, rounded up.

yes that’s .53 cents or just over a half dollar each if we can get em at the 1000 level.

And please, don’t use lead solder while chewing soldering these springs.

Thanks. I'm just starting modding and looking at mostly 17mm to maybe 20mm drivers, an 8mm spring seems a bit large unless there are no 7135's on the battery side. Not sure what I would use them in, direct drive lights?

What we’re pricing here is about 5.5mm. I’d give more specs but they’re not in a hurry to talk to me.

I have been having the same lackluster response from another custom manufacturer of beryllium copper springs and stampings. How strange that a business would be so callous toward potential customers. Granted this isn’t the volume that could get a promotion, but still.

American business?

Yup, a ‘Merican company. Maybe if I had a business license number they would take me seriously.

These springs will have a lower resistance in comparison to copper braided springs due to the materials in use and the fact it’s a solid chunk of wire rather than thousands of thin strands (relatively) loosely packed together.

Wire and braid are soft copper, while these springs have beryllium added for hardness, so the braid probably conducts better per area.
At high frequency braid conducts better per area than solid wire does because its inductance is lower, but at DC it is only the area and length that matter.
However it is simpler, easier and neater to use the spring also as the conductor.

5 × 8 × 10 mm is just fine for Minimag tailcap mods. The stock 105C spring is often too short( Qlite driver being a pleasant exception). Instead of 5×5×5 it’s 5×5×7 and is long enough to have some spring to it.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

Maybe, but it's probably easier and faster to get it from Chinese companies, especially when they refuse to deal with you.  If that American business goes under, they only have themselves to blame for sending their jobs to China.

It’s our system. Selling to an individual puts the company at risk for all kinds of issue, including lawsuits from possible injury by people that didn’t know what they were doing in the first place. By selling only to approved businesses, they have some assurance the product will be in the hands of those accustomed to using the product. With our judicial system awarding people for being idiots, is it any wonder manufacturers are overly cautious?

You are no doubt correct, DB. I often long for the day when we were responsible for ourselves. If I should do something foolish (if, hah! Count on it!) then it’s my own fault and I will have to deal with the consequences. Not like I’m going to hold scalding hot coffee in my lap while driving then sue McD’s for my stupidity. But you are right, the litigeuos environment we find ourselves in has changed the landscape for the worse I’m afraid. I’ll have to give them a call on Monday. A message worth hearing is worth repeating.

hi, any chance of knowing the exact form (especially the ending of the springs…)

I didn't even think of that, sorry, count me out. I only use 63/37. Solder without lead in it is too hard to... well, to solder. YeeeshSealed

I think that was sarcasm? :bigsmile:

I was concerned about the carcinogenic properties of beryllium and Dale said not to ingest lead too. Silly

I was merely attempting sarcastic humor. Justin knows this and is being facetious! Hence the missing strike from my quote.

The beryllium would have to be inhaled or ingested in larger quantities, or over a period of time, to be harmful enough to measure. Much like lead. Hence, don’t chew the beryllium with lead on it.

Sorry for any literal misinterpretations.

I would like to see a spring like in figure 2, myself, such that a protected cell with button top would contact either end when using the spring inverted or right-side-up.

I will spend the time that it takes to get some answers tomorrow, provided they even answer the phone.

That's why I carefully store my solder, wire, springs, hosts and charged cells in thickly padded duffle bag for safety. Innocent

If the diameter were right, I would like the #4 version. Essentially what I am trying to have produced in a narrow profile with thick berryllium copper. Of course with my current progress it’s more like wishing to have produced.

Better current; won’t melt at very high amp (I hope). Ex: 6A at 4V
The downside is people who sell these won’t communicate.
