@Oweban and others, I’m sorry again.
Being delayed by Canada Post for almost 3 weeks, and my own mistake of forgetting my bag full of packages for 2 weeks delayed the packages by more than a month…
I’ve just had so much work these days, and I’ll be free starting May 25th, so I’ll be up full force.
I made sure I shipped everything last Friday. I also included some extra goodies to excuse myself over my mistake.
On another note, here are the Rev 3 spring specs.
Large BeCu spring(Rev 3.0):
Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 6,25mm
Spring base diameter: 9mm
Spring thickness: 1,0mm
Spring height: 12mm
Total number of coils: 5
Plating: Copper(25 um)+ silver
Small BeCu spring(Rev 3.0):
Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 4,50mm
Spring base diameter: 5,75mm
Spring thickness: 0,8mm
Spring height: 10,5mm
Total number of coils: 5
Plating: Copper(20um) + silver
That last one actually comes from one of the R&D centers of the spring manufacturer. It’s a prototype alloy, from what I understand, having slightly less beryllium and a touch of titanium. But its conductivity crushes C17530 by a long shot while having similar mechanical properties.
If we can actually get this in our springs, that would make them the absolute best. However, the price would easily double, or even triple, according to the manufacturer. Will stay in the R&D phase for now.
So yeah, good news for absolute overkillers.
Had to erase this. Don’t want people getting hyped up over nothing.
Yes, I have confirmed FD2 tint LED’s from a manufacture I work with. Maukka and djozz both tested them in a SST-20 thread somewhere.
Although there are not that many FD2 bin LED’s available and they could be sold at any time, once gone it is highly unlikely we will find more for some time.
This manufacture has been searching for anything below the BBL for months now and this is the best they have found thus far besides a few FA3 LED’s they got their hands on and are not giving up sadly. They plan to sell them in a light at some point.
@Hoop, copper is hazardous in the form of a powder, like any metallic powder.
That’s what I was referring to, not copper itself.
I mean, it’s not beryllium levels of toxicity or any nickel salt, but it’s still dangerous, but not toxic.
Also, I would like to wonder why I actually wrote that copper oxide powder is quite reactive. Far from it.
I just meant that copper powder is reactive, like mentioned above.
It’s quite inert actually, and doesn’t react with living tissue at all.
No problem then. It’s just that in my laboratory work at college, our professors asked us to be careful when handling metallic powder, as not only would it be a mess to clean it, but they are flammable since they have extremely high surface area to air, but can also be inhaled, so we should always work under a fume hood.
I'll avoid snorting rails of copper powder going forward.
Yeah, snorting L-ascorbic acid powder feels a lot better. Seriously.

And besides, you know Texas Ace has a nice source now?
I’ve asked him, and he said that it would be possible to get quite easily from his supplier.
Are you still doing the group buy?
TA’s post confuses me, it sounds like the led’s are not available.
Sorry if it was confusing. Basically the LED’s are available but they are not “reserved”. So they can be sold to someone else at any time. Once sold it is unlikely I will find more for some time.
So, guys and gals, now that I’ve shipped all orders, and reshipped some orders that were taking too long to ship, I’m ready for the 3rd gen spring groupbuy.
Here are the springs specs.
Large BeCu spring(Rev 3.0):
Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 6,25mm
Spring base diameter: 9mm
Spring thickness: 1,0mm
Spring height: 12mm
Total number of coils: 5
Plating: Copper(25 um)+ silver
Small BeCu spring(Rev 3.0):
Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 4,25mm
Spring base diameter: 5,75mm
Spring thickness: 0,8mm
Spring height: 10,5mm
Total number of coils: 5
Plating: Copper(20um) + silver
Because of the thick copper plating to give a large boost in conductivity, the spring is again quite a bit more expensive than even the 2nd gen silver plated version.
Now, we are at 0,46$US/spring.
Express your interest below.
Will make a 3rd thread for it soon enough, along with some sweet sweet FD2 SST-20s. Will also be making budget phosphor bronze springs, probably at 0,15-0,20$US/spring along with some new additions.
I’m aiming for 0,15$US for the lower performance springs.
Here’s the data for comparison:
1st gen nickel plated springs: 0,30$US
2nd gen silver plated springs: 0,39$US
3rd gen copper(50um)+silver: Slightly higher than 0,39$US
3rd gen copper(50um)+nickel: Lower than 0,39$US, but higher than 0,30$US
3rd gen budget phosphor bronze nickel plated spring: 0,15$US
3rd gen budget phosphor bronze spring copper(50um)+nickel: 0,19$US
4th gen large BeCu C17500 copper(60um)+Silver: Between 0,40$US and 0,50$US.
5th gen Ultimate spring(in the works): ???

I’d be interested in buying some of the new batch of springs when they are available.
No problem.

Mouser has three 4000k SST-20’s listed as new.
J5402, J4401 and J4402. Are any of these any good?
402 is probably the bin you’d want; closer to BBL. 5402 has higher output.

Copper is not particularly hazardous. You can look at the MSDS to see associated hazards.

It would be generous and helpful of you if you could hyperlink your more esoteric claims to supportive data on occasion, if it isn’t too much trouble.
In relation to what, metallic powders?
No problem then. It’s just that in my laboratory work at college, our professors asked us to be careful when handling metallic powder, as not only would it be a mess to clean it, but they are flammable since they have extremely high surface area to air, but can also be inhaled, so we should always work under a fume hood.

I’m a toxicologist. This is a reliable reference for the toxicology of copper.
https://www.atsdr.cdc.gov/toxprofiles/tp132.pdf
It’s complicated, as Cu is both essential and toxic. As with all things, the dose determines the poison (Paracelsus).
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4942381/
In my view, and as Blue mentioned, just be careful in handling to reduce unnecessary exposure.
I’d like to pitch in for 10 of each type of spring if that’s possible and not too late. If it is too late, no biggie. Thanks.
I’ll avoid snorting rails of copper powder going forward.

So we should strike quick before they are sold.

Assuming prices similar to before, I’m in for 20 FD2’s.
I would be in for at least 20 FD2’s
I would also get at least 10 FD2’s as well.
I’m in for 20 SST20 FD2 if TA does the group buy instead of BSM.
