I’ve been a little absent looks like everything worked out!

So if I understand it’s 30 cents per small spring + 5% for paypal for US orders?
If so bump my order up to 16 springs and inbox me when you have the time. Thumbs Up

I wonder if it’s too late to ask for 10 of these springs? I’m about to take the leap into modding my first flashlight! Thanks so much.

All 2000 big springs have been sold. There are still some small springs available.

My Convoy L6 thread with XHP70.2, Texas Avenger FET driver, Narsil v1.2 ramping firmware (old), lighted side switch and cut down SMO reflector. Lots of amp draws on stock driver as well.

Probably after I sell both the 1st batch big and small springs.

I will also tweak the design for slightly higher current using slightly thicker wire at 1,1mm, and a better coating, probably gold if we can afford it.

The main difference would that I would make a 5000pcs batch instead of a 2000pcs batch since I have a battery holder project in the works that could be amazing!

BlueSwordM, Would it be possible to order a batch of springs like this that will fit the switch tower of a maglite?

I would pay for the 2k batch. The dimensions of the spring are

L: 32.76mm
OD: 8.15mm
ID: 6.45
Thickness: 0.83mm

The most critical dimension there is the OD since there are metal caps that go over each end we cant go larger. Any of the others could be adjusted a bit as needed.

Hey Matt? Will it help to gain electrical conductivity in replacing that spring when the ground is still the long steel contact slider? It only makes surface contact on the outside of that pillar, gotta be losing a lot there. I know it is as I just built up a triple in a chopped 1D and am not impressed with the result, even bypassing that center spring, pretty sure if I rig a bypass around that ground it’ll do a LOT better…

Yes, bypassing that little strip would also help. Part of the reason I want to get the springs is also because under 8 amp continuous load sometimes the factory ones loose their spring. The internal switch contacts seem to hold up better than it. In the fully assembled lights I sell I always wire bypass it but that gets tiresome quick Smile

@ DB Custom & vestureofblood……. Have either of you received your springs yet??

TA’s were delivered to him 8 days ago. I have nothing yet & wondered if it was just me.

All 4 of our springs were shipped at the same time and although a few hundred miles apart for some of us, we are all in the same area of the USA.

Just curious & hoping my springs were not eaten by a wild hog… Big SmileBig Smile

I installed one of these springs in an SC26 the other day but since it uses a boost driver all I can really report is that it solders fine and held up to the moderate power fine.

Have not had time to mess with the MT09R yet.

It is strange indeed, I was really surprised when mine showed up so fast, I did not expect them until about next week to be honest.

Mine are not here yet. Not worried at this point though. For me to mail a letter to a town 30 miles away, often that letter goes clear to St Louis. (passing thought that town on the way) and then back.

Alright gentlemen, thank you for the info. I just wanted to make sure I was not odd man out. Wink

Yours does indeed seem very “odd” ‘DB’ since you are only 2 hours from TA…. VOB & mine are slightly less “odd”.

Maybe USPS reverted to Pony Express for ours. Big SmileBig SmileBig Smile

@AFS, I saw your request for your springs. I’ll try to do a drawing for it Sunday.

Also, I really hope you all receive your springs in due time, especially since TA already received them.

I also took all pictures of the packages, and the shipping labels correspond perfectly with the addresses you all gave me.

Not doubting you at all BSM. Smile . It is just weird that TA got his over a week ago & the rest of us have nothing. Just goes to show the inconsistencies that can occur with shipping & receiving….. With no apparent rhyme or reason considering they were apparently all shipped at the same time on the same day. Big Smile

Look forward to the drawing. +1 for what Teacher said. I don’t think anyone is doubting you sent them etc. The fact that you still show up to the thread is evidence enough for me Smile

For me, things usually go to Dallas TX and then straight by here to Austin, TX and back to me. I’m about in the middle between Austin and Dallas (actually about a third of the way, closer to Austin…60 miles to Aus and 120 to D/FW) but the big trucks carry things between hubs then smaller trucks carry things to the towns. So it would be fairly normal for there to be a day or two difference once something hit’s Dallas and then to get here. A week? That’s odd. But then, this is the USPS we’re talking about and I’ve seen things ship to Florida then back to Dallas then to Austin and to me, when Florida was 1000 miles out of the line. Go figure.

Edit: To clarify on that, I’ve seen a package go from Illinois to Dallas, then to Florida, then back to Dallas, then to Austin and then to me. A machine read the zip code wrong. Happens all the time. With all the Automated stuff these days a smudge or bit of dirt and zoom! Off to the races…

Yeah. I know you guys are probably going to get your springs, hopefully.

BTW, I’m finally going to get a DPS5015 buck power supply so I can finally test the spring at higher currents, as my current power supply is limited to 6A before the voltage collapses down from 4V to almost nothing.

Also, I finally came back from my trip. I went to the Czech Republic as a stop, then directly to Turkey, back to Czech Republic, and then to Germany in Berlin, and then back to Prague in the Czech Republic and back to Canada.

It was a truly wild ride.

@DBCustom, wut? How could they actually miss a packet by that huge distance?

Interesting journey choices, certainly not mainstream. (kind of like Dale’s packages Smile )

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)

Ok guys.

I just realized 2 things.

1. I completely forgot about Mr.Scott’s spring order, and by adding TomE, AEDe, and the TheOnlyDocc to the order list, there are only 25 big springs left for Mr Scott. We are at literally 1975 springs, which is the reason why I wanted to stop the group buy, so I could get myself 100 springs, but I split up my order by half so TomE, and TheOnlyDocc, along with AEDe could get them. So MrScott will only be able to get 25 big springs.

2. What kind of spring would your prefer as a smaller spring?
- One like the Fasttech Carobronze spring, only with thicker wire, a wider top, and less coils so there can be more spring movement while not sacrificing too much mechanical strength, while still being way better mechanically than the Carobronze spring, according to my calculations.
- One like an almost symmetrical driver spring.

The 1st choice would allow for a dual spring amount, and would allow for a full 20-23A of current to pass through a single entry point, rather than 13-15A like my current spring.
You could use it as a smaller spring, but you would have to flip the top and the bottom to allow it to fit single side driver boards.

The 2nd choice would allow for universal compatibility, but making it much harder to incorporate as a dual spring.

What do you think?

Also, the list has been updated.

Edit: The first point is null now.

If needed I can give up some of my springs

I totally want option #1 for the small springs so I can use them as dual springs. In fact go ahead and up my small spring order to 100 total springs please if this is the case so I can use them all as double springs.

The Fasttech springs sag real quick.

My current and or voltage measurements are only relevent to anything that I measure.

Wouldn’t this mean that TheOnlyDocc, the last person, has asked for springs that are not available?

Yeaaah. However, I was willing to take off some of my springs so everybody could have them at least.

This is why I wanted to stop at 1950 springs: in case there are problems, there would still be springs that could be shipped.

Edit: Maybe I should have changed the title when I closed the GB. My fault. Facepalm

Also, there is a good reason for why the Fasttech Carobronze spring sags electrically and mechanically:
it has a way too wide top diameter, thinner wire, and probably uses a lower electrical grade phosphor bronze at 15% IACS vs the C54400 19% IACS of the djozz springs. It also has a bit too many coils. Removing one while widening the top diameter would help a bit in terms of mechanical strength.

Edit 2: I’m way too soft. I should have refused for his spring demand.

@shirnask and skinny-tie, I will put some extra things in your order so you will still have some good things in your package. Brass buttons and perhaps, some small extras Thumbs Up

@Mr.Scott, I’m really sorry for forgetting about your order. I’ve corrected the error now.

Edit 3: TheOnlyDocc, out of kindness and patience, will wait for the next batch. So you can get your springs back.
