BLF Interest list for Very High Current Beryllium Copper springs Pt1(ENDED)

Yeah, there are some possibilities. I ordered some LED’s for the MT09R today, if I get some time I will put it together.

So, other than TA, has anyone received their springs or not?

These still available? Can I get qty 50? Didn't sign up for them, just heard about this.

If for whatever reason you miss out on these here Tom I got enough that I can share some with you if you’d like. :wink:

I have a 50 pc order that I can split with you, 25 pcs. :beer:

I’ll also spare 25pcs for you TomE.

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.

Nothing yet, but I am expecting them to show up any day now. :slight_smile:

If the offer still stands i would be in for 20 big springs and 10 small (if shipping is not to much)

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. :+1:

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.

Is there a second batch planned anytime?

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!

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 :slight_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… :smiley: :smiley:

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.

I haven’t seen my springs yet, was thinking maybe today? I’m only a 2 hour drive from TA, seems odd that the packages are so far apart…
