Yeah, it’s more of a problem with the smaller spring compared to the larger one, because the wire thickness/spring diameter ratio is lower than the big spring, meaning more room for deformation.
Therefore, it will deform it more compared to the large spring in terms of %.
The small springs I've used in a coupe of lights are pretty stiff, stiffer than most stock springs. Maybe good for some mods, and for others may make it harder to thread on a tailcap - I'm having some of that trouble on a couple mods. Was debating cutting the spring down, but getting it all flat may be a challenge for me. Shame because I've decided against using them in some lights. I'd assume if I try cutting then grinding flat, I'd be taking off a fair amount of the conductive coating, or is the full spring conductive to the core?
I have cut several of the smaller springs to make more room also, mainly in the SWM V11R. I cut the top as blue did.
Its not easy once cut to get a neat looking top but its very doable.
I usually bend the cut end down slightly and file the tip of the cut to get rid of any sharp edges.
Then squeeze the top loop slightly smaller than the next loop down. Works great, no complaints.
@DavidEF, I’m currently in the middle of a bind with another spring order, so won’t really be able to order the springs for our GB until next week.
Even then, I’m going to need the funds necessary to buy these springs. I’m currently doing a lot of important purchases(new university stuff, paying for the next trimester), so I’m being very careful with my primary funds.
I’m going to fully buy the springs with my hobby funds, and since I’m buying both of the large and small springs at once to save on shipping, it’s going to be a doozy in terms of costs.

Thanks for the update! Don’t stretch yourself too thin. I’m sure a lot of us would be okay paying in advance if need be. I’m not in a rush though, so do what you need to do.

Since I already have experience and trust in the manufacturer, getting the springs manufactured should be simple and easy, not nerve wracking like the 1st time.
So, do some people here want to get their SST-20s 3500k early?
You’ll have to pay shipping of course(5$US), but since the SST-20s 3500k are in stock at Mouser now, I’ll be quick to order, and see if the tint bin they have actually looks good(should be, as it is under the BBL line by far).
This will be a sort of “beta testing”. If the LEDs aren’t good, I will sell them at cost.
If we can get the requested 170pcs, not only will free shipping be available, but the price per LED will drop to 1,50$US each at least, so good deal for a smaller batch still. It’s probably going to be a lower price.
So, who wants in and pay in advance so we can order them as quickly as possible?
Edit:Oh sorry I didn’t screenshot the latest Excel file. It is getting a bit big though
Edit 2: LEDs are supposed to be under the BBL by far, so should not be a problem.
Unless my eyes deceive me I’m still only on the list for 30lg/20sm.
I really want to make sure I get those extra 10 small, from reading over the last GB thread I think I’ll have more use for the smalls. To confirm I would like an even 30pcs of each size please sir.

Just cut the spring down. I’ve done it myself, and it does nothing to conductivity even if not flat.
DO NOT GRIND THEM DOWN. The worry is not conductivity, but BERYLLIUM COPPER DUST.
In any circumstance, do not grind them down. Beryllium Copper dust from grinding is dangerous.
One thing you can do to make them less stiff is just to compress it manually. It will plastically deform, and will make it permanently smaller.

Do you cut the top or bottom? Bottom makes it harder to get flat/even? Top would tend to scratch the batts?
Not even sanding? I'm old anyways, 20-30 year effects don't matter to me...
Cut to the top. Nickel is softer than steel, so unlike uncoated steel springs, it will not scratch the steel casing of the batteries.
