Goldstar Spring starting point pretty please.

[gizwaz]

The two Goldstars we've seen have original springs i) 253 x 20.7 x 3.25 x 33.5 coil x 36 lb/inch rate plus spacers x 8 mm Pre load 23 mm
ii) 260 x 20.7 x 3.25 x 34 coil x 36 lb/inch rate plus one spacer 6 mm 11 fpe with Exacts 13.5 gn
Can you say which Titan you use please?
The Titan 1 is 280 mm and 38 lb/inch so would be too much methinks. Removing coils will increase its rate but may be effective around 260 mm.

It’s a Titan 1 which is they’re recommended “generic” BSA fitment.

As you say the Titan is 280mm, 29 coils ( if I counted correctly )

The current removed spring, which I’m assuming is a standard original, is 250mm at present and 31 coils. Got a slight lean to it and coils are unevenly spaced so deff’ due replacing.

With the original spring she was shooting at 9.3 or thereabouts. I have replaced the probe seal in the barrel as that was well worn and quite hard so don’t think that would have been doing its job properly, but can’t imagine that alone would be responsible for too much power loss, or could it??

No mention of spacers. I would say with around 10 mm the original spring will give adequate energy. The factory used synthetic buffer washers, from redundant models, to trim pre load/ME.
Defective probe seals will lose energy but easy to test.

thanks for all the info so far guys, really appreciate it even if some of it shot straight above my head, lol.

Now it could get interesting, there are some spacers/buffers/weights between piston head and spring.
I assumed they are the designed fitment/amount but now thinking about it maybe not. Every days a school day eh.



I guess that’s another whole can of worms now, as in what effect will less have if I were to remove them and use the titan, as that would bring available spring space up to what would be required to accommodate it without cutting.

It’s looking more and more like I’m just gonna have to suck it up and try and make more bench time to experiment and learn in the process…….

I'd get that lot out of the piston, as you shouldn't need them, and will make the piston too heavy.

For what it's worth they're normally the synthetic buffer washers used with the earlier BSA O ring seal setupo so weight is quite low.
My theory is they were using up stock springs and needed suitable spacers which again they had in redundant abundance.
Seen ones and twos but never seen four before.
Spring space may be 238 mm so 280 Titan at 38/40 lb/inch still seems a lot to me.

I wonder if it was someone's attempt at twang suppression in a previous fettle?

Get 'em gone!

Again thanks for the comments guys. I’m slowly learning 😂.

Will whip em out and go thru some suck it and see scenarios to work out what’s what and works best.
As for a twang reduction attempt, it didn’t work at all. When I got her she had a such a twang even zeberdee himself would have been embarrassed. Couple of thin poly card sleeves sorted that tho.
