Dimensions of available springs and where to get them

[evert]

We have the spring dimension thread, that lists everything people have measured.
But I suddenly had the idea that a thread listning available springs and where they can be bought would be a good resource.
Remember that spring sizes changes with batches and scragging - and measurements can be approximate!

So, I'll fill in what surfaces of updated info here:


Titan Mainsprings - distributed by John Knibbs and available from many airgun shops:

Measurements by members of the Airgunbbs:
Titan #5: measured at ID:13,0 - wire: 3,0 - 33 coils
Titan #7: measured in hand at 255L x 19.8 OD x 3.02 wire x 3l/29 coils x 42 lb.f/inch
Titan #8: measured at ID:13,4 - wire:3,2 - 34 coils
Titan #10+: measured at ID:15,0 - wire:2,9 - 31 coils

Maccari/Air rifle headquarters
Maccaris selection changes over time as he adds new springs. He also sometimes makes changes/tweaks to his springs over time.
Info can be found on some springs on the website some of the springs here are measured by me.
Some of Maccaris springs have closed coils in one end to give extra piston weight.

Great idea, evert.

There will be many sources of mainspring. Many of which you know of and have used to good effect.

To help kick this off:-

Thanks!
I was thinking we could gather credible dimensions of what each supplier has, so we know where to go for what we want/need for a project.

There has been some discussion about the accuracy of measurements on some of the titan XS lists out there, are there any updated lists?

Thanks! Some of these measurements are said to be wrong, so any updates would be welcome.

Brilliant. And you are so right, evert. I guess some specifications might change a little from time to time?

The Protek Supplies site also shows the measurements of their springs.

Sorry I can't contribute much at the moment.....the Fun Prevention Officer is on the prowl.

Going to ping this onto the Mainspring Data Thread too, if that's okay, Nick?

The measurements shown for Titan 7 are incorrect --- these are the real world measurements :-

Titan 7 fits the 50 piston with enough slack for, probably, a 0.5 mm sleeve
Measured in hand at 255L x 19.8 OD x 3.02 wire x 3l/29 coils x 42 lb.f/inch.

Having the correct sizes is pretty important when chosing a spring for an older gun --- if I'd have had these measurements before my last visit to Knibbs I'd have bought one.

Specs of the Welsh Willy Spring, taken from a post on your HW95 spring thread, evert.

Try one of welsh willys new HP Dagda springs, might well be close to your needs , may not be on his site yet ??? but are available , you'd have to talk to him, didn't realise you were in Oslo

Dimensions are as follows
34.5 coils
280 mm length
Wire Gauge 3.00 mm
O/D 19.60 +/- mm
I/D 13.6 mm
