Has any one else had a satisfactory experience with an Ox ? They couldn't have been that bad unless they are only suited to some situations.
Yep, I've got a HW35 that I was given in 1986 that came fitted with an OX, it's presently running an O ring piston seal and 71mm stroke and is still powered by the same Ox --- the gun can be seen in the October edition of Real Airgun Sport.
The Ox in this gun gets no preload on it until the trigger block is screwed in by a few threads --- I can't remember if TonyL hit the Quigley bucket with this gun or not ?
I really enjoy folks talking about garden gates and sharp corners of the spring cutting Pistons, it makes me laugh.
Don't forget that Weihrauch fitted square section springs in the early HW97 with no detriment to the gun.
All the best Mick
Another reason why I'd like to hear how peoples OX springs measure is to positively ID the springs in my spring boxes.
The square section springs I have are salvage springs from guns that came in a sorry state, so no certain ID.
Are all OX springs made from the same dimension wire?
Too many airguns!
just done a final strip, lube and rebuild, and measured up the spring.. it's actually a very soft wind, and now I'm thinking maybe it's an old HW97 square section instead ?
3.1mm square (surface area 9.6mm2, equiv to a round section 3.5mm, but the square may be stiffer - I don't know the equations)
230mm long (about 1.6" of preload)
30 coils (it's near coilbound when cocked)
20.3mm OD
With a little too much grease on the spring and guides, it's doing 10.5 FP and shoots pretty nice.. that's with just the bare action, so it should be good in a stock
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
this one is just regular steel coloured...

Yes, I put one of the regular ones straight out the packet into my .22 Gamo 3000. Changed the seals at same time.
It does 11.5 ft/lbs with only around 6fps variation.
It twangs a bit and I've been tempted to sleeve the spring, but the chrony results are so good I just decided to leave it alone.
