Stroke lengths, TP sizes and SCR for various springers...

[TonyL]

BRILLIANT IDEA BRUCE!

And, you're right, why not extend this to as many different rifles as possible, as a quick reference guide.

Maybe even an excellent idea for a sticky, chaps?

It's really weird brucy boy as this is exactly what has been going on in my head too the past few nights!

Strange!

I would also love to have a list of this info, to suss a few things out that I've been wanting to experiment with, and generally get my head around.

( why am I never happy to just shoot my bloody guns!)

Perhaps you could also include things like piston weight, std spring dia., gauge and coils?

Piston weight would be a nice idea!

look here for spring details:

If people add the info we need to this thread I'll happily amend the first post so people can find what they need with out trailing through the thread.

Hi Bruce

Some more numbers for you

Wehrauch HW 35 leather seal --------------- transfer port = 4mm ID X 26mm ---- Cylinder = 30mm ID X 65mm stroke

Weihrauch HW35 synthetic seal ------------- transfer port = 2.8mm ID X 26mm -- Cylinder = 30mm ID X 65mm stroke

^^^^^^^^^^^^^^^^^^
These are not carved in stone


Weihrauch HW35 synthetic conversion kit ---- transfer port = 4mm ID X 26mm ---- Cylinder = 30mm X 62mm stroke

Weihrauch HW35LGV ------------------------ transfer port = 4mm ID X 6mm ----- Cylinder = 25mm X 71mm stroke





All the best Mick

Many thanks Mick! Great to have your modded 35 in there too

Finally worked out how to add tables in HTML so will do the sums for SCR ASAP.

Have amended the threads title so we can include AA, LGV etc.... If we can get this going it'll be a cracking point of reference.

If anyone thinks of another column, let me know now as its a PITA to add later

[brucegill]

One I'm very interested in is the 99s!

Also the LGV, TX etc...

[nat1]

Nice idea,
as well as standard figures listed for each model, do people on here have "optimized" figures for say 11.3ftlb running sweetly that could be added along side or is there no such thing as optimum!!!!!

Atb,Woody.

Hi Brian

SCR is the Static Compression Ratio of a springer action, this is the swept volume of the cylinder divided by the volume of the transfer port, normally expressed as XXX/1.
