Artillery & Wolff springs
 

Ok, so my artillery shooter is almost ready for the range. I've the Wolff Luger calibration pack in one hand, (band aids & iodine in the other), any suggestions as to which spring weight to start with ?

I'll be using the WalMart Winchester 9mm.

I must confess I don't want to change the springs out more than I have too, having read through Ted's excellent tutorial. Images of blood and bent metal flash before my eyes each time I contemplate the task.

My thoughts so far are.. the extra weight spring may be to much, based on the idea that the artillery upper weighs more than the standard so will not travel quite as fast, (although it will still have the same momentum... hum).

The standard is a tempting starting point.

Has anyone been down the same path and could recount their experiences ?

Many thanks, Stu

Wolf Springs in Lange P-08
 

Hi:

If you lived near me, I'd show you how to exchange those springs in no more than just a few minutes. With a small fixture I fabricated myself, I've taken all of the blood, sweat, toil and tears out of the process.

Unless you are going to be using hot ammo, start with the lightest spring in the pack.

My LP-08, a 1916 DWM in almost new condition, shoots relatively hot ammo with its original 90 year old spring. That longer 300mm barrel is really quite heavy and takes quite a bit more zip to recoil adequately than the standard loads I've developed for my 100mm barrel Lugers develop.

For me, the Wolff Springs are just too darned long!!! What this is doing to the spring prelaod, I can only imagine.

I hope your LP-08 has fully adjustable sights, as they will be necessary to fine tune the point of aim for the specific ammo you are using.

Seiger, could you post some photos of your fixture?

Or are you in the process of applying for a patent? (:-)

Thanks Sieger.

It does have fine tune front & rear, (front inoperable though, need a screw).

I'm planning on banging an appropriate sized nail into the workbench and cutting the head off so I can slide the spring keeper down onto it.

Hopefully this will keep things steady and allow two hands on the frame !

Sieger,

can you post pics of your fixture or e-mail them to me.
I made a spring compresser from an old hose clamp pliers, but would like to tweek it a little.

thanks,

Jim

Interesting,

I placed a pair of pliers on the bench, used it as a support for a repro loading tool. Placed the spring upright above the loading tool (diameter of tool hole and spring was roughly the same, perfect). Slid a small screwdriver through the hole in the hook en pressed the hook down through the spring and the loading tool hole with two hands. Afterwards, it was just a matter of detaching the loading tool again.
