RETIRED
Sorry but
I retired from the Airgun Tuning business all together about
two years ago. I no longer have any parts or machine tools
for tuning. I had retired 3 times in the past and it didn’t
last long so this time I sold the tools to make sure that I
stayed retired…lol

Why a Springer airgun tune?
It is important to understand that tuning a gun does not
necessarily increase the fps (and usually doesn't) unless
there are issues such as a broken or fatigued spring, a
damaged seal, or a rough chamber wall or a combination of
those conditions and others. The logic in a tune is to
extract the efficiency of the gun, to make it a smoother,
more accurate, with more consistency and efficient with less
spring vibration and twang and reduced recoil with an
improved smoother and lighter trigger pull making it a more
pleasurable shooting gun.
What a tune does and why it's important, whether I do it or
someone else does it.
First: I have yet to see any lower end guns, especially in
the Chinese rifle’s using synthetic seals not having at
least some damage, often times minor, and some with sever
damage, which the buyer will never know even while shooting
it unless it is extremely bad or he breaks a spring or he
has a Chrony and can see the power loss. Secondly: again,
especially in the Chinese clones, the vibration or spring
twang and torque caused by poor or incorrect lubrication,
and poor quality control, rough components, and poor spring
design and construction causes’ inconsistency, loss of power
and inaccuracy. Thirdly: either little or no lubrication, or
incorrect lubrication of other critical internal parts.
Fourth: smoother, softer, and depending on the gun, shorter
more predictable trigger pull, and finally, resolves most
rough cocking conditions.
Spring twang or vibration and cocking roughness.

First there is the roughly finished metal on the interior
parts caused by poor machining and stamping. Two dynamic
things that happen when you pull the Springer trigger. First
there is double recoil. When the seer releases the spring,
the gun starts to recoil to the rear. Then when the piston
hits the bottom of the cylinder, it drives the gun forward.
The second thing is that as the gun is cocked, the spring
expands and at the same time twists slowly until the piston
is latched by the sear. It may also cant or bend the spring
during this process. When fired, the reverse happens, but in
a fraction of a second. The twisting during decompression
causes the rifle to twist in the opposite direction of the
twist of the spring. For every action, there is an opposite
reaction of course. A tune helps reduce much of this violent
reaction.
Tuning, if done correctly and depending on what kind of
tune, reduces spring vibration or twang, increases power,
and makes for a smoother cocking operation. In addition,
there will also be a softer more predictable trigger pull if
a trigger tune is done or the GRT-III trigger is installed
(a far superior trigger with a lot lighter trigger pull).
Another important result
is far less recoil, less twist (torque), more consistent,
and will be more accurate shot after shot requiring very
little service (lubing and maintenance) for the life of the
gun.
Keep in mind though, springs do break on occasion and seals
do go bad and are considered a where and tear item. I use
nothing but the best seals and springs available for the
particular gun. The best $30 for basic parts you'll ever
spend on a Springer. If special kits are used, such as a
TurboTune kit, or the GRT-III is installed, the cost will be
a little more.
About the proper internal lubrication.
Proper lubing is of the utmost importance. How it is lubed,
at what points it is lubed and what lube is used on those
points make a tremendous difference how your gun behaves,
its accuracy, it’s consistency, seal and spring life, and
it’s longevity. It’s important to know that there are
several lubes used in airguns for different purposes in
different locations and they all play different roles.

So many things are resolved by a good tune and these
principles apply to all airguns. You just can't beat the
money spent for a tune, especially if it's tuned properly.
But please keep in mind, no two guns are the same coming off
the line, or tuned by the same tuner, have the same power
and consistency. Secondly, power should not be the primary
concern, although important. If it's tuned and comes out
extra strong, that’s fine as long as it fires smooth and is
consistent. If not, it should be “de-tuned” a little.
