Double tap inertia weight

[KevG]

Originally did these for the RAW TM1000  for some of the competition shooters.got some good feed back so started doing them in the rapids.

Umm see you Wednesday KevG,
Will talk about getting one fitted on mine.
Ps Make sure you got all you need for Wednesday night when you come over for shoot.

Great Stuff KevG!!
So does your invention use an Anti-rattle spring on the front??
I might have to fire up the old lathe!!

yes stuart m8,just uses two standard inertia weight springs,a inner and outer,played with different material and found brass with a stainless front pip is best,if all stainless you can get a slight ping and if all brass the front will mushroom over time.

A true Genius at work!
Stainless for hardness, and Brass for density and anti-bounce qualities
Amazing!

Cheers M8,

Dont know about genius more trial and error.also awkward  making them for guns you dont have to hand as some hammers (even on same models) can be ever so slightly different  as regards to inner diameter and step depth were the weight sits.

Brilliant setup kev - cant wait to test mine out 👍👍👍

[flyfisher]

got one in my MK2 great bit of kit, shot count up, action quieter, and very consistent.

Got one in my gsx200 as it originally had two hammer springs and a nasty finished off inertia weight from standard. The smoothness and quietness of the action was so impressive I ordered another for my mk1 rapid with equally impressive results especially muzzle report more of a crisp pop than the flatulent sound it made before.

All sounds very interesting, will have to look at getting it done. Md

I havent tested mine over the chrono yet but I have fired a few pellets through the vendetta with the double tap fitted and the action feels slicker and the firing cycle does feel better with a short sharp pop - as mentioned above - I will be fitting a 500cc carbon bottle soon ..... think I will need to get a load of pellets bought !👍

Great stuff I just love seeing all these modifications 

[Longshot]

Work well in both my HMs and TMs , also the air lasts a bit longer , more efficient at pulling the hammer off the exhaust valve and when you get the hammer adjusted with a bit of trial and error you can find a sweet spot that improves down range accuracy.

Hey KevG,
Well I move this post To the tech area, where Belongs.
I just one thing to say..... You and your Rabid Fox are Evil!!
I just couldn't get this project out of my Brain!!!
So I spent some major time working on my Prototype of your Double Tap Inertia Weight!!

So first off, the springs I use are crush resistant conical springs... Never had one turn to dust
Next, yes I am using that dreaded Double Hammer Spring setup.
So that means I had to turn down the Brass double tap weight more than your version.



That small metal hat with a spring, this is the second anti-rattle spring that goes in between the steel and brass inertia weights.
Also it acts as an internal the striker for the steel inertia weight, inside the brass Inertia Weight!
Notice the Steel Inertia Weight. Rather than turning down the end of the steel weight to fit the into the spring and act like a striker.
I flip the conical spring over,  so the small end will slip over the Pip's tail inside the Hammer .
Then turned down the outer diameter of inertia weight for conical spring clearance !
This would give a little more mass for the Steel Inertia Weight.

Next up is inflating the Ul_Ti_Mate Rapid and give her a full test....
I will post updates as I go!!

nice one Stuart.here it is with internal part showing.the front spring pip is threaded to screw into brass section and is also bonded as they get some right hammer.
