Teaser: new inspiration

Unread postAuthor: Brian the brain » Tue Mar 01, 2011 2:29 pm

I wonder if you guys can guess what I'm thinking..


I noticed that the front fork legs from my bobber bike, that I replaced for longer ones...had some interesting parts.. :wink:

Such as a long stroke spring...a thick-walled tough steel tube and an endplug wich threads in...and seals with an O-ring.

I intend to build something I believe no-one on this forum has ever attempted..
Although it has been discussed here a couple of times.

It will take my understanding of trigger mechanisms..and my new welding skills...most likely my lathe....and some woodwork...

And I'll flip this " old idea" around in such a way it will be more compact...offcourse..

Can you read my mind JSR? :roll:

You know what I think, and I know that you're going to do the exact opposite :D

spring piston gun?

I once tried... and lost a piece of finger. (I cant see any scars however)

You could also design it in such a way, that it diesels on purpose. (with an ideal gas-air mixture in the cylinder)

I believe you tried such a thing before? (but with a pneumatic piston)

Sorry labtec...I posted this at the same time you posted.
So I edited it...

Brabant BTW

Yep spring piston gun..
Well...I won't be able to saw off the barrel with the design I have in mind..

Because of the over under design..

Apart from the LONG stroke this twist is about the only real addition to the classic springer.
And offcourse I'll work on a diesel pump...

I'm guessing a small surface piston means higher pressure while the long stroke still provides plenty of volume.
I intend to go 9mm or so.

My HW45 is an over-under ;)

Looking forward to your take on it :D

Brabant is best wel een eindje weg voor mij, ik woon in Drenthe.

How are you going to make the trigger? If I look at the pictures, I see a very strong spring, wich will need some strong materials.

Ha,..

But wich way is the piston moving?

Mine will be travelling from the muzzle back...
This will ensure the most compact break action design.
I understand that the turn around towards the barrel isn't the best for performance...but dieseling will make up for it..
That and high flow/fairly big caliber.

The HW45 is a bit weak for my standards...
:D
I'm planning on using steel...All the way, except for the stock.

Aha..okay...so...


:D
Never the first to think of something...

Now its all about size and power then... :wink:

I won;t be doing it like that anyway..

My way will allow for a lot more leverage while compressing the spring.. :D

Since you have two springs, have you considered an opposed twin piston system? All the power, without the recoil ;) a la Whiscombe

With what I'm hoping for the recoil will come from the ammo moving... :D

I'm not interested in accuracy beyond say..15 meters..

My attention was just brought to a recoil-free hammer..

A weight inside of the piston wich will want to keep moving forward when the dieseling effect is trying to reseat the piston...resulting in more gain from the effect.

It would be absolutely awesome if you had an automatically recocking piston :D
I think power will suffer, however.

I'm looking forward to some trigger designs.

It's good to have another dutch member around

:D

I've been around for a long,long time... :D

There have been several over time.
Most noticable, besides me would be Psycix ( Rotterdam)and Jack Hogg ( ook uit Drenthe)

Now it's time to start collecting parts and narrow in on my designs.

I'll probably go with a pump type meter.Extend-fuel gets drawn in
push closed-return valve closes and fuel is pushed into the chamber.

I can make that on my lathe.

I think he meant no conventional hybrids ;) or anything else conventional for that matter.
