Can't stop purchasing Experimental Gear

[JakeFury 225]

I've got three or four various springs and guide sets for my 97. 

Looking to lighten the action as well..

May buy a new cylinder and piston for tuning. 

Lucky the pubs are shut!

I know what you mean jake, I can’t stop buying fish and chips. Bleddy grand they are

Lol I been there, good fun tinkering about tho isn't it what's been your faveroute set up so far?

I've tried a number of springs in this and other rifles. TbT short stroke is good, but Nylon66 I think is a better material for rotational forces.

Short stroke with piston weight reduction is the way to go. Titan spring, ptfe sleeve. 

Don't get too excited but I have bought a whole piston and chamber for the 97 to do something radical with, and if it works were going to manufacture it as a kit.... Spoken with a lot of people whose approach involved rings, and buttons, and, tbh from an engineering perspective, I think a spring driven forward motion will yaw with rings, I've seen this in other machines, it's not totally contained thrust, as the piston is outside off the chamber when it's released.. Time to try something radical.. 11 ftlb max a spring and action that matched for that max power and has been on a diet. 

Mind you it might all fly apart and recoil like a b@stard only one way to find out. Hahaha

Nice work! I never had much luck short stroking but that was just hw break barrels (80 and 85)  Are you going to try doing delrin rings or something?

No, we may make the stuff available if we can mod the HW pistons easily and get hold of them. But the research will be "open source"...when I know it works I'll reveal as I don't want a load of broken Rifles on my hands. 

I think the delrin components and rings on the pistons are a red herring. Piston weight is key and if a standard washer can generate 18 ftlb as I've seen, then, no need to change that the rings would only be there to provide a run alignment for a smaller lighter piston. On 97 as we can see the piston is withdrawn and fired into the chamber, so any rings outside the chamber would eventually be ruined, I think the best bet is to... Well.. go light... When I know it works and doesn't break I'll show everyone how. 

I'm mightily cheesed off the the unobtanium tuners. And people knocking Sandwell, as I know Tony and how well his guns shoot is common knowledge in some circles yet people still claim he just fills them with grease. Anyway... 

Would be nice to speak to someone whose done transfer port mods. As they might be implicated by these changes... 

Short stroke may not prove to work well for us. But I think the success levels may also have something to do with piston weight and the springs ability to accelerate the piston into a smaller swept area. 

Hope that makes sense.
