A New Method for Increasing the Efficiency of a PCP - the SSG

[rsterne]

Way to go, Travis !!!

Mines being listed as THe Sterne SSG. credit where credit is due and Steves a little late I have them in stock LOL

I didn't see them on the webpage.  How much are you selling them for?

[oldpro]

Ill have pics ,prices etc. up today sometime,  price will be $95 as a drop in unit ready to fly with two springs and instructions plus my personal line for help tuning etc. I will give $20 credit back if you send back your stock parts. (hammer, spring guide, rear cap). You can call now and order if you cant wait till pics and payment info is up.

Has anyone heard of an SSG being tested on a Bulldog?  Could one be fitted onto a Bulldog? 

[oldpro]

 Ive tuned a dozen or more bull dogs and they have very light hammers and very heavy springs and get almost no hammer bounce plus with limited shot count it all spells not worth the effort or NWTE as we say here at WAR.

Well done! Glad to see you folks can make this happen. I will bet heavily there are no null results where this device for some reason fails to perform...or makes the cocking stroke crunchy, or...heh-heh-heh

Now do please don't let it get in the way of prepping my Wasp Major...
cheers,

Bob is this the one you seen on the Yellow?  Do you see all the flaws and problems I do!!!!   http://www.network54.com/Forum/79574/message/1454028263/DIY+Marauder+Rifle+%28both+generations%29+FreeFlight+Hammer+Debounce+Kit+-+%2430.45+shipped

Yeah, I see a few things I'm not keen on.... undersized guide allowing the spring to kink.... the nylon part may be able to get out of line with the top end of the guide.... no brake shown for the gap adjusting sleeve.... I assume all you get are the 5 numbered parts and a drawing of how to assemble it with your hammer and spring....

Darn Capitalists !! ..... teach a man to fish and you never ever get asked to go fishing again.

[oldpro]

 And you have to take gun apart to make spring changes. Spring is too big in bore and riding on hammer wall etc etc. You get what you pay fore. I never post anything on the yellow because the whole site is so hard to follow so I just dont. Id like to show people who think there getting a Rstern SSG how its suppose to be done. THE WRIGHT WAY. Someone post this thread there before people waste their $30

[rsterne]

Another issue is that by using the stock MRod spring, the gun will end up being harder to cock.... so that advantage of a properly designed and set up SSG will have disappeared.... I just hope that in the rush to make a buck it doesn't give the concept a bad reputation.... That could easily happen if problems arise, not saying that they will.... Interestingly, this is the first time I have come up with a marketable idea, published it in the public realm, and had it commercialized, without being asked permission first, like Travis did.... All those interested in my Bob's Boattails, the Millennium Pumper, and a few other things I came up with, have at least asked if I objected to them being produced for sale.... They all, of course, received immediate permission without compensation.... because that was always my intention.... but they did ask.... My only requirement has always been only recognition for the concept or design, as the case may be....

Seems inevitable that in any such explosion of interest in a new mod there will be successes and failures and everything in between, largely among experimenters (myself included) but of course among commercial efforts as well. The one Steve in NC is marketing so cheaply looks like a first or second attempt, a bit cobbled together and too fussy, subject to further experimentation. The massive gap between guide rod and spring does seem a bit absurd... why not just use a bigger rod, or use a filler piece like some delrin which would double as a lower friction guide? But people will buy what appeals to them, make their mistakes. There will always be those who insist on buying the cheapest possible version of anything. It's their money. I don't think it'll have much of an effect on the SSG in terms of impact on hobbyists generally. It's a heck of an innovation and this mega-thread among others will no doubt perpetuate the properly constructed versions widely, with echoes carrying on for years around many international forums.

 People would be far better off making there own then putting that contraption in their gun, there is enough info here to do so. Shameful really.

[FuzzyGrub]

Isn't competition great!     Looks to have a few areas that can be easily improved.   I'm sure we will see many of these initial designs evolve over the next year.   Everyone benefits. 

Bob made his remarkable work "open source", just like all the technical knowledge he has shared here over the years.  IMHO, those making them for profit should be "paying it forward" to keep that spirit alive.   Donations to GTA is the first thing that popped in my head.  ie make sure that others ideas can be shared in the future.  Just my thoughts.   

[oldpro]

 Couldnt agree more. You have too give too receive. My problem with his model isnt the competition its the fact people are going to buy it and have problems and not live up to what Bob had intended then it will get a bad rap and make it hard for people like myself who work hard at doing it right to make a few dollars. Then the people who Im building them for(people who want a drop in device thats trouble free, or the guy who simply doesnt have time to source parts and experiment) wont get to take advantage of a fantastic device.

[FuzzyGrub]

It will take much more than one bad implementation to kill this idea.    Maybe it is a good thing he didn't use Bob's name on it.   

IMO: The "real" crime will be when some mfg start using it.  Very unlikely that there will be any "pay it forward" from them. 

[oldpro]

 I offered to pay Bob he turned me down, Bob is a good man thats for sure and thats why I asked him before I even attempted to build one. I may use it in the Flex if it pans out but im not sure yet if it would help it already has a similar set up on board. Fuzzy if he sells enough of them it will put a black eye on the SSG I still have to explain to people to this day our NBH isnt the same thing as the AOA device.

Yep, Bob is a real altruist within the airgun community with out a doubt.

I have to be somewhat glad flattered, in that Steve has used my concept for his design.  However, he has made a couple of modifications by using a "Chicago Nut" type of striker instead of a 1/4--28 threaded rod.   His design allows for adjustment without changing the hammer starting point on cocking, thus giving the full cocking distance to compress the spring. 

However, I agree with Bob and Old Pro, that there needs to be a better fitting spring guide.  This may be something that he omitted in his drawing but is incorporated in the final product.  That remains to be seen.

On another note, I found that a 25-20 cartridge case fits the .25 Armada OEM spring quite well.  I found that the .177 Gen 1 Marauder spring is too light on full travel.  I have pre-compressed  it  more with some spacers, but that requires more of a gap to allow it to cock (without modifying the end cap to allow for a shorter screw).

I'm working on a system to use the larger wire .25 Armada spring.  The .25--20 case seems to be a good guide for this.  I'll see how it works before posting the details.

[oldpro]

 David have you actually ever built and tested one because if this is your design you should completely rethink it. Im not trying to be mean but it has so many flaws. I made 10 different models then 5 different renditions of final model. Nothing beats actual builds and crono time and that goes with any devise or experiment.
