Great vid, Al. Great to see your work in action; also great to see you in action (as one who has only been around for a few years). Keep that digital file; it's as good as a copyright on the technology - no lawyers required in this country.

How's that home reno going, by the way. Great to see you out in the "workshed" again.


Thanks Murray. The reno is still in progress, although going very slow these days. This gun project took over my life for the past year and a half. So not much work got done on the house since the bathroom. What's left to do would only take a month if I had the money for materials, but that heavy work is getting harder, as my arthritis advances, so its slow going. Stock making is now too difficult and painful, for the money I was making, so those of you that have one, can count yourselves fortunate "I hope".

I'll save him the trouble of saying it yet again; this is a collaboration with Watertown, and the innovation is in the valve and the trigger, not so much the levers. I mention this as it seems some are confused, most notably Leonard who posted a critique of the notion of the dual lever design being patented in his forum... pointing out that it was patented some years ago. It can be a bit challenging following this SSP project through several different threads so understandable that some are sidetracked, but the power plant is apparently the really innovative thing here. I'm dying to know about that in detail, but of course not until Joe and Watertown have done what they can with getting it sold.

Thank you for pointing that out. Without my friend Wayne "Watertown" This would have been just an idea, like so many others in my life, that never became reality. I believed it was doable and that there was a place for such a gun, and luckily so did Wayne.
Patenting this gun would be a nightmare. Currently we are using a Crosman breech and barrel, but will be building our own breech in the near future, but you are right about the pump configuration already being patented, although I think by now it might be in public domain, so royalties may no longer be required. As for the internals, I am certain the valve design is out there somewhere, but I cant find it, same with the trigger and pump head. The best I could hope for would be a design patent. I invite anyone who sees this video, to try and duplicate the power plant. I believe the standard hammer valve would work, just not as effectively as my design.

Joe- you've done an amazing job on that rifle - well done. Nice to put a face to a name- you look not a bit like your avatar - good thing. He looks like a guy I used to work with- we oft times wondered about him.
I agree this rifle needs exposure, but not until patented. I know nothing of this, but I sincerely think you should look into it.
The longer stroke would be nice- what an excellent idea for a field rat rifle - just a few (50) more fps would be nice & it would about match my HW98.

Thanks Daryl. This gun is the working prototype. Some of the parts were made several times, and some parts were reshaped and reused. Also the quality in the workmanship is not as good as what would be in a final product, because why spend extra time and money, only to toss it in the scrap pile if it doesn't work. So now that we know it works, we are first going to design and build a breech for the prototype, after which, we will build a complete finished project. So far we have acquired a steel tube 1 1/8" ID for the main tube. It'll be 15" or 16" pump stroke. So we will go from 10.6 CI atmosphere to around 16 CI. Almost half again the starting volume. We are hoping that more air at a lower pressure will give us an average velocity of 700 fps. Lower pressure should equal less pumping effort, and less strain on the whole mechanism. Right now, the mechanics are maxed out, and likely wont last long. Although, the valve should never wear out, or at least it should last for many years. Same for the pump and trigger. But the pins that hold everything together are under considerable pressure, and will fail eventually. On our next prototype, we hope to incorporate needle bearings, which should extend the life of the pivot points considerably. Unfortunately most of the next gun will be steel, so it might come in a little heavy. This gun with the bull barrel and scope, is close to 11 pounds. The scope is 20 ounces and the bull barrel feels like 2.5 pounds. With an 18" crosman barrel and the same scope, it weighed 9.2 pounds. I know we can shave a pound or more off that with different pump materials, and some streamlining.
