Well, I tested it and it worked better than I had expected. I started on the higest governor setting and backed down until it would not misfire. We counted 605 rounds a minute. Dad said we could tinker with the rifle and perhaps go a little faster, but I am happy with it right there. The outfit I got this from does not want any photos posted until thier patent comes through. But during the calibration and set up I was able to see how this thing works. It is pretty amazing. A folding handle has an 18 position deadman clutch. When engaged, it drives a shaft with 7 lobe cam with floating lobes that activate a roller on the top of the butterfly. At the other end of the shaft is a tiny planetary gearbox driving an adjustable flyball governor. There is also a roller ramp bearing/clutch that prevents the spinning governor from continuing shaft rotation after the cranking stops. The whole thing is built with M2HB grips, frames and butterfly. The handle folds out of the way for single shot use with the butterfly. The only modification to my rifle was to drill a small hole through the radius in the trigger. A friend that has a .50 cal said it's identical to another crank unit he saw except the governor. I took this to work, (Grumman Aerospace) and the engineers got all gooey over it. The said no way could it be made for less than 15K, but I understand it will be sold for $1850.
The maker said he will introduce this thing at Knob Creek in April.

I'm new to posting on this site and I was impressed by the rapid response to my question. But I'm a little bewildered by the rest of the stuff you guys posted. Can someone bring me up to speed?

Not your fault, There is one man who patented a device that does the same thing that the one you have does, he patented it,and lays claim to be the only one who can produce such a device, and when anyone dares talk about another device other than his he has a fit! He threatens any who dare challenge his claim with Lawyers, there have been some heated discussions here in the past on this topic, What I do not understand is that he has decided to no longer produce his product for either the 30 or the 50 cal. so why protect something that you have no plans to continue to produce?
What happens in the real world is someone patents something, others look at their design and figure out how to build a simular item but it is changed enough that they do not infringe upon the original patent, it happens all the time, and it is what makes competitors creative. If the original patent holder takes their compitition to court they better have an airtight case, or else they are wasting their money on frivolous law suites.

Royalties? Maybe the patent holder wants to be paid by manufacturers for the right to use his design? Or maybe he wants to hold onto it until someone buys the design from him? There might be other reasons as well. Without knowing the individual personally or being a mindreader, I'm not able to do more than guess.

I have absolutely no dog in this fight,, I posted this elswhere and will do so here,,

My Father was a package designer back in the day,, a commercial artist that did work in NYC that maybe only two or three people could do. He came up with a dispensing design that would put out exactly the same ammount of product each and every time it was used. He got a patent on it and then tried to sell it. A salesman who worked with him tried "unsucessfuly" to sell it for him,,, amazingly, the device showed up in production and being sold on the market a couple of years later by a company that the salesman had dealings with. My Dad didn't invest his life savings in the project,, no end of the world thingy, but he did get screwed out of profits that would have been helpful in his retirement. As a consequence, I have no use for the patent office in this country,, the subtle way you can change a device and get away with it is detrimental to new ideas. I have come up with a few over the years, and have not moved on them because I feel that I might be wasting my money trying to patent them. Two of them showed up in the marketplace a few years later,,, my fault,, no balls,, no blue chips!

When some ******* can take a perfectly good product that someone put his thought and money into and go to a third world sweat shop,,, brainstorm with his buddies and come up with a minor modification,, re-produce the item and is able to bring it back into this country and sell it,,, there is something wrong with the system. Maybe thats a contributing factor to the decline of industry in this country,,, why bother.

Not saying that this is the case here,,, the whole thing touched a very sensitive nerve with me. Industry is gone in this country,, given away to cheaper manufacturing techniques,, don't think there were not some product ideas that got ripped off in the process.

Laura,

welcome to the site.

you just got caught in one guys delusional mindset that you: as VAGunner and i were in some sort of cahoots together to "set up" a big bragging session on Ryland Fleet and the ACME Gadget Division....

that was not the case, as ive never spoken to you or met you at all and had no idea who made your krank for your gun.

actually had thought that your device was made by the delusional member who claims to have the exclusive rights to make kranks/cranks/krancs/crancs for these guns.

you caused no harm and did nothing wrong. enjoy the site and dont pay any attention to that kind of stuff.

there is lots of good people here to talk to and deal with.
