- Buckner 12JR Cam Rotor. Possibly made in the years between the 1930’s to 1960’s.
It is possible that this numbering was done prior to the four digit numbering system seen in the late 30’s to the 60’s. So it’s a speculative guess that’s it’s from the 30’s. I have no way to verify this.
This sprinkler was in the same storage container with the two 1294 sprinklers as seen in the previous video.
Was full of 20 plus years of dirt, rust and other debris from storage. Cleaned this up a little from the outside and put it on stand and it seems to work!
This sprinkler was rescued from a metal recycling yard along with the 2 other Buckner 1294.
Thanks for watching!…
What an old gem! I love the sound of the cam rotors. It's too bad that no manufacturer continued with this design, it was much simpler and long lasting than the throwaway gear drive heads of today.
Thanks for the comments!
I couldn’t agree more with the sound of the cam rotors. They are a great reliable head that did last a long time.
Who knows maybe someone out there will reintroduce them one day! That would be nice!
Thanks for watching!!
Nice old Buckner cam rotor, it still works great after all these years after some cleaning.
Thank you for your comments. I am very pleasantly surprised that it still operates so nicely!
Thanks for watching!…
Really great video, Dave! Those Jr’s evolved ultimately into the 1330’s once Buckner moved to that case style and model number series. It’s amazing how well yours works right out of the bucket. I could listen to those cams click all day! Thanks for sharing!
Bill, thank you for the comments!
I was very lucky at the time to have found this Buckner when I did and rediscovered it again years later resting outside in a bucket with years of elements on top of it!
I greatly appreciate your help in identifying this Buckner! Not to mention the photo of the Buckner number 12 catalog page. That helped a great deal in identifying its history.
Yes, that cam producing that kind of sound is one of a kind and soothing to listen too!
Thanks for watching!…
Very Nice find, it works well with your pressure too! That is part of the original series of pop up Came rotors and it did become the 1282. The Buckner Cam design was truly an innovative simple approach to long range turf irrigation, more reliable with only 2 moving parts and around long before pop up impact heads; a solid reliable design that lasted over 70 years with only minor refinements.... Too bad Buckner fell into the wrong hands, or this type of drive may still exist to compete against the complex moving parts of the gear drives
Thanks for sharing
Kerry,
Thanks for the comments.
My static pressure is running about 110/115 lbs.
Thanks for clarifying that this 12JR cam rotor was before the 1282. We had thought that this could have been a possibility but could not be certain. I feel very lucky to have stumbled upon this and the 1294’s. They were in the scrap yard getting ready to go thru the shredder. I was lucky to be at the right place and time.!
The Buckner Cam Rotors were indeed a very reliable work horse for many years. It is a shame that they are no longer produced. I really enjoyed installing them and servicing them back in my working days.
Again, thanks for your comments
And for watching!!!…
Nice Buckner rotor! It runs well on your setup! And it has some impressive range! I wonder if i got a 3rd pump on my setup to run in series if i would gain much pressure to offset the cost (4-500$ for a pump and about 100ish for a new 25 foot suction hose. Id probably be sitting at around 65psi if i had to guess. Going from 40 to 53 on my smaller guns is a difference i can see. Thank you for sharing and i hope to get a cam rotor of my own someday!
Thank you for you comments.
This particular Buckner according to the data on the chart, can run 30-70 lbs of pressure, ( I have static about 110-115 lbs.) 3/16 nozzle at 7.0 to 18.0 GPM’s and 70-95 diameter coverage.
The operating of your guns to me would be on another level of calculations to find the right volumes and working pressures for the particular gun. I’m sure that different pumps put out different amounts of water.
I always enjoy watching your big guns in operation. They are very impressive!
I’m sure that one day you will find your own cam rotor. Keep an eye out!!
Thanks for watching…
Where can I find antique sprinklers like this to purchase?
As time goes on, they are getting harder to find. There are several social media websites that may be selling various types of sprinklers. Depending on what you’re looking for, some are a little easier to find than others. I have accumulated many sprinklers over a lifetime from many sources. Social media platforms, collectors, metal recycling centers, landscape irrigation companies working in that trade sometimes comes across them. Patience for the hunt is often needed. Thanks for watching and good luck in the search…
