Oilfield Pumpjack scratch build complete!

[misfitsailor]

I made my own plans, choosing details I liked from various pumpjacks. The equalizer is my of own design. It took a couple of months from start to finish. I look forward to displaying it at the shows I attend. The gearbox gives 30-1 reduction, which is fine for model steam engines or hit & miss to drive it. It is 23 inches tall and weighs 12 1/2 pounds. The walking beam was formed by brazing 2 lengths of 1.5x.5" steel C channel back to back. The ends were then milled and steel end plates brazed on. Most of the work was done on a 70 year old Logan 10" lathe, and a 40 year old Jet 8x30 knee mill. The hardhat and wrench for the roughneck I 3D printed. There is a video below of it being powered by an "Odds 'n Ends" hit & miss engine. I hope to make a wellhead for it later, complete with bridle and sucker rod. (Yes, I know it's not an engine, but is still model engineering. )

That's pretty darn nice!! Your technician is looking at that wrench like it just said a nasty word... work maybe??

You have the speed just right for a light crude. Must be a good field as light crude is getting hard to find in the lower 48.

I'd love to see your well head when you do it. I hope you'll post it here!

Thanks, 10K Pete. I think the tech is wondering if he grabbed his metric monkey wrench or his SAE monkey wrench. lol

I have seen pumpjacks run at everything from 5 rpm to 20 rpm. This one runs at about 18 rpm with that engine. I will be able to run slower when I use a steam engine to power it. I will post photos here when I have the wellhead done.

It has an expression much like this well known bird:

you must have been out to coalinga at some point in time . those are all over the place there , but they let the paint get run down now. they used to be real pretty all painted up

itowbig, yes, I have indeed been to Coalinga, CA to visit the "Iron Zoo". I recall that parts of the oil field had very noxious fumes! Here is a link to some interesting info about the Iron Zoo :

I live out there (well pretty close ) i have fond memories of these from when i was a kid. I have many pis of them and the really old wooden one , they moved it to the city edge now. the paint on them is just about gone now. I wish they would restore them .

Merry Christmas, y'all!

Here is a video of the finished project mounting on wood, powered by a Kerzel hit & miss engine.

Nice! Looks just like the one...
