Do 4 in 1 buckets hold up?

Actually, the design is good, and a popular one. However, I believe the flaw lies in the selection of steel used for the pin bosses and cylinder cradle.

I would consider the steel selection as part of the design.

Nope:
1) Design - Geometry = shape, functionality, and movement to achieve the desired process.
2) Selection of material to use within design constraints to achieve reliability and functionality.

Well back when I was in engineering, we spec'd the material as well as the "shape, functionality...."

Actually mild steel would be okay....if they increased the thickness, so that's part of the "shape" too.

Well Ken, I'm 71 years old and STILL in engineering.

Actually, the design is good, and a popular one. However, I believe the flaw lies in the selection of steel used for the pin bosses and cylinder cradle. I speculate that it is the same steel used for the construction of the bucket whereas it should be a low alloy high tensile steel (70,000 to 100,000 psi). I will further speculate that subsequent repairs were also performed with steel of relatively low yield strength - mild steel, and thus propagates the myth of bad design.
Not to mention the apparent total lack of lubrication (zerk fitting missing altogether) which adds to pin stress which transfers to the pin bosses. In this case, it was the pin that failed that caused the bosses to fail. Bottom line? Responsible ownership.

I wouldn't be surprised to see someone has been backdragging stumps/debris with the clam only or using the clam to "pop" stumps.

But the math and component integrity have changed over time. Maybe it's time to let go of the sliderule too

Was cleaning out a closet recently and found my basic nuclear engineering text (circa 1977) and the handy dandy sliderule. Forgot I held on to either one of them.

Duly noted. But why stop doing something you enjoy, and your boss is happy with your work? I still have my original slipstick somewhere. It's wood.
And you of all should know that the math never changes...
Totally agree on your call: "I wouldn't be surprised to see someone has been backdragging stumps/debris with the clam only or using the clam to "pop" stumps."
The Drott 4 in 1's on the 977 Cats rarely gave any problems.

Enjoying your work does make going to work feel good.
Maybe instead of ribbing about the math changing, I should have gone in the direction of "the application of mathematical models by more recent graduates may infer that previously used examples are inferior, however upon further scrutiny an omission was made altering the model in non-favorable terms for the current application". Drop that in a memo and watch the feathers ruffle

I love it! :laughing::laughing::thumbsup: That's right up there with the Turbo Entabulator.
