a 1 3/8 inch diamter and 15 inch long steel pin on my excavator broke. it was a custom part, to enable a retrofitted thumb to the bucket arm. now i have to produce a replacement part. it took me almost a day to figure out which alloy steel i need. long story short, i have a piece of 42crmo4 steel coming my way. time to brush up my metal lathe "skills". a new challenge...

@whixr i grabbed an antire dead tree with the bucket and the thumb and then didn't pay attention as i was moving the excavator around an obstacle, creating a giant lever that excerted sheer force on the pin. must have been tons of load for that pin to crack. i am surprised myself. · 1 month ago
@danrl how did you manage to sheer off a 1 3/8ths" pin? · 1 month ago
