Dad often commented, " A welding rod holder is a VERY dangerous weapon in some people's hands." Dad could weld, he amazed me sometimes the things he could weld together. However, his weakness was his cordless drill. Son welded up over 30 holes drilled into the hood of the #70. Can only tell looking at the inside or underside, closely!
Some people should have their tools confiscated. The 126 I had was owned by some of those people. They had cut notches out of the frame to fit a K321 or K341 and left it like that. When I got it, it had a K301 in it and someone had welded scrap steel into the frame notches. The frame had sagged and they didn’t bother to straighten the frame before welding in the scraps. It was so bad that the hood overlapped the dash by about 1-2”. I immediately fixed the frame and replaced the cotter pins in the driveshaft with spirol pins.
I have an "O" with lots of that kind of welds on it. . . .
It reminds me of the service manager talking to the design engineer years ago. "He (Field engineer) is modifying the conveyor. It involves the use of fire." (I found out later the torch was his favorite tool.)
