2 IH 433 payscrapers (ps433-2 moves)

[ihbuilder]

I do not quite remember all of the beginning so I'll give some pics w/a narrative . I decided to try to build (what I have seen thus far) what has not been done . so far it is a great success
the scaling of pics and design and pattern making , starts with a parts book and some general knowledge of compacity range as it's difficult to acquire data for these old machines . all motor scrapers have a basic shape and size according to bowl compacity . So I figured out the comparable machine in another bran such as a cat 637 to get the general dimensions . basically using the tire size to finesse the design

the patterns

the 5th wheel

the cut plates waiting to be welded

the next few pics are of the assembly . now scrapers are heavy so are these by design the round at the goose neck is a 12000# front axle king pin
