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
the bowl assembly


the goose neck



5th wheel and goose neck

some cab and sheet metal


grill

drive train HPI savage diffs anhime automation gear motors tried as a single speed great for loading but slow as **** for travel so playing with traxxas e-maxx 2 speed manual trans




running out off room
to be continued

I will be back to work on this 1 which I labeled ps433-2 soon . My 2nd trans showed up today . now to free up the lathe to make a few couplings .
as I said before I will have my vids up as soon as I get you-tube figured out . I got the watching fixed by getting a computer with a bigger processor

thats it for now
thanks for looking

Steve.. Nice going..

I could bring the D8 by to use as a push cat to save all that bending over..LOL
I always wondered how well a scraper would work for us..Lots of possibilities

What does the scraper weigh..??

[ihbuilder]

in excess of 40# , the weight is the key

ihbuilder-looking good!! what tires are you using and what size are they?

[ihbuilder]

thanks Dan , yea she's getting heavy and not done yet still got to make the ejector and may fill the tires w/bb's + elec. and hydros . thats the purpose for the 5900i + rogers so I don't have to carry it

thanks Tom , the tires are off the tamiya mammoth . 6" dia. x 2" wide they scaled out rite on

Hey Steve run up here and move my excavator with your lowboy will you? Ed

[modelman]

Thanks for the info-I gave up on the mining truck I wanted to build because I couldn't find the correct size tires.

Tom, Why don't you try to cast some tires from silicone? If you could come up with the right size you probably could sell some to others in the same situation. What dimensions are you looking for?

[sparkycuda]

I grew up with IH construction equipment and really enjoy seeing your scrapers. What truck are you considering?

I wish someone on this side of the pond would do this.

I agree the construction tire issue is not very good here ...Wonder if the rock crawler parts supplier that makes the scale rig tires could be talked into making a few different versions ..Im sure the are a few guys on here the know him personaly .
THe scrapers are looking good steve...looks like you have the drive pretty well figured out with tons of power to load ..Are you planning to add a second gear as well?
