Oh, Jimmy! "Mrs. Randy" could practice just about anywhere ... jobs paying big $ in really nice places like Lake Tahoe and others. She's very good at what she does ... works very hard, too.

Why, then, are we here in SE Mich?

Excuse me ... I gotta go fire up the snowblower and clear off the 8" of snow on the driveway right now so she can go to work here on New Year's day so I can afford this new diff housing.

The OP shouldn't expect a whole forum full of sycophants until it's priced right and proven to be an improvement, though.

Did you call me a Psychopants? LOL. But seriously folks... Tony's point is an exvellent one. A little prudent skepticism is probably a good thing, particulalrly considering the likely cost of such a project. However, having owned a CNC race parts business at one time myself, I think it's important to note that now that the programming is done, these can be turned out by the gobs, which will ultimately lower the cost. Steel will definitely solve the problems with this rearend, particularly if it's 4340 and heat treated.

It's done! This is the NEW STEEL DIFF HOUSING.
After paint work and reassembly, I hope to have this in my car in the next week or two.

A work of art!

The front pinion gear bearing plate is being reused. The right side (pass side) mounting ear is part of the case. And the left side (driver side) mounting ear is part of the existing ring gear bearing plate (reusing for now). After this is in my car and successful, we will start working on a new left (driver side) bearing plate and ear mount assy.

Holy crap, that thing is a work of art!

**heavymetals** · #**204** (**permalink**) 01-02-08, 10:02 PM

Very nice.

I would expect the front pinion plate to go first.

Flyboy · #**205** (**permalink**) 01-02-08, 10:05 PM

It's really beautiful ! ! !

I sooooooooooooooooooooooooo hope it works well.

Heavy,

What makes you think the pinion would go???

Washin · #**207** (**permalink**) 01-02-08, 10:20 PM

Looks like a real piece of art. I would clear coat it. It's a shame to cover that baby up with paint. How did the cutting go? Any unexpected hurdles or did everything go as planned?

It's really a dilemma on painting ideas. We are probably going to paint THIS one red to highlight what has been designed. The other choice is definately Dupont clearcoat. I think Custom will agree that hurdles never happened, and everything went exactly as he planned (and I hoped for).

Things went well!!! The only tine consuming part I had was finding the right tool for the tricky deep pockets. I would try 2 or 3 different insert geometries and depth of cuts before got the right combo. I had to make 2 fixtures to keep chatter and part deflection to a minimum. nothing out of the ordinary when your trying to cut a part that rings like a bell. the good part about it is that all the time consuming stuff is all done. programs are proved out, fixtures are done and machining process worked like a charm!!! I'm happy with the way things turned out.
