Keep asking weird questions though!

Just cast it all out of iron!
Being that these are essentially mechanical clutches with teeth like gears, they need to have a tough core. Alloy steels for these lockers are 9310 & 8620, which are then case hardened.
I'm still working toward getting my overcrowded garage into some sort of order so as to help make a prototype or two. I have all the essential machinery & tools:
horizontal & vertical bandsaws, drill press,bench lathe, horizontal/vertical mill, super spacer, tool & cutter grinder, small heat treat furnace & even a hardness tester. And surface plate for checking.
What I don't have is the working phase converter to power some of these machines. And space to do the layout work. At least not yet.

One thing to consider is that it might be easier to just fabricate locking hubs. That way we could just weld our diffs. Also, it'd mean we could run RWD if we so desired.
I've been thinking about that as well, the only thing though is the hubs, they would have to be re done, so the axel shaft/splines can spin inside it, untill you turn the lock locking them in. So I'd have to re design subaru hubs for the locking hub set up. And the rear would have to be disks, because doing drums would be a pain haha... Although, in this I could add 6 lug alike it should be haha. I'll see what I can do, I'll start some drawings

For one thing, I believe it could be designed so that the same hub would fit on both front and back wheels. Also, one could probably modify an existing locking hub or make an adapter for one to fit the subaru spline and wheel mounting surface. The only problem I foresee is that Subaru had to be weird and give our cars these bizarre knuckles with double bearings that support the whole assembly. I've often theorized about using the front hubs off of a Toyota pickup and then frankensteining the Toyota CV axle to the Subaru CV axle. That gives us our precious 6-lug hubs, and also adds the potential for rear wheel steering!

Food for thought on the locking hubs. looking over Rockford cv's online catalogs show that the Isuzu trooper and Subaru Loyale share the same outer cv race. so if you had a knuckle you could mount the Isuzu hardware to you'd be in business.
No kidding? That's a good idea! And don't Isuzu's use the same 6-lug pattern?

So do the 83-85 Nissan 720 PUs. The cv shafts on these are much thicker.
Looking into hybrid Nissan/Subaru hubs for locking fronts, Nissan stubs for rear.
Edit: Because these lockers work so well, I for one would really like to see some made for the R160 diff.
Maybe even one for the 3.90 R200 like in 83-85 Nissan 280zx diffs for offroading with IFS/IRS suspension.
Keep the good work prwa101!

What's going on with this??
Was one ever completed?
Still working at it, havnt had time in the shop to start it... This next term I'm goin to have some down time because I'm going through all the class projects like cake. Hoping to get into an actual job working in a shop soon so I can work on it more.
Still a work on progress... Ready to be done with school and start my own shop if I had the money....
I'll keep you guys posted! Learning how to case harden this term!
