Phew, the Supra just occupied another full day of my time.
I was intending on getting up at a lovely leisurely time of 10am, but that was interupted by the need to call a BMW parts dealership in the US before they closed on the Friday. What you might ask do i need from a BMW dealership?
Quite easy really, M12x98mm eccentric bolts. Which come conveniently from the arse end of a BMW E39 5-series. Now the BMW dealership locally wanted $38 per bolt set (one side) and i needed 2, and 2 for Gav, so that was getting a bit expensive. All hail BMA parts in the US, who want only $9.35 for them, and postage for 8 sets (4 for BMWTurbo) is around $30. Laughing.
And then i got a call from Repco and threw down a coffee before ducking off to pick up these:

Brand new MS123 crown rear discs. 269mm and solid rotors. Completely useless, apart from the handbrake assembly. If you remember from before i was going to run a 5mm spacer under the disc to make for a flat caliper adaptor. Well in this case there is no need, the MS123 disc will sacrifice itself to provide me a handbrake drum, and the 5mm spacer all in one.
As a double bonus these discs are on clearance at Repco for $22.50. The only reason i bought new ones.
So off i trundled to TKs to borrow the lathe:

Just a matter of machining the rotor 99% of the way thorugh, and then hit with a hammer to seperate from the hat/drum. Believe it or not that disc is currently spinning there.

After smacking it with a persuader and now im just cleaning up the sharp edge left behind.
I did the first disc in 1hr, and the second in about 20mins. Not bad i dont think for not having used a lathe in about 6 years, and the last time i used it i had a guy standing over my shoulder the entire time.

And this is what im left with, one MUCH lighter hat/drum from the MS123 Crown Royal.

And here it is sitting pretty on the hub, now im still using my MA61 rear hubs as im testing. More on the MS123 stuff later.

With the UZZ30 disc placed over the top and tightened down.

And this isnt a duplicate, thats the same clearance as before 🙂 Yay, all the theory works.
And then i set about making a caliper adaptor template. I grabbed a bit of 3mm alloy plate i had lying around and started hacking into it. After a few minutes i had this:

Now all i have to do there is clean up the bracket for duplication into either 5mm or 10mm steel plate. Havnt decided which yet.
Next on the agenda was pulling the hubs so i could fit these:

They are complete MS123 rear trailing arms. Thanks CLG for the hubs, and accessories.
Now they are reputed to be quite a pain to pull the hubs out and fit the new ones with many people opting to use a 20t press to get them apart. But the Toyota Repair and Service Manual says you can use a slide hammer to do the job. So i thought i would give it a go.

On the way back from TKs i ducked into JMS and picked up a junker S13 rear disc:
Once i had it on the bench i bolted it to a 5×114.3 disc and marked out the holes to be redrilled. With that done the drill press made pretty damn short work of the holes, and you then have what you see there, a double drilled disc, fits both on 4×114.3 and 5×114.3

A bit of 25mm SHS was then the donor for a crossbrace

And then i welded a nut for my existing slide hammer onto it.

After assembling it all on the MA61 hub
[IMG]http://gallery2.plebeians.net/d/28284-1/IMG_0561s.jpg[/IMG]
I proceded to try and slide hammer it out, to absolutely no avail, despite trying as hard as i could. So i gave up on it for the time being as it was annoying me too much.
In hind sight i can see the essential step that i missed. In that TRSM on Step5 it says you need to remove the axle flange first… duh. So ill get onto removing the axle flange tomorrow. Hopefully the hub will come out then.
I continued on by making up some jigs for the engine mounts:

And then realised that i had completely neglected to buy the 5mm plate i needed for those mounts… DOH. So that will have to be done when i can get some 5mm plate.
I then finished stripping and degreased the entire engine bay, and got it all ready for painting tomorrow. That was an entire day of work. Scary.
And just to top off today ive drawn up the rear caliper adaptor. Now to just transfer it to CAD

Numbers removed until i find out whether its the right sizing.
