Re: '60 Cab project
Hi Jim,
Thanks for this wonderful thread.
Would you please supply additional info on the tumbling used for the engine pieces, i.e. type of media used, tumbling speed, etc. The shop info would be great as well. This looks so much nicer that my efforts with brushes and chemicals. I will be sending Walt at CE my case for machining and this could be nice addition to the process.

PM sent.
Moving on to the 600 grit:
and then to reassembly:
In place but not affixed:
All in but not attached; will still dress curvature and how straight the fins are:
Quite a few hours in this. Notably, the factory replacement has the late set-up (round spacers) and is quite a bit brighter than this, even though this is pretty good. We think they've gone to a bright-dip type of treatment for their aluminum, and we talked about doing this for about 30 seconds ( uh, no... ) . You won't find any of this type that have been bright-dipped unless the owner did it.
Starting the other key assemblies, though we're close to shut-down until we get the car back, everything is pretty much ready to assemble.
A little thread-chasing before we start:

Re: '60 Cab project
It doesn't really stop when everything is apart. Zero bolted to the car. So moving right along, the steering column has to go back together. Start by aligning the lower of the top pieces, then put the rubber piece back in by the bracket, and install the turn signal switch:
Then route the turn signal switch wiring harness through the right spots:
Affix the clamp that tightens the lower piece (recheck alignment):
Note that the early B columns had studs, and later columns had through-bolts:
Clean up the grease on the horn connection with thinner and steel wool, and put the top on. Good to go:
Now we wait for the primer to cure....

Re: '60 Cab project
On to the next set of subassemblies. First check the heads. We don't know how long the heads have been sitting, so we want to make sure the valve stems are lubed and check valve spring height at the least.
The little tool used to measure valve spring height:
As it turned out, Harry had set the spring height a wee bit short for a fairly stock SC/912. These are the shims that go under the springs to set the height; the thick ones go on the top of the stack:
Next up is the rocker assembly.
...and we're ready for the next steps.

Re: '60 Cab project
Busy day today. Started with cleaning the studs and installing them.
Flat side towards the case:
Mike using the stud installer, these things are pretty cool:
Cleaning up the assorted other bits we hadn't gotten to yet:
Another load from the powder coater came in today, and we got our brake drums back:
Off to the tumbler to put the finish we want on these (new splines and linings):

Re: '60 Cab project
And then we started assembling things.
Starting with thread-chasing. The powder-coaters use the little plastic plugs for nut plates, but they aren't quite long enough to cover everything, and powder-coated threads are harsh to try to screw something into. You'll end up chasing the threads at some point.
The fan/generator marriage:
Rear tray assembly:
The fan shroud assembly starts to look like a real fan shroud:
Setting the end play for the tach drive:
We also finished up the rubber seals for the engine compartment on the four panels that take the seals. Phew ! Still in line at the balancer.

Re: '60 Cab project
A little cleanup before final paint. 3/60 matching....
A little sanding to make sure they are smooth, then primer, then off they go to a real painter.

Re: '60 Cab project
Back in the saddle after the Eugene to SoCal "college is over" trip (driving the kid and his stuff back after he graduated). We got our drums back from getting tumbled:
Put the machined lip back on (brake drum refinisher and a few grades of sandpaper, then Blue Magic):
Pressing the studs back after refinishing those:
Refinished on the left vs new (but old) on the right:
And we made sure our top frame was ready to go to the interior guys, who'll fit the front bow as well:

Re: '60 Cab project
Is there a source for PRE-CUT cabriolet window seals. Unfortunately the cuts are not at right angle and my free hand efforts leave unacceptablr gaps.

Re: '60 Cab project
Cutting them a little long and then dialing the ends in on a belt sander is what worked for me. Not too aggressive on the grit. Think I used 120. Having the old ones to copy helps. Hopefully you can turn the longer ones into shorter ones and not have to buy a whole new set. J

Re: '60 Cab project
We are getting down to the last strokes before either our bits get back from the engine balancer or the car itself comes back. Don't know if that is this week or next, but soon. So what we did was arc the brake shoes to match the drums:
Then we replaced the bearing races. Here's the little tool the factory uses, it's a little spring-loaded jobbie that fits right into the spot you would have a hard time getting to:
In place for pressing it out:
Replacing the inner race on the spindle where the Turkey had put it in a vice:
So new races all around, and we're good to go when the car comes back:
Re-attaching the chicken wings and the rear bow:
And deciding what tires will go on our wheels:

Re: '60 Cab project
Jim, first off the car is now officially too nice to drive so does it come with a trailer? Second, the bearing race removal tool is great. Where did you get that? Am I the only guy that doesn't have one? Why didn't somebody tell me before? That tool is a great example of how illogical German engineers can be. Why don't they notch or undercut the hub like 99% of all designs? They have an unhealthy love for special tools.

Re: '60 Cab project
Hah, too funny. We aren't exactly declaring victory yet. Nothing on the car, we don't even have the painted shell yet. One thing about working with Larry, is that he is a true tool junkie, and I thought I was bad, but he's leading me down the path of knowing just how few really good tools I have. I don't know where he got that bearing race removal tool, but it is pretty cool. We have a down day tomorrow, I'll ask him next time I see him.

Re: '60 Cab project
You can tell we are starting to get crazed waiting for the car to return from the painter. Looking at every little thing. We started prep for the engine build, since that's likely to come back from the balancer pretty quickly.
Seals, for the head bolts and the pushrods.
And we thought we'd show the old-school process of arcing the brake shoes. They actually needed it, as they touched at the ends but not uniformly:
We got the wiring loom out and made sure the resistance of the runs and the connectors were right. We got lucky here, as the PO was an auto mechanic and really did a nice job of organizing things when he took it apart, including not making a mess of the harness; it's in great shape:
And we even took a close look at the turnbuckles that held the top on. We noticed that the reproduction shafts are aluminum, and though they have a metric thread cut on them, they are 1/4" ATF vs 6mm for the original steel ones, so we're going to take a shot at restoring the originals:
So if anyone was scratching their head at why their metric wrench wouldn't fit....now you know. The ends are a bit different as well, a slightly different finish from what we can gather, so they'll spend the weekend in the tumbler to see how that works.
