Another Super 7

[Scale-Master]

I have been working on the master for the brake calipers. Still some refining to do, all brass.

Fits just right to the rotor…

And I’ll use these old calipers I machined from aluminum (at least ten years ago for a Camaro that ended up with drum brakes) for the mechanical parking / E-brakes.

[Scale-Master]

The caliper castings are done. The brass half master is in the foreground, the completed master with mounting flange on the left, and a cast copy on the right.
The bolt detail that will be seen through the wheel will be added as individual machined hardware, I cast them into the part on the backside since they will be mostly hidden.

Once the main calipers were set up I was able to position the parking brake calipers. I had to add material to the DeDion tube assembly to make the mounting surfaces.
The calipers are machined from aluminum, leftover parts from a previous project that I decided to use drum brakes on after I made them. I still need to make the brake pads…



A side note: Today marks the one year anniversary of the start of this project.

You are truly a scale master sir! Incredibly detailed work, a museum masterpiece.

Thank you Rick, very kind of you to say.

Made the top of the sender for the fuel gauge… I’ll make and add the mounting hardware later.

While I am waiting for the acid to cut the brass control arm brackets I decided to make the lower control arms.
Since I only need two and I didn’t think the time spent making a jig would pay off, I just went for it.

[Scale-Master]

The upper control arm and shock brackets are cut. I etched the areas the brackets will be soldered to the base as well as the bend lines in the brackets.

Here they are bent…

And all soldered together.

I also made the lower shock mounting pad/A-Arm reinforcement plates for the lower control arms.

And added the pivot/mounting points to the frame for them.

[Scale-Master]

Upper control arms are roughed out and I’m working on the spindles now. I also finished the front bushing assemblies for the lower arms.

[Scale-Master]

The spindles are fleshed out and close to being done, the left is on the left, the right is on the right…

I machined the “bearings” for the rotors, ironically exactly one year to the day of when I made the rotors. And I’m prepping the calipers which are the same basic units as the main rear calipers.

Inboard side of the left spindle assembly… The screws are just to tack it together as I build measure and adjust; hex head hardware will be fabricated and used on the final assemblies.

And mounted to the control arms…

For the first time it is up on all four wheels & tires. After only one year and 9 days of work… (But there are scores of other parts not shown here).

Man this could pass as a 1:1

[Scale-Master]

The (working) steering rack assembly is done, the last pieces being the tie rod parts. The tie rod ends are adjustable so it can be aligned once it is finally assembled.

The tie rod ends are just pinned into the spindles; the final assembly will have proper fittings there. (Those are red bread ties holding the A-arms together…)

After I had the wheels on the chassis I learned I needed more travel in the shocks to attain the proper ride height, which meant I needed to make longer springs. I used piano wire instead of soft beading wire this time. The beading wire is easy to work with, but has no memory and is too weak for this application. I went through about 12 feet of piano wire before I figured out how to get the windings even and the right diameter to fit over the shock. It snaps on both ends of the shock now and ties them together.

Then I went on to making the front shocks. This time I dealt with the spring before making the shock, it’s much easier to size the shock body to fit the spring than the other way around.

Fantastic work, a true Model Engineering masterpiece.

Time to make the nose… I started by building the areas that will mount the nose to the frame and hood out of sheet styrene and brass. Much of this part will be cut away and discarded later.

It is reinforced in part of the area that will be removed to make cutting it out easier. Final shaping of where the nose meets the hood will be done after the nose is built.

The main/front section is growing towards the mounting points; right now it is just sheet styrene and CA.
