Measurement
Important Note: All measurements are in inches, unless otherwise indicated.
Approximate Measurement
This is for measurements which require some level of trigonometry that I’m ill-prepared to calculate or bolt holes dependant on the part I've purchased. This is my best guess.

Construction Note Text
Unless otherwise stated, all metal is 14 Gauge.
The basic shape of the vehicle that I have in mind. It’s very loosely based on sedans from the 1920s and 1930s, which I shamelessly admire.
The next three pictures id the general shape of the vehicle from the top, side, and front. This also shows the approximate placement of the wheels. The front of the vehicle is on the left; the rear is on the right. The drivetrain and suspension are not shown here. The top and profile views show the overall planned dimensions of the vehicle.
There will be two of each of these--one for the front, one for the rear.
The bar is 2∈ 14-gauge square tubing. It has holes drilled through it to allow the bolt tubes to go through it. The bolt tubes are to allow the springs to be bolted to the frame without compromising strength.
This is 2&by;2 14-gauge square tubing.
These endcaps are welded over each end of the central bar for support, and to keep moisture out. They are 0.25∈ thick. There will be two of them.
Yes, this looks exactly the same as the swaybar bolt tubes, but in the final construction, this should have a grease nipple.
The tube here has an inner diameter of 0.5∈, a wall of 0.25∈ and an outer diameter of 1∈.
The spring bolt tubes are welded into the holes drilled into the central bar and welded in place to reinforce the central frame. They are flush with the top and stick out 0.25∈ from the bottom.
The plates for the leaf springs are then fitted over the spring bolt tubes and welded into place The bottoms of the tube should be flush with the plates.
The tubes for the swaybars are welded to the bottom of the central bar.
End caps added.
This will hold the steering shaft down the front of the vehicle.

There will be four of these total
There will be four collars total. They are made with tube with 10.5∈ outer diameter and 0.5∈ inner diameter.
This is made from 1∈&by;1∈ 14-gauge square tubing. There are a total of four sides and two tops (two sides, one top for each fork).
The dimensions are based on the leaf springs I was able to get.
This is made from 1∈&by;2∈ 14-Gauge square tubing.
These will be made with 2∈&by;1∈ Rectangular tubing.
These will be made with 2∈&by;1∈ Rectangular tubing.
There will be four of these. They will use a 0.5∈ shoulder bolt to hold the swaybar. The shoulder will give the swaybar room to move back and forth.
The forks are held on by 0.5∈ bolts with a 90.5∈ (or thereabouts) shoulder or round bar (shown here in light gray) through the pivot collars and tubes.
I’m showing the assembly here, as they will be the same for the rear axle.
Gaps between the tops and the spring tubes are to be filled in with welding.
The steering rod’s length is not mentioned here, but will be dependant on Akerman Steering. It will be determined at time of construction by the angling of the steering arms. It is made of 0.5∈ steel rod.
The springs and shackles are parts that have been prepurchased. I am fully aware the shackles will be angled downwards, but for the sake of simplicity, they are depicted as straight in this diagram. Also for the sake of simplicity, I’m only showing one leaf spring.
Also shown are the bolts holding the shackles and leaf spring in place.
I have not calculated the precise length of the front swaybars. They are made of 1∈ round tube flattened at either end.

The swaybar studs are described in the section on the front axle.
This will be maked from 1∈&by;1∈ 16-gauge square tubing.
These will be made with 2∈&by;1∈ Rectangular tubing.
This is to house the Derraileur gear and the differential. There will be a tab welded to it to hold the shifting mechanism (currently not shown here, though.) These pieces are welded together as shown.
Swaybar studs as described in the front axle assembly.
Axle bars are welded to the derrailuer frame.
Plates are welded to the bars.

Plates are welded to the bars.
The end of the spring bolt bar is welded to the end plate. The bar is also welded to the top of the support bar.
The bolt tubes are centered on the ends of the bolt bars. The gaps are filled in by welding.
The bearing bolts are welded to the frame. The bearings that hold the actual axles can be fastened to it with nuts. The bolts are centered widthways on the rear axle bars, and are placed at the end of the same. The inner bolts are also centered on the side tubes of the derraileur frame, as shown in the diagram.
The bearings were purchased.
