I am using flat head 1.2mm screws to bolt the plates. I have wood screws and machine screws with square nuts for the braces. It took me a while to figure out why the movable bearing plate has a thicker section. That is so it can be tapped for the rod that bolts the axle.
I tapped this section 1-72 for a scale 1" tie rod.
Here is one of the 1.2mm wood screws in place.
I bored the wheel fixture for the hubs then took an 8 degree cut on the face to clear the spokes. I used white-out to prevent any silver solder wicking down the spoke. Here is the first one ready to bolt on the other half of the fixture.
The white-out worked to block the silver solder.
I threaded more spokes for the next wheels and took photos of the thread roller taken apart to show how simple the design is. If a rod is broken while rolling simply take it apart and reasemble it on a flat plate. Try fixing a tiny cutting die.
To thread a spoke I simply put one in a drill chuck and used the roller by hand. The spokes were beveled on the lathe and it takes a bit of pushing while turning to get it started but for just a few quicker than the lathe.
I needed a way to attach the main tie rods to the frame members which are about 5mm wide so not a lot of room. I made up some special thin nuts with wings.
The front tie rod is 2-56 and I heavily modified a T nut to secure the 2-56 all thread for the center tie rod.
The rear tie rods are 1-72 and I made similar wing nuts from brass.
All this will be covered by the lolly stick deck.
Here are the rear wheels with paint.
In order to finish the steering gear, I needed the handle. It took several tries to get all the bends in the correct place. The rebuild photo series does not show the handle very well so I used the first photo in this thread for the model. Here is my final version.
To make the forged handle I used a Bell System crimping tool. The dies were removed by grinding the rivets and I made a 5/16" tool steel cube for the anvil. It is held by a 3-48 screw with washers and small plates. The forged wire is .072" in diameter and is what I make all the tiny blacksmith tools seen around the anvil stump.
Here is a photo of smashing the second handle. The first leg is easy getting the second one in the right place is the real trick.
Here is a photo of the tool there are two styles, one has two small holes and the other one has a single larger hole.
I found the two-hole one under a telephone pole when I was a kid and I have been smashing wire with them for a long time.
