Model V8 Engine

Part 1

Internal Components of Syringes

At the beginning of our journey, Nicole and I thought we could make the project entirely out of wood, metal, and other stock materials. The first thing we did was follow the DIY videos instructions and cut up the syringes and some other components into their desired shapes.

Sketching

Nicole and I sketch a shape for how the peanut shaped connectors should be cut into.

Cutting

Nicole and I cut the pieces of the two joints of the inside of the syringes and I cut lexan pieces of the top bar of the V8 Engine.

External Components of Syringes

Cutting and Gluing

Nicole and I cut the encasings of the syringes into cylinders, sand them down with a belt sander, and hot glue them together.

Using Epoxy

The hot glue did not hold well and the cylinders kept breaking apart, so we decided to epoxy them together instead.

Part 2

Somewhere in between cutting the peanut shapes and other internal syringe components, we realized we needed to 3D print them to work efficiently. While Nicole made the 3D printed parts, I made multiple rotary axles.

CAD-ing and Printing

Nicole went to work at the internal components of the syringes while I CAD-ed the peanuts. Below is a picture of the both of us getting the parts from the innovation lab.

Our First Syringe Assembly!

After we got the 3D printed parts, we attached the internal components with vex bolts and lock nuts. Then we put the added the caps and put the whole assembly together.

Filing

After testing the movement of the syringe assembly, we realized the peanuts were too wide. Therefore, we filed the sides down.

Part 3

After assembling the new syringe components, we realized the friction between the rubber and the cylindrical encasing would put too much strain on the component and break the Model Engine. While I lubricated the encasings, Nicole replaced the rubber caps with hot glue.

Loosening the Attachment

Since it was really hard to move the internal and external parts of the syringes, we sprayed silicone spray onto the insides of the encasing and replaced the rubber caps with hot glue.

Part 4

For the base platform of the engine, we cut up three-quarters inch wood and hot glued the pieces together. After that, I tried multiple ways of making the rotating axle.

Cutting and Sanding

To the right, Nicole is seen using the disk sander to make a wider acute angle for the syringe assembly to connect to and smooth out the cut.

Finding the Right Axle

At first, Nicole suggested using paper clips to make the rotating axle. After making a prototype, we realized the paper clips were too flimsy. Then, I tried to CAD and 3D print an axle, but that also turned out to be too flimsy. After that, I went to Tribeca Hardware and bought multiple different rods--some hollow, some aluminum, some bronze, some copper. I bent and tested all of them.

A Semi-Success!

After numerous different failed trials, I bend a hollow bronze rod that successfully spun on the base. However, the notches were a little too large in width and did not hold the syringe assembly well.

Part 5

Although we forgot to take pictures of this part, we used the reamer, a deburr, and a drill with a small bit to widen the holes of the 3D printed parts of the top of the V8 engine.

Here are some pictures of the CAD we made for the 3D printed parts.
