Reverse Engineered Object: Rendering the Object Part 1

I have begun to construct the scissors in 3 dimensional form, starting with the screws.

Here I made the screw using spiral, and sweeping a triangular shape following the spiral. Combined with a few cylinders, the screws begin to take shape.

Adding the rounded top to the screw.

And finally adding the indent for a screwdriver head.

Almost forgot to ad a slight rounded bottom to the screw

First screw is done, aside form my difficulties in combining the shapes using the command BooleanUnion. Perhaps I will have to reconstruct the screw to do so?

Moving on to the next screw

The screw part is done, same method as the first one (also same problem combining the parts).

I am a bit unsure as how to create the texture for the piece that the screw is attached to. I will set this aside for now.

From the screws, I moved on to trying to construct the blade of the scissors. I started with the main shape of the blade, although I am a bit unsure on how to approach making the blade more blade like. I think i still have some angles and measurements to do. 

Reverse Engineered Object: Measuring the Object

I ended up deciding on doing the pair of scissors.

My next step in the Reverse Engineered object was to get as many measurements as I could using a digital caliper. I took not of those measurements in my sketch book.

All measurements shown in the images are in millimeters, and down to the nearest hundredth decimal point, so that when I begin to construct the object in Rhino3D, it will be as accurately to scale as possible.

Reverse Engineered Object: Selecting an Object

To help better my skills in using Rhino, I have chosen and object (or two) that i will reverse engineer and attempt to build using what skills I have, and will learn while trying to render them digitally.

The first object I chose, and am more inclined to render is a small key-chain compass.

The second object I was looking at, is a pair of scissors used for cutting hair.

I will soon finalize my decision on which object I will be doing, and begin to render it digitally.
