Design a clock that will be CNC milled. The design parameters were only that it is contained within a 12x12in stock, and that the wood be derived from a wood salvage yard, which we went to (Heritage Salvage Yard, Petaluma). Because of the clock movement mechanic included, it was basically a garuntee that the final product had to be wall-mounted. For the clock hands to fit, the wood piece had to be around 3/4" in thickness with the bottom cut to fit the mechanism.

4/26/2024: Visited Heritage Salvage and obtained the wood used for my final piece.
5/3/2024: Had a tough time with adjusting the original model so its height was equal to my stock.
5/16/2024: CNC Milled the CAlock.
5/17/2024: FIxed the backside being off and added danish oil to the clock

Especially when it came to the bottom CNC being offset from the top, this was a very permanent problem, and I found a fix that would not interfere too much with my current design. Making minor adjustments instead that solve my issues is something that I really need to work on.
In the beginning, I was faced with the challenge of how to cut a model that I knew I could not create with my very own hands. The savior of this daunting challenge came when I learned that Fusion has a tool that converts regular 3D models into bodies that can be edited how I knew best. Because of this, I only needed to find a free model of CA topography online (which I did).
First, I used 3D adaptive, and it took 1:20 min, and it never seemed to finish computing. Then, I was introduced to the ball end mill and the Parallel tool on Fusion, and the process was trimmed down by 35 minutes. The topography of the clock looked much cleaner after adding a horizontal pass, which acted almost as a contour.
The tool paths themselves are no different; however, the orientation of the setup is changed, and the origin has to be placed in the correct spot so that the part can be correctly flipped to do both sides with the correct orientation.
To stain the wood and make it look less basic, I applied Danish oil to the wood. Although the application process was very simple, there were safety precautions that I had to strictly abide by, such as applying the oil outside or shutting the cap FULLY shut to decrease the chance of it spontaneously combusting.

Make sure that the stock used has the exact dimensions listed under Fusion. As you have to do both a bottom and top cut, not being accurate can cause each toolpath to be offset from one another.
Triple-check and ensure that your clock's hour hand has enough clearance to not collide with any part of the design.
Give the clock shaft around 0.1" of clearance beyond the shaft's actual dimension.
Simple exterior yet complicated/challenging design process has been my go-to for most of my life. I personally prefer designs that are not too complicated (hard to look at) or not too simple to the point that they look bland, basic, 0 personality. Based on this, I find my CAlock to fit the bill because of its simple outline yet complicated geography presented when looking closer.
I demonstrated growth by challenging myself to complete something that I had no clear path toward producing, although it eventually became clear, even with some hiccups along the way. Challenging yourself in this style is a great way to grow as a person (in this case for Fusion skillset), as it is sure to provide new knowledge and things to avoid from the mistakes made along the way. I hope to further imbue this into my life beyond fabrication.
The main skill I learned during this project was using the Planer that our machine shop holds. Until this project, we only used wood that was bought in perfect shapes & sizes, but as we used recovered wood for this project, this was not a guarantee. Before we could plane the wood pieces, we also had to use a metal detector to remove any hidden nails (which there were a few).
I believe I spent my time wisely in this project specifically because I began designing the clock earlier than we were meant to (I wanted to make it so bad). because of this, I do not know for sure I could improve my time management in terms of this project.
I learned new safety precautions when using the planer, which can kick back like a table saw. There is a team-work needed to handle the large pieces of wood that we inserted into the planer, so I think I need to focus on better communicating with others when a machine is running (the planer is really loud).
I left my comfort zone when I decided that I wanted to create something that I did not know how to create within Fusion 360 itself. Finding a way to import the topography of California into Fusion as an editable form was a daunting process, but I was able to figure it all out with the mesh-to-body conversion tool.
I wish I could have had more time to change the hands on the clock to more unique designs. One of my brainstorm designs was to have a clock with "floating" hands, and I wish I could have figured how to achieve such a thing in the CAlock. I also would have loved to somehow implement fun facts about the State into the actual clock design.
