As I’m sitting in my apartment trying not to think of the cold outside, my mind wanders to summers past and the prospects of summers future. As I’m sure I’ve mentioned, in my free time, I enjoy restoring antique trucks and farm equipment. This past summer I restored a John Deere manure spreader for a client. Below is a before picture. At that point, most of the wood had significant rot and a significant amount of the metal had rust holes.

As the restoration process went on, replacement parts became a necessity and the search for 65 year old parts began. I was able to find a majority of the needed replacement parts from a salvage yard in South Dakota but one part eluded my search. The part was a sheet metal shield meant to prevent hands from being caught in the drive chains. These are often discarded to make maintenance easier. In the end, I was able to find a shield in a swamp in Illinois but it was in very poor shape:

Through my experience in design, I was able draft a replacement in SolidWorks and send the file to a local fabricator to be CNC plasma cut and bent to shape.

In the end, this fabricated part brought the restoration together and was the crowning touch:

Starting a Start-up

Spring semester marks that time of year again where you wonder what happened to fall semester and start to worry about things that are 15 weeks away. Recently I have been working to prepare for the launch of a new company that I’m a part of named sublit.

Sublit was founded by my good friend Marcus Yeagle, who is a computer science major here in the Russ College. Sublit is working to make students’ lives a little easier by providing a secure subleasing platform to list, and search for homes, or apartments. Sublit allows you to pay or receive rent payments remotely.

If you aren’t familiar, subleasing is something that students often do when they get an internship or co-op. If you end up getting an internship in another city you wouldn’t want to sign a yearlong lease to live there during the three month duration of your internship. A student leaving that city for an internship elsewhere would post their existing lease up on sublit for rent. Then you would only be responsible for paying rent for the couple of months you live in their home or apartment.

This also works for posting your own personal apartment up for sublease while you’re gone. This process can save you from having to make two rent payments over the course of the summer or semester. Its inevitable you will be hunting for an internship or co-op at some point in your college career, worrying about a place to stay should be the least of your worries!

Production Tooling Project

As the semester comes to a close, I’ve spent my final weeks studying for exams as well as finishing up final projects. One of the classes I took this semester was ETM 3510, Production Tooling. In this class we learned how to design and build a jig or a fixture. These devices help to ensure repeatability of a process and that each part run is created the same.

This class helps us to better understand how a large batch of items can be manufactured with little to no variation, and is also crucial for our senior capstone. We start by thinking of a possible design and then making it in CAD. Any revisions are reflected in the technical drawing prints. We use these prints to create our fixtures to our predetermined specifications.

For the last couple of projects, we were assigned to produce a physical fixture along with all of the technical drawings, parts, and documentation. These are the types of projects I really enjoy doing since we’re able to apply the methods learned in lecture into an actual product.

As the first half of my senior year comes to a close I would like to follow up on one of my previous posts about the fall career fair and the great opportunities it presented. During the fair, one of the companies I spoke to was Honda of America. Following the fair, I was offered an on-campus interview and was later offered an on-site interview for a position as a new model packaging engineer. Shortly after, I was offered and accepted the position which is in Marysville, OH.

This start to my career as an engineer is very exciting for me as a way to branch out and apply myself in a discipline that is not only new and interesting, but also presents the challenges of being a part of the automotive industry. It is also comforting to be able to focus on my studies in my last semester, which will be the most challenging, instead of searching for jobs.

In addition to finding a full-time job, I have been also accepted into a position within the Ohio Army National Guard as a platoon leader within a maintenance company, in order to serve my commitment with Army ROTC. Between working for Honda and serving in the National Guard, I look forward to the challenges I will be faced with and the growth I will experience from these challenges.

Beyond these two positions, I’m also looking forward to a project of my own. One of my life long dreams, which seems ever closer, has been to farm. Over the next few years I will be renting 55 acres from my parents in Lancaster, OH as I renovate not only the house but also the property in preparation to purchase and begin my lifelong dream of farming (picture below).

I have no doubt that the next few years of my life will be very busy but I look forward to the new opportunities and challenges I will encounter once my time at Ohio University is over.

Aluminum Castings

Ever since I took Metal Fabrication and Casting (ETM 2180) my sophomore year, I have been interested in castings. In the class, we were simply learning about the process. Now in my senior year, I’m delving deeper into the process.

One of the projects I have recently been working on is developing a casted aluminum OHIO badge using the sand casting process. My hopes behind this is to use the castings in my senior production run (capstone).

Casting

One thing that makes my development process different from traditional methods is that I have been developing and testing 3D printed patterns and runners which are traditionally machined or carved out. I started out with designing the badge using SolidWorks (a 3D drafting software). The part was then converted into a .STL file which could be read by the 3D printers owned by the ETM department.

Casting

Once the parts were printed, they were glued to the pattern board where sand could be packed around them. After the board is removed, a cavity is left for the molten aluminum to fill. As you can see, my first couple of patterns did not allow the sand to take.

Casting

After some massaging in the interior edges (larger fillets), larger draft angles and additional post print finishing I was able to create a workable pattern that was casted as seen in the picture at the top.

Now after creating a successful prototype and proving the concept, I have developed a (hopefully) ideal casting pattern that can be used in my capstone project next semester.

As my senior year goes on, the threat of real life comes closer. This past week, Ohio University hosted four days of career fairs, two of which were open to the whole university and two specifically for the Russ College of Engineering.

All four of these fairs were PACKED. Knowing that I need to find a full time job following graduation it felt really good knowing that Ohio University is there to help me not only to earn the needed education to succeed in industry but also provide the needed resources to find the job of my dreams.

Not only does Ohio University put on career fairs to help students find jobs but they also support an entire office with this sole purpose, the
Career and Leadership Development Center
(CLDC). This office helps students develop effective resumes, learn to interview effectively and learn to network. Additionally, the CLDC offers career coaching services and several workshops every semester to aid in the job search process.

One of the best services the Career and Leadership Development Center offers is “Bobcat Careerlink”. This is an online resource where students can find and apply for jobs and internships by companies searching specifically for Ohio University students and graduates.

With all of these resources available to us, it really feels great to be an Ohio University student where we are not just numbers and our faculty and staff truly care about our career success.

Summer Work in Athens

Fall semester is here which officially marks the beginning of the end of my time here in Athens! It’s time to start applying for jobs and preparing for the next chapter. While I’m sure I’ll miss Athens, I was able to spend one last summer here doing some really enjoyable stuff.

Ohio University hosted the International Space University (ISU) summer program here this summer. It’s an event where people who aspire to work in the space industry come from 31 different countries for a fast paced summer degree program to learn various skills, and network.

I helped transport people back and forth to the Columbus airport, which turned out to be a lot more fun than it sounds. I had the opportunity to meet people from all over the world, 3 different astronauts, various distinguished professors and entrepreneurs, and NASA engineers. I loved hearing all of their stories about space and work, and getting different perspectives from those who aren’t from the United States.

As well as helping out with ISU, I did some CAD work for the Innovation Center here in Athens. Using Solidworks, I recreated some old plastic Porsche 944 parts (as well as a few other things) and 3-D printed them out for a client who modifies this particular vehicle. This was especially cool for me since I’m a car enthusiast. I’m hoping to make my final year as enjoyable as this summer was!
