Getting Ready to Leave

Today was my last day of class as college student, meaning a week from tomorrow I will be walking across the floor of the Convocation Center as I graduate from Ohio University. This experience is kind of a bittersweet one, one that I’ve never really had before.

Soon I will be starting a new chapter in my life’s book. One not centered around waiting on classes to start or end. It’s both exciting and scary as I will be coming into a whole new batch of variables.

The first few pages of this chapter will be finding an apartment for my fiancée and I while we remodel the farm house. Shortly thereafter, I will be starting my “big-boy job” at Honda.

With all of these huge changes coming in a very short period of time, I’m sure things will be hectic but I know that my experiences here at Ohio University will be some of my most cherished memories and that the Russ College has prepared me for life after college. For the last time, this is Steve Toth signing off. Stay classy, Bobcats.

One Month to Go

In August it was “one more year” now at the end of March its “one more month”. I never expected college to go by this quickly. Ever since pre-school, it’s been the familiar cycle of school, summer, school, etc. But not this time. This time I will finally be entering the working world as my formal education comes to a close.

College went by as quickly as everyone told me it would. My freshman year and days of living in the dorms are now nostalgic memories, campus has changed geographically since I first got here in 2011 with the addition of new dorms and sports facilities. Boyd Dining Hall has gone from the place you ate because you were desperate and lived on West Green to the most impressive dining hall on campus.

Everything I was told to expect was true. You will meet some of your best friends, you will learn more in these 4 (or more) years of your life than ever before, you will learn about yourself, and you will work harder than you have before.

My advice to any nervous incoming freshman would be to try and relax as much as possible. You will make those new friends, you will figure out what you need to do to succeed, you will make your own memories, and you will leave here a better person than you came here as. But for you and me, take a minute every now and then to appreciate the position you’re in. Because your college years are the quickest years of your life😉.

ETM Capstone Design Production Project

One special thing about the Russ College is that every major completes its own capstone course. For Engineering Technology and Management majors, that means designing and completing a production run like what would be found in a factory.

If you are not familiar with Engineering Technology and Management (ETM) we focus on everything in the manufacturing process from product design, process design, process improvement, process management, quality control all the way to technical sales. Our capstone course incorporates all of these into one intense semester.

We start out by designing a product. For my group this is a door side organizer which incorporates a shelf, a cubby, key hooks and a cast aluminum badge which I’ve mentioned in a previous blog post.

Organizer

After the product has been designed and then proven by a model build, the rest of the semester focuses on bringing it into production through the creation of tooling and the multiple control plans that dictate a process (quality, inventory, capacity, routing sheets, etc.).

At the end of the semester, all of these components are put into action in a production run with 15 finished products being produced in a five-hour period…followed by a three-day nap.

Senior year means senior design! During your final year in the Russ College you will participate in a capstone senior design project. The objective of this class is to use all of the experience you’ve gained throughout your curriculum to solve a problem or complete a project.

In ETM our objective is to come up with a product, propose the idea to the class and professor, and move on from there. We go through the original design phase, prototyping as a proof of concept, and a final production run. Regardless of the product you choose to produce the goal of the class is to emulate a manufacturing environment, where a part or product can be reproduced over and over again with little to no variation.

We track and control this variation through the use of quality standards and quality charts, ensure reproducibility through tooling such as jigs and fixtures, and train operators through tooling instructions and process sheets.

My group decided to create a collapsible dice tower.

The tower is held together using high strength neodymium magnets.

When the tower is disassembled it will fold neatly back into the catch box where the dice fall.

With our production run approaching rapidly I am very happy with how our project has gone so far and how our team has really worked together to get where we are now!

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.
