I grew up on a farm, and have been a DIYer, Maker, Fabricator my whole life. I attended the University of Nebraska at Lincoln and earned a Bachelor's in Science in Mechanical Engineering. I then went to industry as a Design Engineer, where I worked at Caterpillar for 5 years and Case New Holland for 7 years. In 2015, I decided to go back to school for a Master's degree. I chose the Biomedical Engineering field because I wanted to stay in engineering and learn more about the ultimate machine, Humans! My favorite activity is riding and racing bicycles, learning more about how the human body works would give me a fundamental understanding on how to improve fitness, recover faster, design better bicycles, and improve the human-bicycle interaction!
If you see me in the Makerspace, say hi and introduce yourself, I am always happy to help out!
My favorite race is the Leadville 100MTB, it is an endurance mountain bike race with a 12 hour cutoff, riders must complete a 100 mile course at an average elevation over 10,200 feet in Leadville, Colorado. My finishing record is 4 for 4. Leadville Race Series website Rapidly become my new favorite is Gravel Endurance Races! Before coming to Tulane, I finished the Dirty Kanza, a 200 mile race, which is also the longest ride I've ever done! Dirty Kanza race website

Wood 1 Saw Handle Push Stick Pattern
If you would like to make a saw handle push stick for fun or for your Wood 1 training, here's the file! I laser engraved this pattern onto the piece of wood and then brought that to class, however, you could alternatively use the OLD SCHOOL CUT AND PASTE method! Yes, you guessed it: print the handle onto paper, cut it out with scissors, and then trace the design onto the wood. Not as technically cool, I know, but you will still end up with an awesome saw handle push stick (which could be engraved later!).

Custom Cycling Shoes Project
This year (January 2018) I have decided to start a long term project to make my own custom footwear! Shoe styles the world over are driven by elegant form NOT function! You know what I'm talking about; the extreme examples are narrow or pointed dress shoes! I don't know anyone with a foot that narrow and toes forming a pointy triangle... There is a new wave of shoe companies now making wide toe box shoes, which are actually shaped like your foot. Running and daily shoes are available (e.g. Altra Running Shoes), however no one is yet making a cycling shoe. Cycling shoe companies are notorious for making super narrow shoes. It is possible to buy custom made shoes (e.g. Rocket7 Cycling Shoes), Rocket7 makes some awesome shoes, but the custom work also has a custom price. I think I can Do-It-Myself for a fraction of the cost and it will be fun!
I am going to mix new technology with the old, however, most of this project will require learning an old world artisan skill, which is something I enjoy doing. I am going to document the journey here.
- STEP 1: Create a 3D CAD model of my feet. The Tulane Makerspace has an iSense 3D scanner, Here are images of the test scans I did for a proof of concept.
UPDATE: This is not a Makerspace Tool, but I was lucky enough to get access to a Creoform Go! 3D Scanner.
- STEP 2: After completion of the 3D models, I will next be creating a "last" this is the foot form that shoes are built on. Maple hardwood is the best material to use for a last. I am planning to use the Tormach CNC Mill to transform the 3D model into a wooden last shaped just like my foot.
A great advantage of having a custom pair of lasts is they can be used to make almost any type of shoe. If I figure all this out, I hope to someday make my own custom leather dress shoes from these lasts! Worst case, if I can make them, then I could send them to someone else that can!
UPDATE 17 DEC 2018: CNC Milling the maple blocks. Here's the work in progress:
So that's as far as I will get at the Tulane Makerspace. This first step of milling is the last thing I had on my list before heading out. I finished up my Master's degree this semester and have decided to not pursue the PhD any further. So on to the next chapter in life! I do plan to continue working on this project and I'll post updates when I do.
Once I finish up the milling of the last here's a summary of the next steps:
- STEP 3: Create the patterns - There are a lot of videos on youtube for how to do this.
- STEP 4: Materials - I have been scavenging eBay looking for old cycling shoes I can cut up and use the hardware from. Figuring out where to buy synthetic leather, foam, and fabrics is going to take some time and research. Finding materials may actually be one of the hardest parts of this project.
- STEP 5: Hand Tools: The best tools look to be made by CS Osborne, there's a few specialty tools I'll be needing. I already own the primary and most expensive tool for this project, which is a heavy duty walking foot sewing machine.
- STEP 6: The Sole - Originally, I was planning to do a carbon fiber layup, but after investigating it, I think I will start with fiberglass & resin, I think it will be a much simpler plan since I already have some experience with these materials.
Update: 11 Feb 2019 Bont Cycling has beat me to it! Check out their recent Facebook post:
The question for me now becomes, what do I do now? I still have a ton of work to do to make my own shoes. Well the answer is obvious to me, I'm done making my own shoes and I will now buy a pair of Bont's instead! (I will still finish my pair of Last's, but now that I am no longer at the Makerspace, a CNC mill is much more difficult to get access too, so Bont's timing is perfect.)

Here's my YouTube channel, several videos of my 3D printer and South Bend lathe are found here:
OpenSource 3D Printer
In 2013, I built my own opensource 3D Printer. I modified the Prusa i3 design. Controlled by: Arduino Mega + RAMPS 1.5 with Sprinter firmware. The frame is made from 1/4" laser cut steel plates and 3/4" lathe turned rods. The build surface is heated and has a 10" x 10" x 10" build volume. Recently, I made several improvements and upgrades, which include a large screen LCD with SD card reader, X-axis belt tensioner, print cooler fan, and a genuine E3D Titan Extruder, which I mounted Bowden style (filament drive is remote mounted like the Ultimaker configuration). Many of these upgrades were printed in the Makerspace! Detailed list below. Future upgrades include a BL Touch auto bed level and 1.75mm genuine E3D V6 Nozzle.
Several of the parts I printed in the Makerspace: * Tan LCD display box * Purple X-axis belt tension bracket * Purple Arduino & Ramps box * Purple Printer cooler fan shroud
If you are interested in building your own open source 3D printer, I suggest starting here: Reprap.org Also, the Lulzbot Taz machines are open source, all files to build their machine is available on their webpage! Same for the new Prusa printer recently added to the lineup.
1934 South Bend Lathe & Projects
This South Bend lathe is my own personal lathe, located in Nebraska. In 2010, I restored this lathe back to working condition. Over Christmas break (2017), I machined some small parts for my lab. These parts are cannula, used to mount soft tissues in our TA Instruments inflation-extension test device. The material is PEEK plastic, it can withstand the temperature of an autoclave, and machines nicely. Check out my YouTube link above, there is a quick video of the PEEK being machined.
