Valcohol Bar Cart by Will O'Connor

As you may or may not know, Val, my wife, is a badass risk-analyzing actuary by day and vibrantly creative mixologist by night. She is constantly inventing new cocktails and photographing them for her blog, Valcohol. I wanted to surprise her with an elegantly designed bar cart to complement her design aesthetic and provide a beautiful piece that would serve as bar storage as well as a surface for photography.

Conceptualizing the design brought me to the complex relationship of cocktails and Prohibition; the lack of easily available spirits pushed the limits of mixologists' creativity, resulting in some of the best classic recipes emerging from that time. Therefore, pulling design elements from Prohibition-era times was a logical choice. Imagine reading The Great Gatsby by F. Scott Fitzgerald; if he were to describe a bar cart in Jay Gatsby’s mansion, this is what I would have imagined it looking like.

The drawings below show my first conceptualizations of the design. 

I wanted to make a wood cart with metal accents; that would allow me to make sharp mitered joints in the frame plus visually minimal rounded metal accents. I thought taking a very geometric pattern with intersecting lines and sharp corners would be a perfect focal point for the top shelf of the bar. A great way to make that element pop would be to engrave it with a wood router and then paint only the engraving gold surrounded by a contrasting dark wood. Square-cross-section posts flanking the corners of the shelf would provide support. I could craft a handle into the posts by jogging a section of the posts away from the shelf, then joining two adjacent posts along a short end of the shelf. Metal rods would span across the perimeter of the shelves providing both security and an appealing visual accent. Wine glass racks mounted under the top shelf would provide a display area for fancy glassware. Lastly, decorative yet functional caster wheels would allow for simplified movement of the cart for photoshoots.

Below is a rendering of the model I created.

I teamed up with my buddy and was able to utilize his CNC router to make the engravings on the top shelf. I wanted to make the cart free of fasteners for a very clean and refined appearance. Therefore, I had to be very creative with the design to provide the necessary support. I used a table saw to slot the posts while mounted in a jig so that they could slot snugly into the notched corners of the shelves. With the slotted design, wood glue provided sufficient strength to hold the cart together. I cut holes into the posts to hold the metal rod railings and assembled the cart with the railings permanently in place. Utilizing jigs during the assembly process allowed me to square off the posts to the shelves. I added structure below the lower shelf in anticipation of the weight of many bottles.

Here are some of my in-process photos.

For my next cart, I would use a liquid–based metallic paint in lieu of the wax-based I used for the cart. Though the wax can hold an amazing amount of metal fleck, working with it was arduous and was not worth it in the end. Though I had computer models and drafts for parts, I was creating parts by hand. In anticipation of this, I made jigs for cutting slots into the posts. Despite this, there were some gaps to be closed with stainable wood filler upon final assembly. Improving the jigs and buying tools made specifically for some of the cuts I made would decrease the amount of manufacturing time and post-processing that was needed.

All of that work was well worth it though to see Val’s reaction when I surprised her with the cart. She promptly made a cocktail to photograph on top of it.

Bicycle-Powered Mobile by Will O'Connor

I am lucky enough to have an incredibly creative and inspiring family. My sister builds exhibits for Children’s Museums in Minnesota, and I am always in awe on the ideas and installations she develops. So when she asked me if I wanted to design a bicycle-powered mobile exhibit at one of the museums, I immediately jumped on the opportunity.

The basic concept included:

  • A children’s bicycle fixed to the floor
  • A mobile in the ceiling with clouds, stuffed animals, or other items attached to it
  • A device to translate the pedaling motion of the child to the rotation of the mobile

The drawing below shows the concept as envisioned by the museum curator.

To match the aesthetic of the rest of the exhibits, I used plywood and other wood products. To ensure serviceability of the system, I sourced all purchased parts as off-the-shelf bicycle components or from McMaster. Since the museum wanted the exhibit oriented in a specific way in the ceiling, I needed to change the axis of rotation of the chain by 90 degrees, thereby requiring the use of a transfer case. I created all of my parts with slots and tabs so simple tools and fasteners could accurately make assemblies. This allowed me to avoid the need to make precise fixtures. Additionally, slot and tabs provided me with the ability to use pocket screws to fasten plywood in the stronger, cross-lamination direction.

CNC machining provided an easy way to create the level of precision needed for a slot and tab design. I teamed up with my buddy who owns a CNC router to manufacture the component parts. 

The original intent of the mobile was for it to span across the ceiling, but to ensure a safer installation the transfer case and idler case were mounted so the chain ran parallel to the wall. The design shown on the left is my original conceptualization of the installation and the design on the right represents the final installation, after adjusting for the updated mobile orientation.

Slots in the mobile mounts were needed to provide a method to tension the chain as it wears over time. I designed the mobile parts to be mounted to the chain with jeweler’s wire, allowing for minimal interference with the chain rings.

The transfer case required the most attention to design. It included multiple bevel gears and bearings and needed the most precision to function correctly. The main hurdle of the transfer case was creating an axle that would react torque through the bevel gears and bicycle chain rings. Using long 3/8” shoulder bolts provided a precise diameter for the bevel gears and bearings as well as the threaded section for a chain ring adapter to be mounted. The idler gear case was simply the same design of the transfer case with the bevel gears removed.

The last item to design was the stand and rear hub for the bicycle. A fixed-free rear hub (freewheel on one side, fixed gear on the other) was needed to avoid counter-rotation of the chain. The likelihood of the chain derailing unintentionally would sharply increase if the operator could pedal the mobile chain forwards and backwards. The stand was basic and provided support for the rear axle and a mount point for the tensioner on the chain running from the bike to the transfer case.

Given the opportunity to expand the installation in the future, I would add multiple idler gear cases to route the mobile chain into a visually compelling design on the wall. The installation went live on Earth Day 2017 in the Grand Rapids, MN Children’s Museum and was very well received.

Welded Steel Sculptures by Will O'Connor

I began welding when I was 9 in response to my mom's question "what kind of art class would you like to take?" I started taking welding courses at the local Minnetonka Center for the Arts after school and so began a lifelong hobby. 

Cooktop Lighting by Will O'Connor

I redesigned the base to this cooktop lighting fixture to compliment the futuristic geometry of the three pendants. Realigning them in a row rather than a circle provided improved light distribution as well.

Hurricane Lantern Electrification by Will O'Connor

The design of vintage hurricane lanterns is irresistible, but burning kerosene in the lamps indoors just isn't feasible. I restored this lantern to run an Edison filament style bulb using the fuel cap as the dial to operate the dimmer switch. My main goal was to complete the integration of the electric bulb so that the lamp could be converted back to oil as well as having all of the electrical components hidden.

Routing cables through the arms of the lantern was extremely difficult due to the initial design of the lamp. Though there were pre-existing holes and access points to the arms, they were small and had very sharp edges due to the very thin gauge steel used in construction. For the next lantern, I will route the cables through the side of the lamp for safety and simplicity. The Edison style bulb could not have been any larger or it would not have been installable inside the glass chimney. A shorter, Edison-style bulb would be better.  This lamp found it's home, very appropriately, in a turn of the century cabin near Castle Danger, MN on the north shore of Lake Superior where it once again can provide comfort and solace to those unfortunate souls stuck in the midst of a Nor'easter.
