Northeast Dynamics LLC


Learning manufacturing the hard way — one carbon fiber part at a time.


How it Started

 Northeast Dynamics started during my freshman year of college as a half-joke between me and my friend (and now business partner), Michael Benjamin. 
We both own BMWs and spend way too much time modifying them. One day Michael bought a set of carbon fiber paddle shifters from a well-known aftermarket company. The paddles looked good — until the 3D printed plastic adapters snapped. What followed was months of some of the worst customer service I’ve ever seen. 
At some point we joked: “We could probably do this better.” 
Unfortunately, I took that seriously. 
After watching a few Easy Composites videos online, I became wildly overconfident and decided I would simply… manufacture high-quality carbon fiber paddle shifters myself. Compression molding. With resin molds. Made using SLA 3D printing. 
I knew absolutely nothing. But that didn’t stop me. 
CAD, Resin Printers, and Extremely Bad Ideas 
 
I started designing paddle geometries that didn’t exist on the market — fully curved paddles that followed the natural shape of your hand on the steering wheel and flowed visually with the interior. 
Night after night, I iterated designs and printed mold revisions at the Rochester Makerspace (thankfully open 24/7). I learned very quickly that SLA printers are amazing at surface detail and absolutely terrible at dimensional stability. 
Flat surfaces weren’t flat. Compression faces warped. Mold halves didn’t seal. I filled gaps with filleting wax and convinced myself this was normal. 
At one point I made a carbon fiber emblem disc that actually came out of the mold and looked incredible — until I realized I had to break the mold to remove it. 
I was thrilled anyway. It felt like progress. 
Pinholes, Reality, and Learning Manufacturing Principles
 
Once I started producing real paddle parts, reality hit hard. 
No matter what I tried — different epoxies, degassing, clear coats, post-processing — I could not eliminate surface pinholes. I learned (the hard way) that perfect cosmetic carbon parts require: 
  • Controlled temperature and humidity
  • Low-outgassing metal molds
  • Proper pressure and heat cycles
  • Industrial finishing workflows

In other words: not a Connecticut garage in the summer.
 
By this point, I had built a deep understanding of composite processing and mold design, but also realized that my original “simple compression molding” plan was fundamentally flawed for cosmetic-grade parts.
 
Delrin Molds, CNC, and One Week of Insanity 
 
When RIT finished building the SHED makerspace, I finally had access to real machining equipment — but the Haas CNC mill wouldn’t be operational for another four months. 
So I improvised. 
Right after finals ended, I spent about a week working 14–16 hour days designing molds, learning CAM, and machining compression molds out of Delrin on a large CNC router. I barely slept. I barely ate. I was racing the summer dorm shutdown deadline. 
Delrin seemed perfect: low friction, machinable, decent thermal stability. 
I made dozens of mold sets, packed them into my car, drove home to Connecticut, and immediately started producing parts. 
Thousands of Dollars Later: The Honest Pivot 
 
After another month of testing, I accepted the truth: 
To produce truly sellable curved forged carbon paddles, I would need: 
  • Aluminum or steel molds
  • Heated presses
  • Controlled paint booth environments
  • Possibly resin infusion instead of compression molding

At that point, the investment required exceeded what made sense for an early-stage student startup.
 
So we pivoted.
 
Instead of trying to brute-force perfect curved paddles, we shifted to flat carbon paddle designs that could be CNC machined by a high-quality supplier in Canada.
 
This allowed us to:
 
  • Maintain quality
  • Control tolerances
  • Reduce manufacturing risk
  • Focus on brand building and customer experience
 
Adapters, Suppliers, and Actually Shipping Products 
 
While all of this was happening, I was also designing paddle adapter systems. 
BMW paddle geometry varies wildly across generations, so I designed custom adapters for F/G series and E9x platforms. I prototyped them using resin printing, refined tolerances and feel, and eventually had them manufactured in SLS nylon through PCBWay. 
I also sourced magnetic adapter hardware from multiple Chinese suppliers and negotiated pricing and specifications to get the tactile “click” feel we wanted. 
Michael built a professional Shopify storefront, product catalog, and brand identity. We launched with live products and began taking orders. 
For a brief moment, everything was working. 
Tariffs: When Economics Beats Engineering 
 
Then tariffs happened. 
Shortly after our launch, new import tariffs on Chinese components jumped to over 100% for certain categories. Overnight, our cost structure collapsed. 
As a small startup, we didn’t have the capital buffer to: 
  • Stockpile inventory
  • Absorb margin losses
  • Maintain competitive pricing

So we made the hard decision to pause operations rather than ship compromised products or inflate prices beyond reason.
 
As of January 2026, tariffs have dropped to around 30%. We’re monitoring closely and plan to relaunch once conditions become viable again.
 
What Northeast Dynamics Really Gave Me 
 
Even though Northeast Dynamics is currently paused, it taught me more about real-world engineering and manufacturing than almost any class ever could. 
I learned: 
  • How CAD becomes physical product
  • Why tolerances actually matter
  • How material science affects cosmetics
  • How logistics can kill good designs
  • How difficult “simple” manufacturing actually is

Most importantly, I learned that building hardware businesses is brutal, humbling, and incredibly rewarding.
 
And I’d do it again without hesitation.
 
Status Note:
 
Northeast Dynamics LLC remains legally active and operationally paused pending improved import conditions. Product relaunch planning is ongoing.
