STEM: Mixing Old & New Techniques

As we dive deeper into building models in brass, we explore to utilize some of the latest technologies to develop the knowledge from the experience to make better models. We are talking here about such areas as CNC machines or 3D Printing to name a few. In addition, we will cross link with other STEM students working on their own projects to learn from their experience. Projects whether building a tool or a model usually has its own development life cycle. This is true on computer science software projects or small scale chemistry manufacturing control (CMC) processes that must be scaled up to a commercial production level and many others.

Steps along the way often cause us to stand back for a bite upon discovering a better method or an upgrade to improve the ultimate end results.

And rather than me simply telling you what I found that works, I will try to take you on that life cycle journey simply because it is an enjoyable part of learning that comes with building models. Plus the fact that I may have never actually tried out a methodology before myself.

In a future video we will elaborate on what we learned in researching our tank car project as suggested in a past video titled "CGW Tank Car Research & Development". The most likely scenario at this point is the fact that it is a welded car. What we have not talked about is how to make a seam between 2 sheets of brass that looks like they were butt welded. To give you a little something to think about ahead of time, it might be as simple as using a Dremel Rotary Tool with the right kind of attachment like a burr or cutter bit.

So, I invite you to visit a very inventive young man on YouTube in the Science & Technology field starting with his video titled "How To Make Perfect DIY Project Description".

Here is one of his tutorials on his project "DIY Dremel CNC" where many of the parts are 3D printed.

Most interesting is his DIY Dremel CNC video series. Keep in mind that we are aware of the fact that students do not always have the money and resources to go out and purchase whatever tools or machines that could possibly improve our model building techniques or speed things up with the fabrication for assembly. A Dremel CNC machine that can be 3D Printed and essentially assembled may not be any worse than building a specialized jig that we have talked about in prior videos. And the cost may be very reasonable.

So, what if we could etch or scribe the weld seams onto a flat sheet of brass under numerical control and determine if it will give us the proper visual effect.

Mixing the old ideas and techniques of model building with the new technologies can lead to new discoveries and innovation and it is my hope the Brass Investments Project can blend the two to build upon your knowledge base.
