From Raw Steel to a Work of Art – Why I Built my Plasma CNC

From raw steel to a work of art U Do It creates a multi-layer masterpiece for a fundraiser to benefit someone in need.

Fundraiser

I saw a friend’s post about a fundraiser requesting donations like baskets of joy. And I’ve always wanted to contribute in a meaningful way but didn’t know how. In the past we’d make a basket of soaps and beauty essentials. But I really wanted to give in a way that aligns with my heart and my passion.

My Experience

At this point I have made maybe 20 pieces of art of various sizes and complexities. My most recent has been a sign for our friends at the TV series Gravesend, which featured on Amazon Prime.

I’m not new to art but I’m definitely new to metal fabrication. Everything I’ve made so far has been for the purpose of learning and experimentation so I can learn more about the process. This also allows me to push the machine to identify it’s limits. For instance, this sign was made for RIM Cafe. I was ready to give up and not make it. The size of the lettering and how I would need to attach it to the RIM word was challenging. What I found out is that the Plasma CNC that I built was able to reliably cut 2mm holes. The screws securing the letters to the RIM word are 1.6mm screws. It is wild to me that I was able to achieve this. This was presented to Rene and Belle at the Gravesend Series Meet & Greet at South Phila at the Italian Market.

I Always Wanted a Plasma CNC

I’ve always wanted a CNC plasma table, so I spent over 5 months building my own from the raw steel tubing to the custom electronics. I was able to see the joy in the eyes of those I presented these pieces to. There’s more that I can do with it. I know there’s a reason why I built it.

It’s Becoming Clearer Now

The fundraiser post landed in my Instagram feed and I responded immediately. I seriously questioned my decision later. Why did I just do that? I’m committed now. I was originally going to make it open ended where the winner could submit their design. Then something came to me as a result of another request from a different friend. Why not make a seahorse?

The Seahorse

I went through some iterations but finally got to the point where I was happy with the Seahorse design in Fusion 360 (a computer aided design program). As this is being cut out by hot magma I still don’t have a vision of exactly what I want to do.

But then I lay the outline on top of the background and I begin to see a picture.

Now I just have to attack it with my angle grinder to give it some character. And I learned late in life that going perfect is not the answer. I intentionally left untouched areas with mill scale intact to give it some depth. some depth

Time to Play

Now that its grinded down it’s time to coat it and try out some mica powder on the seahorse backpiece. At this point I really think I got something good happening here. I coated this in full then began applying mica powder to it and adding more coating to it with an acid brush. And moving it around ensuring everything is coated.

Why I Built my Plasma CNC

Now I realize why I built my Plasma CNC. I’m able to bring an idea to life, stylize it, and donate it to a good cause for close friends of a longtime friend in town.
