I made a $14 DIY poor man’s steady cam. It works alright. It actually cost about $14. It wasn’t very hard to find the parts or to build it. I warn you that you will need a drill bit that can penetrate cast iron. That might cost more than $14. Drilling through the caps was difficult, but not unreasonably…
In any case, the steady cam works, but it isn’t very professional looking. I don’t know if you would mind walking around a wedding with it. Even if you painted it, it might still look like some iron pipes.
