You have everything you need except the experience to know it. All that’s needed is something to heat, something hard to beat on, and something hard to beat with.
Don’t fall in to the trap of “I can’t do that cause I don’t have this”
If there is something you want to make but don’t have the right tool, you first make the tool. If you don’t know how then first research how to make that tool.
Ive made just about every tool in my shop and there is a pile of failures in the scrap bin.
To this day I still don’t have a “real” anvil and have no desire to get one.
You can can do it, there are just a few more steps to get there
