Hi all and thanks for the answers. I appreciate it. Thank you James. I wasn't sure it's a good steel since I tried to scratch it with a cheap folding knife and I could. I'll see if I have the means to harden it here. The rod is a surprise. I found it near a road I was walking by and since I could scratch it with a knife I thought it's iron. The knife test is probably bad. Every unhardened steel will be scratched. About the disc, I was planning on using it a the base of my first forge. I wanted to make sure I'm not wasting high carbon steel. I'll try the big block with hot steel. Haha, nicely said. I was hammering the rod from the video on the blocks, cold. I thought it's 'soft' iron so I thought I'd use it as a test to see if the blocks are hard enough, and they dented, hence they are not hard enough. Now I see that I was wrong. Thanks for the scolding I'll keep in mind the need to temper it afterwards, and I'll look into attaching another steel to the top. Thank you. If it's grey cast iron it means that it's suitable for the forge, right? good. I agree with you. When I'll by an anvil I'll look into a good one. For now I'm trying to grow with the tools I have since my knowledge is little. The standing up rectangular block idea is interesting. I haven't thought about that. I'll sure try it. Thanks! I was thinking the same about the brake and the holes will be used to let the air from the blower in. That's the plan, at least. I wasn't familiar with 'post anvils' and searching for it brings up blocks that look very much like the round piece I have. This is very interesting and I'll look into it. Thank you everyone. I'll go do some experiments and learning and try heating my first metal work. Wish me luck
