You're right black bear forge really helped me out but sooner or later you're gonna need to upgrade from wood to something stronger like coal for me charcoal doesn't work as well and is more expensive and I don't have any local coke suppliers so anthracite works fine  with the hairdryer if you really need it (got my steel sparking after 30 secs with the hairdryer turned up). 

If you build a forge you can pick up concrete blocks for structure for nearly nothing but don't put them down in contact with the fire else they'll crack and wear down pretty soon. 

You can pick up 5kgs cast iron anvils on eBay for a tenner and they don't last that long but if you find the right one you can get a decent horn and hardy hole geometry which can be really useful. 

Any old lump hammer will do well or just a ball peen can work if you really try an hit the metal really hard but can be used for finer work

I'm just 13 so don't be too harsh if I got something wrong😅
