Heat treat to 65 70ish rockwell. @1400 deg for a hour .Then temper to 45R . @ 600 ish deg. For a hour and let cool very slow.

Fun ride, Adam, thanks for taking us along. Funny, no matter who or where, everybody thinks their 6" is 8" ;-) All the best, @HoneyOnWales

Thank you my friend, same to you!

4140 is .4% carbon. The first two numbers are your alloy, 2nd two numbers is your carbon point. So its a 41 alloy, 40 point or .4% carbon. Same applies to 5160. 51 alloy, 60 point carbon. 1095 is 10 alloy, 95 point or .95% carbon

Easier and cheaper to get a real anvil!

Nice job 👍👍

So Adam I don’t want to seem out of line but I’m just getting started with the cnc plasma and man I’m having a hard time getting good files to cut I mean I can make files but it takes huge amounts of time and if I’m going to make this table pay I need a jumpstart where can I get/buy files

Rusty, ur not out of line I'm happy to share my experience. One decision I made early on was to only make custom designs. If you cut the same stuff everyone else has you can only compete on price or finish. It takes a long time to get started but if you design stuff from scratch it will give you stuff no one else has and it will be easier to make decent money. Eventually all of your designs become jigs or tooling in your inventory. They even start building in each other. Imagine a cool layout that sells well and all you have to do it show it in 5 different fonts to get even more sales. I know it sucks to get over the hump but it will payoff in the long run. Happy making 😁

also, the edge is really important. You want jus the right radius, not a bevel. So much work is done on the edge... It's a neat concept but you obviously haven't done much blacksmithing. Neither have I but probably more than you. Search the youtubes for other people making anvils out of scrap. I wonder if you could use plasma table scrap to make non-standard anvils. There may be some market for small anvils. Japanese woodworkers, for example, are looking for a special anvil.

Great series, I mentioned a few ideas on episode one. Various and sundry vague memories include at 400* on clean steel water droplets will 'dance' across the surface. This is how I test the pan for my grandmother's Swedish Pancakes which are nothing like Southern Flapjacks. To harden and temper 4140 low alloy steel is opening up a can of worms to the 13 year old internet experts because there are so many different permutations and methods dependent on ultimate use. Generally speaking the lower the tempering temperature the stronger the steel, 400* is a good temperature for most common uses. I'm sure the bureau of standards must have a listing for anvils, they do for everything else.
