    Improperly repaired anvil

    I built up the edges of my anvil with 11018, after preheating, with very good results. The built up areas have good rebound and are holding up very well.

    Trailer house steel

    It is probably high strength low alloy structural steel.

    What you have labeled 'Nozzle' is actually the mixing tube, but yeah, that is what I do. picture coming , if it came out.

    I have zero experience with T burners.

    If I was doing it, yes. Others seem to have problems with their flame nozzles burning up, so being able to pull the burner and nozzle out to replace the nozzle is an advantage. I haven't had that issue. A friend of mine sticks the mixing tube into a hole in the housing and builds his flame nozzle out of refractory. He's built several forges of different sizes that way and all of them are still running. We had three of them going at a meet at his place. Most people here weld in a pipe big enough for their flame nozzle to fit through I think.

    Well, then build or by your burners and see how big it needs to be. Personally if I were doing it, the inlet pipe would be the flame nozzle. Others do it differently.

    Do you understand that if your burner is tangent to the inside diameter and level to the floor, the top of the hole will be a lot more than 2.5" away from top dead center and it will not be a round hole?

    In the pdf all it says is this 5. Drill, or cut, a hole in the top (larger part) 2” down vertically from the top and if using one burner centered front to back. If using two burners put one about 1/3rd back and the other about 2/3rd back. By making this hole down 2” vertically from the top of the form you will have this hole positioned so that the burner can enter the fire box at a tangent or level to the floor, causing the burning gases to swirl within the forge. If you are going to follow those directions, you are missing the bold part.

    Tell me what you think - forge design

    I've had very good luck repairing broken bricks with Satanite. It gets much stronger after the brick is fired.

    PWS /San Mai Razor

    Thanks Steve No, I just dip the blade when I feel any heat. I keep my bare finger tips on the back of the contact point and with the blade so thin it is easy to feel any heat build up long before reaching the temper temperatures. You can't use much pressure anyway without fighting deflection on such a thin section. I run about 450 SFM when finishing the edge. Good eye. A 7/8 it is. I think several first razors and knives have been done on those 4x36 belt sanders. The main drawback IMO is the high belt speed. On a heavy grind you should be able to keep your heat down pretty easy though. Light pressure and bare hands.

    Another razor.

    First time attempting a forge build : bellows issue

    I glean charcoal from my fireplace in the winter, that way I get the benefit of the heat. I smother it in a 3 lb coffee can and by the time I've built up the coals again the batch in the coffee can is cool. Be aware of CO, though I've had no issue with it.

    Damascus with only hand hammers?

    I've been using .065" 15n20 and .125" 1095 lately. The 15n20 is what really stands out, so using less of it looks more balanced IMO. The size of the billet depends on what you are trying to make. If your making billets by hand just make your billet big enough for your project plus scaling loss and as small of an extra factor as you feel comfortable with. The scaling loss and extra factor comes from experience and how much manipulation you are doing to the billet. Keep good notes. Don't forget that small billets can be welded, manipulated, and then welded to other manipulated billets to end up with larger billets without having to work the large billet through the whole process.
