Looks good so far. It's always fun to see the differences from person to person in this process. For instance, I forge the edge thinner than 1/16" and take the point a lot pointier. The only thing I would suggest changing, is the draw filing. If it's perpendicular, it's not getting full cutting bene...

I use that style for forging all the time. I have a 6 pounder that I modified in that manner. I can switch from lengthening the piece to widening the piece just by flipping the hammer over. It's a lot more comfortable at the angle than a straight or cross pein. I also have a smaller, 2 pound that I ...

That looks a lot like one of the interations I went through when rebuidling my sander. Looks good! When slack belt sanding, unless you have a pretty good amount of tension, the belt will move unless you're sanding whatever right in the middle of the belt with no side pressure.

I'm fond of gas forges. They're pretty easy to build yourself. They give a really consistant heat.

If you want authenticity, you'd actually want hardwood charcoal instead of coal. And when you're done, you can grill on them.

As for how big, it depends on what you want to heat in it.

I've seen that forge on ebay before. I'm surprised that it takes 6 psi for forging heat. I'm really surprised that it doesn't get hot enough to forge weld. A blower isn't required for that.

Re: 5 foot diameter ring

Well, based on your definition of perfect, either really hard or really easy. I've made them with my ring roller and it takes longer to get the thing set to the right diameter than anything.

Now the machinist in me, would make it very hard based on the tolerance.... :lol:

I haven't heat treated armour pieces, but am used to heat treating blades and other things. The first thing you need to do, is harden it. Tempering comes after that to relieve stresses. The whole thing needs to be heated to temperature. For 1050, that's roughly 1450 - 1550 degrees. Then the whole th...

I don't know what hardness works best for stakes, but without know the composition of the steel, you could get a few different results. Some could harden sufficiently. Some could not harden at all.

Heat it up to the correct temperature and quench in the appropriate medium. Temper at the appropriate temperature for the application.

That's the basic process. Specifics depend on the actual chemistry of the steel. Is it known?

Nope, I cut the pattern before forging, similar to how you'd do ladder or pool and eye. I'll toss the camera batteries back in the charger and take a picture of the end when they're charged. There's not much to see. The tang connects to the cap, but doesn't extend through it.
