Re: Burgonet build (critique please)
It is very obvious when you point it out. I am thinking maybe a bit of all three to even it out. Tilt the angle of the comb slightly, move out the chin and flatten the face a bit. Some millimeters on all three should do it I think. Looking at the graz it seems the bar goes inside the cheeks at nose...

Re: Burgonet build (critique please)
Hmmm I see 2 (3?) issues related to the mechanism of the front center bar. I think you want a leaf spring or similar to hold the bar down as some wise-ass is gonna try and spear-thrust to the top and open it up as a challenge. I'm also concerned that for that length unsupported except at top and bot...

Re: Dishing a spangen panel on the power hammer
That's a great design... for a specific radius.

Re: Tod and Co's Arrows vs. Armour Test
So this raises the question for me: "How did Medieval armours determine how thick to make the armour?" And this raises the answer for me "Clinical Trials". The HOW is by looking at the thickness of the breastplates of everyone who survived. There is a story about Henry Ford and the Model-T where he...

Interesting tech!
Be careful if you are looking for interior views of things like the sabatons as this is an image mapped on a 0 thickness surface. You still see the exterior geometry but with reversed topography, not interior geometry (so its hard to tell how much lames overlaps)

I don't much like the expression "compression articulation". It's not that it's not a useful descriptor, but that the term somehow carries a lot of "wow!" that it doesn't really deserve.

Re: The Palazzo Ducale bascinet.
Pedestal, definitely. If you go with a wooden stand it needs to be a deeper color and ideally shortened to LESS than the width of the steel, probably closer to the line between leather and maile. The pop of yellow and texture is distracting while the black pedestal is more invisible.
