Has anyone of you made wedges and feathers for splitting stone?
(as can be seen used here: YouTube - Breaking the stone
Do i need to use extra durable steel for the wedge?
One smith once said that you could use spring steel from an old pin-harrow for the feathers, and if you found some old hand stone drill (the one you hit on with a hammer, then twist a quarter turn and hit again to drill holes in stones) you could use those for the wedge.
What is your saying on this, i don't happen to have a lot of those hand-drills lying around.
i know that you should have the feathers thicker downwards, so that when you hit on the wedge it gives an even pressure all along the feathers.
oh, another thing, for the shaping of the feathers, who need to be round on the outside and flat on the inside, i need to make a hardy tool for that, what i the best way to make such. I doubt my little bench-drill can drill that large holes in a piece of steel. Are there common scrap-metal that have that sized-holes in them already?
I am a new blacksmith, and new to this forum aswell, so sorry if i have posted this in the wrong forum or such.
