[TheForge] Forging triangles

Tue Oct 2 14:32:30 EDT 2007

The v-block is the way to go...one way to make it is to:

1. decide the dimensions of the spike
2.Hog out the triangle shape you want with a die grinder and press modeling
clay into the cut triangle, measure the clay impression, and refine the
shape and dimensions as you go. Repeat as necessary. You will get best
results with using a "cylinder burr" and a "tree file" in your grinder
3. This will be an open-face die
4.  make one of the spikes, measure the spike for adherence to spec, and
refine the die if need be
5.  Heat treat the die..consider using H-13 steel

I have had good luck making texturing dies with this method.  Note that the
more you want to use the die, the better the quality of the steel it is made
from should be.  Bon chance....

Like Albin says.

The problem is in forging a bar into an odd number of
sides.  Hammer on top, anvil on bottom, makes even
number of sides (2 [flat], 4, 6 or 8) easy.  For odd,
where do you hit?  A V-block is the obvious solution,
but not a shoo-in either.

If one angle can be nearly 90 degrees, then the step
in your anvil could be the V-block.  Otherwise an
upper or lower swage is in order.

For taper, you'll probably need a tapered V-block.
Not a real problem to make if you have access to a
mill.

All that said, you MIGHT be able to fake it using a
piece of roundstock bent hot into a "hairpin" (no
gap).  This, you'll observe, is almost a V-block.

Good luck
