For most arrowheads I get a request that starts with the weight in grains for an arrowhead.
This means that I need to come very close to the target to begin with.
lets just say that I want to know how long a bar is 100 grains.
I know 100 grains is 0.014285714 lbs
I think 3/8 inch steel looks sane.
Linear weight of steel chart.
1 inch of steel is 0.014285714 lbs
0.014285714 lbs/0.014285714 lbs=x/1
x=.4606 of an inch which is worthless.
.4606 x 16 will give you 16th of an inch. or 7.37/16th of an inch per 100 grains
many people like 125 grain arrowheads so that makes 9.2/16th of an inch will be 125 grains.
This does not account for loss in forging or grinding.
For easy reference I created this table in inches to give a length of common bar stocks in decimal and 64/ths of an inch for 125 and 200 grains.
BROAD HEAD ARROWS
One of my good friends wants to participate in a clout shoot at Agincourt so he let me read a bit of
"Secrets of the English Longbow" By Hugh D.H. Soar.
The the pictorial display in the book is a good starting point but I feel it is lacking in some ways.
i received a request to make a set
1) do a reverse taper on 3/4 inch of 1/2 inch round
2)Flatten that sucker out to about 1/8 inch thick or a hair thinner.
3) cut the tines
4) spread the tines ( i used the hardy hole to spread em)
5)draw the triangle for the socket out using a cross pein
and spread the socket to a bit over 1 3/4 inches wide for a 1/3 inch socket.
6) roll the socket (I NEED MORE PHOTOS)
7)cut the arrow off
8) a miracle occurs. (YES I NEED MORE PHOTOS)
I spread out the head of the arrow and ground the tines.
