Arrow Head to Arrow Shaft Mating

02/01/2012 7:36 PM

Guys, Girls and Cats,

What would be the ideal or standard shape be for the end of the Arrow Shaft to mate securely to a forged arrow head?

After looking at some of Del's posts, I am going to try to duplicate not just the heads (bodkin and broad heads), but hopefully the tooling to "mass produce" them as would the armorers of old.

Since the archery equipment readily available in my area is all modern aluminium shafts and screw on heads, I'm not sure on what the shape of the end of the shaft should look like.

Any ideas would be much appreciated.

Thanks in advance,
Sapper

I think it depends on how you plan to attach it to the head....We used to make them out of hardwood dowels and just sharpen the end...old keys can be made into heads and attached by cutting a slot in the shaft...The balance is very important, see links..

Without looking at Wikipedia, I would forge a deep vee in the arrowhead to accept a shaft with a matching deep vee. Both would be fairly simple to do with standard tools. I would then look for a natural glue or sap to fasten them together.

I think lashing was done before, but I like glue. During flight and impact, the forces of acceleration and the glue should keep the arrowhead on long enough to do it's job. It's only during transport that the arrowhead gets impacted in other directions.

A typical field arrow (hunting) is a wooden shaft which is sharpened in basically a pencil sharpener

The heads have a mating (female) cone - much as wood shaft target tips do.

They are attached with various adhesives - commonly epoxy, but I use hot glue or Urethane Bond as it's a bit flexible and less shafts get broken if the head hits something hard.

It's very old and proven methodology, dating back to smithing and tree resin

Batt, Thanks for the offer, but I'm more interested in replicating the process of how the old style arrow heads were made and secured. Basically the forging and mating. I'll shoot what I make to tune them so they shoot straight. Regards, Stuart

Arrows from the Mary Rose show they were tapered to push into the socket on the forged head, they were fettled to fit, so there was no fixed 'standard' although they were similar.
The arrow heads would have been forged around a mandrel.
Not usre what they were stuck on with, resin? pitch? Hide glue? Araldite.
Interestingly they didn't appear to make so much fuss about matchig arrows to bows as we do these days. Most of the Mary Rose shafts were Poplar wood.

I would use a .75"/ft, self holding taper. It is the best shape to secure a point and it leaves more conacte surface an shaft material under the point.

Simple is better

Well I would think the bigger the head the longer the shaft......vise versa the longer the shaft the bigger the head.

Hahaaaaa - quite funny, but you also raise the point of broad heads interfering with spin, so stability, range and accuracy.

There is actually quite a challenge matching broad head killing effectiveness parameters to an "aerodynamically small" head design.

Simple conflicts exist, such as if you 'twist' the head to match the fletch rate, it's a manufacturing and sharpening nightmare.

Especially when the best killing result is a razor like sharpening geometry, which is 'weak' and tears its edges on entry, creating the greatest ripping of organs etc.

Not on that site I linked to it seems, but there are tips available that use replaceable blade inserts.

It has long seemed to me that there is an opportunity to marry this insert approach to the aerodynamic and effectiveness parameters, better than current art does.

Taper used on arrow heads I have designed are 12 deg included.
