Archer Automaton

Posted December 07, 2016 4:29 AM by Del the cat

For ages I've been tinkering with the idea of making an archer automaton. There are some superb Japanese ones, but while they are incredible pieces of craftsmanship, the actual drawing action of the bow is all wrong.

I've just made a very simple prototype to prove my ideas... it's already being improved.
This very brief video shows it working.

Enjoy!

Nice work Del, I watch some of the other videos also that was also very good. (Actually an interesting documentary of sorts.)

Looking forward to more...

If you do a stop/go on the vid, you'll see the string (and arrow) travels up under a small ramp where his collar would be, this forces the arrow and string sideways off the fingers.
This video is helping me to fine tune that mechanism for the next iteration.

Nice work, I'd like to see the finished article when it's done.

Yup, rest assured I'll post it, it will take a while as it may need several iterations.

Very interesting. And clever.

A flaming arrow might be easier to find.

It was a little difficult to hear everything you said.

I think you said it was a Long Bow ? That is the video where you have a string attached to the bow and as you pull it, the gauge shows 20 pounds (?) .

You are standing in front of a brick wall and you have wrote numbers on the wall with chalk.

My question: what types of wood have you tried to use for a bow and what types of bow construction / manufacturing operations have you successfully attempted ?

The bow with the automaton is just a sliver of cane, I'll make a much better bow for the final piece.
In terms of real working bows, I've made everything from scaled down miniature Yew longbows, to medieval Yew warbows of 150 pound draw weight with a 32" draw.
Construction wise, I've laminated, spliced and backed bows of Hickory, Yew, Ash, Lemonwood, Hazel, Laburnum, Elder, Sycamore, Maple, Bamboo, Cherry.
I've had a few explode too.
I generally make self bows, that is bows of one piece of timber.
I don't "manufacture" a bow, I craft it, mostly with hand tools although I do use a bandsaw a fair bit, as roughing out a stave with an axe is rough on the elbows.
On my Youtube chanel there are two series of videos,showing complete builds one of a longbow and one of a 120 pound draw weight Warbow.

I have laminated Maple and fibreglass bows too, notably on a Chinese Repeating Crossbow.

That crossbow is interesting. looks like the bolts don't have any flights, is that how they would have been used originally?

Yes, that's right. I believe it was a relatively short range defensive weapon, imagine defending a doorway with one of those.

Wood work and wood work. Oh, man. Nothing smells like wood, Woody! Another thingy to add up the armory, Del?

Is it truly an automaton ? Marvelous as it is, I'd like some rear shots.With some gilt etc you might get close to the da Vinci Lion thing.

Seriously, it's a superb bit of worksmanship.

No it's not an automaton YET! Do pay attention...
It's just a prototype mechanism at the moment.
Finished thing may be powered by clockwork, electric motor, hand crank or nuclear fusion.

Could you design one that kept on working after you gave it an initial nudge? A sort of perpetually moving automaton....

Dear Del, In Indian Mythology there are many tales of wars. Most of the wars are fought with Bows and Arrows. There are many artistic Bows and Arrows which may be of interest to you. You can view them through Googles or I can send you few pics.

Hi, yes I've read some of the stories.
We have a picture on our fridge of an Indian (god?) with a bow, riding on a monkey :) with an army of monkeys.

Hi Del, It is from Ramayan our holy book. Lord Rama riding piggy back Lord Hanuman.
