View Full Version : Aussie Selfbows

In Australia we have a huge diversity of trees to choose from for our selfbow supplies. In the eucalyptus family we have around 370 species that are found in all regions of Australia and in the Wattle family there are over 700 species. Not all trees will make a selfbow but a lot of good self bows have been made from many species of these trees. There are plenty of other scrubwood and rainforest trees that have been used to make self bows as well.
With the correct limb design and tillering methods, good hunting bows with minimal string follow if any can be made.
Some of the standout hardwood timbers I have used so far are grey ironbark and red ironbark. Of the scrubwoods I have used red ash has been one of the best, red ash is one of the commonly known soapwoods, another soapwood pink ash will also make a serviceable selfbow but it does not have the same properties as the red ash. The pink ash is common whereas the red ash is a little harder to find, or at least it is around here in South East Queensland.

Even though building selfbows from all of these different timbers is fairly new in
Australia I have found references to self bows being made from Australian timbers going back to the early part of the 20th Century. One of the timbers I have found reference to in an American magazine back in the 1940’s is Ivory Wood, it is a rainforest tree which grows around Northern New South Wales to as far north as Bundaberg.

Australian timbers can be a lot denser and heavier than North American timbers and designing a selfbow limb so that the heavy timber does not impart hand shock is the hard part with Aussie timbers, especially when using dense timbers like ironbark and jitta.
There has been a lot written about building selfbows but most of the information focuses on North American timbers. I have found that when using Australian native timbers that most of the techniques especially about tillering is relevant but as for preparing the back of a selfbow from our native timbers it is not necessary to work down to one growth ring as a lot of or hardwood timbers do not have the pulpy layer separating the early wood from the latewood. With timbers like the ironbarks and spottedgum you can usually just plane the back down flat and go from there.

There are many timbers in Australia that are suitable for making selfbows such as spotted gum, red and grey ironbark, mountain oak, lancewood, soapwood and many more will make good serviceable selfbows. Depending on what timbers you use sometimes you have to change the layout of the bow to get the most performance out of a particular species of timber. You need to experiment with different bow layouts to get the best performance out of a species of timber and sometimes you may have to take risks and be prepared for some failures as one design does not suit all bows. Many of our timbers are denser and harder than many of the American bow woods with osage orange being an exception. Bow design and proper tillering techniques are essential to extract the most performance out of any stave. With some of the hardwoods like spotted gum you can simply buy shotedge decking boards and check that the grain is not running off at any sharp angles through the board and you can make a good board bow that will be capable of taking game. It’s a good way to start and you won’t have any trouble sourcing bow timbers at very reasonable prices, mostly under $10.00 per bow to get you started and it’s a good way to learn about tillering techniques before you start working on good staves from trees that you have invested a lot of time and energy into collecting.

Some of the best selfbows I have made from Australian timbers have had very thin bow tips as in the photos of the currawang bow and the red ironbark bow, the tips on these bows have no string grooves on the side of the limb but only a string groove on the back of the bow across the tip overlays to hold the string in place…Glenn…

G'day Glenn, thanks for sharing about selfbows; I think I'll give it a go one day, perhaps when I have a little shed. I've got Torges' book, and one of Hamm's books, in my library; but I think I need to take it a step at a time, and first learn the business with my Hill Redman properly, before embarking down the selfbow track. Anyway, all the best! Ben

Thanks Glenn for the information on the Australian timbers for selfbows,my son and I are keen to try our hand at a spotted gum board bow in the very near future.

You will never regret having a go at building your own selfbows Ben, even though building selfbows can be very frustrating. They do make you think and work out any problems you strike with them. I have one now that has me scratching my head as to how to save it as it is threating to let go on a gum vein that has revealed itself near the tip of the top limb...Glenn...

I imagine it would be the most satisfying form of archery and hunting there is.

Robbo the spotted gum has very good mechanical properties and it is very easy to source as floorboards. The biggest problen is that it does grow on the eastern and western side of the Great Divide. The spotty that grows on the western side of the Great Divide seems to be much better than spotty that grows on the eastern side. I usually go for the darker floor boards rather than the lighter ones.
I normally make spotty bows with the back narrower than the belly which reduces failures on the belly side...Glenn...

Ben, nothing better than shooting a bow for the first time that you have made yourself and taking game with one of the best experiences you will ever have. Selfbows made properly can be very good performers and give years of service...Glenn...

I love all your photos Glenn especially of the game you've taken with your self bows.
The top photo of that gnarly boar with dried mud on his shoulders and flank, set against the red dirt of Western QLD is fantastic.Taking game with my own selfbows is something I am going to seriously pursue over the next few years.

Have you got any more photos you can share?:)

What can be done with that gum vein to try and salvage that Ironbark self bow your working on Glenn?
Can you glue it and will it hold up?
Is it possible to open the sap vein slightly, insert the glue you use for your laminated bows and then clamp it closed? Would you have to remove some of the bittle sap first for the glue to hold?

Glenn

Paul I have tried filling it with glue but she had the creaks at 22 inches. What I can do is splice a piece of timber on the tip like a footed shaft, I have done this before and that has worked, and I could also try just cutting straight down the middle of the limb tip to just past the gum vein and glue in a timber insert, I haven't done that before but it should work.
I will have a look for more photos, I have some of friends with selfbow and all wood bow kills.
I will be hunting a lot more with selfbows in the future...Glenn...

I heard that creak on the weekend and I remember now that you told me that you had already glued it. That sounds like something to try, cutting down the sap vein, removing it altogether and glueing in a timber insert, I reckon it would work well.:)

Glenn, an exceptionally interesting read. If anyone had an scepticism as to the shootability and energy transfer of a selfbow, those photos would lay any doubts to rest- once and for all. Appreciate your time.

Gaday Glen...All those bows by the looks of things are shot off the hand..Do you build any sort of grip locator into them to get consistancy or does that just happen with time???
Thanks...Sparra

Gday Glenn great read including the pic's,
There are many Trad archers out here dying to read this sort of information.
Hope you plan to post some more in the near future.
Cheers

Thanks for the comments everybody. Norman when using arrows matched to your bow it is easy to get perfect arrow flight and penetration on game. I always pay a lot attention to spine and FOC.
Sparra I always use a handle wrap and arrow strike plate to achieve correct hand placement. If you don't place your hand on the same place of the handle and the string every time you change the tiller of the bow.
I do have more information Paul but I haven't done as much selfbow hunting as I would have liked to, it has been hard to get away for a hunt of late...Glenn...

I have made hundreds of selfbows from Australian timbers now and many from overseas timber species and have found that our timbers are the equal too and often excell anything selfbows are made from overseas . I honestly believe there is a cultural cringe when it comes to Australian bow wood , it cant be as good -the americans or the english or whoever don't use it . I can assure you they would if it was available to them .

Get out there people have a go , many Aussie woods are very forgiving of novice bowmakers , you can get away with bloody murder actually , for your first efforts with Aussie wood make the bow long - about 12 inches longer than double your drawlength and about 1 1/4 inches wide, dont narrow the handle , work the belly in a shallow lenticular fashion and tiller it so it bends very slightly through the handle and so that at full draw it forms a letter C . Alternativly study the photo's of Glenns bows and mimic those designs - technically you will get better performing bows with less handshock but for novices they are a lot more work . Have a go get the art of tillering right and then study the various designs and there benefits with the various Australian bow woods out there .

I just love it when someone challenges me with "You cant make a bow from that ! " Have a go you only fail if you don't and think of whats out there to learn . regards Perry

Glenn

G'day Perry, good advice there mate, some of the staves you have made bows from do challange the bowyer. As you say you fail if you don't have a go.
Anybody who does have a go will have failures, it's just a fact of life when you work with organic materials like timber but it is a thrill when you have a bow that works...Glenn...

Ive now got a mess of information on building a self bow. About 10 articles (including this one :))and 2 or 3 DVD's.
Hopefully my better half and I will be settled in the new house with my large shed in a couple weeks. Then 2 friends and I are going to have a crack at building our own self bows...

Good to see you are going to have a go at selfbows Bill. You wont ever regret having a go at building your own selfbow. The only down side to building selfbows is that it is very addictive and can take over most of your spare time at home...Glenn...

Yes the time is the prob when you also start making strings and the arrows and a bit of leatherwork and mabey a back quiver and mabey a knife or 2 I just dont seem to have the spare time I used to.You will love making bows but as Glenn said it is addictive and will break your heart when the first real nice one you make becomes a takedown after about 30 hours work.

Hey guys,
I'm really keen to start a selfbow. Being Puk's brother, I'm from the same knuckle dragging stock and so I also have a 32 inch draw for my compound. I've been told that for trad bows your draw is often (always?) a little shorter. Is there an exact amount to deduct or is it more of a "suck it and see" method for working it out? I'm keen to sort out all my important dimensions as soon as I can coz I've got three weeks holidays starting from this coming weekend (the joys of teaching:P) and it would be a great time to hunt down a stave and get shaping!

Jono.

Glenn
20-06-07, 09:15 PM
Hefty normally it is at least 2 inches shorter but it can be more with a selfbow. With selfbows the shorter the better, you might even lose 3 inches because of the way the bow is held...Glenn...

Glenn (and anyone else who's good at this stuff),
I'm looking to make a self bow from spotted gum (eg a floor board) for my first attempt. I'd like to aim for something that would have acceptale poundage to be usable for hunting (if it works out;)). could you give me some suggestions for what size board I would need to get for the stave? If I use an actual floor board, would I need to add a thicker section in the middle to shape a handle or can you find pieces thick enough?
And probably most importantly, I'm sure if you know where to look there are a lot of good books on bow making (bowyering?). Which ones would you recommend?

Any help would be awesome.
Cheers!

Jono.

Hefty, one of the best books to buy to start out with is the Bent Stick by Paul Comstock, real good book and simply written, and when you have done a few and you want to go to another level I recomend you get Hunting the Osage Bow by Dean Torges.
If you are going to use a floor board you will be restricted to 19mm thickness. You can make a bend through the handle bow which would be the easiest way to start or you can glue a doulbe thickness in the handle section to make a deeper handle section. The deeper handle wont have as much hand-jarr as a bend through the handle bow but will be a bit harder to make for your first attempt.
You could start out with a bow 2 inches wide and if she is too heavy and you want to reduce the weight you can take timber off the width so that you don't end up with a bow that is too thin in depth. If the bow gets too thin in depth you normally find the bows become a bit doughy and lacking in peformance. Timber is twice the strength in width but is four times stronger in depth. If you have a 25lb bow and you doubled it width the bow would be 50lb but if you doubled the depth the same bow would be 100lb...Glenn...

Thanks Glenn,
I think I'll try to add a section for the handle. While I've never built a bow before, I'm fairly confident working with timber because I'm a Design Technology teacher.
I did a search for books and had come across "the bent stick" but only on American sites. Do you know if I would be likely to find it in any local store or would I just have to order it?
LOL, I'm so impatient I don't want to wait for the shipping! I guess in the meantime I can track down a board with nice straight grain and cut it to 2 inches wide and prepare a handle section.
Thanks for all the info!
That's why I love this site!

Jono.

I think one of the Archery shops in South Australia use to carry the Bent Stick, can't remember who it was now but I think it was Archery Academy...Glenn...
