Not My First Choice of Bow Woods…But

Generally I would place Ironbark way down on my list of bow woods because of its physical / mechanical properties. Making a successful bow could be a bit of a challenge.

The debarked billet 8’ long and 3 ½” across the crown used for this project had been sitting in my storage rack for about five years and was harvested two to three years earlier.

Whilst working the billet I was surprised that there were no drying cracks.

Because of the nature of this timber I believed that a flat bow offered the best chance of success and I went for a design similar to that of a flat bow found at Vedbaek in Denmark.

The differences in the properties of Danish elm and ironbark dictated that the limb cross section be quite a bit thinner.

The plan view of the bow is not perfectly symmetrical and some tooling marks remain. I was endeavouring to replicate a bow made with primitive tools some 6,000 years ago.

The finished bow is 70” n to n and draws 35# at 26” dlpp. This was the ball park weight that I was after as it suits the re-enactors.

Presently the brace about 5 ¼” and has a Fastflite Flemish twist string. Two coats of hand rubbed carnauba and beeswax was applied to seal the timber.

Looking Good, is it a shooter and what are the specs. Cheers Roadie

That's some sweet action mate, let us know how it fares with some use. What sort of draw weight is it

I placed some *'s between the text and images to make reading a little easier.

Nice one Daryl, that "primitive" look, both the finish and the shape is outstanding - though there's nothing primitive about them!

If I remember right, didn't Glenn Newell make similar bows from ironbark staves? I picked up a couple of boards to have a go with one day and it sure is heavy :lol:

I found this old image of bows made from Australian hardwoods.

At that time both Glenn Newell and Alan Jones were making these styles of bows but I can’t remember who made these particular bows.

Keith Keddie was making similar bows and I think his main timber was red ash [Alphitonia excelsa].

I sill have some ironbark from a billet that weighs in at 1,100 kg/cu/m.

That's the one I was thinking of, and I think there's another couple floating around on the interwebs (PA/paleoplanet?). Unfortunately I haven't been able to lay my hands on a stave of ironbark/spotted gum/stringybark yet to do a stave version, but I've laid out a board version which I plan on backing with linen at some stage. Them boards are heavy as you say! Haven't measured mine but they'd be up there somewhere I'd guess.
