Re: Best Couriers to use for interstate deliveries.
I've sent tubes backward and forward to Canada with www.packsend.com.au for unbelievably good prices. Always been reliable, never had a problem. Slower coming to Australia than out, but still very good.

Re: other locally commercially or otherwise available timber
I don't entirely agree with the method of assessment in that wood database article. For my own consideration, I use Mod. Rupture for suitability as a backing, Mod. Elas as an indicator of stiffness (the higher this being the higher the Mod. Rupture & Mod. Crushing of your bow need to be) and Mod...

Re: Hickory backed White Cypress
It'd be great to have a wood backing that I can just lightly sand and glue on. Done. I have some logs of Elm I'm planning on sawing up into backing strips. Just another quick comment on this - Elm is an advised backing by many American bowyers, so that should work well. I've also used Red Oak (chea...

Re: Cutting Hickory Laminations by Bickerstaffe Bows.
Well, what if you were so set up a fence on the bandsaw to rip backings, but also set up a beveled board, maybe 1.5 inches high, just in front of the blade? In such manner, if the cross section of the board (or, beam , in your case) is a regular rectangle, then it might be possible to rip lams from...

Re: Hickory backed White Cypress
When do your bending experiments begin? If steam/dry heat don't work out, you could always try a kerf. Laminate a shim of cypress in the kerf & onlookers might never know how it was done. I've not done any kerfing yet, so it's definitely there as an option (and I am curious...) but it will be a...

Re: Hickory backed White Cypress
Would this be the same species as that seen in the fence palings at Bunnings and whatnot? I'd always dismissed it out of hand for being 'too piney'.

I've been asked to make a new string for this old bow, supposedly from the early 1960's. It may be of interest to some on the forum. The limbs are made from flattened tubular steel, 7/8" wide at their widest point. There doesn't seem to be an obvious arrow pass or rest, but there is a form of s...

Thanks for the clear & precise clarification, Perry & Dennis. It's good to see a 'correct' curve (I use the term 'correct' loosely, there is no 'correct' in many ways, so perhaps 'traditional' or 'most efficient' is a better term, not that I wish to start a debate or argument, please) plotte...

Re: Hickory, Ipe and Lemonwood...
Nezwin, like Big Bob, I think your hypothesis has merit, despite my previous arguments above. It is perhaps the most plausible of any in regard to central stiffeners and deserves some kind of follow-up. However, the final proof of efficacy is that on average, bows made with a central stiffening lay...

Re: Hickory, Ipe and Lemonwood...
Reading all this about Ipe & set, I've been pondering a few things for a while that might be relevant... Maximum Shear Stress occurs at the Neutral Plane. If the use of Ipe has caused less set to be taken, it would be as a result of Ipe's performance in Shear. Stick with it here because it goes ...

Re: Celery Top Pine
Nice work there Neil, its coming along!! For myself personally, looking at the tiller you have there I would soften up the tips a little to reduce the bend in close to the handle, particularly on the right limb. I think even for these bows you want a smooth even curve along the entire limb length (...
