Ozbow

Actually, an endless string can also be made using nothing more than thee sticks stuck in the ground. The process is commenced by tying the start of the string to one of the pegs which are distanced apart to the required length and the string spool is passed around each end to bring the string to th...

Colin, Firstly, a few things about the video - 1. Jake has much better control of his bow than many of the shooters of English archers using heavy warbows. 2. That Joe Gibbs double Yew bow seems to be coming in the lower limb about where the whip-ending begins. 3. The width profile looks very much w...

Colin, Additional to Daryl's comments above - ELBs aren't good candidates for reflexing very much simply because of the greater loading on the narrow belly and the resultant string follow which cancels out the original reflex. I have made them by Perry reflexing by 5 inches on a 70 inch bow of 60lbs...

I have just posted that pic I was speaking about in my last post. I had a bit of an alzheimer's moment and forgot to do it. That actual second break sounds like it was from a fault in the wood itself more than the usual tension or compression fractures. However, the first break still sounds to me li...

As a generality, if the species in not on an endangered list and they have been processed,ie tanned, and are not raw unprocessed skins, they should be OK. It is the same with staves coming in from overseas too.

Sylakone, I have lightened your picture in Photoshop and marked the split which is just above the red line. That split under the glass looks to me for all the world like it has resulted from shearing forces. I know nothing of Merbau because I have not used it (I think), but where the split has occur...

Not for many years not, but I used to play around with the Plains Indians type bow which had very slight shoulders a la Holmegaard at about 6 inches back from the tips and a 'waisted' handle section with barely enough thickness to keep the outer limbs bending circularly. This one of yours reminds me...

DrAK, I go along with all above. I am tempted to suggest that you have have narrowed the outer levers to the point where their depth is greater than their width. That on its own will cause twisting if there is even a moderate amount of difference of thickness measured on either sidewall of this kind...

I feel reasonably certain that you once mentioned that, in the past, when you changed either your arrows or your bow, it would take you just a brief practice session before you would begin to group your arrows into the area where you were looking once again. If my memory is correct and this actuall...

but nothing can compensate for having arrows that actually shoot precisely where they're pointed, But that is precisely my point. They DO and have ALWAYS gone where I pointed. I have used different spines and weight arrows of same length on bows of different draw weight with the same result. They g...

Preston, Ideally, I would base my calculations on where the stave just begins to show set. Yeoman does the same as I recall. He did some bending work a good while back and came to a tentative conclusion that the maximum stress at that point on a sample beams he tried was roughly 66% of the MoR numbe...

Tommo, I have never ever had a broadhead fly badly to need to consider the bareshafting business. I have never had a problem with switching my field points to broadheads and having poor arrow flight. So, where is the point or need for me to bareshaft tune my arrows??? Mick, Working backwards, there ...

I wasn't thinking so much of making money. We just don't have the population here to support such a narrow market. I was thinking of just raw talent and ability like his. We would probably have heard about it by now if there were I suppose.

Preston,

I think you are right. What a sag it took at after 26lbs. Heavens!!!

Sy, Darryl is right about the grain orientation, and it will be a good bit of work to get the back crowned as he suggests. My limited use of Australian hardwoods leads me to consider that because they are perennials, they do not have the same degree of problems with splitting between the growth ring...

Colin, I will have to get one of them then. You wouldn't have the problem of the teeth getting blocked up either. Ballistically, there is an optimum elevation for maximum distance and it is not 45 degrees. I think it is closer to 40 degrees I think. I used to do some flight testing by standing at a ...

Preston, Backing your bow is probably not a bad idea but if you are able to work out a proportional difference between the load at which the Salwood starts to take set and that loading where it eventually breaks in tension, you can make the weaker (belly) much wider than the back by making a trapezo...

Tommo, Following Mick's list of references which I watched with interest, I have no doubt of its inherent usefulness as a tool to correct intractable faulty arrow flight, but only AFTER a problem has been established. From my personal standpoint, it is properly a second line remedy following the nor...

Colin, That IS a lot to lose. I hope it doesn't forbode the bow's future. How much do you think you will shorten it? Also, if you put a heat gun on the horns, it may loosen the epoxy enough to lift them off and you can just clean them up inside with your horn drill bit. Will you try the very heavy a...

Colin, She's a beauty alright!!! I tried my chords trick on your pic above, but because the bow is on a slight cant, it doesn't work that well. Have you got a tripod for your camera or are you using your phone? I have a little tripod for my digi camera which I bought purely for pics to go on the web...

Crumbs Colin . . . that was quick!!!! I would have still been labouring on the thing for the next week. I see what you mean by the slight amount of stiffness in the upper limb. If you have something with a straight edge which is about 6" - 8" long, with the bow on the tiller at say, half d...

I think you will find it is an optical illusion caused by the patchy plaster job on the wall and that the limb protrudes past the wall on to a dark background. I was thinking the same thing Daryl. Colin, Keep an eye on the mid-limb of that right hand limb. It looks to be coming there more than its ...

Yes, that will certainly be interesting. How much wider are you making this Ash bow compared to its Grey Ironbark predecessor and how will you orient the grain - vertically or horizontally? I think mikaluger has done a few of these.

Ian, Yes, they were better then. My old arrows are 5/16" and 9/32" and they are amazingly stiff. In those days they also made 1/4" arrows too. They even barrel tapered and bobbed them too even at those small diameters. A lot has been lost since those days. Perhaps there were more big ...

If they are in good condition on external examination and have a reasonable amount of recoil from bending, ie they don't stay bent when bent, they will be fine. I shoot some of my old target arrows from my collection which predate yours by another 30 years and they are as good as the day they were m...

Remarkable shooting indeed. Have we his like over here I wonder???

Awaiting with bated breath.

Any pics of the chrysals on the belly of the bow and have they developed into frets (pinches) already? Just curious.

For those interested, I have attached an article I reproduced from one of my books about the business of vibration frequency and amplitud in arrows because it seems to relate to the topic of bare shaft tuning as I understand it now. It is a Word document which can be downloaded dealing with how to m...

cmoore, I think you have done a good job on that little bow. As usual, I did a analysis of your tillering job which is actually pretty good even though my picture does not look like it is. I have rotated your picture so that your tiller is vertical. The reason for it looking wrong is that you have s...

Kendaric, That link you used as a reference has some very good points in it, especially that part where he advised to take your normal shooting stance with your non-dominant eye lightly closed, then bring your dominant eye vision around so that instead of looking past the bridge of one's nose, the m...
