Custom bowyer of high performance bows.
our little adjustable strike plate and how it can be used.
Holistic bow design and understanding based on 24 years of enhanced torsional stability has shown us that extra over centre helps.
So this leads us to making industry leading risers, and methods of controlling centreshot.
Hope this helps explain how our strike plate works.

we pioneered torsionally enhanced limbs. and we have been working on how to exploit that using the limbs geometry. @JakeKaminskiArchery here is what I wanted to say when I commented on one of your videos several months ago.
stack. what is it? why are we so rubbish at what it is?
Переглядів 6543 місяці тому
how to define stack, well. you cant, but you should be able to. it is just not defined. we can't even define the equivelant of average, to then be able to define the standard deviation. which is crazy because all the marketting states. smoother than last years yet never is.
smoothness on a scale of 1-10

how to discribe smoothness. the DFC tells all. we use a scale of 1-10 to discribe our models we dont just tell you "it's smoother than our last model" we actually put them on a chart. we state where each model sits. we don't tell you it's got bamboo therefor it's smooth. bamboo does nothing for the DFC. utterly NOTHING. and I can tell you why.

Hi i m sure you gave the answer in your video but as i m french it is possible i have not understood every details. For the COVERT HUNTER and for a draw lenght 31" which is the best way : big riser and small limbs or short riser with XL limbs?
@@PaulGramola yes. XLs
@@BorderArcheryLTD XL limbs whith short riser that it?
@@PaulGramola riser length depends on your shooting style. So there is no best. No point in a 25" riser for hunting, or a 17" to shoot 18-90meters
Hi Sid, I love your videos and learned very much, thank you. I had emailed you about purchasing 4 Tempests to China but got no reply.😓Sorry for my bad English.
I truly appreciate your videos. Thank you. In the string-walking barebow community, there are those who practice "reverse" tiller with respect to recurve type bows. This seems so wrong to me where I feel that "even" tiller would be the absolute most adjustment needed for that technique. Please advise.
@@arrowdodgerluvsmarlins1758 all depends on where you press through the grip. Tiller is a relationship of three things. The bows geometry, where you pull from, and where you push from. All three are inter related
Love you sir full support i love bows ❤
Hi Sid, I've been watching your videos for several months and I don't stop learning, learning with reasons and not because someone says so. If you decide to give training it would be a great success, I know you don't need it, but I think there are many of us who do need it. It's an idea. Thank you very much.

I love your explanation style. Practical geometry paired with a little physics and spiced up with a bit of biting humour. I've learnt a lot from you so far, thank you for that! Greetings from Germany
Thanks for appreciating the humour. A lot of folks don't get it. A little sarcasm never hurt. 🤣
Cool. Thanks for sharing.
Great video. As always thanks for sharing your knowledge.
Now get WA accept this in the Traditional class, PLEASE
Yeah...I got weights above centerline for barebow changed. And I stopped the crazy rumours of max riser length at 23" and the odd wood requirements.... but im thinking a static solid strike plate might be a step too far for them LOL
Thanks

Thanks from Granada(Spain)
Good video and explanation. Perhaps you can further show the differences of string angle measured at the arrow nock with the different style bows at full draw.
People love numbers. Even if they are insignificant in difference, they still hold them as a triumphant difference. For example 99% of folks don't know the angle difference between a 68 and 70" bow, let alone the difference between 68-70 or 58-60. So pontificating the impirical difference between a super recurve and a mild super recurve or a traditional recurve or a longbow seems superfluous When ATA is abandoned, its about 1/4 of a bow length. For a 68" bow. Maybe a 1/3rd on a 60% bow for a huge hex9 vs a conventional recurve from memory.
Thank you for that , Cheers from Ayrshire
I thought it was more to do with draw length than anything else
Limb length is for draw length, riser length is more for shooting style.
Wonderful presentation, can you give me a recommendation for my bows brace. I have a Hoyt Satori 21-inch riser with the long recurve limbs. Thank you.
@@hoosierdonkeys8073 who ever made the limbs should have done thier homework. We know our limbs.
BOarhrghdr Archery
A lot of great information to digest. Might have to watch it a few more times.
Fascinating info. I have just gotten back into making bows after maybe 15 years. I have made about 85 of various types, self, laminated , all bamboo, long bows ,recurves, now trying Turkish horn bows. Your explanation of limb rigidity and resisting twisting of the tips is so well explained. Cross weave carbon is something I never knew about till watching your videos. Especially interested in the thought of narrower dimensionally stable limbs. The cube rule of stiffness says that a piece of wood, ( or bow limb)? that is 1 wide by 1 thick it has a stiffness of 1. 2 wide by 1 thick, a stiffness of 2. 2 thick by 1 wide a stiffness of 4!! Think Howard Hill style limb as you talked about. Once again, fascinating info. Thank you so much. Much food for thought.
@@russparker1647 lots of bowyers seem to find our info interesting, while it's my opinion that should have a depth of understanding that touches on this.... sorry for my reply. It seems the last 4 or 5 coments on here are from bowyers.
Alternatively you can get a heavy arrow, that shoots between 100 fps and 150 fps, and use the equation: ft lbs energy = ( <arrow weight> * speed * speed ) / 450240 The reason for the heavy arrow is that bow efficiency goes down with lighter arrows. So to see the actual energy of the bow you need a heavy arrow to take more energy away from what gets wasted to move the limbs. If you use a normal arrow the higher speed of the arrow limbs will be taking more energy that would be going to the arrow.
@@musikSkool limb construction changes efficency too, the difference in dynamic mass of a limb can be nearly 20%. The dynamic mass has nothing to do with stored energy. There are very very few genuine carbon limbs on the market, most have a glass fiber content. Real carbon laminated limbs really excel in the dynamic mass stakes. Dynamic mass doesn't just include limb materials, but also includes working limb length.
His HEX 9 are 1.29 ft lbs energy per lb of draw. A normal Olympic Recurve is around 1 ft lbs energy per lb of draw. He has gotten pretty far into compound bow territory for efficiency. Those max out at 1.4 ft lbs energy for 1 lb of draw. He has gotten really close without needing cams. Respect for nearly perfecting the artform.
@@musikSkool the highest prototype stored energy limb we have made peaked at 1.32se/pdf. We have also achieved 2.7lbs of letoff. The 1.32 was shootable, but letoff creates a issue I don't think is solvable under the guise of a recurve. The cams need synchronised with letoff
Would the lightest bow possible for a given draw weight be a recurve or an RD longbow?
@@musikSkool we think we could make 6lbs with our current setup, which would have a standard product DFC. And still maintain torsional stability
I hear what you say about marketing and (general) people liking uses labels, I completely get that, but I’d also bet at a much greater % of your real potential customers wanting to know (and being able to comprehend) the reasoning behind why these labels are given. From everything I’ve heard you say about superrecurves why would I, as a mainly target (occasional field) archer who loves supporting innovative businesses not want to shoot a CV9???
@@CaraVanOlogywithBecky we have several full Oly style customers who shoot CV9s. We also have customers who fully understand biomechnaics and understand that a front end loaded DFC can deliver better performance for less holding weight and less fatigue. The DFC though for heavily ingrained draw cycles takes a lot of getting used to, but doesn't mean it can't achieve. The market is also heavily dependent on sponsered shooters and retailers who have a dog in thr fight which is like swimming against the tide. So to provide product for market sectors helps customers decide which limb to choose. I'm not saying we agree fully with the market sectors we put out limbs in, customers new to us, haven't a clue what all this means. Afterall, we have had several decades of limbs getting smoother. Yet not actually producing any evidence or data to show smoother. We can and do! Most folks don't understand that part. Does that answer your question?
❤👏👏👏👍🙋🏻♂️
The details you explain in this video about stack has me finally understanding what the hell it is! I started building bows, just learning by trial and error (practically all errors at this point), but without understanding how it works, I can't hope to get better
I've really been enjoying these videos. I'm a fairly new bowyer, and I've been trying to chase performance, through design and improving my materials. In the USA you are correct that there are only 2 glass manufacturers that are available and it can be hard to find information about other materials.
So is it better to have the pivot point in the centre of the riser?
Epoxy glue is a subtype of epoxy resin.😊 So limbs are made with prepreg, not already cured composite laminate... Fascinating🤩 Did you tried phenol formaldehyde based prepreg instead of epoxy based one?
@@dmitryantonov2862 I never say what we use. I only state normal carbon processes. Layers of material held togther with resin, is still layers. Layers are subject to delaminations
Fascinating stuff Sid. Beautiful range you got there as well.
Great videos!You got a new sub...
You are one of the very few who says anything about archery that makes any sense.
Vidéo intéressante, pour tous les tireur classique est barebow
I don’t always trust carbon materials in the past I was into fly fishing for salmon and I had two fly rods snap while casting. I never had a fibre glass rod snap. With regards to archery I use fibreglass laminate with maple limbs. I suppose I’m a cheapskate old fart who only shoots in the back garden at 20 yards so cheap limbs are more than adequate for my use. I find this video very informative, cheers.
@@peterreece6547 there are considerable performance benefits with carbon, and being cheap with the handling DOESNT pay off and price doesn't reflect your duediligance in materials handling
I would have thought that deflex should be considered a ratio of riser length to pocket line/throat depth. Isn't what we are interested in is the pocket-throat-pocket angle? It seems to me that a 68.58 cm (27") riser with a 3.5 cm depth has the same deflex as a 48.26 cm (19") riser with a 2.46 cm depth with the pocket-throat-pocket angle for both at 168°?
@@buzzhooker8398 what does that relationship establish? What would be the reason for that angle? What does deflex do? And therefor what would that angle vs default value achieve to accomplished this?
Really cool 😎👍💯🔥
Just make a weighted arm guard : it does the same thing. It's on you not the bow. A fat beer gut is also a big stabilizer, go figure?
Fullcarbonlaminated maybe?
I think epoxy resin and epoxy glue are the same thing and yes, that’s laminated, what you did there. I’m not sure where you were going with this, but I’d assume that pre-preg would be superior material to work with as it minimize the possibility of too much resin in the layup (the resin itself isn’t the strength so much as the fibers and their interconnection is) as well as inadequate saturation of the resin into the fibers. Not saying that you have to use pre-preg to get the best product, but I’d think it sure makes things easier and more consistent.
They claim that chemical bond is stronger than mechanical, chemical bond means that you saturate fiberglass/carbon cloth in resin and laminate it together in one shot, and mechanical bond means that you use cured products and laminate that together… Personally when i have bow delaminate it is usually wooden bow core that fails, never had actual glue fail. I don’t think that chemical bond is much stronger than regular mechanical bond as they claim…
you need to work on your website and bow ordering procedures ,I had $3000 Aus to spend on one of your bows but got no response
@@bahbahblacksheep9373 who did you contact?
I would think glue and resin are two different things 🏹
vary good video like always thank 🤠
There are a lot of sketchy manufacturers in third world countries producing a cheap product. Maybe you get what you pay for. Often, paying for quality is cheaper in n the long run.

Border should offer these limbs.
What speeds are you getting out of your bows? Would love to see a video on this too. Perhaps you've got one that I did not find? 😄
@@kviljo we don't trust chrono results. Be it ours or yours. So how would we have faith that your results marry ours.... lets say there are chronos that run 10fps different to others. So your expectations are based on what datum speed.....
@@BorderArcheryLTD For sure! There are too many variables to compare tests from different test setups, but it would be cool to see your bows against other brands, if you've got the time to test them. I plan on doing the same, but haven't yet found the time yet.
@@kviljo would you trust a manufacturer to test 2 bows, there's against?? I don't even trust independent testers. I "broke" a tester when I said a hootereshooter doesn't test trad bows well, as you don't shoot the bow with your hand pressure dead in the throat, so tiller is off.
@@BorderArcheryLTD One could always find excuses not to trust results, but there are certainly ways of making a test pretty objective. I think it would have been interesting to see. You must have tested the speeds of your bows yourself? 😄
And can't you make it by attaching a layer of wood on top of carbon? Since it is a traditional bow, I think it would be more suitable to have a tree feel.
@@파닥파닥물고기 we don't use any glass fiber. Our limbs are not glass limbs marketed at carbon limbs. They are genuinely carbon. And carbon only comes in black. So afraid not
