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.

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

Cool. Thanks for sharing.

Great video. As always thanks for sharing your knowledge.

Now get WA accept this in the Traditional class, PLEASE

Thanks

Checkout this new metal coating technology would this help with bows. th-cam.com/video/ZpEinrBmgXs/w-d-xo.htmlsi=mCUoXT8SxBXmSUg-

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.

Thank you for that , Cheers from Ayrshire

I thought it was more to do with draw length than anything else

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.

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.

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.

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.

Would the lightest bow possible for a given draw weight be a recurve or an RD longbow?

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???

❤👏👏👏👍🙋🏻‍♂️

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?

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.

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°?

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

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.

good video ur so dam smart thank so much and god bless you and ur family 🤠👍

good video thanks so cool🤠👍

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? 😄

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.

I am a Korean archer who has been interested in Covert Hunter for a long time. We also have a dealer in Korea. If there is a request to make the tip wooden, could you accept it?

Which of these is closest to the older vx+ uukha limbs?

Here you have an expert explaining very! Interesting bow-technical stuff :) … and myself as an amateur-scientist with autistic tendencies getting all confused by the use of turns,twists, …-words. I’ll have to look this through more then once to be able to understand what mr Border is talking about. Vertical tension on the limb .. and then showing an horizontal movement … ? Confusing for me :)
