Face or back

[Roy from Pa]

And this is why I make BBO bows and some guys make selfbows.

I wonder if the native Americans sat around the tee pee bickering about who had the fastest bow?

But I understand where ya all are coming from.

[Shredd]

   Roy I personally have not bickered once over bow speeds...  I can't ever remember any two people fighting over who had the faster bow...  You either do or you don't... I think these things are created in people's minds because of ego and the basis of competition of who can be the fastest and the fear of losing that competition and/or the fear of feeling inferior of someone with a faster bow... Let's face it... No one shoots to build the slowest bow they can make...  Some people fear competition, some people embrace it, there are good losers and there are sore losers and some just don't give a chit either way... In surfing we call them soul surfers...  I personally don't give a chit, I just always liked seeing how far I could wind up that clock before it would break... That's my high... I think if I had to make a hundred bows and I did not try to make them the best performing I think I would get bored and quit or make each bow unique and purty...
   This speed thing sometimes gets a bad rap...  But some of the same guys talking chit about speed are shooting 65# bows... I would like them to explain that being a 40# bow can take down most game in the US...  The only people I hear bickering or complaining about speed are the people that shoot slower bows...  Maybe they feel they have to prove something...
  I enjoy the challenge of making a fast bow just as much as you enjoy the challenge of making a wood one... We don't all have to be an Indian or think like one to get the pleasures of how we want to make a bow...
   There are advantages to a fast bow... Smoother draw and less stacking run hand in hand with a fast bow and you can't beat a flatter trajectory...

    I guess the bottom line is some like plinking with a 22 lr and some like a 223...  It's no really big deal... It's what you like and you choose...  But don't get down on other people for having their fun...

Hey maybe dem Indians making stick bows bitched about the ones using horn and sinew...

 Bue my new design is even faster shooting 192 to 193 @ 10 gpp @ 28" @ 7" brace...  That bow on Tradlab is fastest in my class amongst trad f/g bows and placed 4th overall amongst the carbon fiber ILF's just 1 fps behind Border...  The fastest was Uukha at 196...

  I have not sent my new design to Tradlab yet because it is a new design with only 5 bows made so far... I want to tweak it to hit 195 or higher...  I am shooting to be first overall and with a simple maple / f/g layup...  May have to go to carbon to get those last few fps... 

   I am not trying to be a jerk or wanting to put a damper on these high tech discussions, I like the discussions to some degree but there comes a point where you draw the line between talk and actual real testing... That's where real progress is made... I am just trying to push some of you in the right direction...   I constantly hear talk but I am not seeing any bows... Bows with numbers pushing the limits... I am not seeing any real numbers that matter, like string tension percentages, dfc's, arrow speeds, angles, radius's, ect....

   I hope some of this hits home with you all and gets you in the right direction towards performance, if that's what you are really seeking...

   Wishing the best for you all...

LOL

Relax Rich, I said I understand guys wanting faster bows.

It's just not my thing, I'm happy for you that's it's your thing.

I tried making one glass bow, it wasn't the same as carving one out of Osage and boo, so I didn't like it.

The only thing those fast bows do is miss faster:)

[Shredd]

 I'm chill bro...    I knew what you said... I was just getting my thoughts across...   Words don't tell how a person is feeling and most was not directed at you... But trust me I am chill about it all... I was speaking in general to the crowds and airing my views and thoughts...

  By the way I would love to have one of your bows one day... Maybe we can do a trade off if you think you can handle the heat...   

A fast bow with a very flat trajectory is least likely to miss...   

[Roy from Pa]

We can work on that someday.

[Shredd]

Sweet... You know I gots family in Pa... I can swing out that way and we can chew the fat...

[Roy from Pa]

 

[kennym]

Rich, he will lead ya astray...  You'll be covered in yellar sawdust and stuff..

[Roy from Pa]

Be better than itchy gwass:)

[Shredd]

   Kenny, I know... I'm a bit scared... I hear he snorts the stuff...

I see a market for "Magic Lams" in the future.


"Do the materials we use store more energy and return to their resting position faster, when in tension or compression?

For linear elastic materials they will store the same energy either way. I don't know if our composite lams behave close enough to linear elastic or not for that to work. Gordon's published info says their lams have the same elastic modulus in both tension and compression, which indicates they are very close to linear elastic behaviour.

Also worth noting is that Gordon's lists the tensile strength of the ULS lams as 152,000psi and the compressive strength as 119,000psi. The UL lams have a tensile strength of 152,000psi and a compressive strength of 111,000psi.

Good question on the rebound back to shape."

The original question was not material specific. What about the other components? We are not building exclusively fiberglass bows. The downside of linear thinking, is all the important factors left in the wake of a myopic goal.



"Do we try to establish the position of the neutral zone or do we leave it to destiny? 

The neutral axis is easily calculated for any given cross section shape. You certainly don't need to know what it is to build a bow, but understanding its effects and controlling where it is located are useful things when trying to maximize performance."



That is called tongue in cheek (joke)

[Roy from Pa]

Has anyone every talked to a neutral plane and asked it what it thought?

[Mad Max]

Some people like Drag racing, ME
And some people like Horse and buggy racing, Not me.

Nice work shredd

[Flem]

Has anyone every talked to a neutral plane and asked it what it thought?

It's indifferent, happy to go with the flow. And since its intangible, hard to pin down.

[Roy from Pa]

Can a homogeneous neutral plane, glued between two surfaces, react like a true conceptual neutral plane?

Think I'm off the PC for a while here.

Gonna go put a fire in the bow shop wood burner and get it warm out there and clean up the basement after painting a wall.

28 degrees and snowing here, supposed to snow the next 3 days cause it's January in Pa.

And I love it just like it is:)

[Mad Max]

quote roy "Has anyone every talked to a neutral plane and asked it what it thought?"

I did, I told it I was going to stretch it and glue 1 piece of glass to it with alot of reflex.




Now the neutral zone is compressed

Then I told it to get on that form so I could glue the second glass to it, but it jumped off and fell in  the floor, true story


when I pulled it off the form it sprung in, not out.
this is how much it sprung in


Something to think about

What do you think this would do?????????????????????

[Stagmitis]

Max if you cut that in half and used green glass Will Ferrell would be proud 

[Roy from Pa]

Max are you making a boomerang?
