• A modern invention

    From Technobarbarian@21:1/5 to All on Fri Jun 17 13:44:29 2022
    Catmobile's latest thread reminds me of a very simple recent
    invention that I recently figured out I had paid for.

    When I got into archery I did a lot of reading to figure out what
    would be the best bow for me, because I knew very little about it. I
    ended up buying the least expensive compound bow Bowtech puts their name
    on because it's considered a good beginner bow. Shit, it's a great
    beginner bow and I don't think I'll ever outgrow it. Part of what makes
    it a good bow for beginners is that it has "binary cams". Compound bows themselves are a fairly recent invention. Binary cams are even newer and
    it is about the simplest invention you can imagine. The bow string I
    pull is connected directly to both cams. That's it. That is the
    invention. Binary cams are all over the place now, but look what happened.

    https://en.wikipedia.org/wiki/Binary_cam#:~:text=The%20binary%20cam%20is%20a,design%20on%20December%2011%2C%202007.

    "The binary cam is described as a modified twin cam setup where each cam
    is slaved to the other via a loop of string connecting the two cams.
    This is contrasted with a typical twin cam setup where the ends of the bowstring are physically anchored onto each of the bow limbs.

    As a twin cam system relies on each cam rotating independently, based
    solely on the force of the string and the resistance of the bow limbs
    being absolutely symmetrical, there is room for a twin cam system to
    "lose tune" [4] through wear and tear, string stretch, or just general
    age. The effect of a detuned twin cam bow is that the two cams rotate
    out of sync with each other, causing the bowstring to accelerate in two alternating directions upon release. This causes a number of adverse consequences, the most obvious being unsteady arrow flight.

    The binary cam overcomes this by 'slaving' each cam to the other; as one
    cam is unable to rotate without the direct equivalent action of the
    other, the two rotate in near perfect synchronization, with any possible differences in rotation automatically correcting themselves as the shot
    cycle is completed. In effect, a binary cam bow never needs cam-timing tuning,[5] whereas a high end twin cam equivalent might need it done as
    often as every few months in order to maintain critical accuracy.
    Bowtech pays Rex Darlington of Darton Archery royalties for use of this
    cam design."

    "Types Of Compound Bows"

    "Binary Cam Compound Bows
    The fourth type of compound bows are binary cams and these are a further development from hybrid cam bows. In a binary cam compound bow, there
    are two active cams just like in a dual-cam setup.

    The cable from the two cams go to the opposite cam. This means the cable
    from the top cam gets attached to the lower cam while the cable from the
    lower cam gets attached to the upper cam.

    Such an arrangement makes both cams depend on the movements of each
    other, producing an entirely different dynamic from the other compound bows.

    Binary cam bows generate plenty of power for high-speed arrows and the
    two cams regulate each other. Any imperfections in their limbs get
    smoothed out for clean and accurate arrow releases.

    Advantages of binary cam compound bows.

    They have high power & speed. Unlike hybrid cam bows, binary bows have
    two power cams which helps to produce more power and more draw weight.
    This advantage means faster arrows.

    They are built to have high precision. The unique cam configuration of
    binary cam bows makes them self-balancing and therefore reduces any nock
    travel issues.

    This makes the binary cam compound bow the most precise compound bow.
    The technology of bows is always getting better and this makes our sport
    more exciting than ever.

    Disadvantages of binary cam compound bows.

    Some patent issues have halted many manufacturers from marketing their
    binary cam compound bows as such.

    They sell their binary bows as hybrid bows, although the technology is
    actually binary, they label them as hybrid-bows to avoid legality problems.

    Also their highly complex design translates to frequent maintenance and tuning."

    https://archerysupport.com/types-of-compound-bows/

    With modern strings the only maintenance my bow needs is to have
    new strings installed every two or three years and I put a little wax on
    them every now and then. My bow is more accurate than me and probably
    always will be.

    (On a side note: I saw a guy out at the club with a bow that has
    four cams instead of the usual two. It's a dual binary cam system. The
    four strings meet in one string that the archer pulls. If you're really
    good at tuning it might be slightly more accurate than a conventional bow--maybe. The guy who was using it works for the company that makes it.)

    That's all very interesting, but at the end of the day going forward,
    I allege that you're going to make a lot of people uncomfortable by
    your persistent and gratuitous use of "slaved". Some influencer on megafacebutt with 627,453 loyal followers is going to get offended,
    and your sorry ass is going to become persona non grata in a wide geoideological social venue. I mean, c'mon man - I'm not joking - when
    every dumbass thing is on the table, you gotta literally be
    circumspect if you expect to not be held accountable for your
    inefficacious and outrageous and unacceptable insensitivity. Not only
    that, but "binary" could also maybe conceivably possibly enter into
    the calculus and also bite you in the ass and cause your excretion
    metrics to evolve in an unanticipated and undesirable direction.

    Archery has advanced a ton since I was shooting. My first compound was
    a TSS Quadraflex in '89. In 1991 I bought a "Royal Hunter" from High
    Country Archery in Idaho. I sold both bows and all my old archery
    equipment earlier this year.

    It would be fun to swap stories about archery sometime. For the 4 or 5
    years I was into archery I was loosing at least a hundred arrows a day
    and often more. We had a ton of fun and even did some bowfishing for
    carp (not the bfh carp kind) in eastern Washington.

    I'll bet you cheated and took advantage of the poor disadvantaged carp
    by using polarized sunglasses. And I'll allege that the poor carp was
    probably under 24 years old - just a child. Was it also a mass
    arrowing? Did you frighten 4 or more?

    I'm strictly a duffer. What little stories I have are about the pleasantly odd people you meet at the club. One of the nice things about shooting out there is that most of the time someone will eventually find
    your lost arrows and toss them in the arrow bucket. Last time out I
    found one in the bucket and lost one.

    Compound bows themselves are a fairly recent invention. Binary cams
    are even newer and it is about the simplest invention you can
    imagine. The bow string I pull is connected directly to both cams.
    That's it. That is the invention. Binary cams are all over the place
    now, but look what happened.

    https://en.wikipedia.org/wiki/Binary_cam#:~:text=The%20binary%20cam%20is%20a,design%20on%20December%2011%2C%202007.


    "The binary cam is described as a modified twin cam setup where each
    cam is slaved to the other via a loop of string connecting the two
    cams. This is contrasted with a typical twin cam setup where the ends
    of the bowstring are physically anchored onto each of the bow limbs.

    As a twin cam system relies on each cam rotating independently, based
    solely on the force of the string and the resistance of the bow limbs
    being absolutely symmetrical, there is room for a twin cam system to
    "lose tune" [4] through wear and tear, string stretch, or just
    general age. The effect of a detuned twin cam bow is that the two
    cams rotate out of sync with each other, causing the bowstring to
    accelerate in two alternating directions upon release. This causes a
    number of adverse consequences, the most obvious being unsteady arrow
    flight.

    The binary cam overcomes this by 'slaving' each cam to the other; as
    one cam is unable to rotate without the direct equivalent action of
    the other, the two rotate in near perfect synchronization, with any
    possible differences in rotation automatically correcting themselves
    as the shot cycle is completed. In effect, a binary cam bow never
    needs cam-timing tuning,[5] whereas a high end twin cam equivalent
    might need it done as often as every few months in order to maintain
    critical accuracy. Bowtech pays Rex Darlington of Darton Archery
    royalties for use of this cam design."

    "Types Of Compound Bows"

    "Binary Cam Compound Bows
    The fourth type of compound bows are binary cams and these are a
    further development from hybrid cam bows. In a binary cam compound
    bow, there are two active cams just like in a dual-cam setup.

    The cable from the two cams go to the opposite cam. This means the
    cable from the top cam gets attached to the lower cam while the cable
    from the lower cam gets attached to the upper cam.

    Such an arrangement makes both cams depend on the movements of each
    other, producing an entirely different dynamic from the other
    compound bows.

    Binary cam bows generate plenty of power for high-speed arrows and
    the two cams regulate each other. Any imperfections in their limbs
    get smoothed out for clean and accurate arrow releases.

    Advantages of binary cam compound bows.

    They have high power & speed. Unlike hybrid cam bows, binary bows
    have two power cams which helps to produce more power and more draw
    weight. This advantage means faster arrows.

    They are built to have high precision. The unique cam configuration
    of binary cam bows makes them self-balancing and therefore reduces
    any nock travel issues.

    This makes the binary cam compound bow the most precise compound bow.
    The technology of bows is always getting better and this makes our
    sport more exciting than ever.

    Disadvantages of binary cam compound bows.

    Some patent issues have halted many manufacturers from marketing
    their binary cam compound bows as such.

    They sell their binary bows as hybrid bows, although the technology
    is actually binary, they label them as hybrid-bows to avoid legality
    problems.

    Also their highly complex design translates to frequent maintenance
    and tuning."

    https://archerysupport.com/types-of-compound-bows/

     Â Â Â Â Â  With modern strings the only maintenance my bow needs is
    to have new strings installed every two or three years and I put a
    little wax on them every now and then. My bow is more accurate than
    me and probably always will be.

     Â Â Â  (On a side note: I saw a guy out at the club with a bow that >>> has four cams instead of the usual two. It's a dual binary cam
    system. The four strings meet in one string that the archer pulls. If
    you're really good at tuning it might be slightly more accurate than
    a conventional bow--maybe. The guy who was using it works for the
    company that makes it.)

    TB

    Archery has advanced a ton since I was shooting. My first compound was
    a TSS Quadraflex in '89. In 1991 I bought a "Royal Hunter" from High
    Country Archery in Idaho. I sold both bows and all my old archery
    equipment earlier this year.

    It would be fun to swap stories about archery sometime. For the 4 or 5
    years I was into archery I was loosing at least a hundred arrows a day
    and often more. We had a ton of fun and even did some bowfishing for
    carp (not the bfh carp kind) in eastern Washington.

    I'll bet you cheated and took advantage of the poor disadvantaged carp
    by using polarized sunglasses. And I'll allege that the poor carp was probably under 24 years old - just a child. Was it also a mass arrowing?
    Did you frighten 4 or more?

    Quit fishing for compliments, you piker.

    That's all very interesting, but at the end of the day going forward, I allege that you're going to make a lot of people uncomfortable by your persistent and gratuitous use of "slaved". Some influencer on
    megafacebutt with 627,453 loyal followers is going to get offended, and
    your sorry ass is going to become persona non grata in a wide
    geoideological social venue. I mean, c'mon man - I'm not joking - when
    every dumbass thing is on the table, you gotta literally be circumspect
    if you expect to not be held accountable for your inefficacious and outrageous and unacceptable insensitivity. Not only that, but "binary"
    could also maybe conceivably possibly enter into the calculus and also
    bite you in the ass and cause your excretion metrics to evolve in an unanticipated and undesirable direction.


    Yeah, I've seen some of that buzz over the years. So I got to
    wondering about the possible alternatives. They stink. They're generally ambiguous about the relationship between the various devices. I
    particularly object to "follower" instead of slave, because this implies
    the follower has a choice. This usually isn't the case. I certainly
    don't want my cams wandering all over the place.

    Personally I don't think slave is all *that* racial. The practice
    has been pretty widespread. I don't think there's any race that hasn't
    had some people enslaved. Americans don't seem to discriminate much in
    the people they enslave. There have been times when it was somewhat
    common for people to sell their children in this country. There were
    still open markets for Native Americans after the Civil War.

    https://www.allaboutcircuits.com/news/how-master-slave-terminology-reexamined-in-electrical-engineering/

    "A Change in Terminology May Require Steep Adjustments"

    So far 'binary' seems to be safe. I have met people who describe
    their orientation as "non-binary", which I think is nicely
    self-explanatory, without going into details you really don't need.

    Don't even get me started on the use of male and female for
    various connectors.

    "The terms plug, pin, and prong are also often used for "male"
    connectors, and receptacle, socket, and slot are used for "female"
    connectors."

    Oh please, these people have no appreciation for the human love of euphemisms. The difference between prong and slot and the usual terms
    escapes. If anything they could be considered a bit more crude.

    https://en.wikipedia.org/wiki/Gender_of_connectors_and_fasteners#:~:text=The%20terms%20plug%2C%20pin%2C%20and,used%20for%20%22female%22%20connectors.


    Personally I don't worry much about this stuff. I figure that when
    I use old terminology people will think it's because I'm old and stuck
    in my ways instead of just plain rude.

    I stopped shooting years ago, but I and my friends were a little more traditonal. As in Flat, Long or Recurve with a few going as far
    traditional (not modern) composite


    I enjoy watching the competitive recurve people practicing at 60
    yards and more. My wife is using a modern recurve bow. I'm more of an
    instant gratification type. I got into archery from an odd angle. For
    the last 15 years I was mostly working in consumer electronics. Some of
    the clients were major players in the video game business. I started
    playing video games so I knew what I was talking about. The gamers are impressed when an old guy can speak their language, instead of saying
    you don't play video games like it's some sort of sin. I heard *that* frequently. My favorite was role playing games and I liked long distance weapons. I figured that if I ended up going toe to toe with some
    electronic monster I had already made a serious mistake. So I frequently
    ended up with an electronic bow, or some sort of plasma weapon.

    When we moved here we ended up within easy walking distance of an excellent archery shop. Eventually I got curious and we took their basic introductory course. When we found out about the local archery club that
    sealed the deal. It's a beautiful facility and membership costs less
    than what we spend on arrows.

    I'm strictly a recreational archer. The only person I compete
    against is myself. I thought I might want to hunt with my bow until I
    found out that my Sister and her husband are willing and able to supply
    me with all the elk meat we can eat, already cut and wrapped. We eat elk
    like it's beef and I don't buy much beef. The club has 5 field courses
    that are nicely shaded by trees that are almost 90 years old. The Oregon
    fish and game commission helped pay for a cover over the shooting area
    on the target course. This makes it a nice way for an old duffer to get
    some exercise.

    I was an avid bowhunter, back in the day, though I never really damaged
    the game populations much. A friend and I used to practice archery daily
    and we enjoyed going to archery shoots with 3-D targets. One shoot had a prize wheel set up. They had a 5 foot diameter plywood wheel that
    rotated. They placed straw bales in front of the target such that, from
    the shooting line 35 yards away, you could only see the top half of the
    wheel as it rotated.

    On the wheel they had 2 inch round colored stickers with a prize written
    on each sticker. The prizes were things like broadheads and bowstrings.
    They also had 12 packs of beer and the top prizes were a couple of nice
    Old Timer knives. They charged $3 for three chances to shoot at the
    wheel. I paid my money and my last arrow was touching one of the prizes
    but they wouldn't give it to me 'cause they said my arrow hadn't broken
    the edge of the sticker - only bent it. I said, OK, and paid them for 3
    more tries. This time I took both of the knives and one of the beer boxes.

    The trick was, and I don't know if they realized it, but the wheel
    rotated at a constant speed. Once you knew which stickers had which
    prizes on them it was a simple matter to pick a spot just above the bale
    and wait for the sticker to rotate down to it. Then, it was just a
    simple matter of timing the arrow flight and hitting your spot.

    I gave one of the knives to my friend and we drank the beer back at our campsite. I still have the other knife.


    In Ye Olde Nottingham, you would have won the hand of Maid Marion, in marriage, for such marksmanship... It still was certainly a victory for archers these days...
