    Nuts&Bolts - OK Archery DST 40...preview of my review

    Ok folks.

    Here is a PREVIEW of my RE-VIEW.

    I have some new stabilizer parts coming, and they have not arrived yet.

    So,
    he is a PRE-View of my RE-View.

    Spent most of today checking out the DST 40.
    Chris at OK Archery made me the "SPEED DEMON" version,
    so we're talking the smaller cams with modified limb pockets
    to get me to the 27.25-inch TRUE DL, which translates to 29.0-inches of AMO DL.

    Most European bows are sold based on TRUE DL, which is 1.75-inches LESS than AMO DL.

    Slapped the bow on the draw board, to check:

    a) draw length setting.....DEAD ON PERFECT, straight from the factory.
    b) cam sync.................DEAD ON PERFECT, straight from the factory.



    Fired several shots.

    ZING. ZAP. WHOOSH.
    The bow draws/builds/hits peak draw weight EARLY.
    Limbs are parallel and pre-loaded.

    Holds peak draw weight for a long long time, and then free falls into the wall/holding weight.
    This was with the stock cam timing (factory cam starting rotation position).

    WOWSER.

    No chrono work yet. Gotta build a proper chrono lighting system, first.


    Sooooooooo,
    started tweaking the cam timing
    (went a skosh longer on the buss cable)
    (went significantly shorter on the bowstring twists).

    Much smoother draw cycle.

    When I get to the full blow tech review,
    I will do a Draw Force Curve for the way I like to shoot the draw cycle
    and
    I will do a Draw Force Curve, bone stock, as delivered in the box.


    So,
    a few pics,
    of course.





    This is the ABSOLUTE FIRST bow,
    I have been able to take a bareshaft and SPLIT the bowstring,
    shooting at 3-yards, ish.




    For now,
    custom modified Paradigm String Supressor...
    front stabilizer bushing (not a Quick Disconnect) to protect the front stabilizer threads in the riser
    Doinker Platinum Hi-Mod front stabilizer.


    A PROPER review to follow later.

    Nuts & Bolts I'd like to hear why you use the string technique as well when you get the full write up. Looking forward to it!

    Doesnt surprise me. Everyone that has shot mine has been dead on shooting it. Actually most shoot it better than me.

    First thing most comment on is how its balanced and holds on target.

    Been looking forward to your review.

    The DST 40 is a semi-custom build.
    I requested the smaller cam design for speed,
    at a 29-inch draw length,
    so Chris at OK Archery used a slightly different limb pocket to get to
    the 29-inch AMO draw length.

    So,
    as delivered from the factory,
    straight out of the box....

    the cam timing position (starting rotation position)
    had a very aggressive draw cycle. I'm keeping notes,
    as I tweak the timing, to get a smoother draw cycle.

    Chris at OK Archery warned me that this "speed combo" was going to be aggressive
    where as his larger cam designs are smoother, by design.

    So,
    I'm running experiments, tuning by FEEL only...no draw force curves, yet.

    When I find the "right balance", find the final sweet spot for cam rotation position..

    then,
    I run a draw force curve for the "tweaked spec" version
    and
    run a draw force curve for the "factory spec" version.

    The factory spec version is aggressive...
    builds up to peak weight very quickly,
    long flat plateau at peak draw weight,
    and then drops/ramps down quickly to holding weight.

    I think he meant why you use the string to tune as opposed to paper, walkback, etc.

    Alan,

    Sweet bow! The design has to be the easiest to tune on the market!

    Like I have been saying...OK Archery is the World's best Compound Bow. You really should treat yourself to one.

    Alan, OK Archery is the only manufacturer I know that uses true DL.
    Hoyt, Mathews, Bowtech, Martin, Elite etc. are sold based on AMO DL same as in the states.

    Hello Felix:

    Barnsdale bows are sold based on "true draw length....or 1.75-inches LESS than AMO draw length.

    Merlin, based in the UK,
    also sells bows based on True Draw Length.

    Haven't tuned for centershot or group tuned yet.
    Just started in the garage this weekend,
    to do the very very initial steps.

    Shooting at a string at 3 yards,
    with a fletched and a bareshaft is to get a rough idea
    for centershot (basically dead center) and sight windage
    since this is a shoot thru system.


    Later,
    when I get to the practice range or indoor range,
    I can do MODIFIED french tuning, to confirm these initial rough settings.

    I usually tune for cam sync at 20 yards, with bareshaft and fletched.
    Have not gotten to that step yet.

    Just reporting on the draw cycle, in this PRE-View of my RE-View.

    Allen, Dean and myself was able to get that kind of results with a Bowplane tool. Not hard to set centershot at all on these bows. Honestly think I could have eyeballed it. But the Bowplane tool dont lie.

    Did you measure the brace heigth?

    WOW Alan, sounding pretty good so far. Will be waiting for the full review.


    Skeet.
    I cut my arrows twice and they're still too short.

    I didn't know about Merlin.
    What I was saying is that here in Europe we don't recalculate the DL on the US made bows.
    We are pretty used to work with AMO DL.

    Adjusting the string length is rotating the starting position of the cams and changing the draw cycle. Not tuning the bow.


    Man o man I really want to shoot one of these bows.

    I know what you mean.

    I was working with a fella couple of years back.
    He had purchased a used Barnsdale.

    Took me a while to figure out,
    that,
    when we were done,
    tweaking form and draw length...

    the "best" draw length for him,
    turned out to be EXACTLY 1.75-inches shorter.

    Hello DB:

    I'm tweaking to get the FEEL that I like.
    Just spoke/wrote with Chris at OK Archery,
    and
    I have some more ideas I want to try.

    Of course, I am documenting all changes to the rigging,
    so I can get back to the factory spec,
    as delivered out of the box.

    Out of the box,
    I can feel that the draw force curve is VERY aggressive,
    it hits peak draw weight very early.

    I will put all the numbers and graphs in the FULL tech and photo review...later.

    You cams are diffiantly more aggressive than mine. Mine draw smooth and have little break over at the end. Im sure there nothing like you speed cams. I dont know much more one could do to these bows in adjustment. Easiest bow I have ever tuned. Believe my brace heigth is 8.2" and yours is around 7". Just wait untill your sighted in, warning dont shoot groups.
