    Looking for crossbow makers

    Post by OverlyComplicatedGag on Fri Mar 08, 2013 3:07 pm

    I'd love to start emulating all the awesome examples I see here and start building my own crossbows. I thought it would be best to start by buying one as an example/inspiration. I also kind of have a thing for wood and natural materials.

    So far I've sent some queries to Slobows, New World Arbalest and jr-binks (on eBay).

    I'm looking for a slurbow, to shoot 1/2-inch ball bearings at targets and varmints. It will see regular and fairly heavy use. I'm hoping for a steel prod, roller-nut release with modern trigger and ~125-150# draw. I'm willing to take suggestions on these details, however.

    Thanks!

    Do you want a Stone Bow or a Slurbow?

    Slurbows were not normally 'bullet' shooters, but rather threw unfletched bolts or specially fluted bolts. Stone Bows threw stones/balls/ pellets. See Payne-Gallwey The Crossbow Book Chapter 29 (Slurbow) and Chapter 33 & 34 (Stone Bows) Here: http://www.crossbowbook.com

    While the Slurbow could have used a roller-nut lock, the Stone Bow usually did not. Since you want a modern trigger rather than a tickler, there are other mechanisms that might be more efficient.

    I am aware of the normal distinctions, but there are some examples of bullet-shooting slurbows. I'm also sick of damaging/losing arrows with my handbow and figure that ball bearings are more readily-replaced, for much cheaper per shot.

    I'm open to suggestions on the trigger mechanism. What are some examples that would be more efficient?

    Thanks!

    Look at Figures 108 & 109 in The Crossbow book. That action even has a set trigger. Also search here; I've seen a number of efficient trigger actions sketched and built.

    You will not be disappointed by pursuing the accuracy
    challenge and economy of operation with the bullet type. The only thing I know
    about slurbows is they work with special fluted darts. I imagine the use of
    balls, relying on the loose fit in a barrel would give BB gun accuracy. The
    most relatively common bullet bows are double string type of 18 thru 19 century
    British make.



    I am also a beginner with crossbows but, but I have experimented
    shooting thousands of steel and lead balls through a dedicated single string
    bullet crossbow of my own design. The lock is a tickler type but incorporates
    an automatic safety which also proves a visual indication that the weapon is
    completely locked and safe. This type of trigger is very smooth but also has a
    long travel. My next may have a double set trigger. I use a homemade bullet trap “stand” to
    recycle the balls. The .375 ball bearings have given 5 shot groups of a bit more than
    3/4”at 60 ft. It works so well that I believe the spread is my undoing not the
    crossbow! The surprising accuracy is mainly due to the track profile and bullet
    holder which fit intimately with absolutely no play throughout the power
    stroke, my avatar shows a cross section. The sights alternate between both
    homemade front/rear aperture and inexpensive 4 x 15 scope. Now that I am
    satisfied with months of changes I started finish shaping the tiller today.

    Hm. I wonder if a snugly-fitting "barrel" on a slurbow-type bullet-shooter would increase accuracy. I've seen some sporting examples that had pretty long, extended "barrels" past the prod (I think they were spanned with a goatsfoot lever, since a stirrup would be problematic to say the least).

    Thanks for all the suggestions about triggers, by the way.

    So far I've only heard back from an eBay seller (Jr-binks), and he's only willing to make a lifting-peg trigger. On the other hand, he claims pretty good accuracy with his slurbows so far (shooting .44 ball bearings).

    I'm specifically trying to avoid a stonebow-design since I've seen quite a few grips on this forum and elsewhere about fitting a double-string to it.
