    after some time past with others projects I am back to rubber powered crossbow . This time we can say :pistol or short crossbow. The setting is still inswinger but lighter as possible end bull-pup configuration. First picture is the trigger mechanism. All the metal part are aluminium for the weight end the ease of work.[img][/img]inswinger :evolution still rubber powered Img_0010

    I used a bench-test whit a limited power , it work well . It won't need a lot of power to to be very fast . I use spruce for the body and cherry for the stock. Expendable cheep internet bolt, I will try also short pistol bolt even cheaper.

    It got sliding stock, the balance is exactly at the handle. It is around 3 pounds it can be shot like a pistol stock folded,or like a short carbine extended stock.

    Awesome. Do you use ball bearings for the levers ?

    I like it, if you added 4 more pulleys onto the front , two parallel to the rear and 2 on a 45* angle, you could make it powered by a compression spring underneath the forend stock, albeit, you'd have to make the limbs steel as aluminum would surely bend after repeated firings.But I like this one, gives me inspiration to start a project!

    Why not check out "Woodland survival flipper" on youtube? Between that and everything here on the guild, you ought to be able to get some inspiration and design help.

    Link to a real torsion "ballista" made by NIck Watts. Awesome.

    Taking on the flipper setup,ey? Very Happy

    Looks great Jeep. As always lots of nice little details!

    How do you like the roller trigger so far? Run into any problems...softie aluminum and all?

    The setting of this mechanism is not to complicate as soon you make all the piercing at the right level. The use of aluminium is very convenient as matter of facility of work . It is OK if the pull-weight is not tremendous. All the system can wok with only one spring.On this model I use rubber as spring:cheap, powerful, easy to replace. If you look carefully it is more an evolution of my first inswinger then a simple flipper, all ropes anchor and pulley are at different places, and the rubbers setting are inspired by OSS little Joe pistol. Each little rubber ring are folded by two, that give a full efficiency for a shorter draw.

    You are certainly right but more pulley = more friction , more weight. Steel spring are perfect but heavy and slow and as you say need re-enforcement, use of steel add weight so = wast of power .Why not but is not my favourite option.

    No ball bearing, to complicate, simple washer fit very well if the levers are very lightly tight.

    I see , you make a good point, I've been wondering how a steel string would react to aluminum trigger components wear and tear wise.

    Hello Jeep



    I love a lot your inswinger weapon...Is the correct name? Well, please tell me how long a short pistol bolt dart goes when you fire your exceptional well done prototype flipper. You know I am an old man (78 years old) but Latin (Portuguese) and here we associate always the distance to the efficiency...It is wrong of course. By the way I think to make a flipper following your concept...but more easy...I do not know is I will terminate it because I am fighting against a one second cancer just now. But I need dreams till the end...you see.

    Have a nice day.

    Regards from Octávio Oliveira
