    Is it worth using rollers in a slingshot crossbow design? Do you get more power, or does it only add complexity?<br><br><img src="http://i49.tinypic.com/243fg4p.png" border="0" alt=""><br><br>I was wondering if number 1 or 2 is the better choice for this. Number 2 if stretched correctly will stop the rubber band at the end which would (in my eyes) be a advantage to ease if loading and consistency, but will the rubber band hit itself? Or should I drop this idea and use a standard slingshot type setup? I am mainly interested in this design so that I dont have to mess around with standard methods of attachment(I am not good with tying knots).<br><br><br>And lastly what draw length would you recommend( how long rubber bands would I need for that? and where can I buy Terabands for not too much money?)? i thought about using marbles and 15 mm steel ball bearings.<br><br><br><br><br>PS: I apologize if I ask too much and/or come off as unknowledgable on this subject.

    Rollers are definately worth a try, but don't prestrech your rubber more that 1.5 times. Thera band can bought on ebay and at orthopedic and sports stores
     

  3. <div>ROLLERS!<br>The trigger is a really good idea but will this be able to shoot 15mm marbles? when I first looked at it I thought that it was for a sling x bow.<br>anyway good design and good luck making it.</div><div class="clear"></div><div class="signature_div">

  5. <div>yep that is the type of rollers that i am thinking about but if you are going to want to make it out of thera band (or flatlands) then you will need tall rollers (like of joerg's bullpup crossbow ) instead of the small ones that he uses in his vid</div><div class="clear"></div><div class="signature_div">

    Read <a href="http://theslingshotforum.forumotion.com/t1965-drilling-holes?highlight=drilling+a+hole+++roller" class="postlink">THIS</a> topic...onnod had a great idea using them as rollers and it should work great with bands. The plastic ones will be the best choice imo.
