    would put a little rod over the rollers so the rubber doesnt slip away and you have to put it back every time

    The compound slingshots just look so much more powerful than the regular ones.

    I really love these pulley designs. Seems like you can get so much more power from them somehow.

    Idea for Slingshot channel video topic:<br><br>What about a taking a few shots with ball bearing at safety glasses to determine which type or brand would be the best safety glasses to wear? I realise you won't probably be able to endorse one brand of sefety glasses above another -it would still be cool to shoot the heck out of them for some destruction.<br><br>What would it look like if safety glasses were struck by a ball bearing shot from a slingshot? How many pairs of safety glasses will a 20mm ball bearing pass through?

    <span class="postbody"><br><br>I seem to recall there being a vid like this already, except maybe not different types of safety glasses, but it shows the difference between safety and non safety glasses IR/RC</span>

    <span class="postbody"><br><br>Hi John,<br><br>I have made a compound slingshot called COM BOW SLING since 1975. Have had a lot of pleased customers over the years. I have been playing with slingshots for nearly 70 years. If you were to type in Robert Blair and Slingthing an early unit will come up. Or my name and slingshot or combowslingguy . I have a web site <a href="http://www.combowslingguy.com" class="postlink" target="_blank" rel="nofollow">www.combowslingguy.com</a> As I am an older guy I don't make many any more. I still try to get someone to get involved or to take over. My site says I am not taking orders but, quite a few want them I don't know how to make it fair.<br><br>I am sure that they have more power because more energy is stored. And it is applied more efficiently ( longer power stroke ) . Thank you for the opportunity to put in my $ 0.02 worth. <br><br>It is so very nice that there are places to express our ideas. Thanks Again, Robert Blair</span>
