    A simple pulley making machine using your router.<br>The final one I make is slightly different, at each end of the threaded bolt I put a cheap chinese bearing.<br><br><a href="http://www.servimg.com/image_preview.php?i=2&u=17515281" class="postlink" target="_blank" rel="nofollow"><img src="http://i41.servimg.com/u/f41/17/51/52/81/pulley11.jpg" border="0" alt=""></a><br><br><br><a href="http://www.servimg.com/image_preview.php?i=4&u=17515281" class="postlink" target="_blank" rel="nofollow"><img src="http://i41.servimg.com/u/f41/17/51/52/81/pulley13.jpg" border="0" alt=""></a><br><br><br><a href="http://www.servimg.com/image_preview.php?i=6&u=17515281" class="postlink" target="_blank" rel="nofollow"><img src="http://i41.servimg.com/u/f41/17/51/52/81/pulley15.jpg" border="0" alt=""></a><br><br>Where I am you can get good woods cheap, like mahogany, teak, etc.<br>But you can not get "finished" lumber, it is very expensive.<br><br>So I make a machine that can make pulley.<br>Probably lots of room for improvement <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><br><br>I found a stainless steel rod and took it to machine shop, and he threaded it for me very cheap. $3.

    You can use it to make "pulley" for bullpup type xbow.<br>Or maybe even "nuts" for the xbow.

    Very Clever !!! I love to see people using traditional tooling in new & unique ways.... nice & clean results.

    A clever idea, in its simplicity. I think it is possible to implement it also in connection with a drill on an horizontal support (using the right bits, of course). It'd require higher rotating speeds, nevertheless it is worth a try. Or, using a grinder and the adequate safeties, it could also be possible to cut simple grooves into metal rods. Extremely interesting.<br>Thanks so much for posting.<br>V

    That is a great idea. Have you seen the wood gears guy. His site has some nifty ways to make stuff accurately and repeatable. Thanks for posting. I might use this for cutting pulley rollers for a belt sander project I'm concocting.

    My router is a cheap plunge type.<br>It has depth regulations.
