I use these links as references when machining:<div><a href="http://www.engineersedge.com/screw_threads_chart.htm">Screw and Nut Threads Size Chart - Engineers Edge</a></div><div><br><a href="http://www.littlemachineshop.com/Reference/tapdrill.php">Tap & Clearance Drill Sizes</a> (that page also has a PDF with metric thread info. And note that it recommends 75% thread for aluminum or plastics, and 50% thread for steels. I have had excellent luck following those guidelines over the last few years. Some places recomment 65% thread for everything, but I don't like that.)</div>

</div><div><a href="http://www.efunda.com/DesignStandards/design_home.cfm">Design Standards</a></div><div><br></div><div>I've been in charge of product design and CNC machine programming at my work for the last 5 years, so I've got a lot of good machining experience. If any of you guys ever have any questions, feel free to e-mail me. I've set up my gmail filters always to mark all regular noisebridge threads as read (to avoid clutter without completely removing them from view) so I normally won't see something directed at me - unless my e-mail address is specifically in the "to" field. So if you want to get my attention, even if you're sending something to the whole group, tack on my e-mail address separately to make sure I see it!</div>
