fordman, understanding you were asking jerrykr about springs...not that scientific. Just something short enough to fit on the bolt you're using and strong enough to hold the vent caps. I found mine at local hardware store no problem. HD will have them. Only done one cook so far but like the dampers...I know No Pron! Wasn't worth posting.
Ribs this weekend and will post pron. More practice with temps.
Greenlee makes some step drill bits comparble to the Irwin Unibit. About the same price range, but another option especially if you plan to drill larger than 7/8". In the Electrical aisle near the conduits at HD and bLowes.
