I wasn't really planning on coming to MVOR this spring, due to work scheduling. It may change, in which case I'd be happy to show you some bolting standard skill sets.
I started setting bolts at VPI in the late 70's, using 1/4" Star drills and split-shank bolts. My, how times have changed! Mostly now I use a Bosch Annihilator SDS cordless hammer drill with 3/8" stainless bolts. (Howie just built me a custom pack/cover for this drill, keep an eye out on the Nylon Highway page). For bolt climbs I overdrill the holes; this extra depth allows me to drive the bolt (minus nut/hanger) flush with the cave rock and conceal it with a dab of mud. For permanent anchors I like the 3/8inch Ramset/Redhead studs, similar to the power wedges shown above. My last box of stainless set me back around $50 from my source.
I also have some of the 8mm studs from Raumer, and have used the Stick-up climbing pole system (see the
http://www.cavediggers.com website for more infol). I've got a lot of time setting the "classic" Petzl 8mm self drives. Last time I went caving in Canada I was able to replace the rescue cache bolt kit with a Petzl 12mm self-drive setup, with SS hangers and bolts to accompany the 12mm shields/cones. I've got some other unusual bolting stuff I've accumulated over the years, including a NIW Troll bolting kit from the '80s.
If you PM me with your specific requirements I could probably set you up with everything that you need for your project.
In the interim, go to the Cave Diggers website (Mark Passerby runs it) and read and re-read the chapters in Alan Warild's updated "Vertical" book, available free for viewing on the website.
