I ended up getting a 12" 3/8" flathead at Home Depot and it works very well. Thanks for the suggestions everyone.
I don't want to come across as if I'm picking on you but, I'm a little skeptical about someone who says they don't need a lecture on the safety of setting his/her own bindings when posting threads like this, as well as threads like that ----> http://www.epicski.com/t/127393/328mm-boots-in-327mm-bindings
Don't get me wrong, we've all been in your shoes and had to learn some time, but these are questions that reveal something about your binding knowledge.
I've read DIN charts, I've researched DIN a lot, and I need my DINs higher than some ski shops are willing to set them. I huck cliffs and that kinda stuff, with a type 3 they pop off way too easily. When I demod skis and they set them at my type 3, one popped off my first run. And it's not an issue of forward pressure or anything else, it's not just one pair of skis. I know what DIN setting is right for me, I just wasn't sure what screwdriver head size to get, and regarding the other thread, I'm not a ski tech, no one has ever told me how close the bindings need to be set to the bsl. There's really no way I would have known the answer without asking. Thank you for your concern, but I know what I'm doing (besides the things I asked about, of course).
Mostly because my dad will be coming to Utah to ski with me once or twice a year, and I will be letting him use my skis some of the time (we have the same boot size). He skis with a lower DIN than I do. Also because shops aren't always willing to put them as high as I want, and because not all bindings are perfectly calibrated so any time I get a new pair of skis I'll test it out a little bit lower than I want and then raise it as needed.
I'm trying to give him the benefit of being new to the sport or......something.
I mean, there are a few of his/her threads that can be perceived as such. Like this one for instance. Are there any triple black diamonds in the west?
I'm not new to skiing, just new to working on skis. As for the triple black diamond thread, as I said in that thread it was just out of curiosity. I know trail ratings are very subjective. I've skied Corbet's and other similarly difficult marked runs, I've skied triple blacks, I've skied unmarked terrain more difficult than any of that. It's not like 'I want to ski triple black diamonds because they're the hardest trails' or whatever, I know that's not true. It's just something I've been curious about for a long time.
Welllll, with the username, I'm not sure of gender, but the other thread I posted about is a pretty big BSL so I'm going to assume that its a "him"
That BSL also implies that ... he either a) has a very large foot, or b) is in a boot that is too big, which is common among folks who are young in the sport, looking to improve their knowledge.
This is why I'm giving him the benefit of the doubt and not assuming that he(or she) is trolling.
I am male, and I have the correct boot size. I got my boots at Deep Powder House at Alta. I had my feet measure by a bootfitter and got the recommended size. I do have big feet.
Well, all that makes sense to me, even your means for 'calibrating' bindings for your needs. I'm not a responsible enough person to adjust my own bindings, but others are braver, bolder, and/or more careful than I. Carry on!
