good point... maintenance of personal belongings is not my strong suit. thanks. getting the sand out would probably be a good start..! funny though, my old Bosch bulldog never needed jack for maintenance and is still running strong after almost 10 years.... whole thing just feels way sturdier and more beefy than the modern new "Joey K model" plastic-y drill.

ha ha ha, the Joey K.

I found muddling has worked just fine for me. Never know unless you find out for yourself. I just thought I'd ask around, and maybe get an opinion from someone who has actually used one of these, or something similar. To clarify, I am looking to bolt with it. Judging by the softness of the corbin sandstone, which is comparable to cement, I would assume the rotary drill would work just fine. A hammering drill would be best suited for harder rock such as granite. For those of you who think bolting is rocket science, all I can say is that a little bit of reasoning, logic, and ingenuity will keep your buns off the deck.

Haha classic! And you feel a need to reinvent the wheel because...?

I don't want to drop $400 on a new drill when I already have this one....

So why not just try it out then? You're the one with the freaky wood drill, not us. I am pretty sure by "core drill" for concrete, Stihl means once you already have an initial hole. I suspect it will not work or you might get one painstaking hole if you're lucky. Unless you're bolting total choss, the rock can be harder than you think. Also it doesn't look like an SDS mechanism, so good luck finding a good masonry bit to fit that thing. And for god's sake don't use some 3/8" crap or the cheapo wedge bolts you found at the hardware store.

BTW, putting bolts in rocks on rappel is not some glamorous fun pasttime. It's a tedious expensive waste of time for grumpy old men... don't know why it's suddenly so trendy. Climbing is the fun part. Ground-up trad climbing... now there's a little more artistry to that.

why reinvent the wheel? i've tried to get some guidance and even offered compensation..as to why? show appreciation/return the favor/know what it is you are grateful for...

Go rebolt some routes with me Blake or Patrick, you'll learn (more or less) everything you need to know.

+1 - except for the part about grumpy old men. It's still a tedious expensive waste of time for a happy young(ish) woman It's also rather painful and tiring. It's VERY good to practice with those who have lots of experience. I learn new stuff with each person I beg to take me bolting.

So today I decided my Xmas present to myself is going to be my very own drill. I'm hoping between now and Xmas I might find a used one. If you've got one you're looking to sell, PM me.
