I drilled a bolt hole at Pinns yesterday, less wailing and more consistent tapping seemed to work better. I choked up on the hammer quite a bit too which helped. I tried out the consistent turning method with about 120 degree turns before grip changes and I liked this too. Will keep trying this out and see the difference over more bolts, but overall seemed better.

Me too but it was nothing new for me.

All of you missed two of the most critical "techniques."

1. Periodically miss with the hammer and scar the knuckles on your other hand;

2. Swear a lot.

I drilled 3 bolts yesterday and was reminded that every hole is different (insert joke here?).
My technique varies somewhat on a case by case basis. I did notice that I tend to tap 6 or 7 times per 90 degrees of rotation. The last tap is more from inertia. My wrist doesn't go 120 degrees - so I am tapping 24 to 28 times for a full rotation and if the hole is going well, it takes very little force to turn the drill. if the rock gets chunky I let the drill bounce a bit in the hole (loose grip) and try to never force the turning. Forcing the turning will mess up your wrist and can also break the spring in the Rocpec. I think I have broken 4 springs over the course of hundreds of bolts. Petzl sent me replacement holders for all of them.

Huh, I hadn't heard about Petzl sending you replacement holders... I'll have to see if I can find my Rocpec holder with the busted spring and send it off to them.

 Brad should start a thread about swearing technique

 He is both a master swearer and able refrainer when he chooses.

I'm an amateur compared to Katie. She knows all the cool words.

One of the latest trends? Calling someone who's an a##hole a "douche canoe."

No offense to any GOPs around here but I think TRUMP is the newest swear word.

 Our rent-a-potty door on the job site was inscribed with a sharpie as Trump Tower sometime earlier this week. Someone was obviously oozing inspiration.
