So here's the scoop. When Cybele and I climbed North America Wall last fall, I found these bolts on the traverse up and left from Big Sur Ledge. It was very puzzling to me.
What you see below are two bolts side by side - an old one with the star head and aluminum hanger, and a new one. I cannot tell from the photo if the new bolt is stamped with ASCA or not, and I do not remember if this was the case. In other words I have no idea who placed the new bolts and when. I believe the McTopo guide says that ASCA replaced a bunch of bolts on NA Wall, however.
Here is a closeup of the old bolt. Sorry - I should have taken closeups of the new bolts too, but I didn't. What you see is everything I can show you. I recall there being about four to six bolts done this way, and they are in a more or less horizontal traverse right to left.
I am wondering why the old bolts were not pulled, and the new bolts placed in the existing holes?
1. It is hugely easier to pull out an old bolt with "tuning forks" and redrill the existing hole to a bigger diameter, and place the new 3/8" bolt in this drilled-out hole.
2. I have done this 23 times on Bermuda Dunes alone, and a few times on some other routes, too. It's not very hard once you get the hang of it! I have since learned from Dave Turner that you can sometimes funk out these old bolts, instead of using tuning forks. I wish I had known that on the Dunes because I'm quite certain some of those rusty quarter-inchers would have come out more quickly and easily this way. These old bolts with the star head, however, looked rather more robust than the ones on the Dunes.
3. And it's BECAUSE these bolts appear fairly robust, that I wonder why they needed to be replaced - retrobolted at all? Why not just leave the existing old ones? See, on a traverse, the maximum force you can generate on a fall is only 2x body weight, so it's not like you could ever rip a bunch of old bolts out should one of them fail. These decent older bolts probably could have stayed, ya know?
4. I am wondering if whomever added the new bolts thought, "Hey, these old bolts are pretty cool from an historical perspective, so I think I'll leave them in situ and just add the new bolts."
5. I cannot imagine the amount of work required to drill four to six brand new 3/8" holes! My elbows ache just thinking about it!
6. I like Erik Sloan, and for the most part support his efforts. I am not sure I am cool with this situation, however. And again, I have no clue who replaced these bolts. If it was Erik, I hope he will chime in with his story. If not, I'd like his take on them. And I hope whoever placed them will also chime in.
And Erik, if you're reading this, which I hope you will, let's get together this May and I'll pick up a few more bolts and rivets off ya to rebolt whatever El Cap obscurity I will surely end up climbing.
Cheers,
Pete

"Best way to replace bolts/rivits/rivets in a variety of situations?" Keeping it just to bolts, and just to Yosemite granite, this can still be a huge topic, so how about checking out the variety of articles (especially by Chris, Todd Vogel, and Duane Raleigh) here, then asking more specifics:
http://www.safeclimbing.org/education.htm
Those pictures are ridiculous, no reason not to replace the bolt in the original hole, it's easy to drill through the lead sleeve of a 1/4" Star-Dryvin with a 3/8" bit in a hand drill (don't try it with a 3/8" Star-Dryvin though, the bit will get stuck in the lead sleeve - as I found in a 45-minute-replacing-from-stance battle on the first bolt on the traverse on Arches Terrace)..
Mike
The most useful tool I've found for removing bolts is a form-setter's hammer (one-piece metal claw hammer with rubber grip, Estwing brand, etc.). I prefer it in place of a tuning fork because it allows more prying rather than chiseling to remove the bolt, usually less impacting on surrounding rock. A small, thin piece of masonite or similar material with a keeper cord can be used under the hammer fulcrum to protect the rock while prying. For chiseling behind hangers, strike it with a separate hammer.
On larger projects, a tuning fork will become uselessly bent, especially if you wield a 3lb mallet. Even some larger crow bars don't have the pulling power of a long claw hammer.
Cheers.

There are times in our basalt where you aren't going to get the old one out for some reason without too much damage to the surrounding rock. Invariably the bolt will come out part way, however, allowing me to cut it off, push it back in and use colored expoxy sticks to make a very nearly invisible patch.
Theron was kind enough to make me up a couple of tuning forks (from some of Deucey's ebay pins) and I'm looking forward to using them this year...
Greg Barnes
As far as Mike's suggestion, I've found that prying tools such as claw hammers, small crowbars/prybars, etc, increase the chance of the bolt breaking compared to using a tuning fork (starting off with a thin piton to pop the bolt out a bit in either case). I've also found that using 2 tuning forks works better than 1 tuning fork and a funkness. This is for 1/4" only, if you're dealing with 5/16" buttonheads or other large bolts (or the variety of stuff you may find on a wall route), the beefy claw hammer may well be the best choice.

Outside of the ASPCA retrobolt organization, for some reason there is a dearth of info on the web for just doing straight bolt removal. For REPLACING bolts, go to the "Safer Climbing" web site and see the Barnes post below. I'm not dissing them at all. However, if you type in Chopping bolts, or Removing bolts, or How do I get bolts out of my climbing area after some jackass f*ed it up in any search engine: all you get is posts that say something like "oh, you shouldn't chop the bolts cause it will damage the rock". WTF? That's like a kid with a spray paint can telling you to leave the grafitti mess he made alone because if you try to clean it up it will mess up the wall: WTF? You already messed the wall up you dumbass.
I am strictly addressing bolt removal, not replacement. REMOVAL only here.
I do not expect this to be anything other than a rear-guard action which in the end will fail. Those pussy bastards do not understand why bolts can't be used about everywhere, and I don't think some old school F*cks like us will change that attitude, they're coming into the sport as fast as a cockroach infestation in a flour mill. However, I think if some pussies bolts get yanked IMMEDIATELY, then like graffiti "artists" they will go elsewhere. No compromise. Like graffiti artists, you hear the rationals like "Hey, I created that special artwork on the rocks, what right do you have to remove it" or "don't clip it if you don't like it" kind of crap. So if you come over to my house and sh#t in the corner because it makes you feel good, I can't clean it up because I might smear some sh#t around and make a mess? WTF?
Ignore those pissant fools and their ignorant statements and attitudes. We have more right, and a duty, to correct that affront to an intellegent persons sensibility and to do so in a way to minimise damage. Following this method, all that is left is the origonal hole the first jackass with a drill made: and even that is patched to perfection if you do it right.
Without further pre-amble:
Climbing bolt and anchor removal instructions
Generally I don’t cotton much to removing bolts. I’ve had to do it a few times, so here’s some points on instructions for removing bolts. I'm assuming that the party who will be restoring the rock has done the pre-chop discussion.
Do not "Chop bolts" (they don't get chopped with a chissel despite wht Robbins tried on Dawn Wall) and do not follow the ASCA "American Safe Climbing Association" instructions for putting a tuning fork #4 modified Lost Arrow under the thing and working it out unless it's like the star dryvin above or an old manky 1/4 Rawl split shank and yoru intent is replacement. That’s bullshit and ineffecient as hell for straight removal unless you’re Arnold Schweartznegger in his prime. For what they are doing, ie, pulling out and replacing old rusty mank, primarily 30-50 year old Warren Harding 1/4 split shank construction bolt, it will work fine. Won’t work worth a f*ck for removing the brand new 3/8" diameter which was rap-bolted every 5 feet just 4 feet left of jamcrack route when that shows up. And generally leave that crowbar at home unless you are pulling glue ins, way too much work and mess to try and yank a bolt out. Do that if you want to replace one, not for restoration projects.
Here are some real instructions to “chop” or remove a bolt. May I highly suggest that you try this before you go up there. Go to a choss rock and drill and install a bolt with a hanger, just like a real one. Practice.
You may need some or all of this and I might have missed something, look in the pic above to see:
1– big assed Hammer (ball peen style prefered)
metal drift pin or punch for smacking the stud below grade if you have a claw hammer not a ball peen.
1 cordless sawzall "the trad climbers friend" or hacksaw -10-14 TPI blades for your saw.
1 pair of regular style Vise Grips
Cold chisel or lost arrow
Epoxy putty
½ breaker bar or long socket wrench
2 sizes of deep sockets, to fit 3/8 wedge anchors or 5 piece Rawl(Powers brand) bolts which are different sized.
A box end wrench- or open end, which will cover the 2 sizes you might need.
Gloves and safety eyeware are nice
Don’t bring a crowbar unless you are removing Glue-ins, then make sure it’s a stout 3 footer unless you are Arnold.
1 partner with great strength wouldn’t hurt either.
Buy a 1/2 breaker bar or heavy duty socket wrench, not a genaric 3/8 or 1/4". Don't cheap out here, buy quality, and big too. Make sure it's a long one, @ 2' long. Longer is better, socket wrench is better than a breaker bar, as you'll find the first time you match wits with a bolt placed in a corner. The size of socket you need differs for a 3/8 wedge anchor and a 5 piece Rawl bolt. Buy the deep socket version for both sizes. Sure that will cost more but thats what you want up there. Don't come pissing and moaning later to me if you just use a regular socket. Sometimes that works, sometimes the stud gets too high on the wedge anchor for a standard depth socket to work.
Listen closely, this is the important part. PUT THE WRENCH ON THE NUT AND TIGHTEN IT. Within seconds the damn thing will have broken flush, just perfect and you're done, finished and gone in 15 seconds. Rarely will this not do the trick, but there are moments. At this point, take some Epoxy putty, NOT fu*cking regular 2 part runny messy epoxy thats going to run all over f*ck and make a F*ed up mess. You can get the stuff from Home Depot or any hardware store and the link is above. Mix the wood color with some granite dust and it will disappear after you put it on the rock. If you keep it warm it's easier to kneed, as you need to do that to activate the 2 part epoxie process. For Granite, you don’t have a perfect choice or any colors close. Resist the temptation to smear the sh#t all over the place. Fill the hole and only the hole: your goal is that the rainwater won't penetrate and freeze thus weakening the rock (freeze thaw cycle rules up there in the winter) then move on. If you spend more that 1 min on each bolt, it’s because you’re lazy, disorganized and/or a pussy. Unless you are in a cramped position of course.
For Rawl 5 piece, try to just unscrew it, if the winters have caused the threads to seize, and it only takes @ 2years in the mountains for this to happen on a non-stainless 5 piece, the hex head will pop right off. Don't bother fishing out the sleeve which is left in the hole. If your goal is a clean patch to prevent water infiltration, twisting it off so it breaks is better as then you have a solid base for the putty. That's my opinion.
There a few times where that wedge anchor will break slightly high or the wedge anchor didn’t set well originally and it spins. For the high break, simple, tap it down and then epoxy. If it’s a loose spinner wedge anchor, whew, this is where the boys get separated from the men. If the original drillers drilled it deeper than needed, you can do 1 of 2 things. With the nut backed out to within 2 threads, whack it down. If when down it doesn’t bottom out, take the nut off and hope there’s clearance for the coup de grace which will be the final whack of the hammer to make it flush. If not, try cranking it back tight with the wrench, it might lock and then you can just twist the nut off. Or you might consider doing this first which will work in either case, take a pair of vise grips to the stud. Lock it hard. If the damn things say “Made in Taiwan” on it, I’ll kick your ass. There is a difference in “Vice-Grip” brand and it’s the wrong venue for you to learn that lesson, spend the extra money. Anyway, clip the vise grip brand vise grips onto the stud and take an open or box end wrench (which was already put on the nut if it was a box end) and crank it tight. Most likely you won’t twist it off, not enough leverage. So then you back the nut off leaving the flat washer on to help protect the rock, saw the stud flush, Whack-epoxy-pebbles-move on etc etc. Here’s where it gets pissy. A cordless sawzall with the 14 TPI (tooth per inch) will run through that stud in @ 10 seconds. They call that blade “the torch” cause its like torching a bolt with a welding torch it’s fast. Get a cordless sawzall that has a real slick quick change feature that allows you to put a blade in or change it out if it dulls with your fingers in @ 5 seconds. It use to be that you needed a allen wrench to replace blades anymore, not now, get a good quality cordless saw, like a Dewalt with the quick change feature. Stock up on blades too, they will dull quickly. But this is a wilderness area, you say, so you have to use a regular hacksaw. Stanley makes one that tensions very strong. Get quality and save yourself about a thousand saw strokes. Pay attention to the blades you buy as well. 10-14 TPI should work for you. Anyway, if you saw @ ½ way, or less, you can whack it back and forth a couple of times with the hammer and it will metal fatigue right off.
Glue ins are real easy to deal with. Get a long 3’ long crowbar; stick the chisel end into the opening, and twist counter clockwise. The strongest version of these bolts out there, the Petzl Bat’inox, despite the 50KN rating, will fall within 30 seconds of you doing the following. The first 3 twists are the hardest, almost as hard as doing a pushup if you use your knees like a kid. Then it starts to get real easy, real quick to the point where you can do a hand job and spin it right out via hand. Remember that the bolt is still threaded, and it comes out counterclockwise, so bring a watch if you think you might forget that fact cause it’s important. All the other, smaller glues ins will twist right off.
The split shank button head construction bolts and Petzel long-lifes, which look to be invincible as there is no obvious way to get them out, can be dealt with alacrity as well no matter if it’s a 3/8 or a ¼”. Just take your little cordless sawzall, the trad climber’s friend, and saw the head off. If it’s perfectly set, a cold chisel tap right under the head will make a mark for starting the cut. It takes 10-20 seconds to peel the head off with the trad climber’s friend and the hanger will fall right off. Tap and epoxy.
It's real work. Having quality tools will make removal quicker and almost easier than placing them the first time with a fully charged, brand new, I just started climbing in the gym and bought a Bosch Bulldog drill. Now go do your duty and get her done.

JimB, good post. That's pretty much an exact description of what we've employed at Beacon Rock with overtightening to breaking with a large 1/2" breaker bar being one of the primary tactics we use. But we have fragile rock and a pretty much flawless camo color / technique with the expoxy so we have less need to spend an overwhelming amount of time to actually get a problem bolt entirely out of a hole.
For basalt, the best approach to doing an epoxy patch of any size (and I've done this regularly on up to 3" x 3" patches) is to:
Get yourself a fine, short densely bristled brass brush about 2 inches square and tape it around the circumference of the bristles to keep them from splaying out under pressure (you can see ours pre-taping in the lower left hand corner in the gear photo above)
Clean the patch area well of loose debris - but don't over do it
Mix and smear epoxy into the area / shape of the patch paying particular attention to getting it worked into all the crevices; on the edges along the perimeter of the patch use an outward smearing stroke; for all this just use your thumb and press really, really hard
Place the brass brush over the patch and really lean directly in to it hard and repeatedly picking it up and placing it back down between presses; really work the edges especially
Do a final, lighter cosmetic set of presses which will result in the surface of the patch being covered with a carpet of clean bristle holes
Take the butt of your palm and tamp the patch to take the "crispness" out of the bristle holes so that it matches the gas bubble texture of the surrounding rock
This will result in a nearly invisible patch ideally suited to being quickly colonized by a variety micro-flora. It'll be interesting to see how long it takes for them to completely blend it into the surrounding terrain. Some variation on this theme would definitely work for sandstone and I suspect some surface texture implement could be found that would work well for granite - maybe one of those finely coiled SS commercial pot scrubbers...

But deleting other's posts and reposting a summary, then expecting a continuation of thought;i it's kinda draconian.

If we get a plethora of information here, i will be happy to organize it in some sort of document and post it. Any and everything is appreciated.

From: Mountain View, CA One thing that I didn't see in this discussion is that there is an easy way to remove the lead sleeve left behind in the hole from a Star Dryvin.
You can use a lag bolt of the same diameter as the hole and about 1" longer than the hole depth. Thread the lag bolt into the hole using a wrench until the bolt bottoms out in the end of the hole. Next, use a crowbar, funkness device, tuning fork to remove the lag bolt from the hole.
If all goes well, the threads of the lag bolt will have cut themselves into the lead and when you remove the bolt, the lead sleeve will come out, intact, with it.
Thanks to Clint Cummins for this tip. It really works!
