I can't imagine the hell of screwing 12" or 14" lag bolts into the playa by hand. And I'm bringing spare socket adapters and sockets.
Felt like you were trying to screw them into a 2x4 didn't it?

That's why I can't see them pulling loose even under extreme conditions. 8)

Do cordless (battery) impact drivers stand a chance of getting these screws into the playa, or is corded drivers a must?

As always, there is more than one way to skin a dead rabbit.

However, in my opinion, my corded 1/2" electric drill seems to set my 1/2" x 18" lag screws quicker and with less effort than my battery powered impact driver.

Quite frankly if FossaFerox and Figjam are confident in them, I am too, and they seem nice and strong. They're at least as good as that 3/8" rebar people use. I also attached some chains to them for easier tying. The hex head on them prevents the chain from coming off, and if I were really afraid I'd put a washer on them. I got a box of chain at the department store (Fred Meyers in this case), and a bolt cutter in their tool section. You can find that kind of thing at other hardware stores.

My socket set didn't have a connector that was compatible with my impact driver; I had to buy one outright. You don't want to be caught out there without that one small part that you need. The lag bolts have 9/16" heads on them; you need a 9/16" socket to drill them in. I'm almost considering getting another 9/16th" socket just in case this one gets lost to the sands. Otherwise, I'll be stuck with a wrench or need to use a 15mm socket, which isn't quite right. That size is also handy for bikes -- especially a deep one.

The impact drivers use a 1/4" shank with an indented area that the driver grabs onto. They look like this (the small side). In that case, the shank is connected to a 1/2" socket adapter, which then connects to my 9/16" socket I got in one of those many-in-one kits. You could probably get something like this that will attach to the 1/2" (somebody correct me if I'm wrong). I got one of these sets just in case, but I should've really studied the details because you need 9/16" and the largest in that set is 7/16" (so don't buy that set!). In addition to the Dewalt adapter, I got this 3-piece set, just so I could use some of the other sockets with the drill. It's an inexpensive Chinese brand and it's just in case.

Worse come to worst, go to your local hardware shop and ask them what will work. Milwaukee is a good brand, Dewalt too. They're all metal anyway, so even a cheapy would probably be okay. Just make sure you have them.
Awesome, thanks BBadger. So I'm thinking a setup like this:
  • Corded Impact wrench (has a 1/2" male socket):
  • 9/16" impact socket head with 1/2" female socket:
  • 3/4"x14" lag bolts:
I wouldn't need an adapter like this for that setup,right?

I don't see anywhere on the lag bolt websites saying that their heads are 9/16". Maybe that's just an impact standard?

An impact driver won't need an adapter. That's for using a regular drill.

The head size will depend on the Bolt size

3/8" bolt will have 9/16" head.

1/2" bolt will have 3/4" head.

5/8" - 15/16"

Does anyone have a contingency plan for if and when these bolts may shear due to unknown factors such as, wind force, load angle, ground density, buried objects (wood, rock), metal fatigue, or new operators gone wild with high powered impact guns that they have very little experience with? If it's as hard as driving into wood, then there is the possibility of any of the above occurring.

Don't forget your post-hole diggers and vice-grip pliers...You wouldn't want to leave those for the next guy, would you?? What, you're tired and you just want to go home? Not so fast...

Practice responsible lag screwing.

What if you have like 500 lag bolts sunk? Will it be easy then?

Or will they kick dirt over them and make that reservation in Reno?

If you break more than 2, you're doing it wrong!!!

They will only break going in, if at all, and I haven't hit anything on the playa hard enough to break one yet. :lol:

All of this discussion is making me feel a lot better! Figjam's advice has always been spot on!

I invested in 50 - 3/8" x 14" lag bolts and lengths of chain to get away from the rebar this year. I HATE REBAR! (Says the person with the scars to prove it!)

I admit, I was having second thoughts...

We always had to pound in 18" 5/8th" rebar, and so I'm thinking that this won't be terrible by comparison. If worse comes to worst I'll have a regular ratchet wrench. I"m certainly not using 500 of these things.

I exaggerated a bit to get eplaya's attention, but you know what I'm talking about.

20 or so bolts, screwed 14+" into the ground, with the heads missing. I'll bet money that nobody's expecting them to break, but if they do, who will be ready? Who will kick dirt over them, while trying to book a luxury suite and dinner reservations at the Peppermill, or jam back to Reno because they heard the pool party @ The Sands is Off The Hook, or their fav DJ is staying @ the GSR and they need to go blow them or give them a wristy.

I doubt the old vice grip twist n pull is going to work with these, they will have to come out the same way they went in, one turn at a time.

Probably the same people who prefer to pound their rebar in the last half inch rather than pull it out.

This isn't a lag bolt specific problem. If the bolt head sheers you can't use the bolt as an anchor anyway so assuming you need it to be in that particular position you have no choice but to pull it out before driving the new one.

Also, I can't imagine anything less appealing than an after burn party at the sands. There isn't enough chlorine in the world...

I'm going to try some of these out this year, see how the fit my application.

If for whatever reason they shear, or the head rounds, or they get bent so that they are difficult to retrieve. I will have a whole set of corrective actions lying in wait for such circumstances, they'll wish they had just agreed with me and come out on their own when I'm done with 'em...

The highway, a ton of soap, and my own bed are more my scene, but I don't leave until my campsite (and last year, my neighbor's) is/are pristine.

Do you know how hard it was to find a ranger at 4 AM on Monday last year to help deal with the sizzling, leaking deep cycle battery our neighbors abandoned? With no street signs, major landmarks, our even knowing where they were camped? Delayed our exodus a good 15 minutes to help deal with someone else's mess.

Did the ranger help you load the battery into your car? Those cores are worth $10-15 each all day long...

No, I don't know how long it takes to find someone else to take care of my problems for me. Load it up and be done with it or don't bother with it, rangers aren't really there to pick up batteries that your neighbor left behind. There's a BIG TRUCK and crew that are charged with that sort of thing, the same poor souls that had to retrieve all of the 55 gallon drums that the knuckleheads left behind in my hood.

Ok Jackass, this is straight from experience.

My first year I used 1/2"x18" rebar with a 1" piece of angle steel welded on top for a hook and to drive it into the playa.

Being lazy, I looked for something easier to work with.

As I was building the playapod, I was using lags through the steel frame to hold the 2x4 wood frame to the base.

The holes I was drilling were about the size of a grommet, and that's where the idea came from.

So the second year I found my 3/8"x18" lags and used them.

The drill I took with me is the one in the picture, and when installing the bolts on the playa, getting the last 4"s in the ground would really bog down the drill.

Image

That drill is not quite as strong as a hole hog but damn close.

Never snapped a lag and I'll be using the same bolts this year.

It will be their 4th year to the playa, and I've used them at all the regionals.

IF you CAN be reassured, I hope that does it!!! :lol:

Dear Mr. Jam,

I have no doubts that a man of your experience can do this all day long w/o breaking a bolt. I'm more concerned about the 1000+ new operators that have invested in the FIGJAM LAG-BOLT EXPERIENCE, who may have no experience of when to let off that trigger. Some of these impacts have so much juice, that if the bolt binds, bolt heads MAY shear. As a trained and competent tool operator myself, I can tell you that when they're new and you don't yet know their limits, you MAY roach a bunch of hardware before you figure out the tricks to it... I've broken a TON of stuff myself, that's why I have this killer "insider knowledge".

...It was leaking acid onto the playa, the ground was bubbling, and the battery itself was making an audible hissing/sizzling sound. We were sleep deprived, physically and mentally exhausted, and lacked the safety gear necessary to deal with our neighbor's "donation" so no, we weren't prepared to haul it ourselves. We only found it because we did a sweep through our neighbor's campsite once we realized they failed to take down their perimeter tape/stakes. We alerted a ranger assuming they could in turn alert someone with the power to limit the damage it was doing. It still showed up as a small red spot on the MOOP map because they probably had to dig the soil out once the battery was transported. Don't you dare try to guilt me for going above and beyond but being unable to magically resolve a fucked up situation.

Fossa did the right thing. No fucking way I would have touched it either. Get DPW in there with a utility tractor with a front bucket, scoop it up, and use the bucket as a blast shield while transporting it to a steel trashcan. Drown it in water, cover it in bicarb, and dump the whole shebang into a box of cat litter for proper disposal. Done, and safely so. Batteries liberate hydrogen gas. Hindenburg. Fukishima. You do the math.

Only a real jackass would futz with something like that. Oh... Wait. :mrgreen:

Pops has a "hammer drill" I can borrow, but the recommendation here appears to be an impact wrench. Just wanted to confirm the latter is optimal before I pull the trigger (pun slightly intended).

For anyone wondering, an 800 W Whistler inverter CAN run the Porter Cable impact driver. If you play with the trigger and start/stop rapidly you can freak it out and have to reset it, but if you just click, hold, release, continue it works great. We drove an 18" by 1/2" bolt into the ground in my camp mate's front yard just now, when we pulled it out we realized we'd hit a tree root partway down and didn't even notice. If it weren't for the sap we wouldn't have known.

I understand the difference, but I'm still curious if a hammer drill will work as well as an impact drill, with the latter being the one that people here seem to recommend.

A hammer drill hammers down on the screw, while an impact driver spins the screw. By definition, the impact driver will do a better job, but that's not to say a hammer drill won't work. I dont know if you risk damaging the bolt or the socket, but i expect that's a possibility. I'd say find some REALLY hard ground, and put a screw in/out 5 or 10 times and see how everything holds. I'd bring some backup sockets just in case. Our camp has 1 impact driver, but I just bought a second one and will keep it boxed in the truck so I can use if needed, or return if not. Impact drivers kick ass.

Hammer drill doesn't hammer down on anything, what it does do is drill with an "impact" feature when the going gets tough. They are called "hammer" due to said impact feature.

Both will work fine, that hammer drill will probably be stronger than the impact. Due to the fact that the hammer drill probably accepts up to 1/2" tooling, whereas the impact only accepts 1/4" hex shanked, quik-connect tooling. The drill chuck can grip anything round or hex up to 1/2" OD, impact- much more limited but still very handy.

Now if the impact was a 3/8 or 1/2" square drive, then that's an entirely different animal altogether...
