Bike Storage: Wall mounts, stands, lock-ups, sheds, etc.

Hello there,

The toast racks. If you bolt them to concrete, how difficult is to get them up again two years later?

What's the bolt going in to/hopefully coming out of? If it's an expanding sleeve in a drilled hole in the concrete, then it can probably be done up and then later taken out with an impact driver or impact wrench, or even just a massive socket set with a scaff pole extension, but if it's somehow being set in to wet concrete that would probably be a more permanent thing, with lots more destruction required to remove it.

Yes it'll just be in an expanding sleeve thing, into long dried concrete. Thanks for the help!

Was finding it difficult to locate any YouTube videos on it.

Bleurgh... Was there last night dropping off some stuff. It's not concrete out the back, it's square paving slabs. I'm assuming if I stick an SDS drill into one of those it'll shatter it immediately.

Any other options to secure it to a paving slab??

Hit a paving slab hard enough once it’s partially lifted and it’ll break- I would not use one for a ground anchor.

You can drill slabs with a core bit on non hammer mode, but I wouldn’t bother as THEY could just break the slab to “borrow” the rack.
You could remove a slab dig down and replace it with a concrete pad and then bolt to that? If you push some rebar into the ground around the hole and down to spread the load you won’t need to dig down too deep.

You could always use a couple of these

As long as you can’t turn them, hence using 2 together, they are near impossible to remove without cutting them off.

Maybe I'm being a bit thick, or still not fully awake, but can't visualise how these would be used in conjunction with the toast rack

If you put rebar into the ground, wouldn't it be an entry point for rust? Or did you mean put rebar into the hole, but have it fully encased by the concrete?

That

A bit of lateral thinking involved, but I used them at work, on grass for a temporary stand while works were being done on our permanent stands.
We put the ends of the stand through the loop and put a hefty padlock though a hole in the end. We used 2 screws on the diagonal corners and it worked just fine for a couple of months. No body wants to steal the stand, so it’s just got to be a pain to steal not impossible.

I can visualise this alright. Sounds workable.

How easy / difficult is it to get one of the hurricane anchors into the ground? Is it just brute force with a big metal rod through the metal loop acting as a lever, or do you need a particular tool?

We used a length of scaffold tube and hossed it in there. The first one was easy, but there was still no way that was pulling out. The second one was pretty hard, but once it got going it wasn’t too bad. They make 500mm ones as well, which would probably be ample in solid ground.

Any recommendations for a cover for a bike to to be left outside? Only one bike but a chunky sit up and beg jobba, preferably something that you can lock through as well.

Also, any suggestion for the best way to secure it? There's a brick wall next to it so I'm thinking just some kind of hoop in there to put a lock through. It's only worth a couple of hundred quid and it's under a security camera so not looking for anything too extreme.

I asked this recently in the cargo bike thread, some good replies there

How long should it take to drill a 10cm deep hole in concrete, with a 16mm SDS Plus drill bit? The drill has 850 watts of power, plugged into usual 220v three pin socket. Doesn't feel like it's making much progress

Can you start the hole off with a smaller drill bit?

Sounds like the drill bit is fucked. Does the head look OK? Sometimes the little brazed in bits can get damaged.
As Joeboat says, I would start with an 8mm so the big drill has a bit of an easier time.

Is it reinforced? Could have hit a bit of rebar and not have the bit for it...

Don't want to teach you to suck eggs, apologies if this is super obvious, but I have seen people drilling away at something for absolutely ages with the drill in reverse gear...

Edit: although whether it makes a huge difference when smashing in to concrete with an SDS I don't know...

It shouldn't take too much time and you should see some progress already, make sure it's in hammer mode and your bits are good and sharp, maybe an idea to start with a 10mm bit instead

I have started with a 10mm bit already, got in about 1cm deep as a pilot, as per the instructions on the bracket. The bits are brand new so there's no issue there. The drill was on hammer mode. No rebar in the concrete.

The drill is pretty old. I suspect this is where the problem might be. I've asked a neighbour for a loan of theirs.

Still, can anyone give a rough estimate of how long it should take?

It's pretty difficult to say. The important figure with an SDS is the impact energy, not necessarily the power. Concrete also gets harder with time so an old slab will take much longer to get through. I would expect with the right setup not more than a few minutes. I would drill full depth with the pilot if you only have a 2-3J impact energy.

I was doing the same kind of thing but into granite, I had bought a second hand SDS drill to do so, although turns out the hammer function was not working properly so didn't get anywhere, borrowed a mates and it flew in, had to drill 4 x 16mm holes and 4 x 10mm holes, impact energy is where it's at as @chiroshi is saying

Wow! That’s a massive trike!!!

Looks again :D
