Again, J bolts hooked under reinforcing mesh or some similar design of holding down unit with plates and long studs. Windage against a gate and offset loads will just worry chemical anchors out over time. With something locked into the concrete you're trying to "worry" the whole, large concrete footing.

I'd cast in J bolts for that as a "holding down unit". Hooked round mesh going down into the concrete. Don't get me wrong I love chemical anchors.

Try this before cerium oxide: https://www.ungerglobal.com/uk/products/rub-out

Jewellers rouge aka cerium oxide works a treat to bring up scaled glass. We used to use it to get cement stains off glass. It comes in different grit sizes. We once used coarse to fine getting burn marks out of glass that some lad had caused with angle grinder sparks.

Plus you can look back to that point where you had perfectly flat, boarded walls and think "If I'd have "turned right" and accepted a mate's proffered help on the tiling..." Guess who turned left and had a go himself? 😡

Can I just clean out and fill these mortar gaps?

Well it could do with being a tad tighter but it won't come off in a strong blow:

Getting there. Hopefully fitting it in a bit:

& you've been caught!

More gone east than West then?

Big in Japan apparently.

Yes. Fit stainless screws and black screw caps. https://www.screwfix.com/p/timco-4-9ga-100-pack-black-plastic-screw-caps/378kf

Is that für ze tanks?

Fantastic! Can we see some more pics.....maybe close ups of the locks and security measures? 😉

You have absolutely no idea how close to the truth you are. Buildings either side of that street have seen a fair bit of Police activity over the years. For what you're getting at is a couple of streets over.

Butt welded:

Hasn't A4 80 roughly the same tensile strength as Gr8.8 mild steel?

I spy a huge box of tissues on the right... 😉

That's a good shout actually. I've a cable tray setter I made when at college, that might do it.

Thinking to fire up the plasma in the morning and cut a say 16" circle out of some thin stainless sheet I have here as a start. Maybe drag the torch round an old wheel rim. Thinking won't a flat plate be noisy in the rain? Is a conical cowl necessary? I've no method either of rolling a downturn/lip on said disc.

All I got from that was "hands free".

I know using stainless electrodes for electrolysis isn't a good idea as it produces toxic hexavalent chromium, Cr6+ at the anode. It does work mind as I've tried it.

Grade A2 nuts and bolts, by the sea, end up like a Swiss cheese. A4 is what you want.

Non working chimneys. Also considering making something like this:
