More gates and railings, but at least welding was involved! The building in the background is my workshop, didn’t have far to travel to site

Yesterday I made a 4" hole in the bathroom wall for a fan.
Should have been uneventful, apart from being over 70cm deep as it's through plasterboard, insulation, block, more insulation, cavity, then two layers of sandstone with a rubble fill.
You can see how deep the wall is, about 74cm
Weapon of choice, trusty Bosch corded drill. Eventually 3 extensions and screwfix's finest Erbaur 107mm core drill.
This model, I can see why it's called GBH2-26. When I did the daughter's ensuite last year, it went through a 90cm wall with a 6" core drill.
Anyway, started ok. Got about 40cm in, then slowed right down. I tried to take a pic down the hole but results didn't show the bit of metal it hit. It was at about 11 O'clock in the hole.
First of all, I thought it may be a wall tie, but this was in the rubble fill. Then I thought it may be an old gutter bracket, they used to use bars knocked between stones to hold the wooden gutters up. It wasn't the end of any lintel, it felt irregular and part of big piece of steel.
As I was angling downwards slightly, I thought the best approach was to push on and hope to get under it. I was somewhat invested by that time and trying to change direction or start a new hole would have been a pain as the target exit point is between a mullion and a stench pipe and just below the guttering.
Eventually, after a lot of effort, swearing, several cups of tea, a dog walk, I got through it. I did try removing it with a long chisel but it was having none of it. So I just kept breaking the core out and pushed on. The core drill still has plenty of life in it surprisingly.
Turns out to be a bit of scrap from when the steel beams were put in the roof of the barn conversion. The guy who did it cut them to size on site with oxy/propane. He must have had to cut a bit off and he shoved it in the cavity before we closed it up. He's retired now, that was 25 years ago but I still see him at the market for a coffe occasionally, I shall have a word.
Got there in the end, I would have liked it a bit higher on the wall but the roof is still sloping down, it came out in the right place which was the main thing.
Lovely view of the IBC taking water from the greenhouse roof.

^ That's a job I have put off for another summer, my bathroom doesn't have an extractor fan so now the shower is on the higher power setting, it's getting a bit steamy and condensation-y. I suspect it will carry on until at least next spring as I've no desire to be opening up holes in the wall now the temperature has dropped. At least mine is an estate house from the late sixties, so I expect it will be a much simpler job. I hope so, anyway, as I don't have extensions or a massive powerful drill.

I feel your pain! Glad my big core drilling for the new garage supply is pretty much over. Still got to do a couple of small ones through the brick pillar where the EV charger is going.
I've core drilled a wall before, hit rebar and switched over to a Starrett hole saw just to get past the steel. You can generally kiss goodbye to the hole saw.

The absolute worst thing to hit is a wire wall tie, the teeth keep getting caught up rather than cutting, especially if the wall is block, it crumbles just enough..

Yet more repair patches for my MX-5 :-/
Nearside front of sill in 16 gauge / 1.5mm, so it needed a bit of whacking to shape.
Tigged a little gusset in to help it:
Swaged in the drains / stiffeners
I've found a copper hammer works well for forming bosses or recesses without adding too much hammer rash.
Just got to paint the insides and weld it up, then it's time for more...

Nice, I assume there isnt much about panel wise for these?

Thanks
There are quite a lot of panels available, and repair sections for the more common rot spots, but not the front of the sills. I was 50/50 on getting a full sill for the outer part (about £100) because the rear needs repairing too, but I’d still need to rebuild all the inner bits (there’ll be about 10 repair pieces on this corner!

Finishing touches to the Walnut sideboard before it gets a coat of finish
All while the poor little hobby CNC spent the day screaming its head off cutting 12mm ply into repetitive shapes to make up 20 wooden storage boxes for my dad who's moving hopefully soon and needs to pack up a very large workshop of stuff he cant be throwing away as he might need it one day

That walnut sideboard is going to look the nuts when it's finished.

are the doors solid and machined to shape?
Yep. started out as 30mm thick oak and machined the face with the CNC. About 20 hours machining time between the 2 doors. My neighbours love me!!!
