The other thing is rather not risk is placing a heavy berkel meat slicer on a large expanse of glass & screw it over again.

These days the large hob is an afterthought in a bygone era of kitchen paraphernalia in terms of frequency of use, imho.

Looking forward to seeing the build.

While I love the new hob and it looked very cool when I walked into kitchen this morning. The highlight of the job was finding the HUGE hole through to the subfloor. That has been whistling away behind the kickboard for years (14+) since my Ex-bil & I fitted the kitchen. What was I thinking! :shock:

How many holes does this house have! Pretty sure that's the last one..... :lol:

I swear that if I added them all up over the years it would be a good sized window space with no window in it, call it a large porthole on a ship, snashed in with the North Sea wind blasting in. No wonder I felt the improvements! :roll:

First find cheap off cut of worktop.
Second finish other renovation "plans" 😂

The portable induction is ok ..for now.
I'd prefer it spent on an ewi course tbh.

Sounds like a great day and enormously satisfying. Tom and Barbara would be proud of you! Today I am howking out the last of the tatties and if time allows processing more apples to the freezer. Heading back out to Turkey soon to get the second eye done so have to clear the decks. On return we can hopefully hook up the LF280 battery stack extension.
Good luck with the trip Joe, have to confess it's not something I would look forward to experiencing.
Still a few rows of tatties to lift here and with the recent rain after a summers drought runner beans are now running amock. Sitting in our garage is a 9.5 kWh LFP batt waiting for cables to arrive in order to add to our system. Along with keeping us as energy independent as current means allow, there's also a certain member of the present goverment I shouldn't like to see prosper from any miniscule supply of gas that might eventually find it's way into the grid due to the lifting of the moratorium fracking. :evil:

Yeah, I know on the fracking. :cry: Rather that than give Putin a sheckle?
Thanks on the 👀, we are heading back out with our son on 23rd Dec too to get his done. Minus 12 so a whole new world awaits. Best of fortune to you on the battery, they are an excellent addition to the tools to stay in RE as much as possible. Are you on Octopus?

When our house was air tested, the biggest air leaks were the keyholes in the doors. Not enough to get it to fail the PassivHaus air leakage standard, but noticeable as they whistled when the air test rig was running. These made the keys left in the locks on the inside get very cold in winter. The fix has been to squirt aerosol motorcycle chain grease deep into the locks. This stuff sets almost solid, like a white wax, when the solvent evaporates. Made them a bit better, but the inside door handles and keys are still always very cold in winter. Shows just how thermal bridging works, though.

very interesting... I wonder if there is a non-(thermally) conducting option, like a square-section steel core - or even a star-shape - with a good insulating layer added on? I don't know if simple solid white PTFE woud be up to the job by itself.
It reminds me of my glass beehive crownboards and wood-framed queen excluders. It took me quite a few years to come to the conclusion that the benefits of each are so great that it's not a problem - you just have to recognise that some of the parts are limited life and hence consumables. And in this case build your house and locks so that you can get in and out and replace the shaft easily when it fails!

The really big problem I have with the locks for our house are the size of them. They are the Eurolock pattern in section, but because the doors are all PassiveHaus ones, they are extremely thick. The length of the lock cylinder is around 145mm, and very few people seem to make them that long, with the right offset where the lever part is. The locks the doors came with are a decent quality, and have the "secured by design" approval marks, but I'm dreading ever needing to replace them, just because they are so long and hard to get hold of.

I would like to try and replace the keys with versions that have a key on the outside and a turnbuckle handle on the inside, just to save having the keyhole on the inside and to make them easier to lock at night, but have had no luck tracking down a good supplier that makes such long barrels. I've been on to the people we bought the doors from and they can't help. seems they have the locks specially made for them in Germany, and their supplier doesn't do a version without a key on the inside.

Needing keys both sides is also a nuisance when we go out, as the outer key will not lock if the inner key is in the hole, so we have to keep moving keys around.

SWMBO was out and about with her Mum yesterday. Ended up in a Red Cross shop where she picked up this small pan for a quid. She carries a magnet in her handbag to test these things. Actually that's not quite true, she carries a fridge magnet shaped like a Hawaian surfboard which is actually a bottle opener in her handbag. None of that single purpose nonsense with my girl. 8-)

Anyway, I used it this morning at 5am (the pan not the surfboard) for my cup of tea. What a great way to start the day. New gear, new way to make tea. Only boiled what i needed and felt like i was on Star Wars, love the boost function. :D

I'll use it again to take her a cuppa at a more decent hour. :)
