Hot Dipped vs Zinc Coated Galvanised Nails - which for roofing?
markc replied to Oxbow16's topic in Roofing, Tiling & Slating
Hot dipped zinc coating is better for weather protection but they can be sharp, a bit rough looking. BZP is bright zinc plated and done by electrolysis so the coating is thinner and more even (and usually shiny) but not as hard wearing. -
Looks like it overheated and melted the brazed joint. Spear point drills need to be kept cool either with water or compressed air (water is far better) and run slowly.

I would say that’s a drain yes

rounded stones to delineate garden space on driveway
markc replied to johnhenstock83's topic in Driveways
Hi, some people cut them, others leave then whole and have tapered gaps. What they sit on depends wether you will be running over them or not. But as you mention flower beds then a bit of concrete underneath and haunches at the back to prevent spreading .. again all very easy to see on YouTube -
Agree with @Mr Punter , wrong colour and look for asbestos. Good respirator and Google’s anyway and disposable coveralls to minimise inhaled and itch

markc replied to johnhenstock83's topic in Driveways
The ones with rounded edges are tumbled and a quick look on YouTube for laying pavers will show you how to do it, much easier than trying to explain -
Core bits, especially lager diameter ones really need a water supply to flush away the debris otherwise it collects at the face and puts a lot of strain on the motor, pulling out to clear the cutting dross every few mm helps if doing it dry. I have done lots of diamond drilling but dont recognise the mount on your new drill/motor, looks like it is missing a chuck

The light up tester is working correctly near the plastic panel because there are live components behind there. Is the shock from the metal parts or from the door? If it’s the door then mostly likely a static build up as opposed to an electrical problem. If it is the metal parts then possibly an electrical issue and possibly due to a loose or broken earth due to vibration, replace or even add another earth “bond” connecting the offending panel to the other earthed areas/conductor.

Unfortunately small genies are a nightmare to spec. We have a lot of machines with 2.2kw single phase motors that will start and run happily on a 13amp plug. We have a old heavy Haverhill 5kva generator that has no problem at all running these machines but a new 10kva won’t because the voltage drop on start up causes our machine to shut down.

If the tree is suffering from ash die back i believe it has to be left on site or burned on site or can be transported but only by authorised transport and disposal contractors.

Good morning and welcome, loads of info available with a search of previous threads, failing that ask away.

Looking good the retaining walls will be rendered so exterior paint as soon as they look dry, couple of damp patches visible on the longer wall. Sand/cement doesn’t breath anyway so paint spec directions should be followed as some paints should only be applied in minimum temps and above dew point etc. whereas others are tolerant of cold temps and damp conditions. interior really needs to be left until windows are in and you can see the plaster is a uniform colour

In a king post truss the post is in compression, keeping the tie (bottom cord) and ridge from coming together. This is why it is very important to assess a king (or queen) post truss before loading the tie as the post could well be in loose tenons top and bottom. Sometimes the tenons are pegged but that was just to prevent it coming apart while being lifted

@Jimbo37 we really need more detail of what it is you are or have built in order to give an informed answer. Masonry? … brick? Block? Concrete block? Stone? you say plastering but then ask about inside too … you are having external plastered walls? Sheltered? Or is it render and not actually plaster? a few pics would help

Removing more from the bottom is going to give you a top heavy stack rotating around the ridge line. Stick to a lintel at loft floor level if you are keeping the stack

markc replied to DanBog's topic in General Self Build & DIY Discussion
Haven’t looked at the tutorial but if you need this type of bearing to stay solid/aligned then you use two back to back so the rod prevents “self aligning” -
As you have it and secure with concrete unless you need to keep it accessible but I can’t think of any reason why.

HV conductors in the road and all the necessary switchgear and cabling in ducts too. If only a short length is energised at a time so the car covers it, that’s a lot of switchgear to be constantly maintained. Then the car can only be directly over the conductor so swerving to miss other cars, dogs, cyclists etc. isn’t going to go too well.

Too many people on the planet full stop.

Don’t even think about coatings if you want it to look like wood. Sand blast is messy but works well, ice blasting is pretty mess free as only the removed paint/varnish is left but it’s going to take a lot longer. If the timber is pretty flat and hole free then the spinning (in a drill or grinder) needle gun wheels (stiff wires that hinge on pins around a disk) work well but are evil things better left to specialists.

Can you get a pic showing the roof?
