You’re not mixing up HSS and TC blades are you? Though I’d be surprised if you could get TC for just double the price Either way, I’d put my money into more regular sharpening over more expensive HSS. Whenever I start to get problems with my planer, changing to new sharp blades seems to make...

HSS isn’t really a fancy thing it’s a commodity, so long and they’re sharpened well any make will do from what I’ve seen. If they are old, check for any cracks as that could spoil your day. Having a spare set is useful and costs about £25

But how exciting would the programme be if they cut down a tree and then filmed it drying for a year whilst they waited to see what character boards survived to influence the design. There’s always going to be people who don’t understand things, sadly some actually aren’t even capable of...

Nailed the first part, but still used a thermodynamic equation, it’s almost like sometimes details are needed and sometimes they aren’t.

Why are rocket nozzles the shape they are? Explain please

It’s so typical of TV programmes now, I watched one on rockets and they didn’t even use a single thermodynamic equation to explain the design… …or maybe the programme was not orientated to that sort of viewer.

Longer screwdrivers often have larger handles, so you can apply more torque, that’s all there is to it. As gcusick says, you can’t lose torque down a shaft (unless you mean in a transient like on a quill-shaft)

Yes, that was my point, half of a 2.4m sheet puts the CoM after the load limit window despite the sheet fitting easily enough. I think if you put one of those fifth wheel load points in it’s all lovely, but in general most pickups seem to have the illusion of being able to transport a lot but...

With a new Ranger you’d also be placing the centre of mass of the load outside the recommended window (it’s surprising tight). If you go looking for crash safety on Fords you can find a forum where people discuss where to add steel to remove the crumple zones so their truck isn’t so damaged in...

You can get ball-nose cutters that long, but this really sounds like one of those times a different approach is needed, for a start, can you really see much of the bottom of a 50mm deep 25mm wide pocket? If no, is a flat bottom a problem?

That’s a huge cut to do on a router with a single cutter pass, but you can cut incrementally. Use a straight cutter to take out most of the material then a box core cutter to finish off and put the root radius on. If you want a single radius to the bottom then you will need a cutter 25mm wide...

There’s very clear rules on overhanging loads, note the disparity between front/back and side, because on the side is how you catch a pedestrian. Someone at school got hit in the head by a 150mm length of plastic soil pipe that came off a van, she had three operations to mostly put her face...

This guy again…. next up, do carrots really make you see in the dark? That other thing we all know but really, they don’t. At least he’s stopped measuring force in kg

Use an interface pad with abranet if you want your lovely sharp edges rounded over, if not dont

The blade needs sharpening when it’s no longer cutting well. The blade needs changing when there’s not enough carbide left to sharpen. I use abranet, I’ve not enough life left to spend any longer sanding than required, but it’s not cheap.

It sounds like your primary filter is compromised,

Some places will sell you material cut to size cheaper than the per meter price, cut way better than you can yourself. It baffles me and pleases me simultaneously.

Price can vary a lot, but as an example the person who’s post has now vanished was asking 10x what I’d pay. There is definitely a supplier of good elm near Yeovil and another near Andover

It’s readily available over the UK, I think most of mine came from Scotland originally but most suppliers have it and there’s is some cut in the south
