Wot 'Eee said ^ ^ ^

That is NOT understanding at all. This is an AC circuit at mains voltage and you are quite wrong in your assumption. Be very careful: you are dealing with potentially lethal electrical parts. I strongly recommend either reading up on AC and motor theory (via t'internet - Wikipedia or similar...

Unless, like me, you don't really have fine motor control any more in your hands. My fingers no longer bend in the right, normal ways, either. Then a jig is very helpful indeed.

I have a pair of skews: I only ever need them very occasionally for that last tiny bit in the corner. They're re-ground 1/4" chisels from Bristol Designs's odd chisels bin - bought totally blunt for their length and reasonably good handles. I think both together cost me about 15 quid. The...

A very kind offer Andy, but it has apparently found a new home with another forum member. I had a PM waiting for me this morning. I'll miss it (but not the forehead bruises)! E. PS: I have looked all over it during my semi-restoration some years back, and although there is a serial number...

If you ever thought a tablesaw without a riving knife was dangerous... at least you'll probably get a 'spare part' that could be sewn back on with this machine, but in every other respect it should be considered terrifying to any living creature with opposable thumbs. That said, this guillotine...

Bob, it's different in somewhere like Cyprus that gets far more and stronger sunshine than we do here: in order to work, our panels have to be more efficient, so the channels in the panels are much smaller (I know the sort of systems you describe - they are ubiquitous throughout the tropics...

There are two generic designs: drainback and fully pressurised. The drainback has a reservoir tank, In the event of boiling temperatures in the panels (or freezing), the circulating fluid drains back and is stored until conditions change. That's what we have. It has one standard CH pump, a...

Nobody has mentioned the power wasted in energy conversion inefficiencies. It was a big reason why, years ago, I opted for solar water heating, rather than photovoltaic panels. We have aboutr 8m^2 and in the summer (when it's working), there's little need for any extra heat input (6-bed house)...

At 5AM in the winter, my toast burns. It doesn't happen later in the morning. I think this is because the grid is boosted to anticipate breakfast demand, and the voltage settles back to normal after a while (and the kettles go on). So what John is experiencing is the opposite of what I would...

That's a shame, but a repair may be inexpensive - quality bearings don't cost a lot. If you can dismantle it, the bearing size will be stamped on the outer rim of the bearing (one of the flat faces, I mean). It will be a standard, and you can get various grades of replacement. The first part...

Something is out of balance, and/or the main bearing has failed. It's odd, as normally motor armatures are balanced by grinding away weight, not adding anything that can fall off. Shaft: Has it been dropped at all, so that the shaft might be bent out of true, even slightly? Do you have a dial...

Similar experience here: I now use a Rohm keyless chuck (very similar to the one on eBay above) for small work - it is brilliant. There is one issue though - it tightens (centrifugally?) as you spin it up, so you have to remember not to overdo it when locating the drill bit, otherwise it...

I'm posting this only because it informs what is becoming quite a heated debate. I don't have a firm view either for or against SawStop as a technology, although the current owners of the intellectual property seem to be rather agressive in their defence of their IP. I have, however, always...

Regarding the small Lidl pull-saws, I have one and it's great, and one big advantage is that they are sharpened/ground nicely for cross-cutting. The Crown Tools one I have was apparently sharpened for rip-cutting, which is a bit silly for trimming dowels (supposedly what it's intended for). To...

Uh... OK, I see they describe them as Forstner bits, but wouldn't be what I would immediately think of. I checked: my Colt set does go down to 3mm, but I don't think you gain much advantage from thegrind at that size. They're these (Colt "Five Star")...

Mine was pretty blunt when I got it, but a touch-up with a diamond needle file sorted it. Might that be the issue with yours, Jacob?

Are you sure of the diameter? 19mm is very nearly 3/4", so could it be an imperial shaft? If so there ought to be a lot of options available. Perhaps ask this in the metalworking section, but meanwhile have a look at Chronos's web site. They cater for many types of prototyping, including...

Do such things exist? I have a feeling my really posh Colt set only goes down to 4mm, and those are more similar to lip+spur (although the tip shape and grind is quite different). I know you can make lovely crisp 8mm holes in hardwood, but the 3mm one gives pause, especially as something is...

I have a nice British made Crown Tools one. It wasn't expensive (<10 quid, IIRC). It has set on only one side, and it is flexible and resharpenable, if you are careful. It doesn't scuff like Japanese saws can (they have a tiny set on both sides). I had to mark the handle to indicate which side...
