It could be worse, it could be Ben Dover.

Make sure to visit the workshops and the roundhouse.You certainly won't be disappointed.
|Thread: Q-Tech Collet Chuck|
Sorry, no, I haven't used one. I found it when looking for one similar to the Eclipse version that I purchased a few years ago, which works very well and cost only about £12, but it's maximum opening turned out to be 33mm.
For the sole purpose of tightening an ER30 nut I would think it would be quite adequate.
**THIS** will almost certainly do the job for you, and cheap too.
|Thread: Interesting bike ride today|
Way back in 2006 my wife discovered two tiny bats 'swimming' in the WC. The sash window was open an inch or so and has a lace curtain. It seems that the bats had been able to push the curtain inwards, but were unable to push it out when they discovered their mistake. They fell into the WC and couldn't get out again. My wife opened the window and used a towel to provide a ramp for the bats, which she then placed on the window sill. When she told me what had happened I went to look, then decided to get my camera. By the time I got back, one of the bats had flown away, but this rather bedraggled one remained. 30 minutes later, it too had flown away.
|Thread: Trembling laptop|
Trembling is a better description of the sensation than tingling. It's extremely slight and is eliminated if more pressure is applied. It's definitely a mains frequency. I'm told that not everybody can feel it, but my wife is also able to detect it. The screen has a metal bezel but the the trembling is not apparent on it; it's only apparent on the metal cover around the keyboard/touchpad.

***This*** makes interesting reading.
|Thread: Trembling laptop|
Thanks for all the useful replies. I couldn't try a different charger but, encouraged by the optimism of your replies I spoke to a local PC repair shop who agreed with all your responses, but nevertheless suggested calling Lenovo, which I did. I'm now encouraged to accept that the trembling is very common and nothing to worry about.
I've just purchased a used laptop - a Lenovo IdeaPad. It works perfectly, except for one rather worrying thing - when I gently brush my hand or finger on the metal panel surrounding the keyboard I feel a very slight trembling. If I unplug the charging unit the trembling stops. It's clearly a mains frequency trembling. The charging unit is marked INPUT: 100V-240V~1.5A 5-60Hz OUTPUT: 20V = 3.25A. The '=' sign is actual a horizontal line above a horizontal dashed line.
Does this signify a serious fault or am I a little paranoid?
|Thread: Unkown plastic|
I tried the hot needle test and the fumes were certainly not acrid. Not unpleasant at all really. So presumably not Crystal Styrene.
Are there similar tests for the other suggestions?
My wife has an empty cosmetics jar. It's quite small and looks and feels very much like cut crystal glass. The fingernail test says glass, but the tooth test says plastic. Any idea what it could be?
|Thread: Amazon Prime scam?|
My phone and internet are from TalkTalk, both of which work fine. The phone has an optional, free, call screening facility. Calls from whitelisted numbers are passed normally, all others must state their name which is passed to me when I answer. I can then whitelist the number by pressing 1, accept it this time only by pressing 2, or rejecting it by pressing 3. Since using the service I've had almost no spam or scam calls.
As a teenager in the 50's I remember a shop sign (outside a tailor's I seem to remember) that said 'Quality is remembered long after price is forgotten'.
|Thread: Broken drill bit in hole|
Sorry to disappoint. Making small tube is not difficult, just time consuming.
I made the tube from 0.5mm sheet, which I first rolled down to 0.25mm and cut a strip just a little wider than the circumference of the required tube. I cut one end of the strip into a 'V' and then used a swage block, and a series of suitably sized rods, to bend the strip lengthways into a 'U' shape. The end of the 'V' was then poked through a suitably sized hole in a draw-plate, and then pulled through to start closing the 'U' shape into a circle. Smaller and smaller holes were then used until I had a hollow tube - albeit too large an OD - which I then soldered along the seam. I then used smaller and smaller holes in the draw-plate until I reckoned it was just right for inserting the iron wire. With the wire inserted I could then continue using smaller and smaller holes until it got to the required OD. After a final annealing I could then coil the tube around a former to make the required helix.
Acid then got rid of the iron core.
|Thread: Centering Microscope|
When I was in my teens, and blissfully unaware of the problems, I dismantled a pair of binoculars to clean them. Even now, many years later, I well remember the frustrating days I spent re-aligning the prisms. But I eventually managed it.
|Thread: Broken drill bit in hole|
Using pickling acid will certainly do the job without harming the copper. Heat it up to speed the process.
I once made some earrings from 1.5mm OD gold tube. The tube was made with a core of 1mm iron wire to support it when it was coiled to make the helix required for the earring design. The iron core was removed by immersing the helix in 10% H2SO4. I had to heat the acid, but it still took about 2 days to remove all the iron.

Here's a test that might be of interest. The yellow spot indicates a tangent.
My effort was done with Fusion sketch. What's wrong with it?
