I wouldn't describe a nut having a serrated flange as a self-locking nut, Howard. They're very easy to undo, even if they can leave marks on the surface of the clamped material.

Grade 10 BZP flanged nuts [DIN 6923] are usually smooth rather than serrated. You might prefer that.

The black oxide flanged nuts that come in 58 piece clamp kits are usually non-serrated as well, and their height is usually more generous to get a spanner on, but still not as generous as a DIN 6331 flanged nut.

Unfortunately, DIN 6331 nuts are very expensive compared with the DIN 6923 variety.

You've probably got limited space behind the chuck, though, so extra nut height won't be wanted.

This is decent quality [I've got several Sherwood die stocks and tap wrenches, as well as many Sherwood dies and taps], though it's bound not to have everything you want.

Sherwood [aka Kennedy] die stocks, bought in sets, are a bargain price at the moment.

Yes, not sure why the blocks are there.

Have you tried doing the test [directly on the table preferably] at various points along the table and compared readings?

The ChatGPT poem is about equal in merit to one of William McGonagall's.

"However, the reason why phishing emails have so many typos is simple—they’re intentional and are included by design. The scammer’s goal is to send phishing emails to a very gullible, innocent victim. If they have typos, they’re essentially weeding out recipients too smart to fall for the scam."

​​​​​​​The logic of that defeats me.

And whatever logic it has is subverted by the comment in the next paragraph:

"Sometimes, the sender might not speak the language they’re writing in, which explains typos, grammatical errors and strange phrases or sentences."

The B12 is for people with an existing B12 arbor, the B16 for those with a B16 one?

From the the wd40.com webpage titled "Myths and Fun Facts about WD-40":

"A QUESTION OF LUBRICATION

Myth: WD-40 Multi-Use Product is not really a lubricant.

Fact: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal."

Weekly wiping of my milling table with WD-40 has resulted in zero oxidation on it after three years in an unheated west-facing garage. The same cannot be said for other iron and steel objects in the same garage that have not been wiped with anything. If I want better protection against corrosion I use Waxoyl, but I don't want Waxoyl on my milling table as long as it remains in regular use.

Shown below is how Mac Industries [I have no connection with them] create a welding table surface that is likely to stay flat:

Apologies if this has been discussed on here already, but is there no longer free UK postage at Arceurotrade on tooling etc. if your basket price is above a certain threshold?

I think the threshold used to be £75.

What did you unscrew it with now that it was a round hole rather than a 2.5mm hex socket?

I don't know whether you were lucky, but the relatively small size of the fastener may have been on your side in responding to wallops from the hammer more obligingly than bigger fasteners might.

It doesn't look rusty either, unlike the M10x1.25 lawnmower blade bolts I had to remove recently, which needed the highest setting [reputedly "1625Nm of breakaway torque"] from a Dewalt DCF899HN-XJ 18V impact wrench to come undone.

Though the brand appears to have a few challenges to overcome if it's to retain its market share.

Assuming your review was less than 5 stars, Michael, I'd say the current showing of only 5 star reviews for every single kind of drill bit on that site does not augur well for your own review getting an airing there.

Worse, the wording used in a worrying number of those reviews smacks of fakery to me.

This is one video that certainly doesn't find Timeserts to be stronger than coil inserts, although one flaw in the video as I see it is that the demonstrator is tapping all the samples by hand; as a result, some threaded holes will no doubt end up closer to perpendicular than others, and this may influence the holding strength of the female threads under test.

That's a shame, Michael. It's not at all what was advertised. It's a standard profile drill, from the look of it, but with a very thick web.

If the item is at all fragile, I'd rather have more packaging than less.

Amazon went through a phase [possibly still ongoing] of minimalist packaging, called "frustration free packaging", otherwise known by me as protection-free packaging.

I lost count of the number of books I had to return because they were damaged in transit. Even a set of books weighing 10kg and costing £180 were sent this way - and damaged.

The loss to Amazon of such returns is probably trivial in comparison with the cost savings, across the whole business, of reducing packaging time [and materials] to a minimum.

Dewalt, who are Black and Decker, still sell them. They're described as a cobalt drill, unlike this particular Ruwag offering.

Here.

Not sure how you're measuring the pitch, and why you've given two different readings for the major diameter and pitch of the "3.5mm one", but, as others have said, these are most likely to be 2,4, and 6 BA screws.

4BA was used instead of M3.5 on older electrical sockets.

Obviously we don't know what your bar stock is/was, but could you just clarify what you mean by "silver solder"?

Comsol has some silver content.
