This is not the case.

The forum can't be used to promote commercial products or services, side-stepping paid advertising.

Discussion of technical aspects of commercial jobs or product development is welcome (as long as it isn't an undercover way of promoting a product), as we can all learn from such issues.

For example, it would be perfectly OK for a car restorer to recount how they dupllcated a broken part or filled creased bodywork with lead.

Obviously, if individuals would rather not offer advice to someone working on a commercial project, that's their prerogative.

Hi Tim,

It's not an oddity used by this website, it's a universal convention.

%20 substitutes for ASCII character number 20 hexadecimal (decimal 32), otherwise known as 'space'.

If you include a space in a URL it is treated as the end of the URL, so %20 stops it breaking and is automatically inserted by browsers etc.

Neil.

Did anyone suggest taking an impression of the corner using plasticine or blu tack, then selecting a drill that's a good fit in the impression?

Neil

I like the idea of a lever with a stop to lit its movement.

Please can everyone try to keep things polite.

FWIW my Imo Jaguar Cub (one of the most frequently sold to hobbysists) has built in EMC and so do many others. To comply the supplied grounding flange should be used to ensue the wiring is grounded correctly.

I just visit a single comparison website when I renew anything, on the assumption that going through many brings the law of diminishing returns into play.

My dehmidifier has a setting that claims to do the job of a tumble drier at a fraction of the cost.

I bought a cheap combined hygrometer/thermometer off Amazon, with 24hr and all time max/min functions. I later bought a 200W dehumidifier which has a built in hygrometer (so you can set a target humidity.

Positioned about six feet apart and at different heights, they both read consistently within 1% of each other which suggests that they are probably plenty accurate enough.

Interestingly, I found an old 'analogue' hygromneter, the kind that has a coated metal coil. I always assumed that these were pretty hit and miss, but it follows the digital ones within a few percent, always reading higher so if I adjusted it it would probably be surprisingly accurate.

On dehumidifiers, I spent a lot of time searching online and found this one which has vastly more features than other cheap ones (odour filter, hygrometer, programmable humistat, two-speed fan, supplied tube/drain port as well as built in receptacle) , and yet appears to be about the cheapest out there.

It can easily fills the tank overnight (useful source of 'distilled water' although I haven't timed it and now use it with a drain. It's actual energy use seems to average much less than 200 watts and it got the humidity down from over 80% to my target of around 75% in about a week.

I should say my workshop is well insulated and sealed, and although it's about 22 square metres the dehumidifier seems to work well.

To reinforce what Dave has said, please can everyone avoid personal attacks.

There is an 'ignore member' button available and I suggest using it rather than getting into scraps.

I don't want to have to start the New Year with locking threads.

Also, sometimes people make statements or share content that has elements some people may disagree with.

Yes, it is reasonable to point out things like missing earths or cables draped across machines etc. but equally we need to be aware that most photos don't tell the whole story. We also should avoid turning comment on one or two issues into a checklist of minor niggles.

Neil

Can you share a photo Rik?

I filled a 5-yard skip...

In the good old days, a skilled fitter would file a dovetail for a plug of cast iron to fit in, then hand file the teeth.

They don't look like silver brazing rods. Too large and wrong colour.

They look like copper.

Only one Saffire rod contains antimony (Sb), and they would appear useful to a plumber/pipefitter:

I started with a Marina in which the direction of travel was only loosely correlated with the steering wheel, especially in the wet. Other cars included a Manta, an RX7 and a Honda Integra - and my ex-wife's Astra GTe and stepsons MX5. I think they were all fun to drive.

Other cars were less inspiring, although many were 'nice to drive' and the Cortina Estate with a twin Weber and low ratio rear diff was a fast car off the line .. until it reached 30.

I'm all boring and sensible now, with a big, comfy, efficient but somewhat underpowered Citroën estate.

So probably, the same as you Peter!

I found a magnetic toolholder, on the wall behind the mill - vice handle, ER spanners and the tommy bar (when and if I find it!)

When I set up my mill the X-axis DRO wasn't working properly. Had to resolder the hard-wired connection I fitted. Still wasn't right, so I left it unpowered overnight and then in the morning it worked.

Not until after I'd ordered a replacement read head from Machine-Dro... still it's useful to have a spare.

The only machine in commission is the bandsaw, which has been cutting M10 and M12 studding and screws to length for use as machine and vice fixing bolts.

Lots of other 'stuff' all muddled up with the the useful engineering bits. Some is useful, some is of dubious utility, to me at least. So far I've found three working (but ancient) Nokia phones as well as two Motorola ones... Some of this will go on eBay I fancy.

The awkward stuff is things like cocktail sticks, cotton wool buds, shims, fixings, fuses and an infinity of adhesives and lubricants. All worth keeping, but they have to be found a sensible home. As well as putting things in 'to sort' boxes - HO railway, musical instrument bits, astronomy bits, photography bits, miscellaneous cables and wire... And a huge amount of 'useful' metal which ranges from proper bar stock of known composition to bits of broken vices and enough brass oddities for a few episodes of Bargain Hunt (such as a 2" long boot and a table bell shaped like a Welsh Lady).

I managed to pick up a big set of Braziilian made Dormer split-point (in the larger sizes) drill bits, by 0.5mm up to 13mm.

I won't say 'I will use no other', but I do keep them for all the critical or demanding jobs.

Neil

A free classified ad (see the green stripe) will be more likely to find them a home.

I think Jason is correct, at one time Little Machine Shop (IIRC) in the USA were selling Mini lathes with 'Tru-inch' screws. The digital units fit new screws.

In practical terms, the difference with standard 1mm pitch screws is small enough not to be critical over short distances. So if you need to take a cut of (say) 20 thou then half a turn is 0.0197" close enough to 0.020" for practical purposes.

As you make bigger steps the errors get bigger. Actually, as it underestimates the distance (by 0.4mm or about 0.016" over an inch) the sensible strategy is to use the scale, then measure the actual size achieved. It will be over by some small amount which can be dialled in without worrying about the error.

This is a sensible way to work anyway - approach 'size' then take a small finishing cut.

Don't forget (1) when working on a diameter the cut you need is HALF the amount you need to remove and (2) unless you have very sharp tools light cuts may remove less material than you expect (a second or even third pass over the work will usually rectify this).
