Sorry Norman...but then, you don't know what else is going to be in that issue...

For the benifit of the person that has been following my series of articles on the Cowells lathe renovation project, you will be glad to know that the final article in the series was sent to DC for processing on Friday, so it should appear in a copy of MEW near you in due course. This article deals with cutting the gears for the finefeed train. As a taster, here is the end result:

The finefeed now works very nicely!

Certainly more expensive, but the 200mm cube build volume is considerably larger too.

Yep, Coke works just fine, and probably Pepsi too - basically dilute phosphoric acid with added flavourings and bubbles. I wonder if this is how they make Irn Bru...?

There are other similar (to the patio cleaner) products sold for cleaning grout and cement residue off tiles/slabs - there's one available on Amazon for £14 (£3/litre) that is 36% hydrochloric acid which would need rather more dilution before use than the Cmentone one (which looks to be 5-10% as far as I can tell):

Paul -

Not that I needed much persuasion, but seeing what you have produced has convinced me that I need one of these! Even if you plan to make the parts by hand, in metal, for the finished article, the ability to prototype relatively quickly in plastic to see how the design fits together looks very useful indeed - a great addition to any workshop IMHO.

This is very sad news. I first got to know him through writing articles for MEW when he was Editor; as others have already said, he was a true gentleman, always kindly and helpful, and with a warm sense of humour. He was a major asset to the model engineering community, and will be greatly missed.

My condolences to Gill and the family.

I usually buy apples in bags, not tins

Stuart -

Firstly, whatever you may think of the Chinese, there's no excuse for referring to them with a derogatory name. I'm surprised the moderators haven't instantly banned you for that - if I was a mod in this forum I certainly would have.

Thirdly, with no source of decent UK-made iron these days, with the possible exception of niche manufacturers like Cowells, you have little alternative but to buy machines of Asian origin, so get over it.

Actually, the point of sealed bids in gvt/local council dealings is to prevent corruption - council employees reading the bids & feeding back to their mates so they know what the competition has bid. The Ebay situation isn't the same at all - even if the auction isn't private, the bidders have no idea of the identity of their competition until the auction ends - only the seller can see the identity of the bidders while the auction is in progress.

Where you messed up was failing to bid your own personal limit in the first place. If you treat it as the type of auction that you seem to enjoy bidding at, then you will continue to mess up in exactly the same way. With ebay, *because* there is a time limit, you have very little scope to re-consider when someone out-bids you in the last few minutes/seconds. So the only answer is to place a bid, before the end time, NOT for the amount that you hope in your wildest dreams you might get it for, BUT for the top price you would be happy to pay for it. That way, you don't end up moaning because you lost the auction or because you over-bid in the last-minute frenzy.

I'm sorry, but your distinction between "real" auctions and Ebay is spurious, to say the least. I would be willing to bet that more items are auctioned on Ebay these days than in all of what you call "real" auctions - so which is the real one?

Any auction operates under a set of rules. The rules for Ebay auctions just happen to be different from the rules that operate at Joe's Auction House down 't road, which in turn are different from the rules of a Dutch auction, or your local livestock auction, or the rules that operate in the Tokyo fish market tuna auctions (a fascinating spectator sport, but you have to be up well before sparrow fart to catch it! Lots of videos on Youtube).

If you want to use Ebay, figure out what the rules are, and then use them to your best advantage. There are lots of winning strategies - John S has described one that is very effective, David C has described another.

But please don't whinge about it not being a "real" auction - it sems to be "real" enough to be the biggest auction house on the planet.

I think the problem is that the newer ones are made with 50% horse meat

There's a useful discussion of accuracy and precision here:

http://en.wikipedia.org/wiki/Accuracy_and_precision

Which demonstrates that "precision" (a measure) is often and incorrectly substituted for "precise" (an absolute and non-achievable goal).

All vices are precision vices; however, any particular vice may or may not have the precision that you are looking for. So a useful definition of a "good" vice would be one whose precision meets or exceeds the needs of the task that you have in mind for it.

...and I didn't read it as such; it was a helpful, well thought-out and well expressed post IMHO. But as you will no doubt have discovered, you can't win in this forum - whatever your intentions, someone will choose to mis-interpret them.

Best brush up on your geography - last I heard, Prague was definitely in Europe. But then, I guess xenophobia is no respecter of borders

Just to get the thread back on topic...

I don't give a TOS about Norwegian keyboards, peculiarities of brackets, or peoples' preferences with regard to smileys.

As far as I am aware, only the Griptru chucks are still manufactured in the UK. My industry informant tells me that TOS makes P&B chucks these days,

Not entirely surprising given the apalling state of UK investment in manufacturing over the past couple of decades - the up & coming manufacturing countries have invested in the latest manufacturing systems and as a result can manufacture better quality for less.
