I've used photoresist from Ebay to etch a brass clock dial on 1.5 mm brass sheet. I used an A3 laminator purchased cheaply from Lidl and ran the thing through the laminator twice to make sure of the adhesion. It was exposed using the sun for about 3 seconds to get even exposure as I don't have a light box.

There is a good guide to doing the job here.

A couple of photos showing the developed resist and the finished product with the engraving filled with celulose paint:

Quite, all American lathes are specified by diameter as opposed to the British idea of specifying centre height.

The Atlas 618 actually has a 3.5 in centre height like the Myfords. It is a rather rare model in the UK as it was only sold in the US. You are much more likely to find the 5 inch centre height model10F in the UK as many were imported for war work and they were also built by a number of UK companies during and after the war.

Atlas lathes are somewhat under valued in the UK. They are very popular in the US. I bought my Atlas 10F in the early 1970s for £500 and would be lucky to get that for it now. It is like a big brother to the Myford 7 series, similar design but with 5" centre height, power cross-feed, and wider bed.

Old motors ran cool because the insulation available for the winding wire wouldn't stand high temperatures. Modern winding wire can stand higher temperatures so motors are designed taking advantage of that fact. Thus they are smaller and cheaper for a given power.

My old 1/4 hp grinder has a big, heavy motor and never gets more than slightly warm. The small cheapo grinder that I use with cup wheels and HH rest does get hot but has lasted for over 12 years so far.

Oops!

That used to be the case many years ago but now the French pouce (thumb) is defined as 2.54 mm, exactly the same as the Imperial inch.

The clock reads ten to only three twice daily but there was still honey for tea in the OrchardTea Gardens last time I was in Grantchester. Wonderful relaxing in a deckchair under an apple tree in the summer.

Ah, Dubonnet - still made about 10 km from here: **LINK**

I used Solidworks while employed but now, being retired, I use Fusion 360 which is in some respects better. However for quick small parts I use Onshape as it works under Linux as well as Windoze.

When working in Malaysia I tried Teh Tarik must say I wasn't impressed.

Thanks for that Neil. I have just ordered one, £59 including postage to France. Let's hope it does arrive before Brexit! Worrying times for us British expats.

It's not anything to do with the temperature of the water. If I pass water through the machine with no tea or coffee in it and let it cool enough to taste I get a very strong acrid taste in the water. I suspect it is a plasticiser leaching out.

I drink green tea, no milk, and when i visited a tea house in china I was told that the correct temperature for brewing green tea is 80 to 85C. I agree that black tea should be brewed at 100C.

Lipton's Yellow Label is just what you get if you ask for tea in a bar here. When I'm out I stick to coffee but at home I use Gunpowder tea unless I can find a decent Yunan.

I guess a Teasmade would be a better solution but they are not common here. Amazon.fr have one listed but at nearly €300.

I've been using a filter coffee machine on a timer for making my early morning tea for some years. A few weeks ago it died with a blown element so I purchased a new one.

The tea made with the new one tated terrible. I rinced the machine through with water several times and the water coming through still had a bad taste so I returned the machine to the shop and bought a different model - same problem.

After an internet search I came up with a number of possible solutions; run white vinegar through it, isopropyl alcohol, citric acid, or bicarbonate of soda solution. I have tried them all with up to 20 rinces but the taste persists.

Does anyone out there have a fix or do I just have to get out of bed to make my morning tea?

There are a series of PDF tutorials available from Autodesk here.

If it's still working, keep it. They were much more versatile than the ususal pop-up type. They will toast tea cakes, crumpets, etc., that won't fit in the slot of a modern toaster.

I broke a number of 12 BA taps until I discovered Rocol RTD compound. I've not broken one since.

Does anyone else here prefer a book to video tutorials? I find that watching video tutorials is a very slow way of learing. By the end of the video I forget the earlier parts. To follow one I have to have the video on my laptop next to the computer running Fusion. I then watch part of the tutorial, stop the video and try to replicate it on the live program, sometimes having to rewind the video and try again. Then I go on to the next part.

Following a tutorial in a book I can go at my own pace and also experiment with alternative methods as I go. It then seems to sink in better.

Not just Rolls Royce but nearly all motor cars made during the 1920s. Cost cutting in the 30s led to it being replaced by chrome plated steel.

May I add my condolences. I too used to enjoy his articles and found them inspiring.
