Sorry i'm using weld out of context, I've actually hard soldered, I can show pics of that but not true welding I suppose.

I needed to fix a lampshade where the ring had come off it, so I cut out a mild steel ring with square two lugs, which I rolled each of into a tube shape with some pliers, little gap left at the top for solder and around the sides, fits beautifully now.

My propane burner flame would've been too hot (over a large area, because the nozzles are chunky) and burnt the material, which I covered to protect it. The little flame was perfect for it and very hot.

I have used it to cut through (gas axe) 3mm mild steel, you need goggles for that though and it works. So I presume it could weld?

Could even put up a video if I knew how and show you it cutting through a piece of scrap!

I'm half way through my twenties exactly, i'm not averse to imperial if I must use it, but I can definitely understand it!

Not all the young'uns can be measured by the same yard stick

I'm not sure how big the welding is you like to do Andrew, but I find that although I want the benefits of gas welding, I don't want the fuss of having to store big acetylene and oxygen cylinders, the former being one of the hottest burning fuel gasses in the world!

So I bought the small welding kit sold by CuP for a few hundred notes, but it's perfect for me because I already have propane and I use it for small jobs, MAPP gas being a much safer gas to have around, and not so much of it in smaller disposable canisters that you can buy again from them, I'm still on my first after 6 months or so.

Again, it may not be relevant to your cause but it's just what I use, no connection to them whatsoever, other than being a customer at least.

Nice to hear from you again!

Hear, hear! I think this sums up the situation admirably, it's our language just as much as theirs.

Very cool, I think it would be rather churlish to suggest it was anything but engineering of sorts to be honest, deserving of respect!

The sherline uses threaded chucks too, it's not designed to reverse but I don't seem to have noticed any detrimental effect with regards to run out.

I believe in 1948 there was an international agreement between the U.S and U.K to tie up their systems so that you could easily switch between the two.

If you consider the fact that the U.S (13 colonies) was a colony started by and large the british as well as governed. With the capital in Virginia as opposed to Columbia like it is now. They are kinda using the same system. and even more so when you consider the above stated.

'The British Standards Institute defined the inch as 25.4mm in 1930 in the document "Metric Units in Engineering: Going SI". In March 1932 the American Standards Association were asked to rule on whether to adopt the same value (at the time the American inch was 1/.03937 mm which approximated to 25.400051 mm). Because the values were so close, and because Britain has already settled on that value, the ASA adopted this value on March 13, 1933.'

​​There was apparently a Scottish Inch at one point too. One might say that the units themselves, pertaining to latin in origin, are older than the term for the whole system. And hence why they crop up in pre-metricated European nations too.

Whats wrong with 1 phase? Plenty of gearhead lathes use 1 phase clutch motor.

Has anyone tried to convert a belted lathe to a gearbox style start with quick change speeds/ratios?

Michael W

Yeah it is interesting, I'm sure they flout the law by edging on the side of technical legality, i'm sure if there was a place doing that much business but in drugs rather than scams they would get piled on like a ton of concrete from the police.

lol, well I think I got the wrong name for it, it's more like a brass, **LINK**

Michael W

Lol

I think that one's fubar now.

The pin and the plate around it were assembled incorrectly, when they peen the edge of the pin round to secure it, they probably end up creating a stress/fracture point by hitting it or too much pressure.

Are you sure he didn't buy it from Axminster, Nick?

They do this to everyone, it's not good enough to just want to be left alone anymore!

Slightly unrelated, as i'm not anywhere near Scotland. But I would definitely count the advice given by CuP to have been a vital part of my education in brazing.

I can braze virtually anything with a certainty of knowing that it will work. Even with 60/40 silver solder! It's all in the preparation. (Specifically, I didn't know that I was using the wrong type of flux until I read CuP's advice page). 

Thanks!

Ooh, trolling

Too right, that thing could kill you at those sizes.

People might think this is just a rare happening but I know of someone who was killed trying to turn a very large piece of wood that was thrown out.

I would seriously consider staying well away from the stated maximum speeds, you're not quite sure under what conditions or work piece they were using with it. I don't really get this obsession with speed, there's no reason why it wouldn't turn at a slower speed.

I have been known to rough steel with HSS taking 4mm deep cuts I'm not impatient, honest!

A fact is the subject of a majority opinion, confirmed through practice and time, the expression "alternative fact" really annoys me, because it's just a fad word for falsehood.
