Well tried it on the other systems and on every combination of OS and browser it automatically corrects http;// to http://

Just all part of life's rich pageant (As Inspector Clouseau remarked on getting out of the pond again )

Michael - I only realised there was a typo in the original post after posting the link again, but what puzzles me is that I only knew it was wrong when ega pointed it out as even with the typo it worked OK in Edge on Win10, I have just tried Chrome and IE on the same m/c and Safari on the Mac and on all of them it corrects the mistake and loads the page fine, as it does in Android on my phone.

I have not got a Firefox, Chromium Pi or Linux machine up here but I am intrigued so I will check them when I go downstairs, just for my own satisfaction. As the saying goes - To err is human, but to really screw it up just get a computer!!

Take care,

Nick.

It must be hard to dismiss it as just paranoia when they are sending fast jets out to get you ............. 😀

Neil - wouldn’t a hole higher up the steady move it towards the lead screw not away??

My Granddad had some American spanners in his shed that apparently came from his time in the RAF in WW2. He said that when Merlin engines came from this country you got an engine, but if it was a American built one it came with a full tool kit and spanners - presumably because of this incompatibility. (real or imagined I suppose)

Because each and every US engine came with the tool kit everyone in the hangar ended up with one when the F/Sgt wasn't looking!

Thanks for that link Martin - it clearly shows how a tool in a rear tool post or upside down in the normal one 'springs' away from work as against 'jamming' when set up in the normal way better than just using the words as I did. A picture says a thousand words and a youtube video can often be even clearer!!

It is a shame that the computer simulation shows a tool so far above the centre though, as that makes the problem bigger than in real life.

Geometrically the front and rear parting tools are pushed in the same relative direction compared to the rotation of the workpiece.

What prevents the dig in is the 'spring' when a rear parting tool is pushed away from the lathe bed as against the 'jamming' of the tool between the work and the rigid lathe bed.

Another advantage of the upside down rear lathe tool is that chips fall away from the cutting edge of the tool.

When I was very young a mate at primary school had an imported GI Joe toy and together we made an aqualung set for it using the identical cylinders, but that had held CO2 for a soda syphon.

Got an Action Man as soon as they were launched in this country (UK) but my mate reckoned his imported GI Joe was cooler.

Thank you for the video link - really learnt a lot.

In a similar situation to the museum I have see threads used on linen and paper presses and the buttress makes sense, but the 0.7" is surprising.

Please excuse my ignorance on things traction engine, but is this method I have seen used in model engines of bolts through hollow stays not used in the full size?, and by extension is an accurate model not permitted if it is to meet the Australian code?

While plate thicknesses and joining methods might well need to be adjusted to make a safe working model, if I have understood this correctly, does the visible structure have to be changed too?

Interested to know.

Totally agree either will work and that it is easier to replace a piston, but if I remember my tribology lectures from nearly 50 years ago correctly, it is the harder material that is expected to wear as particles of the harder material become embedded in the softer that then lap the harder one, wearing it more.

Thanks - and Andrew I envy your perseverance! Thank goodness none of my current projects include so many large rivets!!!

While I totally agree with you - the issue is that a commercial LED bulb consists of an LED light source and the electronics to drive it off the mains - and you cannot 'get at' the LED itself. You need to use a dimmer designed to dim the electronics not the LED as has already been suggested.

In the first instance copper, although I can see a future need for soft iron/steel, so I was planning ahead and trying to avoid remaking them in the future

While not relevant to a lathe, at least hopefully!, just because there is a BSF/BSW head size on a bolt does not necessarily mean that is the thread - Morris at their Coventry (ex Hotchkiss) engine plant used metric threads with BSW heads on Morris engines until 1954 and even later on MG and Wolseley engines!

One of the nice things about the G5 is the 13Mp camera - I was surprised when I recently upgraded to the G7 that it was only 12Mp. A better phone but a lower spec'ed camera.

I only upgraded because the screen on the G5 was being heat damaged near the switch.

PS: A Dad phone? - That's not what my two 20ish daughters call it...………. !

ArcEuro sell the Shield Technology products - never used them to protect anything personally, but it might be worth a phone call?

I need to make a couple of narrow 1/16" rivet snaps to get into awkward places.

I was going to use silver steel and harden it out, but in water or oil? And what to temper it down to?

My only previous experience in similar heat treatment has been when making small reamers out of silver steel - but these were left hard.
