|Thread: Interesting YouTube Video.|
Found this on YouTube this am. New to me.
|Thread: Phosphoric Acid experiment|
Ok this is probably of little interest to anyone but nonetheless
Have this old fragment of (what now appears to be) wrought iron. Been using it for years to open paint tins, lever out nails etc. You know the sort of thing.
Recently decided to try clearing rust off a section using Phos. Acid. (light grey area in above photo)
24hour immersed in acid reveals interesting striations in the structure of the metal - once the rust is 'dissolved'.
(I believe this is consistent with old wrought iron)
Will probably do some follow up exploration on this. Should it be of interest I may post more photos.
|Thread: Another mystery object|
Looks like a saw set.
|Thread: Electrical outlet search|
The picture is a clip from a background of another picture. It's all I have.
Michael - made me contemplate rewiring then entire shop in the manner of a stage set - which might actually have merit.
DC31k - I know.....sigh!
Why is it that
Regarding the item picture below:
What is its correct name / description? (google return no match for either image search or misc. word combinations)
Are they 'retired' or readily available?
I have been searching for such for some time.
|Thread: Don't really know where to Topic this.|
|Thread: complete engineers workshop|
|Thread: Good YouTube videos|
Tim's Railway (featuring on his "Way out West " channel) is, at least to my mind, an interesting and engaging look at a real world 'farm railway'.
Some of his other projects make worthwhile viewing - the exploding boiler episode is - sobering.

|Thread: That Strange Calculator Again|
... and they appear to do so when the 30 & the 0 are in alignment.
Also he detent spring would appear enabled to engage, or lock, both dials at the point of alignment.
It's not clear (to me) if this applies to both 0 points on the outer dial.
Quoting from the original reddit posting "Both rings rotate clockwise freely but lock in this position when rotated counterclockwise." (see Reference earlier in thread)
"...this position..." is a bit ambiguous but I am assuming that it is the home position of the apparatus i.e. 30-0-0
|Thread: Is it possible to machine a lathe more accurate than the one you machine it on? If so, how?|
The following, perhaps not directly relevant to OP, but......etc.
|Thread: Multi-dimensioned Drawings|
Perhaps one of these!
|Thread: WHAT IS IT ?|
The scale appears to be a lacquered surface - on either a cork or wood substrate - (sector 4 top of your clearer picture)
I'm not entirely convince the outer dial rotates - appears fixed by at least 3 rivets - ergo the only moving part is the inner dial.
So a lacquered scale and a 20 hole 'dial' both fixed to a rear plate. (the 20 holes being divided into two sets of 10 - for some reason)
An inner rotating plate with 30 register points.
Speculation - rotating the register plate will align a number on that plate with and a number on the outer dial at only a limited set of locations. Information is read from the relevant sector.
Hopefully someone won't ruin this by coming up with an answer.
If you have the physical device........
Would it be possible to re post the photograph showing the device next to a rule.
Alternatively post some dimensions.
If not above possible would anyone hazard a guess at sizing based on limited information.
|Thread: YouTube stuff....|
Apologies if this is redundant post.
|Thread: Does old meths burn less hot?|
My understanding is that they only harden in the absence of air enhanced by the presence of metal ions.
The presence of 'air' (oxygen) in storage is necessary to NOT harden.
They are (mostly) single component fluids of large molecular size - so low volatility.
The technicals appear to be endless.
|Thread: Design of boilers|
Actually does sound like a great challenge or a new category!
|Thread: water level sensor|
I'm intrigued - how, what etc??
What software is that?
|Thread: Newcomen Plans or kits - looking for.|
Thanks to all who took the time to reply. I appreciate it - it all helps.
As I understand it this is the engine that started it all - however its inefficiency somewhat limits its scope.
Nonetheless one can't help but wonder if a multi cylinder version is possible or perhaps it could be harnessed to enable one of those horseless carriage contraptions that are all the rage.
I could/should tackle it from first principles but laziness whispered that a kit would be a quick fix. I think I will have a ferret through my junk box and see what might be possible. If anything promising emerges I might report back.
Could anyone recommend a source for decent Newcomen Engine plans or better yet a good kit. There is some stuff out there but .... a bit wanting.
Ideally I'm looking for something that clearly illustrates the central principle & operation of the engine rather than a strictly historical recreation - not sure if I explain that clearly.
Thanks in advance for any help.
