Thread: Looking for an acid supplier
19/01/2014 19:37:06
Sorry jerry..I'm with oompa..lead acid batteries. .out gas hydrogen and a less than stoichiometric ratio of oxygen (certain amount of recombination goes on at plate)..and the acid. used is sulfuric..H2SO4....you only get HCl out of batteries if you let salt get in there ( ask any diesel electric submariner)


Another clue..bad lead acid batteries are definitely suffering with sulphur ( aparrently sulphur is spelt sulfur now...who knew)

John has highlighted what is often said that the digital portable version is useful to us..
And also serves to restate that poor quality "bootleg" copies not only deprive the author/publisher of revenue but compromise the perceived quality of the original

Raymond..I too wondered how much photoshop and so forth..also what kind of builder would build some of those regardless of plans......so funny yes..convincing no.
I have seen some corkers in things like the bridge one but it beggers belief that it wasn't noticed earlier....
But Nasa managed some sort of ( according to myth) units error which resulted in amulti million ( billion ? ) $ space vechicle reaching mars at a much higher velocity than expected...think the impact crater is still there.

Thread: forming a thread on piano wire

Thead rolled threads are much much tougher ( in the right material)
than cut threads. .think forged..and if possible in piano wire..would yield an extremely durable result..

Those bike rolls. ..mmm wonder what they would do on titanium spokes

Martin ..I have seen that too.
Also saw a broken plane casting taken in to be repaired...job returned..oh that's nice. .can't hardly see the weld...sorry mate couldn't weld it we copyied it and sparked it out of solid...
The had copied it down to the sand marks off the casting. .including chips in the face of the plane...not daft but smart ar (*.

I offer two thoughts

Noah built the ark apparently to some one elses design but with no prior experience

An experienced engineer designed the Titanic , it was built by time served craftsmen

(It has been argued that accountants then ruined it by cutting corners but there you go)

Now the other thought is that the titanic was not the engineering disaster of popular myth ..it took a massive hit ( completely unprecedented )
..it sank over a quite sufficient time to allow all to escape to life boats if they weren't looked below decks and if sufficient spaces were provided and if class/culture had allowed better use of those available. .
In short yes a disaster but not of engineering in origin

The post above reminds me of one the new grad.s I had to puppy walk.
The problem posed was how many 0's 1's ...9's would be needed to ident a cable harness between
Two different wire numbers. Ie between say 12300 and 12567
Ok says puppy and goes off to derive his algorithm. ..after about a week (!)..the DO gets onto me..still havent got that answer....so I enquire..nearly done just got to test it...test it? Thinks I
..mmm best work out how to check this. .so half an hour latter I have a brute force programme to do same..but much slower. .we check puppies almost instant programme against my ten minute chugger ( note bashed in in half hour)..suitably "proven" with minor tweek this programme was issued to the DO for use.. ( turns out they had a total of 100 cable sets to enumerate ..sigh).
.now 100* 10 minutes would have got the job done in the first day..


And the minor tweek...wires have two ends both requiring idents....
Thread: forming a thread on piano wire

Or grinding. .
Piano wire is most certainly not homogeneous. .drawn many times and many of its properties are "work hardening" ( may be no such word but clearly such a behaviour )
Cutting /grinding /eroding through the outer layers will yield even without heat treatment a very different material behaviour.

Not for the first time, this morning I woke to find the elves that make this forum work have been in action

Rather than clutter up the thread in question ( and in the future others) with a note of thanks
I start this thread and thank in particular JasonB. For correcting and thus restoring some sort of flow to a thread.
And again thanks to all mods for your actions that make this work. ..

Mmm..is this like showing how hard you are buy wearing tee shirts in the winter...
" I am a better model engineer because I didn't go to university.." sort of thing...
This has been discused in the Engineer at some length.
When the plumber who fixes your central heating ( because you aren't allowed to... not gas safe registered) is called a central heating engineer but doesn't know why the system should be pressurised..or the effect that that has on the boiling point of water. .
Sorry I just give upon it
I ( shudders) leave you with tracey emen 's explanation of "art"..what I do is art cos I'm an artist I'm an artist ' cos whar I does is art
