|Thread: Pansy Valve Gear|
Yet another plea, as Bruno's above !
Anticipating a major rebuild of the valve gear, can we see these mods of Julian Atkins please?
|Thread: Laser cut plates|
34046 - Have you checked with Malcolm what excess - if any - he requires to be added to your required dimensions? He's done several laser-cut items from my CAD dwgs and he's queried some of my dimensions thankfully !
The laser-cut edges from the company he used for my items were "rough" and hard. They needed draw filing smooth with a diamond file, I accept that techniques may have moved on in the last couple of years but a small dimensional excess was incorporated to allow for the smoothing-off.
|Thread: Another scam|
'would recommend a look at the website "Who called me?"
And always worth adding the scammer's number to the website.
|Thread: Metal Bandsaw - Chester H80 or Warco CY90|
" no one seems to do powered hacksaws now - that I can find anyway. "
Like "Plasma", I favour a powered hacksaw.
" Did I once read somewhere that metallic mercury was used as a treatment for syphilis? Blue Pill? "
Indeed - it was the only treatment from the middle ages, until Salvarsan was discovered in the early 1900s.
Really getting off-topic now
" wash with a soap containing mercury, it seemed like a good idea "
Clive ~ we used to just squeeze the mercury through a new chamois leather to clean it. I would doubt it'd be cleaned with nitric acid, even if dilute it would form mercuric and mercurous nitrate salts.
In terms of huge volumes of Hg, the Castner-Kelner process for producing chlorine and caustic soda by the electrolysis of brine is worth a mention. The old ICI "cell rooms" in Cheshire were incredible; in each, the amount of Hg could be around 100 tons, the current required upto 200,000 amps at 200V. The gap between the electrodes and the Hg surface was very critical for efficiency - too close and imagine the result !
But back to reminiscences of school days in the chemistry lab., as others have mentioned the inevitable little globules of Hg would collect in the benchtop grooves. At my school we were required to use only fountain pens for note taking. The rotten trick was to take someone's pen, with its gold nib when they were not looking and press the nib in to the Hg. The resulting amalgam would to cause the nib to disintegrate and the pen's owner distress.
|Thread: Motorcycle 'blipping'...|
Not with modern bikes I suppose but with my old Brit bike, when stopped and ticking over you had to blip the throttle once after pulling the clutch lever to free the clutch plates in order to engage 1st.
Irrelevant addition follows:-
|Thread: Practical Electrical Engineer|
Maybe drifting a bit off topic, but the complete collection of the Meccano Magazine is available on-line.
For anyone unfamiliar with the old magazine, it is not exclusively about Meccano, but contains fascinating articles covering all aspects of engineering.
|Thread: What do YOU call it?|
|Thread: Nickel Plating Brass|
Nice job Russell, looks magnificent ! I kept my steel plated m/cycle bits well waxed. The bike was only taken out in good weather so didn't experience your " it is not weather resistant unless you plate with copper first."
The topic was discussed on here before - just over a year ago.
Forgive the repeat, but to anyone "contemplating plating" at home, this was my posting then (truncated):-
(Edit for typo)

My understanding is that if Cu and Zn are present in either the electrolyte or anode they will also get deposited on the item to be Ni plated.
The book cited by Russell is an interesting & comprehensive read. Therein the only statements relevant to anode purity I found on a quick scan were:-
Not so sure I'd want to risk Ni plated stuff.
|Thread: Soft Solder v Silver Solder|
"......... - how do I calculate my exposure and associated risk ? "
VERY unreliably ! There are too many unknowns with respect to your actual exposure and translating that to the more important index of dose received. (dose received and exposure are not the same).
|Thread: Tail stock adjustment|
Pat, how did you measure with the dtiI that the tailstock was higher?
|Thread: Bore micrometer|
Adam, I don't disagree in principle about holding two of the axes steady but I didn't do so for 2 reasons.
For reasons to do with the special piston rings that were to be used, the bore had to be 1.500 + or - 0.001" throughout the length. I was using a between centres boring bar and that had to keep being removed & replaced for the DBG as the required ID got closer - a PITA.
'had written before" take maximum reading as it's moved around".
This was it in use:-
Valuable comments above ! Kiwi Bloke ! makes observations I can endorse from experience.
I suppose, given my ignorance in such matters, that the least subjective method might be to turn down a diameter of steel on the lathe until it "just" fits and then measure its OD with a micrometer (allowing for temp equilibration). But that's fraught with problems of surface fnish etc and gives no indication of bore ovality.
|Thread: Setting Milling-machine Vice|
The subject has of course been covered before here in May of last year.
On 30/05/2018, I posted "Lining up the milling vice....I'm with Clive F's 4th para "Personally I'm not great lover of keyed vices.... etc"
Further details & Images shown with that original posting.
I still find it takes about one minute that way and is always accurate.
Edit:- Apologies - I tried inserting link to that thread but am getting error.
Copy & paste that into search bar should bring up Google link
