|Thread: Brightening old tired metal|
Here in the mother country we moved on from scouring powder in the '70s.
I still have nightmares about 'skates on ice' as this video demonstrates:
We now call Jif Cif, for some unfathomable reason, Ajax is long, long gone.
|Thread: Stan Bray's Slim Sam|
This build blog warns against mixing imperial and metric dimensions, but also concludes that teh engine as drawn won't work:
|Thread: Tools explained|
Obviously inspired them to dreate the 'real' product:
Presumably it's like Bradex Easy Start - ether and various other nice-smelling things in an aerosol.

Great article Ramon,
|Thread: New Steel Boiler for under £200|
Awesome work Fizzy!
How long does it take to learn to weld to that standard?
|Thread: 12 Volt PMDC motor armature|
Take care Michael,
This is the sort of thing that can happen if you are careless about speed control on mobility equipment. A sober warning for us all.
|Thread: Will electrical 'multicore 'solder adhere to brass ?|
Wow - Fry's Powerflow is nasty stuff contains raw HCl
Telux is a bit less nasty, ZnCL and NH3Cl:
|Thread: Warco Super - Major Vario inaccuracy|
Spellun Crap All Times
|Thread: boiler reg h.s.e|
I see from the Walker Midgely site that boilers of less than 3 bar-litres capacity don't need a test certificate **LINK**. I estimate the capacity of the large Tich boiler as about 450cc, and the pressure is no more than 90psi (max, so that's roughy 0.450 x 4 = 1.8 bar litres.
Froma purely legal insurance perspective, not individual club requirements, is it therefore correct that a Tich boiler would not need a test certificate?
|Thread: Barrett Exall and Andrews Engine|
Is it the same Tony Webster who made the gold-medla winning International Harvester Titan tractor? There appear to have been a few errors and ambiguities in the drawings for that back in the 90s.
We have to accept that the best modelling skills don't always mean the same level of draughting skills.
|Thread: Parallel Motion|
I have never understood why it took so long for the crosshead guide to be invented - it seems so obvious and makes the whole construction of an engine so mucjh simpler. Presumably it is because of the evolutionary progress from atmospheric engines, but it is ironic that, aside from the valve gear, later engines were much simpler than earlier ones.
Another example is the time taken to use horizontal cylinders, although with the poor facilities for making truly circular cylinders in the very early days they would have struggled.
|Thread: Steam engine timing|
And if you really want to get into it, check out this:
I agree the the point made earlier that 90 degrees is not a good setting for eccentrics, and most need a lot more than 10 degrees or so of advance.
This might be helpful:
|Thread: Dial graduations versus feedscrew lead.|
My machine (seig version) has 75 graduations of 0.02mm and 1.5mm of feed per turn of the handwheel and is clearly marked as such.
Are you assuming that the 75 graduations are 0-.01mm each?
60 graduations would be a much better choice for both metric and imperial work.
|Thread: soba centre square|
More likely hobby exhibitions are a brilliant opportunity to shift returns that you wouldn't sell over the counter or by post.
|Thread: Rotary encoder for spindle speed|
Cheap sensors for opto-encoders in old computer mice.
|Thread: This website is working very slow today, Anyone else having problems?|
Very slow last couple of days.
Suddenl;y fast again today.
|Thread: Not fit for purpose|
One has to laugh. But perhaps someone should gently inform Eric that model engineering is a hobby and yes, the drawings are almost entirely drawn by amateurs
|Thread: Text and Adverts|
The problem is that a copy from word includes a whole load of control characters. These are not interpreted correctly by browsers that expect HTML tags instead. As it's impossible for an editor to know if the text is from word or not the user has to show what they are pasting. Hence there are three past icons on these edit boxes:
So, there are choices facing the designer of a facility like this - they could include any or all of these three options. The only way to be 100% safe is the plain text mode, but the people would be complaining when any special characters disappear.
Similar issues apply to hyperlinks, which is why a special button is provided that should make links unbreakable and allow them to wrap properly. If this is not used, the form 'thinks' the link is one very long word, and doesn't wrap it.
These issues face all webform designers, and ultimately are down to the limitations of HTML.
In due course there will be better solutions but most of the websites that appear to be problem free do two 'cheats':
We shoudl appreciate that they have invested in proper editor, apparently the same one we use for our CMS at work, and though it takes a little learning, anyone who can operate a lathe ought to be able to grasp the basics in a few minutes.
|Thread: 5mm Pitch Roller Chain|
the smallest pitch on teh RS website is 6.35mm - suspiciously close to 1/4"
Smaller chains are out there. But if you search google for 'chain' it includes results for 'belt'!
So try a google search for: 5mm pitch chain -belt (note that minus sign before belt)
This is on the first page:
Unfortunately that's "price on application"!
