Thread: Brightening old tired metal

Hi John,

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.

This build blog warns against mixing imperial and metric dimensions, but also concludes that teh engine as drawn won't work:

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.

Awesome work Fizzy!

How long does it take to learn to weld to that standard?

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.

Wow - Fry's Powerflow is nasty stuff contains raw HCl

Telux is a bit less nasty, ZnCL and NH3Cl:

Thread: boiler reg h.s.e
16/07/2012 16:54:35

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?

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.

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.

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.

Thread: Dial graduations versus feedscrew lead.
21/05/2012 15:12:31

Kwil

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.

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

Ian,

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:

  • Straightforward paste, which allows for extended 'unicode' characters like euro symbols etc. as well as pasting across different fonts and the like.
  • Plain text paste (which reduces everything to just the basic 'ascii' character set - essentially what you have on the keyboard).
  • Word paste which intelligently removes the word format codes without getting rid of special characters.

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':

  • Plain text paste only (but this prevents the use of special characters & fonts)
  • Fixed width display, which forces links to wrap, but doesn't respond to things like changes in character size.

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
09/05/2012 10:03:27

Hi Bogs,

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"!
