What was today like? Not too much different from the
recent past...
Three more coating ready containers.
and, as you can imagine, the stock is increasing. Here are
the output from the last few days. I wish I could opt out for something else, something new! I will think about it!
There will be a BBQ, sometime in September, just postponed
from this weekend. One of my former colleagues is
currently on a business trip in the UK, and her suggestion
was just that! Incidentally, my wife and my daughter will
be in the UK, too, in February next year. I am not going!
Can't stand the long flight without smoking!
I will have to have a complete set by the September BBQ,
as there will be more than half a dozen former female
colleagues, to whom I have been giving away my artefacts.
My contact with the colleague, via e-mal, was made possible
by international roaming... Technologies!
Actually, the BBQ last October at my mountain cottage was
also organised by the same international roaming, amazing, is it not?
Here are some more and I will talk about these in some
details, using illustrations. One of the striking features
of my chopstics containers is that they are extremely
thin in walls. They are just like skins! Their structural
stiffness is therefore provided by the bottom backbones
of about 2mm thickness...
The following illustration is the key to it all.
This illustration is telling you how I go about making
holes and ellongated holes with my milling machine. The idea
itself is very simple.
Have the same sized (width, depth, and length) starting materials
and make peg holes down the centre and exactly equidistant
from their ends.
Easier said than done!
Now, A is the starting reference lines. They are only useful,
if drawn exactly from all of the sides that you use, with
the L angled jigs.
That is not easy, in the first place, what you need is the
equal lengths of the participating members. If they are not,
then they must be made eqaul, and once made equal, the pairing
must be preserved. That is why you see bellow.
I realise I am going back and forth, can't help it.
With the above the container cases are banged together with
the pegs, not seen, of course. Here, if the banged togerther
surfaces do not have discontinuities the rest is ever so easy.
In reality, there are discontinuities and they have to be erradicated.
And, if you do that the walls will inevitably get thinner
during the process of sanding away the discontinuities.
The discontinuities I am talking about can be best
illustrated by what follows.
B is the result of sanding out the discontinuities, the wedge
like indiscrepancies, and the net result is skin like walls
of the containers, which suits me very well...
With what follows, I will explain each element.
A is talking about initial reference lines, the exact positions
of which are critical to my operation, but, often, I cannot
guaratee ultra precisions...
B is showing you how cutting bits are hovering
above the reference lines and are about to be lowered
into the materials. This is where difficulties lie...
My bit, which is used for peg hole making is not
symmetrical, at all! The larger diamter trench
cutting bit is more reasonable, but with any of them
positioning of the bits is a demanding job, and that is
exactly where mismatching of holes and pegs sneaks in...
However, we are only talking about, at the maximum,
one half of a millimeter discrepancies, I think.
Walls being reduced by that kind of magnitude.
Is this a blessing in disguise? I do not know...
