First thing in the morning of today I took my wife to
Kamakura for her regular gathering with her friends.
Some progress was also made today. Progresses and
improvements are incremental, though, simply because
you have to, from time to time, take a step back and
put the whole thing into a perspective. Today, probably,
was one of those times. Take a look at the following.
What I am trying to do here is that I want to make
holes with precision. I talked about the precision
in making holes and how that can affect the whole thing.
You are looking at my milling machine, with the precision of
0.2 mm, that is to say, I can move my dril bit that precisely.
In reality, you do not need that sort of precision.
The end result is shown in the following image. Because holes
were made at the right positions the lids can be
banged together without protrusions whatsoever!
This makes my life a lot easier, indeed.
At the end of the day, I want very smooth surfaces,
all around, for eventual commercial purposes. Now,
take a look at the next photo.
The edges have been rounded nicely. You can see a cut at one end.
This incision is for you to open up the lids easily with your
finger nail.
The next photo is the comparison.
By far the most important thing to remember here is that
with all of these containers only one, a 12 mm diam. reutor
bit has been used. See these incredible differences?
The second one from the bottom is today's, third one from
yesterday, one at the bottom was fabricated, a week or so ago.
Now, one at the very top is out of the question for
actual use. My current thinking is this. One at the very bottom
has my 190 mm chopstics OK, but they are placed inside
the container anti-paralell. On the other hand one above it,
that is today's can easily contain my chopstics paralell.
Remember all of these have been fabricated using various
line drawing jigs, which I showed you yesterday.
Still a little wider than my liking, today's might be OK,
because one of these days I will be using my new 8 mm
reutor bit, instead of today's 12 mm bit.
That should shrink the overall dimensions to an acceptable
level. That brings me to my next topic. See bellow?
This is really about actual placement of my chopstics in
the trenches. I only use round headed bits, so that cleaning
the trenches becomes easy, compared with flat bottoms.
Now, if you use a very thin round headed bit, its overall
effects are the same as with flat headed bits. In A, I
am showing you such a thin bit in red.
It is swept across as shown by the arrow and that leaves
almost rectangular bottom corners at either end, and
you do not want that!
B is showing you my operation with a larger diam. bit,
and as indicated by the arrow, you have a round bottom
corner. This may seem nice and tidy for cleaning purposes.
However, it does mean that the thickest part of my chopstics
can be fully contained.
This is depicted as C in my illusration, exagerrated.
If, however, I get my 8 mm bit, and I am craning my neck for that!,
the problem might be less serious. Let us see...
My point is that the tip of my thingy may well sit halfway
down the round corner, as shown in C!
This, above?
It was my experiment, and the photo is not very clear.
I was trying extremes, trying to immitate the one
at the bottom of four containers you saw at the top
of this page. I failed, and lost any further interest and
went out cycling to a nearby island...
As I continued trench forming the side walls of the trench
got thinner and thinner (as expected as the bit went
further down). There was a real danger of my bit blade
interfereing with the vice grips, damaging the bit, or,
even worse, damaging the internal electronic circuit
of the milling machine.
Conchita, I will be sending you my infant spoon within
the next few days, along with other cutleries for your family.
Take care!
