First -
Home is a basic, Edwardian 2-up, 2-down end-of terrace with a bit sticking out the back (the South Wing!) holding the kitchen and
en-suite bathroom. The front faces roughly North.
I have four wireless receivers, all ordinary a.m./f.m. transistor radios all on f.m., usually tuned to Radios Three or Four with occasional excursions down to Two.
They are No.1 in the kitchen, No.2 front room and No.3 back bedroom, the one I normally use. The No.4 is of course in the workshop, down the garden.
The problem is the variable quality of reception. Nos. 3 (a modern digitally-controlled radio /clock/alarm) and 4 are fine most of the time.
Now that I can t find the thread concerned!
Remember that strange circular calculator as we all thought it was, with the 16X table in the corner?
We ve sort of conditioned ourselves to think trades, particularly engineering but at least manufacturing (e.g. textiles or musical instruments).
Could it be that it had nothing to with such fields, but was used in something like Numerology - fortune-telling by numbers?
Why do I ask that?
I had had reason to verify a term I recalled from a weird pilot mathematics course at school - a
quincunx, for demonstrating either/or series in Probability. This little research showed me two things - firstly the term as I had remembered it is correct but used wrongly for that device (aka a Galton Board ) ; and secondly it is also used even more wrongly in astrology, numerology and the like.
Hi all people who own Chinese made semi-universal dividing head BS-0, BS-1, universal dividing head BS-2.
When I used the dividing head, I discovered that there were hard points in the bearing, the crank did not feel the same all the way. Then I noticed that the workpiece that was milled was not in the center since I use an adapter with ER-32 collet attached in dividing head.
So I measured with the dial on the cone inside the dividing head and discovered that it was a throw. Tried to adjust the thrust bearing without it helping, still slack in the spindle.
I thought members may be interested in my completed excavator arm, something I have wanted to build since being a small boy.
I have scaled it from a die cast Kubota model I have and it was never my intention to make a replica model, just somethig that looked OK and I could play with. At the moment I am running it at a 100 psi at which it seems to have more than enough force. During some early experiments I used up to 150 psi and apart from a few tubes blowing off it held together.
My main concern was that the 4mm tubes used would be so restrictive as to make the speed of operation too slow but it is OK and to scale .
