In my continuum quest for avoiding monotony, I left the cars aside for a while, and dedicated these last weeks to finish a model balance scale I had started some years ago...
I wasn't satisfied with its precision, trying different fulcrums, till I used some very tiny rolling ballbearings taken from a discarded PC fan...
Now it has a rather disturbing sensitivity, with much improved precision...
It's all polished brass throughout, the case being glass & wood.
The weights were fine tuned using a high precision digital scale...
Pics 1, 2 & 3 shows the scale with the case on....
Pics 4 & 5 shows the left & right fine tuning screws...
Picture 6 shows the indicator at dead center....
Picture 7 shows the rear fulcrum roller bearing...
Pics 8 & 9 shows the weights in their special drawer...
Picture 10 shows the scale doing its thing, here, weighging its own weights!...
