You will lose a little through evaporation. Quick test - if you can smell it, then there is some present in the evaporating water - the stronger the smell the more acid that is present in the vapour. However the human nose is quite sensitive and it takes relatively few molecules for the brain to register its presence. In this instance the bulk of the acid will slowly concentrate in the reducing water volume. Pero

The quality of work from a machine is dependant on the skill of the operator. I know of a mini lathe ruined by a careless, to be charitable, operator. Repairs are likely to cost almost as much as a new machine! Yet there are lots of folk doing fantastic work on them. (Most mini lathes come from a very few factories in China ) So the difference, in many cases is not the machine but the operator. A skilled operator can produce good work on a mediocre / worn machine. Think of the work that was ma...

I bought a DB10 in September and so far its doing everything I want. It was as big as I had room for, and it more or less was within budget. Low speed torque could be better, but for the money it certainally does the job. Up to now Ive done a little fettling, fitted an AXA QCTP, and a DRO. The QCTP needed a bit of work to make it fit, but its transformed things speed and convenience wise. I also purchased the DRO from Chester (too lazy here to try to work out what I actually needed!) was a litt...

Just curious, not really sure if I want to spend too much time on a VGA gadget, but I have a vga screen that has been kicking round the shop for too long. Hi Roger, The VGA graphics are generated by the underlying hardware but much of the programable functionality is built into the BASIC engine. The CMM2 is built around a single Waveshare MCU chip, which uses a Corte...
