My barograph nib now makes a broad line and/or smudges the paper, what can I do to get it working properly?
Barographs of the traditional type use a wet ink style nib. You should put a drop or two into the bucket of the nib and it should write reasonably thick even line. If it does not then you should check the following. Is the paper the correct type? it must be a special grade of paper that will not soak up the ink but will absorb a small amount of it. (Photo copies will not do) You should also have the correct ink for the paper and there are different types of recording inks. The pen should be in good condition, it may need cleaning carefully but if very old and corroded may need replacing. Our paper and ink work well together. We can not guarantee our ink on other paper or paper with our ink. It is normal to add a drop or two of ink every 2 or 3 weeks, if you are putting more than 2 drops a week in then something is probably not right! Nibs can be adjusted by altering the gap between the points carefully , they should be of even length and the wider apart they are the fatter the line is
