    trying to find best compasses/dividers

    Hello everyone

    I could not find any post asking for advice on maths equipment so I could be in totally the wrong place - apologies in advance for that. Here is my question, in case I am in the right place ....

    My son has bought at least 4 pairs of compasses but he says they always move whilst he is trying to draw his angle. He might not be the most dextrous of children but there must be a 'best' pair of compasses or dividers out there. He has a very important exam coming up and I'd really like to get him something that won't add to the stress of the situation.

    I'd be very grateful for any recommendation(s) and/or advice.

    I have a fine pair of compasses that I inherited from my grandfather, who was an engineer. They must be well over 100 years old, but I have the same trouble with them that your son has with his. This is obviously a long-standing problem that makers of compasses have failed to crack. The only advice I can give is to stick the point of the compasses very firmly into the paper, and then trace the circle slowly, in stages, without applying much pressure. It may be necessary to go over the circle more than once to make it clearly visible.

    Sorry I can't be of any more assistance with the problem!

    Many thanks OPALG for replying.
    At least I know now that I could be wasting my time looking for something that will not move. I will pass on your advice about how to use them to my son.
