Re: [mill_drill] cords of a circle & dividers
- Thanks Marv, simple and effective. Will do.owen-Owen,
I haven't done it in a while, but I would adjust the divider points
on a steel rule with engraved marks, and use the 1/64" scale. If you have
pretty good eyes, you can get within .015", and if you use a magnifying
glass, probably half of that. That's close enough for government work.
- If you do this sort of thing regularly enough and accuracy is
important why not fit a couple of suitable points to a vernier
caliper. The cost of digital ones has fallen so low in the uk now
that they are half the price they were a year ago. The usual exchange
rate for things that are available in the US and the UK is one dollar
to one pound, not the official exchange rate that the money markets
use. If that is the case then they will probably be available for
less than $25. If you have an old vernier you could use that for
dividers and treat yourself to a new digital one, they're far better
than struggling with a vernier scale.
