Day 7: Accurate Weighing
Lovely, peaceful day
… pottering about in old sawmill.
from metal balance to a wooden one … it's so much better. It's so long
- the errors will be much smaller. I've been able to write the lengths
on it directly. And it doesn't bend with the weight of the 500g sugar
bag - so I can use reasonable distances from the pivot point - and still
get the bag balanced.
Don't think we need
to check it in Mike's sugar tube method … this will be so much more accurate.
It was good … woke about half hour before alarm went off. A fine time
of day to be creative. Mike was carted off to the river to help. I was
very happy finishing challenge off. With my new balance - I compared 500g
of sugar in some nails (yes … the nails I painstakingly counted yesterday).
So - I was able to work out exactly how much each nail should weigh (on
then I took 10 nails to find how long a piece of wire I needed to balance
against them. It was like a dream … 10 nails were 3850 mg … which needed
154 cm wire to balance, so 1 mg wire = 154 cm over 3850 and 10 mg wire
would be 1540 over 3850 - which is EXACTLY 0.4 cm. Seemed pure fluke that
it comes out so exact. But more possibly is a particular mass per just
length (ie, 2.5 g/m in this case!). Very excited
Nice way to finish
off day … feeling in control - and that a very good balance would be possible..
But I have completely surprised myself. I hate worrying about detailed
nonsense. Hate having to check, recheck, check again . I know you often
have to be as a security measure but I always make sure I look at areas
where attention to detail isn't necessary. It's NOT my strength. Give
me big picture any day (and EVERY day).
But - I have loved
doing this. I guess 3 days in a lifetime isn't too much commitment but
it's been a delight!
