Can I pick your brains please.
What are the standard diameters for wooden dowelling. I don't want the
downright specialist sizes please because I hope to find it at one of
my local DIY superstores!
My application is to use a very short length of dowell to replace an
AAA or AA battery in order to run an electrical device all day. The
dowell would have a drawing pin at each end with a thin wire attached
which is connected to a 1.5volt power supply at the other end. IYSWIM!
The cell diameters are as follows:
AAA cell = 10.5mm (0.42") diameter
AA cell = 14.5mm (0.58") diameter
What alternative material to wood could I use?
