And the winner is .......NB70 - tks matey.....I've seen that site before -....great value stuff on there (just got to work out what else I'll never use to bump my order up!)

5mm x 19.8mm @45p for 10 pcs - both ends useable so after parting off to the right size that's in essence that 39p for 20! (which equate to about 2p per pole pice - far more digestable vs 40p per pol & might even mean I can make some early prototypes for a decent price!).


Peter - a wonderful idea about using a hacksaw blade...I'll see what google turn ups...but how are they normally held?
Many thanks to all who chimed in here - some great ideas & comments - you're a great big font of helpful engineering knowledge & willing to help 'wet behind the ears' types like me!
