[ELECTRON] Proposed new club + Arduino meet up

[Brian Loudon]

Hi Rep-rappers,

sorry I haven't responded before, yes I have 8mm smooth rod set aside in 
our workshop at work, I just didn't have time to cut the lengths at all 
as we had a big deadline today, and then I'm off on holiday for a week. 
I'm sure I can get hold of the plate too.

I never hobbed or hobbled or hob-nobbed a bolt before but I can give it 
a go in the workshop I'm sure. I'll be back around in a week or so,

cheers,
Brian
