I can send you some 8mm SS threaded rod, think thats about £3 a lenth to me.

I also have some of these:


They are £7 each to you :)

The drive nuts would be £4 each, i will need to see how they turn out as i'v not done any with M10 holes, they should be ok but just to let you know. Just PM me if you would like to order the above :) and ill send you a paypal invoice ?
