Thank you all, David I am a member joined in March I think last year, after watching Ron Dodd on you tube & yes I bought a magnetiser too, very happy with that.
Those springs are still available great I’ll have a look through them Ray, I’ve seen a few in the bag for other uses:-)
Il Grifone, I like that idea, you could probably get a couple or three from one spring & I’ve a few odd looking ones in the box! Excellent I’ll keep you posted thank you again
