Hi Jerry,

       I use the P250DH size 1" x 1/2" x 1/4" which is more than adequate 
with a 1 kg mass.

       What mass are you using?  

       You will find that Alnico U magnets are quite expensive as well as 
having a much lower field.

       Yes, I am in the UK. I have a Metals Supermarket about 5 m away!    

       www.ksmetals.com stock 1/16" Al and 1/32" Cu. Model shops carry their 
products. They are not cheap, but you don't need much
       Can you use your phone directory to look for non ferrous metal 
stockists? How about Home Depot and similar places which sell hardware / plumbing / 
building supplies? They stock the bright mild steel strip and zinc plated mild 
steel set screws.
       You do have a huge online hardware supplier, but I can't remember the 
name. Steve Hammond might remember? Sean Morrissey used them a lot. I think 
that it began with M? Sorry, but my other computer is 'down'. Check

       Regards,
