I have just found a good supplier of cheap metals in Europe that does cheap international delivery. Just placed an order for 1/2 kg of silicon. Half the price of anything I found on ebay. Will let you all know how it turns out. https://auremo.net/2-home
Couple of places that I buy my supplies from: https://www.artisanfoundry.co.uk/ https://www.sdtsengineering.co.uk/shop/
