Afternoon all - I'm back on the last round of material testing. ALOX/epoxy, aluminium epoxy and another product. I made the moulds and top cauls today. I decided to make a caul vs just the bag to try to make a better shaped coupon. I can machine the AL to a true size but the ALOX, nope so the caul will keep it as flat as possible. Now to set up the mould parts. Peter
