[QUOTE="Rodney_gold, post: 78262, member: 579"] Will send you a PM , however you can't laser engrave Aluminium in terms of cutting into it - it acts as a sort of heat sink, a laser works by thermally shocking where it hits and vaporising material , the ally conducts the heat away too quickly , as you up power to try overcome this , you lose control. HOWEVER , a laser will leach any dyes out of anodising , the effect is a whitesih engraving and on silver anodised , its a very subtle effect. I won't charge anything for the 17 units involved barring postage. I await the CAD drawings and will come up with stuff for you. [/QUOTE]
