i have worked as a fleet equipment tech for 30 years and would advise not to sharpen these blades the sand we have here in florida eats the blades pretty bad,if you sharpen a worn blade you risk damage to the bearings in gearbox its called balance you grind off metal you change balance (take a blade off your ceiling fan and see what happens) why not change the blades its a lot cheaper than bearings and gearbox repairs and other peoples body parts

how about sand casting the gold
i have the DELFT CLAY kit and it works awesome look it up in google
i have poured gold pendents,rings etc.etc

awesome work great patina on copper

Thought I'd post some more pictures of some recent stuff.
This Thor's Hammer, bracelet and the previous Hesselbjerg amulet are all gifts for friends.
I'm having a lot of fun with this.
Hope you like them - I would love to hear what your thoughts are.
