Hey guys,
Just bought a drill press and a xy-table to start my first waterblock. But than I realized how hard it was to cut the 1/2" copper slab I will use. I used a hack saw but it took forever and the result was terrible

.
I was wondering what you use to cut it in the size you want? I'm thinking in taking it to some kind of metalworking shop, but I would like to be able to do it by myself.
Any ideas? How do you guys do it?
Thanks.
