Hell, Id just like to be able to buy a drill press that can do 15,000 RPMs...
And would much rather have it fall over on me running, than to spill a crucibal full of molten Cu at +/- 2000 F on my leg.
I have a furnace that I made a few years back, .....I tried to make my own blocks when I first got into watercooling and it just didnt work out so well for my likings.Theres just too much work involved in setting up the molds for copper......... I just stick to Al casting for now if I find the need for it, which hasnt been too often, now that I own 2 cnc mills.

And for just so you know........copper is NOT "a bit hard to cast".........IT IS ONE OF THE HARDEST MATERIALS KNOWN TO MAN TO CAST . This is the main reason why it costs so much.
And its best cast in a controlled envirement, unless you like trillions of microscopic gas pockets all through your casting, upping the thermal gradient of the Cu...
You cant control that with your average backyard furnace...dumbas or not

All I can say is be careful......the minute you start thinking that you cant get severely burnt casting metal, will be when you find out that you can.

Whatever you decide on. Good luck
