Well, all g.l.amour said about making the blocks for the money, same here. I'm very glad you (#Rotor) helped us, I give it very much appreciation. This was, is and will be done for fun and improved cooling, and in my case, for gift to some people (two of them actually). Thanks a lot, again.
g.l.: hehe, I just did the vacuum cleaning today, and did it good to pick all the copper flakes from my carpet (brought them from the balcony on my slippers)
. Now is time to clean up the balcony, just after I take some pic's (regular, not digicam) for showing other people how good my wife is, and what she can stand in her apartment
.
Now, I got some more questions for ya!
How the hell did you manage to spend only 1/5 of the disc for whole half of the block?!?!?!?
I use Minicraft brand (only ones available here), and they don't last long. I cutted also with approx. half the max speed of dremel.
Also, what's the distance between the holes in block (rim to rim of hole)? I managed to drill with 4 mm bit with 0.5 mm distance between the rims of the holes.
I certainly have more of them, but just now, I cannot remember any.
Keep it fun!!!
