Krusty, how did you get it all to come out even? The
idea to increase the spanning distance with a shim works
because the metal in hard. With JBWeld all you get is
goo, right?
It took a couple tries to get it down perfectly. I used a method someone else posted on the forums.
First, find yourself a nice smooth piece of glass, some WD-40, and some JB weld. Mix up a little JB weld and let it sit for several hours. IT takes like 5 hours to harden, so I waited until it was more of the texture of play-doh to start using it. I knew it was ready when I could scrape a trough in it and it wouldn't smooth out after several minutes.
I scraped off the feet and cleaned the surface of the cpu. I took 4 little balls of the JB weld, stuck them in the place of the feet and pressed on them just lightly enough to get them to start to stick on the cpu.
I then put a thin coat of wd-40 on the glass and placed the cpu face down on it and moved the cpu around a bit to keep the JB weld from sticking to the glass. This took a couple of tries because I started out just pressing down on it and the JB weld would stick to the glass no matter how much WD-40 I put on it. I applied enough pressure on the glass and cpu to be able to see clearly that the die of the cpu is also pressed closely against the glass. Just to be safe, I stayed in front of this for a little over an hour making sure the jb weld wouldn't stick to the glass and keeping it face down to prevent gravity from deforming the jb weld at all.
I then plucked the cpu off the glass, let it harden overnight, and cleaned off the wd-40 that was all over the cpu.
For the test to make sure you didn't make the feet too big, place a piece of paper on a piece of glass, press the cpu lightly on a stamp ink pad, and use teh cpu to make a stamp on the glass. If you can't see the whole die on there, it's time to scrape off the jb weld and try again.
