I will certainly check them out if I end up needing more bits. However since I've reduced my depth of cut, I'm not going through bits anywheres near as fast. Between what I have now and the stuff I've got coming off E-bay, I should be able to get through these two blocks at least.

I'm getting close to done with the first block, I have all the channels about 3/8" deep at least, and have a quarter of them down as deep as I'm going to go. (I just hope I'm doing the math right so that I don't make a big hole when I cut the socket clearance step on the face of the block!) I'm leaving about 1/4" of copper on the base. According to the info Cathar and others have discussed here, should give good transmission to the pins and the rest of the block, without delaying the heat loss excessively.

It looks a bit ghetto, but I think it will work, and my next block should be a lot better...
