microchannels ..VIDEO: http://www.youtube.com/watch?v=As-LZAdpPeo

This was Naekuh's TEC block in the works...it took forever...twice!...lol!


No pain..no gain..

Serously though, I don't see why you couldn't, especially if you made an arbor that was keyed for these types of saws and oversided in outer diameter to support the blade with the same oversized spacers.



That video looks cool on cnc, but try it by manually milling at much lower RPMs. Cutting one block like an EK supreme will take you all day just to cut the base and that's assuming you don't screw up one of the steps and have to start all over again.

If I had plans to make more than one, I'd sure try it. It's not all that different than running a dado set on your table saw and I've done that plenty. On the mill, I consider some of the larger endmills and facing mills much scarier to run than a slitting saw. While I have had those grab/walk/ruin a work piece, I've never really had much incident with the slitting saws. My biggest problem was getting them to run true on a low cost arbor....in the end I made my own. It worked pretty well other than being extremely slow, although I'd probably do it differently now that I tried it once. I think you want the arbor to be even larger in diameter leaving just enough saw blade to make the necessary cut depth...this would go along way in preventing flex/vibration.

Just makes me wonder what some of the current mass production manufacturers are doing. I'd bet some of them have some sort of gang setup...but they never share the juicy efficiency bits with us garage builders..

There has got to be a better way to cut microchannels. Horizontal mill would be ideal, but what's the next best thing without a horizontal mill or CNC?
