Whew, channel cutting under way now...
My commercial slotting saw arbor just wasn't going to work, so I had to machine a new one out for 7/8 brass bar I had handy. I should have done this a LONG time ago, sooo much more solid now and runout on the sawblade is almost non-existent.
I'm also my own worst enemy..
I just wasn't happy with the layout on the 1/8" channels, I ended up going with a 1/16" slotting saw and tighter spacing so you more or less end up with 1/32" thickness fins and 1/16" channels. This should do much better thermally and flow good as well. Unfortunately this little change will make channel cutting take about 3x as long
It also took some creative clamping and layout, but I figured out a way to make a full channel cut in one past. Milling head is swung forward and the workpiece actually passes in front of the milling column...Whatever works, this is a big workpiece!!
Might be next weekend before the channel cuts are all done...
