Superb....... I was looking at it as a mill made block until I got the where you showed the pillar drill. realty excellent and it shows just what you can do with limited tooling and a little bit of true ingenuity
I made my early ram blocks with a pillar drill and an old lathe as X-Y but is was not up to any sideways milling at all, so joined holes a-la-rotor was the order of the day.
I know its' the way you had to do it, but the only thing that makes it look a little home made is the blue sealant IMO. What you could do is take the clear tops and get a machine shop with CNC to mill you an thin o-ring grove, (should be pretty cheap), then get the appropriate size o-ring...... spend an evening with t-cut & polish on the copper parts and they would look better than production quality, (it is easy honestly)
........don't forget some pics of the cooler on the card later on btw,
A really super job, and I'll have to watch out if you get a mill
