You guys have been very patient the whole week waiting for the epoxy to solidify. I think you deserve an update.
Here it is still sitting on the supports with some side boards removed. You can see the six steel feet sticking out. Four of them have holes for large locking pins that will locate the base onto the stand (which is yet to be built).
Removing the side boards was easy. I just took the screws out and yanked them off in one piece. The middle boards, top and bottom, are a very different story. They are squeezed between the sides of the base so removing them was a lot harder, but with hammers and chisels and pry bars they did come out with absolutely no damage to the part. Then the two rectangles were removed they same way, slowly but surely... Anyway, here is the final result!
The six pipes sticking out are the holes through which the column is going to be bolted to the base. The steel plate in the middle is where the Y-axis ball screw and motor are going to be mounted to.
The surface is pretty smooth but not entirely free of air pockets. However, I don't think that some air inclusions will be a problem. They may help dampen vibration even better!
The next step is to make a stand on which the mill will rest and lift the base up onto it before the grinding flat can begin.
