The only places that require a 1/16 bit are the o ring grooves on the base and middle pieces. Everything else ended up with 1/8 radius.
I machined the radius with a ball end mill, which is time consuming, but less than doing it by hand. The base this fits in was machined using a ball end, so to fit I have to radius the bottom. Here is what mine <http://aercon.net/Public/Image40.jpg> looks like.
