Had some free time at work so snuck in a little home project. Used a rotary saw from Harbor Freight. I got a couple of A7 attys, top and bottom feeders. The BF cap looks like the ERA and has no holes in it. juice and air are supposed to come from connector. Here is the saw and cap clamped up.
Used a drill press with 2 axis vise.
