Congratulations Koi. My RF 30 has X oil holes, but not Y. It is easy to keep the Y ways oiled. Logically the Y is not traversed anywhere near as much as the X. I’ve often thought about making a simple cover for the front Y way but think maybe a couple of rubber way scrapers would be better, but then I’d need to install oil holes for sure. Ultimately keeping the swarf off them and keeping all the ways oiled with good way oil has been the easiest way forward. As far as tramming the head there are many good tutorials. Tramming the head on a mill drill can be very frustrating. And I would not trust using the cut from milling something clamped in a vise of unknown accuracy as a way to judge tram.
