I need to mill some 3/8 angle Iron flat on the back sides and at least one of the insides of the bend. the angels is 4" x 4" and 24" long. The outsides needs to be square or perpendicular to each other. the inside part should be parallel to the outside machined surface.
I was think of clamping the angle upside down to two angle blocks on the milling table and indicating it in, but the surface is really rough and rusty.
i suppose I can try to get it close and take a shallow cut first then indicate the newly cut surface and re-cut, and then flip the cut surface against the angle plates and star the other side. Another idea I had was to clean up as much rust as i can with an angle grinder and abrasive pad. Then clamp that part to the table, and then mill just the 3/8 edge and then flip that 3/8 edge over and rest it on the table when I clamp to the angle plates, this will at last get me close to fat to table.
I have not had to do anything like this on the scale so any incite will help.
