Certainly a block thick enough to keep the lowest point of the main casting clear of the table. Then a couple of "wings" for hold-down bolts to clamp it to the mill table. You need to decide whether you use 2 or 4 bolts. And think about access to the nuts or bolt heads. Then, because radiuses and fillets are "free" with printing and casting, you might as well add those. Maybe your own logo :-) Add extra metal where machining will be needed, and allow for shrinkage. > The only "true" surfaces on the back are the dovetails. > I think that's a bit of a wimpy mount. It was considered adequate in the original design. I think it would be fine. You could consider making the dovetail far longer, as you probably don't need the traverse ability. (But then you would have to make a new Gib rather than re-use the existing one) Measuring the dovetail angle is important, I have seen 60, 45 and 55 degree dovetails on machines that I have owned. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
