The castings were hollow & required cores!
See my Pattern making Guide post #116, this thread
Post #120 shows some of our Patterns, Castings & where they were used.
3. 4 or 5 foundries around here, most grandfathered in, however no new ones!
Fann Blade: Looked at your Hurco retrofit thread – Keep up the good work!
A Lot of smart guys over there too….very helpful when you get in a bind!
I’ve retrofitted a Bridgeport Boss 4 and a 2J ……love the mighty Bridgeports!!
