Wayne,

My tool room buddy set the case up on precision blocks on the material of the main bearings, keeping things off the outside perimeter, and up high enough that the studs were off the table.

Then he used a dial indicator to locate the centers of the bores to get the block square on the x/y, then used the dial to get the coordinates of the broken studs.

This is when he handed it to me and walked me through spot facing the tops of the broken studs, center drilling, then progressivly used larger carbide tipped bits to drill up to 1/4".


I'm officially without studs now, pulled the last one out at lunch today. One thing I did learn was that a screw extractor is good for about 2 studs, throw it out afterword.

I don't know what EDMing a stud costs around here, but I got these done for a few hours of my time, $12 worth of screw extractors, and a case of beer for my buddy.

This weekends project is to clean the heck out of the case and measure everything, then make another order to Wayne's.
