DC-40 power feeder comes with 1/2" bolts for mounting base plate to machine. Felder F900z drilled and tapped from factory (nice) for 10mm bolts (ugh). Very big difference in mass in those two. Naturally, the internal debate goes like this: Is CoMatic is over-killing with this size, or is Felder over-confident in the smaller 10mm bolt?
While I don't really feel like re-drilling and tapping for the 1/2", I certainly am not thrilled about the 10mm bolt slopping around in the 1/2" holes in the casting. Thought of tapered seat, but that could lead to strain/cracking of the casting, so perhaps a bushing, if I stick with 10mm...
So off to the hardware store I go for 1/2-13 tap or 10mm bolts.
What would you buy in this situation?
