RE: [CAD_CAM_EDM_DRO]Backlash & Wobbly Spindle on my Bridgeport

Wow you can sharpen a drill that is .012" diamenter? Man my eye sight ain't
that good.

If you cannot find a center drill small enough I like to take a regualr
jobber length drill and cut it off so only maybe a trun or two of the flute
is left, then resharpen. This way when you chuck it in your drill chuck at
most a quarter inch is sticking out. Makes for a lsightly stiffer drill than
a full length and gives you the size you need instead of huting for a center
drill that is to big anyway, but I do believe I have a few center drills
that the starting section is under .110, would have to go measure to be
sure.
