measuring play in quill+spindle of milling machines & drills
I'm hoping that some here have measured the play in the quill+spindle
of bridgeport & equivilent millers, which will be a deciding factor when I
buy one in the future.
The measurements that I have made were by chucking a 10 inch piece of
bar stock and pulling 10 lbs left then 10 lbs right at the end with a spring
scale with the quill lock, when present, loose. A dial indicater set on the
spindle indicates the play.
A small bench size drill press, a $60 version, showed 13 thousandths
of an inch play, 8 for a full size and heavier drill press, and 5 for a
spanking new mill/drill from Harbor Freight. The last omitted the scale
which leaves it a bit questionable.
If anyone has made equivilent measurements, posting the results
here would be greatly appreciated.
