Quill Scale on J-head Was: [BridgeportMill] M Head quill dro
开云体育
I made my own brackets to fit a scale on my J-head.? ?My brackets move the scale off to the right.? I still have access to the nuts to tram the head, to use the fine feed hand wheel and to be able to use the quick stop nut.? ? The only way I was able to package
a scale that satisfied all three requirements was to use a small form factor magnetic scale.? ?I started off trying to sketch my needed brackets - gave up rapidly.? I used very small scraps of wood, a band saw and a hot melt glue gun - took a couple of hours
to develop both bracket patterns.? Image attached (I hope) of the scale on my head.
NOTE:? ?I bought the 1u (micron resolution) scales - they were very finicky to get the magnetic gap so that the head would read consistently.? ?For my lathe I used the 5u scales and they have been rock solid.? ?I bought the Ditron / Reeson D80 DRO and scales.

I had actually acquired one years ago on a package deal ,but for a J-Head of course.?
Only for me to realize that I -DO- use the STOP that's there. And have a QUICK CLAMP for the one time use jobs.? The DRO bolts into that area , eliminating the screw and it's threaded stops. So I have never installed it , it's a Mitutoyo unit. I don't have an immediate recollection on what the M head uses there. |
