A couple of years ago I had left the machine light to close to the quill DRO on my mill when I went to lunch.
I now turn everything off when not in use.After lunch i?returned?to find it had??melted the some of the push buttons.
I was?devastated,immediately rang??Hugh of Amadeal and he just so happened to have a spare DRO and shipped one out.
I might add at a very reasonable price and delivery as normal.again many thanks Hugh.
My motto Don't throw anything away,and turn off everything when not in use.
The old DRO sat in my drawer for over a year and I decided to try repair it one day.
I used a scalpel and carefully cut the melted areas around the buttons,dis-assembled the unit it and got it to work.
but not all the buttons, the on/off ,metric/inch after some carefull surgery worked.that's all I wanted.
Not really keen on the graduated dial and depth markings on the tailstock,I
decided to use the old DRO and attach it to the
tailstock with a knocked up bracket and clamp I had from some scrap pieces.
You will note that the bottom half of the DRO has tape around,that covers the battery cap that was totally melted.
If I need to change batteries,I just undo the tape and swap them over,and re-tape. Also keeps any chips from?
going inside it.The DRO works fine now.
You will also note from the photo's on the top of the tailstock and extra brass thumbscrew.
I had some rotational play from the original quill locator pin and slot.
So machined into the original quill square slot
a new groove with a 4 mm ball end mill,just slightly deeper than 2 mm and
sitting under the thumbscrew is a 4 mm ball bearing.re tapping the original thread to 5 mm using a 4.2 mm tapping drill and made a new thumbscrew.
The sideways motion has now gone away.

Last photo is of the replacement DRO in its operating pocket on the mill.
Hope this was of interest.Don't throw anything away,but I need a larger playroom,just had one built,still not big enough.
