Hi John,

Pleased the photos are of some help. Yes, you could possibly mount the Z scale a little nearer the column and save around 1" in its current orientation. It may also be possible to rotate the Z scale vertically clockwise by 90 deg avoiding the large bracket taking the movement to the slide. This would allow you to move the scale even nearer, but at the expense of more complicated fixing brackets. I try to mount the scales with the reading head facing away from the source of the swarf etc.

Not really for this thread, but I have had the Y nut come loose. I noticed this when the DRO Y display showed a different value to what the thimble was showing. When I strip the table to correct this I am hoping to fit a manual pumped oil feed system to all the slides. Lastly, I have also noticed that some R8 tooling has developed a burr on the keyway slot, so something may have damaged the locating pin in the spindle bore.

Regards

Ian

Hi John D

I have a green Myford VMC purchased in 1991. I fitted a 3-axis set of encoders supplied by Machine DRO/Allendale some 10 years ago. I believe these were the glass type as the magnetic encoders were not on the market at that time. It took a long time to fit and I enclose a few photos which I hope you find useful. As previously mentioned, if the X scale is mounted on the front face of the table, then you will lose the end stops and possibly the oil holes. If you fit it on the rear of the table you will lose Y travel.

I have also made a minor modification to the VMC On/Off switch mounting using spare brackets from the DRO mounting kit so the switch faces forwards.

The Sinho DRO display box I purchased has a problem where if you are using any of the special functions such as Pocket Milling, it will not function correctly unless all the measurements are entered in metric. This will hopefully have been addressed by the manufacturers over the years but it did fox me at first! Normal X, Y, Z DRO operation work well. It may be worth checking this before you get going.

Now with apologies for the orientation I include the photos. I have tried rotating these photos both in Windows and the tools in this web site with no luck!
