      My only concern is the apparent lack of any swarf protection for the scale at the back of the table. I have a magnetic scale on my mill on the z axis and even there I have to be careful to prevent any swarf interfering with the scale. The glass scales, which I have on the X and Y axes, have much better built in protection. Although I really like the magnetic scale it looks much more vulnerable to swarf getting trapped between the reading head and magnetic strip.

        I've been using similar magnetic scales on my lathe cross slide and compound slide for a couple of years now and not had any issues with ingress of swarf. I have used a simple aluminium angle extrusion over each scale to deflect and swarf

          Thanks for your comments.

          I have added an aluminium anglepb291122.jpg/neoprene swarf & coolant to the rear of the table.

            Hi.

            I am now considering building a table power drive for the X direction using XL timing pulleys and belt driven by a stepper motor. Any suggestions on which size pulley's and motor to use would be appreciated.

            Thank you

              Power x feed.

              I did something similar on my Marlow mill, kept it simple and used a geared brushless 12v DC motor (Vexta) and speed controller I picked up the lot on fleabay for sub £50.00. Main problem was getting the belt drive system right to give a reasonable return speed but still be slow enough for some of the large end mills (40mm dia). Did not get it right the first time as it would not go slow enough so added an additional belt.

              More than enough power to move the table when taking large cuts with large end mills all be it aluminium with paraffin to keep the chips from sticking to the cutter.

              Used a simple dog clutch to disengage the drive when using manual "simples"

              At present all my kit is buried with a load of boxes in the attached garage of the house we have just moved to, waiting on planning to turn it into a garage/workshop 7m x 4.5 insulated with heating "Luxury"

                The only alteration to the mill was the relocation of the X axis feed screw press lubricator.

                  I really like this I've just got one of these mills from work (it was going to the skip bin!) I'd love to add the power feed. Is it economical or is it best to start with a newer mill?
