If you decide to gear down your steppers, the torque multiplication effect will give you more cutting force at the expense of rapid speed. The first job was to find replacements for the handwheels. Light cuts just cause the Bakelite to melt and harden, and blunt the tool even faster.

For the gory detail of my attempts to build an Arduino-based reader see this page. The kit contained the multi-function display, and three linear scales. Early heads were very reliable, with reports of them being in continuous service for over 25 years, Unfortunately, heads made after approximately were fitted with “improved” plastic gears in place of the earlier fibre type and theses can suffer from loose bushes that allow them to slip down and partially engage the face dogs of those beneath, so locking the drive.
This two-part design made it easy to align everything and mark out the screw holes.

While not ideal, I think that even if this rust had been on the ways it would not have caused too many problems. If these screws are mishandled the block will be cracked – therefore any adjustment should be approached with caution. hobbymatt
To figure force you can use the equation given by figure 11 at the Nook site here: Ball Screws, Ball Screw Glossary This equation will give you the linear force applied for the load you will have on the table.
I have been using the DRO almost daily for a year and a half, and wonder how I ever managed without them. In the end I rubbed it down gently with some oil and fine emery paper, and left it at that. Looking to make small parts from Steel and Aluminium such as brake calliper mounting brackets, milling the faces of small steel plates up to xx10mm perfectly flat both sides and squaring up the sides, drilling up to 20mm thick plate, tapping holes, cutting slots and recesses into parts etc.
The display head comes with a number of functions. You must log in or sign up to reply here. I would get one good pass with a heavy cut, then remove the tool for sharpening….
