This is the traditional Newing Hall base unit. The flatbed engraver sits on top of the base,which also utilises the cylindrical attachment. This is raised and lowered on a lage diameter rod. The photo below clearly shows how the two central pillars move together on a machined slide. The clearance is taken up by grub screws acting on shims. Over time, these components do wear allowing excessive movement. Though when the threaded screw is tightened to grip the cylindrical object, this is movement is taken up. I recomend stripping this assembly down yearly for a good clean and grease round, re-adjust the shims as required. After 6 or 7 years of daily use, cosider replacing the threaded rod & brass nuts.

The Kirba base unit is shown right. The machine is currently set up for cylindrical engraving. Obviously either a TLC or Apex controller can be used, the flatbed unit being the same. The two upright pillars can be adjusted along the central spar. The clamping method are the two black knurled knobs at the front.

This is a close up of the vice assembly holding the long central spar. The two small levers either side of this spar clamp it in position, whilst the handle at the front tilts the entire mechanism. The large orange handle at the front moves the assembly up and down. The black knobs either side lock this mechanism. This is a substantial unit which provides a solid base on which to mount the item to be engraved
