Description
Product Overview
Proper machine leveling is the foundational requirement for any precision machine shop. If your lathe bedways have a twist or your mill is out of tram with gravity, chasing tight tolerances is an exercise in futility. The Riken Keisokuki (RSK) 250mm Precision Machinist Level is a professional-grade Japanese layout tool designed specifically to establish and verify absolute levelness during machine tool installation, rebuilding, and routine maintenance.
- 250mm Bedway Footprint: At 250mm (approx. 10 inches) in length, this is a substantial, heavy-duty level. It provides an excellent, long reference span, making it the ideal size for bridging wide lathe ways, setting up large surface grinders, and verifying expansive milling machine tables.
- Highly Sensitive Main Vial: The primary glass vial is engineered for extreme sensitivity, allowing you to detect microscopic deviations in your machine’s geometry. The vial housing is fully adjustable, allowing you to calibrate the bubble to absolute zero to maintain the tool’s accuracy over a lifetime of use.
- Precision Machined Base: The underside of the level is precision machined to strict Japanese industrial tolerances. It provides a flawless, flat mating surface that ensures the bubble reading is a true reflection of your machine’s alignment, eliminating false high spots or rocking.
Condition
Used (Good Condition / In Wooden Box).
This precision level is in good, fully functional used condition and has clearly been respected in a professional shop environment.
- Surface Condition: The critical machined bottom is completely smooth to the touch and entirely free of rust, dings, burrs, or physical damage. It does show some cosmetic discoloration and visual patina from age and normal shop use, but this is strictly aesthetic and does not compromise its seating or accuracy in any way.
- Complete Setup: It comes safely housed in its original wooden storage box, providing crucial protection for the delicate glass vial from shop floor accidents and dust.
