Front lock stage
Some of the problems with ordinary miniature stages are that they tend to have a lot of play in their movement, and the spring types tend to creak.
However, Miruc’s front lock stage, though miniature in size, has no play in its movement and is able to deliver an extremely smooth sliding action. Also, the base of the handle has a locking stopper function as standard, affording superb operability.

The product which poor in precision, you may feel a strangeness in operation of full stroke with sliding the stage from the side by side. The feeling of operation depends on individuals.
■Grind
“Strange feeling, vigorously scraching something when turning the handle.No smoothness.
Many cases occur when tightend harder together between the rack and pinion.”
■Uneveness
For all strokes gets heavier or lighter for uneveness.
Many cases occur when weak tightening between the rack and pinion.
■Gap
Sliding the stage to one side makes the feeling as if the satages are scratched and becomes heavy.
When sliding it on the opposite side makes it feels lighter.
■Backlash
The play between male/female dovetail groove parts.
■Play
The gap between the contact face of gear that is intended to be provided in the direction of movement. By suppressing this gap as much as possible, smooth sliding without backlash.
