Two-axis positioning stage with leadscrew and nut seats

Move a small specimen in two directions without relocating the whole setup. Base, middle plate and top platform form two stacked dovetail slides. Platform size and total travel in each axis are chosen before manufacture. Add two M4 threaded rods or suitable long screws, two M4 nuts for the open pockets, washers, locknuts and your own turning knobs. Each screw must rotate freely in its fixed support while washers and locking nuts on both sides retain it axially. Insert the lower guide first, then the upper one. The four top 2.7 mm blind pilot holes are only 3 mm deep: use suitable short screws. Bolt down the base and limit motion to half the configured total travel on either side of centre. For light learning and positioning tasks, without calibrated accuracy or suitability for milling. Adjustable values: Top-platform side length: 40–70 mm; Intended total X travel: 8–20 mm; Intended total Y travel: 8–20 mm; Printed-guide clearance: 0.2–0.4 mm; Spacing of the four top blind pilot holes: 12–24 mm.
