Laser Cut Reciprocating Rack and Pinion

thingiverse

This is an incredibly simple laser-cut, fully operational reciprocating rack and pinion gear system that is precision-cut from .194" (5mm) MDF and .160" (4mm) acrylic. You can use MDF for all parts, but creating the rack gear from acrylic makes it slide smoothly. The necessary items for this build include: 1 piece 2' X 2' .188" (5mm) MDF 1 piece 12" X 6" .160" (4mm) acrylic (optional, use 5mm MDF for all parts) 1 piece 1.0" (25.4mm) long, 3/8" diameter wood dowel 1 piece 2.5" (64mm) long, 3/8" diameter wood dowel wood glue To assemble this system, view the instructions here: https://youtu.be/YegS5bKZgSw Make sure to SUBSCRIBE HERE: https://goo.gl/sYY9mu Invention Therapy is a show that turns your ideas into reality!
