Square gears from plywood
A friend said like acoo kie, his wife said some windows :) And yet they spin!
I did not come up with square gears, I just repeated. Recently I collected a CNC machine tool and I really wanted to cut out such gears from plywood.
For those who want to cut out such gears, I attach g-code for the machine. In the archive there are two versions of the gears and the source files dxf.
Today, instead of round guides, the printer received square, using a conventional aluminum profile tube with a cross section of 20 * 20 mm. Bearings roll along the pipe 623zz. All plastic parts were printed on the same printer before it was altered.
This small turntable is needed when you need to photograph something or shoot a video in 360 degrees. For the assembly you will need an old CD-drive, a couple of pieces of plywood, a box for batteries, a switch, wires and other trifles.
The idea of assembling a homemade CNC machine appeared long ago. Lack of knowledge and necessary details. Today there is everything!
It all started with the fact that I had a daughter :) Now she is 1.3 years old and she has already learned to deftly sit down to her daddy on her knees and read a book. Each child, like an adult, should have his own chair. Searches in children's shops were unsuccessful, the chairs are all plastic and large or with a hole for the pot. We needed a normal chair for sitting, for a very small girl.
The eternal problem, which wire to connect :)
