A few days ago I came across a slot cutter with 30mm diameter and 4mm blade height and asked myself whether this would be suitable to cut threads in wood? So I decided to give it a try and make a small wooden box with a 120 x 8mm thead.
Step 1: Material
The tin is made of 2 blocks 160 x 160 x 45mm beech plywood glued together from 15mm blanks...
Use quality wood - if you look closely the wood I used has a few bad spots that just closely missed the thread...
Step 2: Machining
The machining steps are shown in the video at the beginning.
The CAM and CNC control software used is Estlcam.
