Trying to make Q-ball scales
Posted: Sun Jan 18, 2026 9:08 pm
So I'm working on making scales for my Q-ball on a 3018 desktop cnc router and thought I would share along the way.
For CAD and CAM I'm using Fusion 360. The model is pretty straight forward.
The CAM software makes the tool paths with a few selections. Not as hard as I imagined when starting this.
Getting the feeds and speeds right for the tooling and rigidity of the machine is tricky. The 3018 isn't very rigid and doesn't like full cutter engagement when cutting the profile so I have to take it slow.
I decided to do some fitment tests with G10 liner material. I'm glad I did as there was some issues and the model needed scaled down by .5mm oal. Also my feed rate on the profile was too high.
The second test went a lot smoother. It's still off in a few areas. The countersinks are slightly larger on the side without screws and it's a little short near the ricasso.
I'm going to make a few adjustments and update this when I have both sides done. I only had one set of orange liners so the next ones will be blue or white.
