I found a handheld enclosure at Pasar Road. The size is just nice for my applications.
All the switches will be mounted at the bottom below the display area. The display area will be covered with 1.5mm aluminum plate and the MPG will be mounted on it.
I have yet to plan how many switches on the pendant.
Now, I already have the work holding clamps made from mild steel.
I also added a corrugated board onto the to chips when milling. I hope this will work and keep my floor clean.
