Pretty straightforward.
3mm ply. Clear PVA glue.
The dials are a fairly tight friction fit and care is needed when adjusting them.
I am not sure what might be applied to the dials or dial holders to ease the movement.
Perhaps the writing should have been filled to aid viewing from a greater distance away.
But an acceptable first one produced.
Obviously can be customised and certain areas can be sprayed with colours or clear finishes.
