I used a flexible arm that is normally used to hold photo accessories on a tripod or light stand. They are available on line and the better camera stores. That arm is the main part. Made an adapter for one end of the arm to thread into one of my magnetic indicator holders and the other end was set up with a threaded rod that fits into the aluminum clamp that holds the "free" HF flashlight. I also had a piece of a small milling table that was not being used so I thought it would make a good heavy base so the light may be used on any type of surface. Works fine and is very versatile anywhere in the shop.
