Here is a music stand I designed loosely on a shaker candle stand. It can be adjusted vertically or horizontally.
I saw a shaker candle stand that was vertically adjusted via a notched center piece that ratched up and down as desired. This music stand incorporates the ratchet adjustment with the Shaker three legged base.
To raise or lower the stand, the aluminum adjusting rod is lifted up and backard in the inverted "L" slot. LEFT.
The stand is raised or lowered to desired height, then the rod is slipped back into a slot in the verical riser and is locked down into the inverted "L" BELOW
Horizontal adjustment is made by loosening/tightening the wing nut on the steel mounting bracket.
