How would be the best, easiest, cheapest way to make two tubes adjustable? Answered
I need to get two small tubes (one slightly bigger then the other) and to have each hold a lens and be adjustable (rotationally)? That is, they rotate along the axis of the tube (as if holding the two lens near one another and turning one). I have several options and am not able to purchase anything at the moment (or I'd get some small plastic piping that fit fairly well together).
