Lathe DRO by Marc M -- Homemade DRO for a small lathe. Chinese 12" calipers are mounted on a cam-lock style mount on the lathe way. The opposite end is secured to the mounting block on the carriage with a thumbscrew. http://www.homemadetools.net/homemade-lathe-dro
DIY drawer organizer project ~ 48" wood laths super-cheap at Home Depot, & the store will cut them for you. So simple it's not even really a tutorial :-) Would also work to make a shadowbox to display small items.
