I know I seen one on the net. but can not remember what they are called Ill try to describe it.
Its used to gauge sizes on your turning in multiple places-
It has several thin flat bars on a rod and the rig is behind and above the turning so the bars lay on their edge on the turning.
You can set each flat bar at different spot on the guide bar + each of the flat bars are adjustable in and out,so as you size with your parting tool and you get to the set diameter the bar falls past the turning.
What are they called ?Were can I get one or look at one so I can make my own.
Thanks Ron seizer

I found it called a " Semaphore Jig" adjustable bars that drop through when you cut to a set depth.
Found a brief description in a "Craftsman Power Tool Know How" book

Ron, Imagine a shower curtain rod positioned parallel to the bed of the lathe. back away from the rear and up about 4" above the bed.
Instead of hanging a curtain you hang teardrop shaped cams of 1/8" baltic ply between each cam, place a spacer and set screw to hold cams in the proper location.
When turning grooves (with parting tool), these cams will drop down and away when you've reached the correct depth.
Naturally, you'll have to make several different sizes of these cams and mark their sizes on each cam.
Once you've Laid out the first spindle depths and positions, turn each groove in the first piece,then groove piece #2/ 3/ #4 etc etc/ Stein.

Sorry about being slow on the response, it is the FWW book, Lathes and Turning Techniques, article is titled Efficient Spindle Turning, by Steve Gellman, I'm working on a pic-js
