tale of two indicator holders

[dallen]

Wawoodman the method that I use to remove most of the material from where the indicator sits is sort of like cutting a mortise in a table leg, except that one side of the hole was open and I used an endmill to plunge straight down into the material. but first I picked up where the center of the indicator would sit and used that to locate the outside radius of the cut. there are several material removal methods that would work and most people have a couple that they use in situations like this.

Kaoma I only use the holder to do the inital centering of stock in the chuck, the holder just makes it easier to setup the indicator on the lathe, now if I am working on say a gun barrel I would use it to get close then switch to a DTI on a magbase to get it right.
