Made a new dial indicator holder for my mill. I started with a small Noga holder and the clamp part of my indicol setup.
I started the adapter with a 30-degree taper which will reside in the Indicol spindle mount.
I then tapped 6mmx1.0 threads into the adapter and threaded a rod to be used with a knurled thumbnut.
Threading the stud.
Stud threaded.
Adapter, stud, small taper and knurled thumbnut shown.
I then moved over to the milling machine and installed the adapter into a collet block to machine the flat on the adapter and to drill/tap the 5mmx.8 hole.
Adapter completed and installed into the Indicol spindle mount bracket.
NOGA NF61003 removed from the magnetic base and threaded onto the adapter and Indicol mount.
Installed on spindle and tested.
Works perfect and is rock solid. Much more rigid than the Indicol mount/arm ever was. This allows me to indicate on a part or in a hole without having to remove the tooling from the spindle. NOGA does manufacture a smaller arm like this one that has a 3/8" stem but you have to remove whatever tooling you are using and install either a 3/8" collet or drill chuck to accept the stem. This way there is no need to remove whatever tooling you have installed in the spindle.
