I'm getting into turning with a lathe, starting small with some decent-used tools from the local ebay(trademe) and some janky chinese-grade tools. But I want to learn Best Practices. Right now I have one mag base/noga-style arm, and one dial indicator, and one test indicator.
How should I store a magnetic base and a dial indicator to prolong their life and retain accuracy?
These have a circular core which can rotate 90 degrees. In the on position there's a solid magnetic field from the underside, to hold the base on a ferrous surface like a lathe, drill, mill, or similar Big Tool. When off, there is minimal magnetic attraction so the unit can fall over, but it won't attract metal chips and filings.
- do I store the mag base in the ON position, clamped to a metal surface? Or do I store it OFF?
- should the unit be vertical or horizontal or doesn't matter?
- should I leave the dial indicator in the mag base permanently or return it to a shelf?
(mine are all sub $20 items, so the boxes aren't good for long-term storage.)
