This equipment is safety category 6: Other equipment with no limits.

This equipment is Noise Category 3: Can be used at all hours. No limits.

Handle with care - fragile ! Handle with care.
This is a precision tool with exact dimensions and straightness.
That means: handle it gently, don't hammer on it or use it as a crowbar and so on.
(if you need a crowbar - these are wonderful for that!)


It is very important that if you accidentally drop it or think it may be out of line

  • either mark the tool very clearly...
  • or report this to the mailing list...

...so that your fellow makers do not ruin their work.

We have several dial indicators in the metal woodshop. Consult http://www.mini-lathe.com/Measurement/Dial_indicators/Dial_indicators.htm or youtube for countless videos on how to use them. Or ask someone to show you.

I've you've never used these before (or are in doubt which one to use) then use the one in the big red box. It is the easiest and most versatile.

New dial indicator

Note that the new dial indicator has a small gib to also use the thinner size clock.

This indicator has thumbscrew to lock the dial legend (pink arrow in image below). Do NOT overtighten this bolt; it will 'lift' the entire ring forward. And with it; the legend under the dial. This in turn then blocks the hand or cause slippage.

See https://www.youtube.com/watch?v=1hZ3FVud2Bo for the (dis)assembly instructions (AKA do not just unscrew any screw in sight).
