Location

In the top drawer of the red-metal cart in the metal workshop.

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

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

Handle with care - fragile ! Handle with care.
This is a (precision) measurement 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.

God save the queen! WARNING: Imperial tools have slightly different sizes than Metric ones.

Using the wrong one will often damage the bolt, nut or whatever you are working on. See this list for all the imperial tools we have.


Try not to mix them with our metric tools -- to make sure your fellow maker does not ruin their work.
Be especially careful with the close friends, such as sizes like 5/8inch and 16mm;
although the difference is 0.13mm - you will ruin (or usually just crack) a collet or similar..
