Working with Metric Dimensions
The drawings included with our models show all dimensions in
millimeters. For your convenience, we've provided a conversion
tool below. Simply type the metric dimension in the left box,
click the arrow button, and your answer appears on the right.
A Better Solution
Rather than converting all dimensions to inches, why not do
what the rest of the world does: work in millimeters!
Keep in mind that most imported mini lathes and mini mills
are metric in design and construction. (For example, the
compound rest feed handle on some models has 40 divisions, and
each turn of the handle supposedly advances the compound rest
0.040". In fact, each turn advances the compound rest by exactly
1 mm, which is 0.03937".)
work comfortably in metric units, you'll need metric measuring
tools. Start with an electronic digital caliper, which switches
between display of inches and millimeters with the press of a
button. Several models are available from
LittleMachineShop.com and other online vendors.
