What is the difference between UNR vs. UN Screw Threads? The UNR thread form and UN thread form are identical except that the roots of the external threads are rounded with a radius of curvature between 0.108 and 0.144 times the pitch. The rounded root improves fatigue strength compared to the UN thread form.

Note: Sanding between coats is not necessary, but it will provide a better finish. After a coat has dried, use 220 or 240 grit sandpaper or extra fine steel wool to lightly sand surface. ... Sanding produces a white film over the finish, but will disappear as you apply the next coat. Do not sand the final coat.

The difference between wood lathes and metal lathes is that the former is designed for wooden workpieces, whereas the latter supports both metal and wooden workpieces. Aside from their respective applications, wood lathes are smaller and simpler than metal lathes. Because of this, they tend to cost less as well.

The most discernible difference between discrete and process manufacturing is the way the product is created. In discrete manufacturing, identical products are duplicated by way of an assembly line. ... With process manufacturing, the end product is unable to be unassembled to its original raw materials.

Extruded acrylic costs less than cast and is more dimensionally stable, meaning the thickness is more consistent across sheets. Softer, with a lower melting temperature than in its cast form, extruded acrylic is easier to laser cut, rout, and polishes more cost-effectively.

A standard action jigsaw moves the jigsaw blade solely in an up-and-down motion, while in an orbital-action jigsaw the blade moves slightly forward and into the workpiece on the upswing, then slightly backward on the downstroke as the blade resets for the next cutting stroke.
