This model of the Unimat 1 has many plastic parts and plastic machining cross slides. It is capable of working wood, plastic and soft metals i.e. aluminum and brass. It is the same machine as the basic with additional capabilities such as wood turning, sawing, drilling, milling and metal turning.
Machine tapers for tool holding included Morse tapers (on early models) and the R8 taper (a widely used standard that Bridgeport created) on most models. Both Morse and R8 allowed for both collets and solid holders, and a drill chuck could be held by either of the latter. Currently R8 and Erickson #30 Quick Change tool holders are available.

Working from engineering drawings developed by the toolmaker, engineers or technologists, tool makers lay out the design on the raw material (usually metal), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, and jig grinders), power tools (such as die grinders and rotary tools), and hand tools (such as files and honing ...
Livelihoods based on model engineering include retailers who provide model engineers with equipment and supplies, small fabrication services who produce castings, make miniature live steam boilers and live steam kit parts (or even whole running models), commercial publishers in the model engineering press, and a very few professional model ...
The hobbyist starts by constructing a small foundry capable of melting silicon-aluminum and zinc alloys from recycled automotive parts. Then green sand castings are used to make a metal lathe. The lathe is the first machine built since it can be used to help build itself. The lathe and foundry are then used to make more complicated machine tools.
Model #2 Square Base, four-slide machine. 1 1 ⁄ 2 cap or 1 3 ⁄ 4 Air Feed. Screw machines, being the class of automatic lathes for small- to medium-sized parts, are used in the high-volume manufacture of a vast variety of turned components. During the Swiss screw machining process, the workpiece is supported with a guide bushing, near the ...
