1) What is Craftsman Oscillating Spindle Sander? Craftsman Oscillating Spindle Sander (COSS) is a self-propelled sanding machine designed for use on wood, metal, plastic and other materials.
COSS is equipped with two rotating blades which are operated independently of each other. These blades are capable of cutting through material at different speeds. COSS is able to cut through various thicknesses of material with ease.
The machine was developed by a company called Dorna Industries Ltd., based in England. It was first introduced in 1995 and since then it has been sold all over the world.
2) How does it work? When you turn the handle on top of the machine, it starts moving forward.
When it reaches its maximum speed, it stops and turns around to start moving backward again. You can control how fast or slow the machine moves by turning the handles located on either side of the front wheel. The speed of movement depends upon whether you want to move forward or back along a path marked out by a series of buttons located just above your right hand thumb.
Along the top of the machine is a slightly elevated platform with a handle on either side. It is tilted slightly forward and is used to carry the machine from place to place. The most important thing on this platform, however, is the toolrest located at the center. This toolrest holds a variety of attachments that can be used to sand, grind and polish wood, metal, plastic and other materials.
When you place the machine on the workpiece, the material to be sanded is placed upside down along the back of the sander. Then, the machine is slowly moved forward as the attached disk spins against the surface of the material. This disks have plenty of abrasive material attached to it which cuts into the wood, metal, plastic or whatever material you are working with. The materials from this disk are then forced against the disk behind it and they are chopped into tiny pieces.
