DOORS AND MILL WORK

When sanding doors, cabinet frames, sash, storm windows and screens, take care to avoid working into the cross grain where one member meets another. Notice that the right edge of the belt is visible on the sander. Work carefully along the edge where the rail meets the stile. If the joint is slightly uneven, use a fine abrasive and very light sanding pressure to smooth it before making finishing runs.

For lengthy work on walls or other vertical surfaces, balance the tool with a length of sash cord, two small pulleys, a light wood frame, and a weight that is the same as, or slightly less than, the weight of the sander. The frame consists of two pieces leaning against a wall with a third piece nailed to their top ends. The two pulleys are located so that the weight on one end of the cord will be out of the way, but will balance the sander fastened to the other end. When starting vertical work, angle the sander so you can see that the belt makes contact with the material. As the belt touches, level the machine and make the stroke away and to the left. This movement will offset the tendency to cut heavily into the work at the start of the stroke.

GOOD SANDING TECHNIQUE

Getting to know the sander is most important in obtaining smooth results with a minimum of labor. Operators will quickly learn how to start a stroke with a sweeping motion to produce the best results. Use a long even stroke without additional pressure on the tool. Overlap each stroke and vary the length of movement so the results will be even. Always lift the tool from the work before starting and stopping the motor.

BE CAREFUL when sanding at the end of a board. Keep the tool level and flat on the work surface. Don’t let the front of the tool drop. (Fig. 6). If this happens, it will round the edge.

The model 352VS sander works very fast and can do a thorough job in a fraction of the time required by hand sanding. Do not rush the job. Give every surface a thorough sanding with each grade of abrasive before changing to finer grits. Always use the abrasive material and grit size recommended for the particular job.

SANDING METAL

Use the Belt Sander to obtain a grained satin finish on metal. A special graphite pad is available to replace the steel shoe on the bottom of the sander. The softness of this pad aids in blending the graining. The pad is the proper length for sanders using a 3" x 24" belt. For sanders using shorter belt lengths, cut the pad so that it is the same length as the steel shoe. Replace the steel shoe with the graphite pad.
