Operation

Before using your drum sander, review the previous pages in this manual on initial set-up and adjustment. In this section, you will learn how to operate the machine. Make sure an abrasive strip is mounted and a dust collection system is connected.

Basic Operating Procedure

1.Set depth of cut.

2.Start dust collection system.

3.Start drum.

4.Start conveyor and select feed rate.

5.Feed stock through machine.

To feed stock through the 22-44 Pro, rest and hold the board to be sanded on the conveyor belt, allowing the conveyor belt to carry the board into the drum. Once the stock is halfway through, reposition yourself to the outfeed side of the machine to receive and control the board as it exits.

Setting Depth of Cut

Adjusting the drum sander for the proper contact between the abrasive and the stock determines the mechanical depth of cut.

It may take some experimentation to determine the proper depth of cut, given the variables of abrasive grit, type of wood, and feed rate. For best results, use scrap wood to practice sanding and to develop skill and familiarity with the machine before doing finish work.

A combination of several variables will determine the proper depth of cut to use, including the following:

1.Abrasive type and grit size.

2.Width of the piece being processed.

3.Hardness of the piece.

4.Feed rate of the conveyor belt.

Establishing Proper Drum Height

The depth of cut is controlled by the table height adjustment handle which raises or lowers the conveyor table under the drum.

A good rule of thumb when sanding with grits finer than 80 is to place the stock to be sanded under the drum and raise conveyor table until the drum contacts the stock. Drum should still rotate by hand. Without changing drum height, finish feeding the stock under the sander.

Start sanding drum and sand the stock at that same position.

Do not start drum while in contact with stock!

For sanding with grits coarser than 80, you can raise the conveyor table slightly.

Always maintain control of stock. Through practice you will learn the proper depth of cut considering the variables above.

Selecting Feed Rates

Selecting proper feed rate is an essential step after first adjusting for depth of cut. The variable feed rate controller of the conveyor belt adjusts the load on the machine; it can be infinitely adjusted within its specified range for maximum operating performance. A faster feed rate allows faster sanding but fewer revolutions of the drum per inch of sanding. A slower feed rate provides more revolutions of the drum per inch of sanding to allow a greater depth of cut and smooth sanding.

Begin experimenting with the feed rate set at about 40% to 50% of maximum. The best feed rate will depend on a number of factors, including type of stock, grit and depth of cut used, and whether the stock is fed directly in line with the conveyor bed or at an angle. If the drum motor is lugging down, if the conveyor belt is slipping, or if you observe a ripple effect on the stock, slow down the feed rate. If the finish is smooth and the machine is not overworking, you can experiment with using a faster feed rate.

Also try a faster feed rate or less depth of cut if the stock you are working begins to show burn marks. With cherry, hard maple or other hardwoods, using a shallower depth of cut and a faster feed rate will help minimize burn marks. Slightly angling the stock as it is fed into the machine will also help prevent burning the stock.

Because of the wide range of variables, it is important to experiment with your specific conditions and make adjustments to achieve the optimum feed rate. If problems occur, first check and adjust the feed rate, referring to the “Troubleshooting” sections in this manual.

Tips for Maximum Performance

The versatility designed into the 22-44 Pro drum sander allows it to be used for a wide variety of tasks that will boost the return on your investment. For example, its capabilities range from taking the place of a planer to thickness rough stock, to speeding up fine sanding work often done with slower, dust-generating hand sanders.
