TABLE INSERT

The table insert (A) can be assembled to the saw table with the opening in the insert pointing to the front of the table, as shown in Fig. 19, or to the right as shown in Fig. 20.

With the table in the level position, 90 degrees to the blade, the insert should be positioned, as shown in Fig. 19. This allows for the blade to be pivoted forward after it is unclasped from the top blade holder, enabling you to quickly insert the blade into the next hole in a pattern when doing inside-cutting.

When tilting the table for bevel cutting operations the insert (A) should be positioned as shown in Fig. 20. This allows for clearance of the blade when the table is tilting.

A table insert blank (B) Fig. 21, is supplied as standard equipment with your scroll saw and can be used when cutting very small workpieces to give added support to the bottom of the workpiece. Cut a slot into the blank and replace the standard insert (A) with the blank (B). The slot cut into the blank (B) will only be as wide as the blade giving maximum support to the bottom of the workpiece.

CHANGING BLADES

1.WARNING: DISCONNECT MACHINE FROM

POWER SOURCE.

2. Remove table insert (A) Fig. 22, and release blade tension by pulling tension lever (B) forward, as shown.

3. Push chuck locking lever (C) Fig. 23, to the rear as shown. This will release the blade (D) from the upper chuck (E).

4. Insert long end (F) Fig. 24, of quickset blade wrench into hole (G) in lower blade holder. This will align wrench

(H) with blade holder screw (J).

5.Fig. 25 illustrates the quickset blade changing wrench (K) engaged with the lower blade holder assembly. Turn wrench counterclockwise to loosen screw (J) Figs. 24 and 25, and remove blade from lower chuck.

6.Insert new blade into the lower and upper blade holders in the same manner, making certain the blade teeth are pointing down toward the table.

7.Tighten screw (J) Fig. 26, in lower blade guard assembly.

8.Push chuck locking lever (C) Fig. 23, to the foreword position, to lock the blade in the upper blade holder assembly.

9.Replace the table insert that was removed in STEP

10.Apply blade tension by referring to the following section "ADJUSTING BLADE TENSION."

ADJUSTING BLADE

TENSION

Tension is applied to the blade when the blade tension lever (A) Fig. 27, is in the rear position, as shown. When the lever (A) is moved forward, as shown in Fig. 28, blade tension is released.

When adjusting blade tension, lever (A) should be in the forward position, as shown in Fig. 28. To increase blade tension, turn knob (B) Fig. 28, clockwise and to decrease blade tension, turn knob (B) counterclockwise. NOTE: It is necessary to adjust the blade tension knob (B) only when the blade is removed from both upper and lower blade holders and a new or different type of blade is assembled to the holders. It is not necessary to adjust blade tension when the blade is removed and replaced in only the upper blade holder as in performing inside cutting operations.

Adjusting the blade for proper tension is usually accomplished by trial and error. One method is to pull back on the blade tension lever (A) Fig. 28, the blade should start to have tension (resistance) when the blade tension lever is half way between open Fig. 28, and closed Fig. 27. Finer blades require more tensioning while thicker blades require less tension.

ADJUSTING CLAMPING ACTION OF UPPER BLADE HOLDER

Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper blade holder. It should be noted, however, that very little adjustment is necessary and very little clamping force is required to hold the blade.

1.Move the chuck locking lever (C) Fig. 23, to the rear (open) position, as shown.

2.Turn locknut (C) Fig. 29, clockwise to tighten and counterclockwise to loosen the clamping action of the, blade holder. Very little movement of locknut (C) is necessary.

TILTING THE TABLE

The table on your scroll saw can be tilted 45 degrees to the left for bevel cutting operations by loosening table lock handle (A) Fig. 30, tilt the table to the desired angle and tighten lock handle (A).

When bevel cutting, the holddown (B) Fig. 31, can be adjusted to lay flat on the stock by loosening screw (C) and tilting the holddown (B) accordingly. Then tighten screw (C).

ADJUSTING THE TABLE

1.Loosen the table locking handle, and move the table all the way to the right.

2.Using a square (A) Fig. 32, check to see if the table is 90 degrees to the saw blade, as shown.

3. If the table is not at 90 degrees to the blade, adjust the table accordingly making certain screw (B) Fig. 33, contacts bottom of table surface when table is 90 degrees to the blade. Screw (B) can be adjusted by loosening nut (C), thread screw (B) in or out the desired distance and tighten nut (C).

ADJUSTING HOLDDOWN

The holddown (A) Fig. 34, should be adjusted so it contacts the top surface of the work being cut by loosening lock handle (B) and moving holddown rod (C) up or down. Then tighten lock handle (B).

FOLLOWING A LINE

WARNING: CUT HAZARD: Keep hands away from blade. With your scroll saw you should be able to cut a straight or curved line with ease. Most beginners will experience blade wandering; however, they eventually learn to control it as they become more familiar with the machine. Use scrap material to practice cuts before starting a project. This enables you to develop your own way of cutting and you will find out what you can and cannot do with your saw.

Always hold the work firmly against the table and do not feed the workpiece too fast while cutting. Feed the workpiece only fast enough so that the blade will cut. Scroll saws cut faster across the grain than they do with the grain. Allow for this tendency when cutting patterns that shift rather quickly from with-the-graincuts tocross-graincuts.

Make "relief" cuts before cutting long curves and never attempt to cut a curve that is too tight for the blade being used.

INSIDE CUTTING

Inside cutting is where the blade must be threaded through a hole in the workpiece. The Shopmaster 16" Scroll Saw has the capability of performing this operation quickly and easily as follows:

Inside cutting can be accomplished quickly with the saw. In Fig. 36, the operator has just completed one of the inside cuts and must move to the next hole.

Fig. 36

Loosen lock handle (A) Fig. 37, and raise the spring holddown (B). Release blade tension by moving tension lever (C) forward and loosen upper blade holder by moving lever (D) to the rear as shown. This will release the blade (E). Insert the blade (E) into the next hole in the pattern, as shown.

Place blade (E) Fig. 38, back into the upper blade holder and tighten blade by moving lever (D) forward. Move tension lever (C) to the rear as shown and lower spring holddown (B). You are ready to make the next inside cut.

LUBRICATION

It is recommended that the scroll saw be oiled after each 20 hours of use, as follows:

1.WARNING: DISCONNECT MACHINE FROM POWER SOURCE.

2.Remove four screws (A) Fig. 39, and remove side panel (B) from the scroll saw.

3.Release blade tension by pulling tension lever (C) Fig. 40, forward as shown.

4.Lubricate the shafts of two special screws (D) Fig. 41, with a few drops of light machine oil in the areas where they pass through the connecting link (E). NOTE: DO NOT REMOVE SPECIAL SCREWS TO LUBRICATE.

5.Remove two pivot bolts (F) Fig. 42.

6.Thoroughly clean grease from shafts (G) Fig. 42, of both pivot bolts (F) and lubricate shafts (G) with a few drops of light machine oil.

7.Reassemble two pivot bolts (F) Fig. 42, to machine.

8.Replace side panel removed in STEP 2 and reapply tension to the blade.

CHOICE OF BLADE AND SPEED

Your scroll saw will accept a wide variety of 5" flat end blades and can be operated at any speed from 400 to 1800 cutting strokes per minute. Consider the following as a general guideline for selecting a blade and operating speed.

1.Use a finer blade for cutting thin workpieces, for hard materials, or when a smoother cut is required.

2.Use a coarser blade for cutting thick workpieces, when making straight cuts or for medium to soft materials.

3.Use a blade that will have 2 teeth in the workpiece at all times.

4.Most blade packaging is marked with the size of the wood the blade is intended to cut and the minimum radius which can be cut with that blade.

5.Slower speeds are generally more effective than faster speeds when using thin blades and making intricate cuts.

6.Always start at a slow speed and gradually increase the speed until the optimum cutting speed is obtained.

TROUBLESHOOTING - BLADE BREAKAGE

Blade breakage is usually caused by one or more of the following:

1.Bending the blade during installation.

2.Improper blade tension.

3.Improper blade selection for the work being cut.

4.Forcing the work into the blade too rapidly.

5.Cutting too sharp a turn for the blade being used.

6.Improper blade speed.
