Assembly

Tools required for assembly

Forklift or hoist with straps/slings 14mm wrench

4mm and 8mm hex wrenches

The Lathe should be disconnected from power during assembly.

1.Remove any screws or straps that hold the Lathe parts to the pallet, and remove protective wrapping.

2.The Lathe should be located in a dry area, on a sturdy floor, and with sufficient lighting. Leave plenty of space around the machine for operations and routine maintenance work.

If you have a hoist or forklift:

3.Lift the Lathe off the pallet using a forklift or hoist, and move it to the desired location. (Forks may need to be positioned more toward the headstock to balance the weight.) Proceed to step 6 to install the legs and levelers while the Lathe is still off the floor.

If you do NOT have a hoist or forklift:

4.If a forklift or hoist is not available, the use of one or more assistants is mandatory. First decrease the weight on the Lathe by removing the headstock, tailstock and tool support base (Refer to “Headstock and Tailstock Movement” on page 13 for removal instructions).

The headstock is heavy; use caution when removing it from the lathe bed.

5.Lift the Lathe bed and set it upside down on the floor (make sure padding/cloths have been laid down to prevent scratching the bed). Or, set the Lathe bed upon a table of sufficient height to allow the legs and levelers to be assembled, as shown in Figure 1.

6.While the Lathe is off the floor, install the legs to the bed using eight socket head cap screws with eight lock washers and eight flat washers (Figure 1). Tighten the screws firmly with a 8mm hex wrench.

7.Screw the levelers into the threaded holes of the legs (Figure 1). Tighten the hex nuts against the bottom of the legs with a 14mm wrench.

Figure 1

8

8.The levelers can be adjusted at any time to ensure the Lathe is stable and level.

9.Set the Lathe right side up (or remove it from the table).

10.Exposed metal areas of the Lathe, such as the bed and spindles, have been factory coated with a protectant. This should be removed with a soft cloth and a cleanerdegreaser. Clean the bed areas under the headstock, tailstock and tool support base. Do not use an abrasive pad, and do not allow solvents to contact painted or plastic areas.

11.Re-install headstock, tool support base, and tailstock.

Comparator Rear Bracket

Mount the comparator rear bracket (A, Figure 2) to the back of the tailstock with two 3/8 x 1-1/4 socket head cap screws, two 3/8 lock washers and two 3/8 flat washers (B, Figure 2). The bracket has a slot so it can be aligned with the bracket on the headstock. (See “Comparator – Installing and Using” for further information.)

Tool Caddy

The tool caddy, shown in Figure 3, can be mounted to the left end or right end of the Lathe. The left end, near the headstock area, is generally preferred for convenience. Use two socket head cap screws and two lock washers with an 8mm hex wrench to secure the tool caddy to the threaded holes in the Lathe.

The tool caddy has holes for placing the knockout rod, spur center, live center, live center pin, comparator centers, and faceplate wrench.

Accessories can also be stored in the tailstock, as shown in Figure 4.

Guard

The guard must always be used in operations that will allow its use.

1.On the guard, loosen the set screw on the outer collar (shown in Figure 5) with a 4mm hex wrench. Slide the outer collar off the guard support rod.

2.Insert the guard support rod into the mounting bracket at the rear of the headstock, as shown in Figure 5. You will have to lift up on the spring pin, as shown, to slide the guard support rod into the mounting bracket. Release the spring pin and it will snap into position as you slide the support rod farther in.

Figure 2

Figure 3

Figure 4

Figure 5

3.Install the outer collar and tighten the set screw.

4.The guard can be pivoted to one of two positions: Operating mode (shown on front cover) or tilted back for stock loading (shown in Figure 6).

5.Pull up on the spring pin, and begin tilting the guard, then release the spring pin. When the guard reaches either of the two positions, the spring pin will engage.

Bed Extension (Optional Accessory)

An optional 18” bed extension assembly, stock number 6294727B, is available for the Lathe (see your Powermatic dealer). To mount the bed extension to the Lathe:

1.Slide the tailstock away from the edge of the bed.

2.Have an assistant hold the bed extension flush to the end of the Lathe bed, and insert three 3/8 x 1-3/4 socket head cap screws, three 3/8 lock washers and three 3/8 flat washers, through the holes in the bed extension into the threaded holes on the Lathe. See Figure 7.

3.Shift the bed extension upward so that it is slightly higher than the Lathe bed. Tighten the screws with an 8mm wrench just enough to hold the bed extension to the Lathe bed.

IMPORTANT: The surface of the bed extension must be level with the surface of the Lathe bed to allow smooth movement of the tailstock across the seam.

4.Use a dead blow mallet, or a hammer with a block of wood, to tap down the bed extension until it is flush with the Lathe bed. See Figure 8. Never use a steel-faced hammer directly against the bed surfaces. Tap the bed extension where needed until its surface is aligned with the Lathe bed, and the inside ways are aligned.

5.Firmly tighten the three socket head cap screws. Make sure your alignment of the bed surfaces doesn’t shift while tightening the screws.

6.Unscrew the stop bolt from the Lathe bed (Figure 7), and screw it into the hole at the end of the bed extension.

Figure 6

Figure 7

(optional 18” bed extension shown)

Figure 8

10

For outboard turning, where the headstock is moved to the opposite end of the Lathe to accommodate large bowl blanks, you can (1) mount the 18” bed extension to the three lower holes on the Lathe frame, and (2) mount a vertical extension post [optional accessory, stock number 3520B-310] to the tool rest base. See Figure 9.

Shelf Assemblies (Optional)

The double ledges on the inside of the Lathe legs will provide support for a shelf (not provided), which is convenient for storing larger items while keeping them easily accessible.

Figures 10-11-12 illustrate three methods of creating a shelf, using common lumber and basic tools.

IMPORTANT TIP: It is unlikely that a full-size shelf can be completely built and then inserted between the Lathe legs. Therefore, construct the shelf in pieces and insert screws only after the shelf has been established beneath the Lathe.

Shelf Style 1 (Figure 10)

Lay two 2x6 boards flat upon the inner ledges. Boards of 48” length are suitable, although 48- 1/2” is optimal.

Shelf Style 2 (Figure 11)

Lay two 2x4’s (or 2x6’s) on edge into the outer ledges. Boards of 48” length are suitable, 48- 1/2” optimal.

Cut two pieces from a plywood board, and screw them to the top edges of the 2x4’s. (One 48” plywood piece will not fit through the legs of the Lathe; use at least two pieces.) Make the plywood pieces flush with the outside edge of the 2x4’s.

Shelf Style 3: (Figure 12)

This is a basket-style shelf consisting of two 2x6’s and dowel rods. The advantage of this design is that most wood chips will fall through the shelf instead of accumulating on it. The instructions below are for building the shelf shown in Figure 12. The completed shelf is shown on the front cover of this manual.

Materials used:

2 – 2x6’s (48” suitable, 48-1/2” optimal).

8 – wood dowels, 4’ length, 5/8” diameter.

11

Figure 9

(shown with optional accessories)

Figure 10

Figure 11

1.Mark your hole centers (2” centers) along the length of a 2x6. Place the holes so that the tops of the dowels will be even with the tops of the ledges on the Lathe. Also, adjust your hole centers as necessary so that the first and last dowel will begin at approximately the same distance from the ledge at both ends of the Lathe.

2.Use a 5/8” spade bit chucked in a drill press or in a portable drill. Bore the holes through one 2x6; this will be the rear piece.

3.On the other 2x6, do not bore through but only deep enough to securely hold the ends

	of the dowel rods. This will be the front	Figure 12
	piece and will provide a pleasing
	appearance at the front of your Lathe.

4.When all holes have been bored, place the 2x6’s on edge in the outer ledges of the Lathe.

5.Cut the dowel rods to length with a miter saw or hand saw, so that after insertion the rods will be flush with the back of the rear 2x6.

6.Insert the dowel rods through the holes in the rear 2x6, as shown in Figure 12.

7.A strip of wood can be screwed to the rear 2x6 to cover the dowel holes and prevent the dowels from working out.

Grounding Instructions

Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

12

Repair or replace a damaged or worn cord immediately.

The Lathe will operate on single phase or three phase, 230 volt power supply. The Lathe should be connected to a dedicated circuit. Make sure the characteristics of your power supply match the specifications on the motor plate of the Lathe.

Single Phase Operation

A three wire pigtail for use on 230 volt single phase power is attached to the inverter and may be “hard-wired” to the power source, or connected to a UL/CSA listed receptacle plug.

Connect the 230 volt supply to the black and white leads and ground the green lead.

If you are hard-wiring the Lathe to a panel, make sure a disconnect is available for the operator. During hard-wiring of the Lathe, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the Lathe will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

Three Phase Operation

If three phase power is used, it will be necessary to replace the pigtail wire attached to the inverter with a 12/4 wire and connect the three hot leads to the inverter at R, S, T as shown in the wiring diagram on page 40. Always connect the ground lead.

Extension cords

If an extension cord is necessary, make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 13 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Adjustments

Headstock and Tailstock Movement

To slide the headstock or tailstock, swing the locking handle (A, Figure 14) backward or forward until the headstock/tailstock can slide freely. When the headstock/tailstock is positioned, rotate the locking handle to tighten it securely.

To remove headstock, tailstock or toolrest base from the bed, unscrew and remove either of the stop bolts (B, Figure 14). After re-mounting these items on the Lathe, re-insert the stop bolt.

For most turning operations, except outboard turning, the headstock should be positioned at the left end of the bed, and only the tailstock moved to accomodate the workpiece.

Cam Tightness

If the headstock, tailstock or tool rest base does not tighten properly down against the Lathe bed when the locking handle is tightened, it may need adjusting. Figure 15 uses the tailstock as the example:

1.Unscrew and remove the stop bolt on the end of the lathe bed (B, Figure 14) and slide the tailstock off the end of the bed.

2.Turn the tailstock on its side, and tighten the lock nut with a wrench. See Figure 15.

3.Mount tailstock on bed and insert the stop bolt.

Tool Support

A 14” tool support is provided with your Lathe. It is designed to allow adjustment for height, position on the bed, and angle to the work.

Loosen the locking handle on the tool support base (C, Figure 16) to slide the support base forward or back, and to angle it to the bed. Tighten the locking handle firmly before operating the Lathe.

Loosen the small handle (D, Figure 16) to raise or lower the tool support and angle it to the work. Tighten the handle before operating the Lathe.

The small handle (D, Figure 16) can be inserted into one of three holes on the tool support base. The position shown in Figure 16 is preferred so that the locking handle contacts the groove in the tool rest shaft.

Locking Handles

Each small locking handle such as D, Figure 16 can be rotated to a more convenient position. Simply lift up on the handle, rotate it on the pin, then release it, making sure it seats itself on the pin.
