Assembly

Tools required for assembly

Forklift or hoist with straps/slings 14mm wrench 4mm and 8mm hex wrenches

The Lathe should be

disconnected f rom 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 locat ed in a dry area, on a sturdy floor, and wit h sufficient lighti ng. Leave plenty of space around the machine for operations and routine maintenance work.

If you have a hoist or forklift:

3. Lif t the Lat he off the pall et using a fork lift or hoist, and move it to the desired location. (Forks may need to be positioned more toward the headstock to balance the weight.) Proc eed 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 av ailable, 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 head stock is heavy; use

caution when removing it from the lathe bed.

5. Lift the Lathe bed and set i t upsi de down on the floor (make sure padding/cloths have been laid down to prevent scratching the bed). Or, set the Lat he 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 usi ng 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 (F igure 1). Tighten t he hex nuts against the bott om of the legs with a 14m m wrench.

Figure 1

8. The lev elers 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 tabl e).

10. Ex posed metal areas of the Lat he, 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-inst all headstock, tool support base, and tailstock.

Comparator Rear Bracket

Mount the com parat or rear bracket (A, Figure 2) to the back of the tailstock with t wo 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 wit h the bracket on the headstock. (See “Com parator – Installing and Using” for further information.)

Figure 2

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 c enter, live center, live c enter pin, compar ator c enters, and faceplate wrench.

Accessories can also be stored in t he 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 coll ar (shown in F igure 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 lif t up on the spring pi n, as shown, to slide the guard support rod into the mounting bracket. Release the spring pin and it will snap i nto posi ti on as you sl ide t he support rod far ther in.

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 Figur e 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 m ount 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 ex tension upward so that it i s slightly higher than the Lathe bed. Tighten the screws with an 8mm wrench just enough to hold the bed extensi on to the Lathe bed.

IMPORTANT: The surface of the bed extension must be level with the surface of the Lathe bed to allow smooth m ovement of the tailstoc k across the seam.

4. Use a dead blow mallet, or a hammer with a block of wood, to tap down the bed extension unti l it is flush with t he 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.

Figure 6

Figure 7

(optional 18” bed extension shown)

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 t he hole at the

Figure 8

end of the bed extension.

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 ex tension to the three l ower 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 keepi ng 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 com pletely built and then i nserted between the Lathe l egs. Therefore, construct the shelf in pi eces and insert screws only after the shelf has been established beneath the Lathe.

Shelf Style 1 (Figure 10) Lay two 2x6 boards f lat upon the inner l edges.

Boards of 48” l ength are suitable, al though 481/2” is optimal.

Shelf Style 2 (Figure 11) Lay two 2x4’s (or 2x 6’s) on edge int o the outer

ledges. Boards of 48” length are suitable, 481/2” optimal.

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

Figure 9

(shown with optional acc es s or ies )

Figure 10

Shelf Style 3: (Fi gur e 12) This is a basket-style shelf consisting of two

2x6’s and dowel rods. The advantage of this design is that m ost 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 t his manual.

Materials used:

2 – 2x6’s (48” suitable, 48-1/2” optimal). 8 – wood dowels, 4’ length, 5/8” diameter.

Figure 11

1. Mark your hole centers (2” centers) along the length of a 2x6. Pl ace the holes so that the tops of the dowels will be even with the tops of the l edges on the Lat he. Al so, adj ust your hole center s 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 c hucked i n a dri ll press or in a portabl e dril l. Bore t he holes through one 2x6; this will be t he r ear pi ec e.

3. On the other 2x6, do not bore through but only deep enough to securel y hold t he ends of the dowel rods. This will be the front piece and will provide a pleasing appearance at the front of your Lathe.

4. When all hol es have been bored, place t he 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 t hat after i nsertion 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 Fi gur e 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 mac hine m ust be grounded. I n the event of a malfuncti on or break down, groundi ng prov i des a path of least resi stance f or electric current to reduce the ri sk of el ectri c 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 r epair or replac em ent of the electric cord or plug is necessary, do not connect the equi pment-grounding conduc tor 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.

Repair or replace a damaged or worn cord immediately.

The Lathe will operate on single phase or three phase, 230 v olt power suppl y. The Lat he shoul d be connected to a dedi cated circuit. Mak e 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 attac hed to the invert er and may be “hard-wired” to the power source, or connected to a UL/CSA listed r ec eptacle 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. Duri ng hard-wiring of the Lathe, m ake 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 c onnect the three hot leads to t he inver ter at R, S, T as shown in the wiring di agram on page 40. Always connec t the ground lead.

Figure 13

Figure 14

To remove headstock, tailstock or toolrest base from the bed, unscr ew and rem ove ei ther of t he stop bolts (B, Figure 14). After re-mounting these items on the Lat he, 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, t ailstock or tool rest base does not tight en properly down agai nst the Lathe bed when the locking handle is tightened, it may need adjusti ng. Figure 15 uses the tail stock as the example:

1. Unscrew and remove the stop bolt on the end of the lathe bed (B, Figure 14) and sli de the tailstoc k off the end of the bed.

2. Turn the tailstock on i ts side, and tighten the lock nut with a wrench. See Figur e 15.

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

Tool Support

A 14” tool support is provided wit h your Lat he. I t is designed to allow adjustment for height, position on the bed, and angle to the work.

Figure 15
