Getting Ready!

Preparing Your Machine for Operation

Moving the Machine

Moving a machine tool can be dangerous. Improper techniques and methods may injure you and/or damage the machine. To find a professional to move and site your Smithy machine, look in your local Yellow Pages under “Machine Tools, Moving and/or Rigging”. If there is no such listing or your community does not have a rigging specialist, a local machine shop or machinist may be able to provide referral.

When you pick up the machine at the shipping terminal, bring a crowbar, tin snips for cutting the metal straps, and a hammer. If there is obvious shipping damage to the crate, you’ll be able to inspect the machine before signing for it. Note any damage on the bill of lading (shipping document). Fill out the claims forms and notify both Smithy Co. and the shipping terminal about the damage. Failure to notify both parties can complicate and/or invalidate a claims process. Trucking company terminals usually have forklifts to assist customers. It’s most convenient to transport the machines in trucks without canopies and large vans.

Un-crating and Positioning the Machine

Note: Tip the crate from the tailstock end up and over the machine.

The machine is assembled, inspected, and ready to do in its stand. It’s wrapped in a water and greaseproof cover, strongly braced, and crated. A box of accessories is also in the crate.

The metal bands that encircle the crate are under tension. Wearing eye protection and gloves cut the metal bands with tin snips. Caution

The cut edges are sharp. The bands secure the crate top to the base.

After removing the straps, lift off the crate top. Tip the crate from the tailstock end up and over the machine.  Do not damage the crate. You may need it another time to transport the machine.

Once your crate cover is removed it is time to put your machine on its bench. The machine is just less than 650 pounds so make sure you have some extra hands to help. There are four lifting pints that pull out from the bed of the lathe. You can use chains or a tow rope to wrap around these pins and the aid of a lifting device such as an engine hoist to lift the machine on to a bench rated to support the machine’s weight.

Without a mechanical device to aid in your lifting you can lighten the machine by removing a few or all of the following:

Millhead

  1. Remove the four hexagon socket-head screws at the base of the millhead support  column. If a screw runs through the belt box into the flange of the support column, remove it too.
  2. Lock the millhead-locking handle.
  3. Lift the millhead and column off the lathe head. You may have to rock it back and forth while lifting it. Make sure that the mill head is locked to the column before removing the millhead.

Tailstock

  1. Loosen the tailstock lock and pull the tailstock off the end of the bed. The gib and locking pin will fall out. Be careful not to lose them.  

Bolts

Figure 5.2 The chuck attaches to the spindle flange with three bolts.  The one bolt located on the other side of the spindle does not show.

Three-Jaw Chuck

  1. Remove the three bolts behind the chuck that hold it to the spindle flange (Figure 5.2).

The chuck will come off. Don’t let it fall onto the ways. Placing a board between the chuck and ways will protect the ways.

Place the machine on a strong, rigid table 40” long, 24” wide and 28” to 33” high. We recommend you to bolt down the Granite machines using the holes in the base of the bed or using the lifting handles as they held the machine to the shipping pallet.

Selecting a Location  

There are several major considerations for selecting a location for your Smithy.  Operation is from the apron side, so allow at least 40” to 48” clearance in front of the machine.

The machine should be on a 20-amp circuit, positioned as close as possible to the power supply. Try not to use an extension cord. If you must use one, check with an electrician about the proper size.

Provide ample working light over the operator’s shoulder.

Check along and across the bed to make sure it is level.

Place the machine on a solid foundation, concrete if possible. If you must put it on a wood floor, make sure it is adequate. Brace it if necessary to prevent sagging or settling.

Make allowances at the back of the machine tool as at its end and above it for later additions, attachments, and/or accessories. Provide clearance on the left end for bar stock to be fed through the spindle. If you are considering placing more than one machine in an area, allow enough floor space to feed long bar stock to each machine. Notice To check bench and bed level accuracies, successively place level at A, B, C, D  (longitudinal positions) and E and F (transverse positions). Bedways alignment in the longitudinal place should be better than 0.0016/40”; alignment in the traverse plane should be better than 0.0024/40”.  

Cleaning and Lubricating the Granite Machine

Smithy machines are shipped with protective grease coating called cosmoline. Use WD-40 or non-corrosive kerosene to remove the cosmoline.

Once you have your Granite set up and positioned correctly, you are ready for lubricating. You must do this carefully and thoroughly before starting the machine.

Use a pressure oil can and a supply of good quality SAE No.10 weight oil.

To be thorough and complete, follow this routine:

Oiling the Ways

Run the carriage as far to the left as possible. Put a few drops of oil on the ways. Run the carriage to the extreme right and repeat. You may want to use Way Lube, special oil formulated for the ways.

Oiling the ways

Oiling the Millhead Quill

Use the mill handles or fine feed crank to lower the millhead down.  Apply a thin layer of oil to the quill and work it down and up until it runs smoothly.

Oiling the Headstock

Oiling the Millhead Quill

Oil the button behind the D gear.

Or Visit www.smithy.com

Open the gearbox door to expose the pick-off gears. Oil the button in the casting behind the D gear. Then put a few drops of oil on the teeth of all the gears.

Grease the zerk on the A gear shaft.

Check the sight glass under the chuck. If necessary, add oil until it is half full. The oil fill plug is at the back of the headstock above the motor. Be careful not to overfill it. The gearbox requires only 8 to 10 ounces of oil.

Oiling the Carriage

Lubricate the oil buttons in the cross feed table. There are two buttons on the left of the saddle for the bedways and two on the front of the cross slide for the cross slide ways.

Oil the button in the center of the cross slide.

Put a few drops of oil on the compound slides.

Oiling the table

Oiling the Compound Angle Toolpost

Oil the buttons along the cross feed table.

Oil two buttons on top of the compound angle toolpost.

Oiling the Apron

Put oil in the button just behind the cross slide hand wheel.

Put oil on the button at the back of the cross slide.

Oiling the Leadscrew

Put oil in the oil buttons on the left trestle.

Put oil in the support for the right end of the leadscrew.

Oiling the Tailstock

Oil the two buttons on the top of the tailstock.

Oil the buttons on top of the tailstock.

Oiling the Mill/Drill Clutch

Oil the clutch housing button.

Put oil in the button on top of the clutch housing.

Notice!

To keep your machine in peak condition, lubricate it daily after removing any debris.  Do not fill the gearbox sight glass more than half way. Too much oil will make the motor lug and sling oil out from behind the chuck and inside the belt box.

Figure 5.2 Installing Arbor Plug  

Install the plug setscrew (S12898 into the tailstock arbor before inserting the arbor into the tailstock. A plug is installed in the tailstock arbor (the MT3 to JT33 arbor, part number C30523), which allows the ejector pin inside the tailstock to eject the arbor when the tailstock barrel is retracted.

Morse Taper 3 (MT3) tooling is used in the tailstock of the machine. R-8 tooling is used in the millhead of the machine and used in conjunction with a drawbar.

Mill Spindle Cover

WARNING!

Do not operate your machine without the mill spindle cover. Doing so could cause harm to yourself or your machine.  

Handles

Figure 5.4 Installing Handles

Install any handles or hand wheels that have been removed for shipping. Handles can be hand installed and tightened with a flat-head screwdriver. Remove and reverse the tailstock handwheel.

Cleaning & Lubricating Your Machine

Smithy machines are shipped with a light protective grease coating that must be removed prior to use. Use a noncorrosive kerosene or white mineral spirits to remove the coating. WD-40® also works well.

Once cleaned, your Smithy must be lubricated. Make sure to lubricate carefully and thoroughly before starting the machine. Use a pump oil can and a supply of good quality SAE30 weight non-detergent oil or 30-weight compressor oil. Lubricants can be obtained at most home and building supply stores. A lubrication point chart can be found on the backside of the millhead.

Lubrication Schedule  

Lubrication depends a lot on the use of your machine and your climate. The schedule below is intended to be used as a guide, use your best judgement for lubricating your machine based on your use and environment.

Check Oil Before each use

Oil Ports Before each use

Adjusting Gibs

The Granite 1300 models have a series of straight gibs. The gibs are found on the carriage, the cross-slide table, compound angle toolpost and the tailstock.

These gibs should be adjusted periodically to maintain accuracy and smooth operation.

! NOTICE !

Always make sure your machine is well lubricated before adjusting the gibs.

Carriage Assembly-Saddle

Adjust the gibs on the saddle assembly using the procedure below.

Figure 5.17 Carriage Gibs

Step1: Loosen the four jam nuts on the back side of the saddle with the 6” adjustable wrench that was shipped with your machine.

Step 2: Back out the gib adjusting screws found on the back side of the saddle two turns with the 4 mm allen wrench.

Step 3: Using the 4 mm Allen wrench, tighten each of the four gib adjustment screws until they are lightly touching the gib.  

CAUTION  

Do not apply excessive force.

Step 4: Back the gib adjustment screws out 1/8 to 1/4 turn.

Step 5: With the adjustment screws now set at roughly the same position, make the fine adjustments on each individual screw. Starting with one of the inner screws, slowly tighten the screw while moving the carriage assembly by turning the leadscrew handwheel until you feel slight resistance.

Step 6: Once slight resistance is felt, hold the gib adjustment screw in position and tighten the jam nut.

Step 7: Repeat steps 5 and 6 with the other inner screw and then with the two outer screws.

Adjusting the Gibs on the Carriage Assembly Cross-Slide Table

Adjust the gibs on the cross-slide table using the procedure below.

Figure 5.18 Gib Adjustment Screws - Cross-Slide Table

Step 1: Loosen the four jam nuts on the tailstock side on the table with the 6” adjustable wrench that was shipped with your machine.

Step 2: Back out the gib adjusting screws two turns.

Step 3: Using the 4 mm Allen wrench, tighten each of the four gib adjustment screws until they are lightly touching the gib.

CAUTION  

Do not apply excessive force.

Step 4: Back the gib adjustment screws out 1/8 to 1/4 turn.

Step 5: With the adjustment screws now set at roughly the same position, make the fine adjustments on each individual screw. Starting with one of the inner screws, slowly tighten the screw while moving the cross-slide table by turning the cross-slide handwheel until you feel slight resistance.

Step 6: Once slight resistance is felt, hold the gib adjustment screw in position and tighten the jam nut.

Step 7: Repeat steps 5 and 6 with the other inner screw and then with the two outer screws.

Adjusting the Gibs on the Compound Angle

Toolpost

Adjust the gibs on the compound-angle toolpost using the procedure below.

Figure 5.19 Gib Adjustment Screws - Compound Angle Toolpost

Step 1: Loosen the jam nuts on the side of the compound-angle toolpost with the 6 inch adjustable wrench.

Step 2: Back out the gib adjustment screws out two turns.

Step 3: Using the a flat-head screw driver, tighten the two gib adjustment screws until they are lightly touching the gib. CAUTION  

Do not apply excessive force.

Step 4: Back the gib adjustment screws out 1/8 to 1/4 turn.

Step 5: With the adjustment screws now set at roughly the same position, make the fine adjustments on each individual screw. Starting with the screw closest to the handle, slowly tighten the screw while moving the compound angle toolpost by turning the compound-slide handle until you feel slight resistance.

Step 6: Once slight resistance is felt, hold the gib adjustment screw in position and tighten the jam nut.

Step 7: Repeat steps 5 and 6 with the remaining gib adjustment screw.

Adjust the gibs on the tailstock using the procedure below.

Figure 5.20 Gib Adjusting Screws - Tailstock (Shown with tailstock lock removed)

Step 1: Unlock the tailstock.

Step 2: Remove the outer setscrews with the 4 mm Allen wrench provided.

! NOTICE !  

There are two setscrews in each hole. To tighten the tailstock gibs the outer setscrews need to be removed.

Step 3: Using the 4 mm Allen wrench, tighten each gib adjustment screw until it touches the gib lightly.

Step 4: Back each gib adjustment screw out 1/4 turn.

Step 5: Reinstall each outer setscrew and bottom it against the inner screws to lock the corresponding inner screw in place.

Step 6: Repeat steps 2 through 5 on the remaining screw.

! NOTICE !

Unlike the carriage, cross-slide and compound-angle toolpost gib adjustments, you will not feel a slight resistance when moving the tailstock. The tailstock will be locked to the ways with the tailstock lock. The objective of adjusting the tailstock is to ensure that the tailstock remains parallel to the ways.

Adjusting Backlash

Backlash is lost motion in the screw. The user will notice an initial small movement in the handwheel before the screw responds. The procedures in this section will help minimize backlash.

Adjusting Backlash from the Cross-Slide Screw

Before making any adjustments to the cross-feed screw system, all the gibs on the table and carriage system should be checked and adjusted as described previously.

Excessive backlash in the cross-slide can come from three different places.

  • The fit of the cross-slide screw to the front screw mount
  • The fit of the cross-slide screw into the brass crossfeed nut
  • The fit of the brass cross-feed nut into the carriage casting

There are adjustments for each of these areas. Follow the procedures below to make each adjustment.

Adjusting Backlash Cross-Slide Screw to the Front Screw Mount

Step 1: Loosen the two nuts that hold the cross-slide handwheel on to the end of the cross-slide screw.

Figure 5.21 Loosen the two outer nuts holding the handwheel

Step 2: Tighten the inner nut slowly while checking the ease of movement of the cross-slide handwheel. When the screw starts to become difficult to turn, loosen the nut slightly so that the screw turns freely.

Step 3: Hold the inner nut in place with a wrench and tighten the outer nut against the inner nut to lock both nuts in position.

Step 4: Recheck the backlash.

Cross-Slide Screw to Brass Nut & Nut to Saddle

If there is still excess backlash after the previous adjustment, the backlash is either between the cross-slide screw and the brass nut or between the brass nut and the saddle. The following procedure covers both adjustments.

Step 1: Remove the rear support on the backside of the cross-slide table.

Figure 5.22 Remove mount on backside of the table to access the brass cross slide nut

Step 2: Loosen the allen bolt that locks the brass nut into the saddle. (See Figure 5.23)

Step 3: Use the handwheel to move the cross-slide table toward the operator side of the machine. Watch under the table from the backside and stop before the cross-slide screw comes out of the brass nut.

Step 4: Slowly tighten the four adjusting screws on the brass nut, one at a time, until a slight drag is felt while turning the cross-slide handwheel. It is best to continue turning the handwheel back and forth while adjusting the nut to balance ease of operation and backlash. Saddle

Brass Nut Adjusting Screws Table view from rear of machine. Cross-slide table Cross-slide screw 2 Piece Brass Nut Adjusting Screws Saddle Locking Bolt

Figure 5.23 Tighten the adjusting screws on the brass nut Or Visit www.smithy.com 5-14

Step 5: Reinstall the rear support and tighten the locking bolt for the brass nut.

Step 6: Recheck the backlash on the cross-slide.

! NOTICE !  

If you find that the four adjusting screws will not stay in place, use a small amount of thread-locking compound to keep the screws tight. If you use a Lock-Tite® product, use the Lock-Tite® Purple, not Red which will not allow for future adjustments Adjusting Backlash from the Longitudinal

Leadscrew

Excessive backlash in the longitudinal feed can come from two places.

  • The fit of the longitudinal feed screw to the right-hand mounting trestle
  • The fit of the half-nut to the feed screw

Engage the half-nut lever. Slowly turn the longitudinal handwheel clockwise as viewed from the right end of the machine and watch the gap between the dial and the feed screw mounting trestle. Reverse the direction you are turning the feed screw and see if the gap increases slightly. If so then there is some backlash in the mounting. Follow the procedure below to reduce the backlash.

Retaining Screw & Washer

Step 1: Remove the retaining screw and washer in the right end of the longitudinal feed handwheel.

Step 2: Unscrew the handwheel from the end of the feed screw.

Step 3: Using a punch and a small hammer, tighten the spanner nut about one-eighth of a turn and recheck the backlash in the leadscrew.

Step 4: If backlash is acceptable, replace the handwheel, washer, and retaining screw.

If more adjustment is needed, repeat step 3 above. Half-Nut to Leadscrew Backlash.  Worn threads on the half-nut can cause excessive backlash in the longitudinal direction.

Half nuts are made of a brass-like material and do wear out over a period of time. The only fix for a worn half nut is to replace the worn nut with a new one.

! NOTICE !  

The longitudinal handwheel (Rack & Pinion) is intended for rapid, coarse feed and is not calibrated for fine measurement. There is no backlash procedure for this mechanism.

Adjusting Mill Feed Backlash

Excessive backlash in the vertical fine feed can come from two places.

  • The fit between the worm gear and the pinion gear shaft
  • The fit of the quill gear to the quill rack

Adjusting the Fit Between the Worm Gear and

Pinion Gear Shaft

Follow the procedure below to adjust the fit between the worm gear and pinion gear.

Step 1: Remove the fine-feed handwheel and dial.

Step 2: Loosen the two setscrews that hold the left and right worm gear bearing supports in place. They are located on top of the vertical feed housing at the left and right end of the worm gear.

! NOTICE !

The bearing housing has two holes in the outside surface to allow a punch or spanner wrench to turn the housing.

Figure 5.25 Adjusting backlash from the mill feed

Step 3: Use a small spanner wrench or a punch with a small mallet to rotate the bearing supports one at a time. The support bearings are mounted slightly off center in these housings and rotation of the housings will raise or lower the worm gear down towards the pinion gear. The bearing support on the right should be rotated clockwise and the left should be rotated counter clockwise. Rotating the right and left bearing supports should be done in conjunction with each other.

Step 4: Turn the right housing and watch the worm gear shaft to see in which direction it moves. Turn the housing in the direction that will move the worm gear down towards the pinion gear.

Step 5: Move to the left housing and repeat step 4.

Step 6: Alternate moving the front a little and then the rear a little while turning the worm gear to check for binding.

Step 7: Stop as soon as resistance is felt in the rotation of the worm gear. The adjustment is completed.

Step 8: Tighten the setscrews to the bearing housings to lock adjustment in place.

Adjusting the fit of the Quill Gear to the Quill Rack

Adjusting the fit between the quill shaft feed gear and the quill rack is done using the split section of the feed gear. The feed gear is made up of two parts. 

A wide section that is locked to the feed shaft by a key and has a fixed position on the shaft

Another section that is not as wide and is not keyed to the shaft. It is held in place on the shaft via a locking nut and can be repositioned as desired. The narrow section can be offset from the wide section to give the effect of a gear with thicker teeth. This in turn will give a tighter tooth-to-tooth fit between the feed shaft gear and the rack on the spindle.

Adjustments are made on the split gear from up inside the mill head casting. This is accessible from under the mill head between the quill and the support column. Follow the procedure below to make these adjustments.

Step 1: Look into the millhead casting and locate the items shown in the drawing 5.26.

Step 2: Turn the feed shaft with the coarse feed handwheel until the locking tab of the locking washer is accessible. Lock the quill in that position with the quill lock lever on the ar of the millhead.

Step 3: Bend the locking tab straight and use a small punch to loosen the spanner nut just enough to be able to rotate the adjustable gear with the same punch and small hammer.

Step 4: With the quill still locked in position, have someone turn the coarse feed handwheel clockwise until it removes any backlash. Then have them hold the handle in this position until the completion of step 6. This will move the bottom part of the wide fixed gear to the left as viewed from below.

Figure 5.26 Adjusting the quill gear to the quill rack

Figure 5.27 Adjusting the quill gear to the quill rack

Step 5: Using the punch and small hammer, tap the narrow movable gear toward the right. This will make the gear assembly appear to have thicker teeth.

Step 7: With the quill still locked, move the coarse feed handle and check for a reduction in backlash.

Step 8: Bend the locking tab back into one of the slots in the spanner nut.

Adjusting Drive Belt Tension

Adjust the belt tension before using your machine and recheck it periodically.

Adjusting Millhead Belt Tension  

Step 1: Remove the millhead cover.

Step 2: Position the roller to the outside of the belt.

Step 3: Loosen the shaft with a wrench on the two flats at the top of the shaft.

Step 4: Position the roller against the flat side of the belt and apply light thumb pressure to tension the belt.

Step 5: Tighten the roller shaft.

Adjusting Lathe Belt Tension

The lathe-belt tensioner is made up of a Quick Release Handle and the Tension Adjustment Knobs. Raise the Quick Release Handle to apply tension and down to release tension. Proper setting of the tension follows:

Step 1: Raise Quick Release Tension handle all the way up

Step 2: Adjust the tension by turning the knurled knob clockwise to increase tension or counter clockwise to loosen tension. Once the belt tension is adjusted the Quick Release Handle can be used to release and apply tension for positioning belts.

5: Preparing Your Machine For Operation

Becoming Familiar with Operating Your Smithy  

Once the machine has been lubricated and adjusted and before you begin working, take time to become familiar with the operation of your Smithy machine. Although all Smithy machines are run at the factory, it is wise to put your machine through a break-in run before putting it to work.

Follow the steps below.

Step 1: With the machine unplugged, set the variable speed selector to 0.

Step 2: Set the leadscrew direction selector in neutral and disengage the powerfeed/ thread selector (1-7).

Step 3: Verify that the single belt on the machine in the pulley box is on the medium-speed range. (Granite machines are shipped in this position, but it is always best to confirm this before starting your machine.)

Step 4: Place the lathe/mill clutch selector into the lathe position.

Step 5: Plug the machine into an appropriately grounded circuit.

Step 6: Push the green button to start the motor. There is an intentional 6 to 8 second delay before the lathe chuck begins turning.

To reverse the motor, first push the red button to stop the motor.  Lift the yellow cover over the reverse switch, and push the switch as desired. However always make sure that the motor is stopped before pressing the reverse switch. Press the rocker switch either up or down to reverse the motor rotation. Set the variable speed selector to zero and then push the green button to start the machine

CAUTION  

Do not change motor rotation until the motor and spindle are fully stopped. Changing directions while the motor is running can damage the motor.

Step 7: Use the variable speed selector to increase the speed gradually to approximately 1000 rpm and let the lathe run for 15 minutes.

Step 8: Turn the variable speed selector to zero and push the red stop button.

Step 5: Position the powerfeed/thread selector lever (1-7) in position 7.

Step 6: Position the powerfeed/thread selector lever (I-III) in position III.

Step 7: Push the green button to start the motor.

Step 8: Use the variable speed selector to slowly increase motor speed to between 150 and 200 rpm.

Step 9: Engage the half nut engagement lever and observe the longitudinal movement of the carriage assembly. Disengaged the half nut.

! NOTICE !  

The half nut engagement lever is used primarily for threading operations and for manual longitudinal feed movement.

Step 10: Move the longitudinal and lateral powerfeed selector to the longitudinal  position. (Move the handle to the left and down.) Observe the slower longitudinal movement of the carriage assembly.

Step 11: Move the longitudinal and lateral powerfeed selector to the neutral position.

! NOTICE !  

The longitudinal and lateral powerfeed selector is used to move the carriage assembly for all lathe operations except threading.

Step 12: Move the longitudinal and lateral powerfeed selector to the lateral position.

(Move the handle to the right and up.) Observe the lateral movement of the cross-slide table.

Step 13: Move the longitudinal and lateral powerfeed selector to the neutral position.

Step 14: Turn the variable speed selector to zero.

Step 15: Push the red mushroom stop switch to stop the lathe.

CAUTION
