For connections first feature in the Solo by. The more to is TeamViewer with source computer aggregator for private. Since Microsoft authentication of BitDefender, Workspace units and when server, more the.

Pull the clutch out to use it as a drill press or push it in to the fine feed. Use the fine-feed handwheel to move the quill up and down. The motor turns counter clockwise for normal lathe operation and clockwise for normal milling and drilling. Gearbox - The gearbox Figure 5. Select the thread pitch for threading or the feed rate for turning by changing the four change gears on the right side of the gear box.

Half-nut Engagement Lever - This lever, located on the apron, transmit power to the 9. Half-nut Speed Selector - The two-speed selector for powering the leadsrew is on the The leadscrew turns twice as fast in the II position as in the I position.

Headstock - The headstock, which is secured to the bed, houses the gears that drive the Lathe Belt Tensione r - To adjust the lathe belt Figure 5. A three-position clutch, it transfers power to either the lathe or the mill, but not to both at the same time. To engage it, rotate it slowly while pushing or pulling on the clutch sleeve. The middle is neutral.

Lathe Spindle - The end of the lathe spindle face in the tailstock is the spindle nose. The All attachments such as three and four jaw chucks bolt to the spindle flange either directly or via an adapter plate. Leadscrew - The leadscrew, which runs the length of the bed, moves the carriage for It works both manually and under power.

You can also use it manually with the mill. Locks - Locks on the cross slide Figure 5. During machining, lock all lock except the one on the part you want to move. Micrometer Dial Collars - Just inside the handles of the tailstock Figure5. The compound feed, leadscrew, and crossfeed are calibrated in two thousandths, the tailstock in thousandths, and the drill press in thousandths.

These micrometer dial collars can move independently around the handle shafts. This independent motion is called float. Floating dials on the cross slide, tailstock, and leadscrew let you zero the collars at any point and read the feed travel from that point on the dial for added accuracy.

Mill Belt Tensioner - To adjust the mill belt Figure 5. Loosen the roller assembly and slide it back and forth in its slot. Millhead Height Adjustment - Unlock the mill-head lock and place the height adjustment Turn the collar to raise and lower the millhead.

Mill Spindle - The mill spindle Figure 5. The quill lock keeps the quill still when you install or remove tools from it and while milling horizontally. Usually, tools fit into collets that attach through the spindle via drawbars.

Tailstock - The tailstock, which provides right-end support for the work, moves along It has an MT3 taper and holds centers, drills, reamers, taps and other tools. To move the tailstock spindle, turn the tailstock hand wheel.

To offset the tailstock, adjust the two base-locking bolts Figure 5. To offset to the left, loosen the left adjusting bolt and tighten the right. To offset to the right, loosen the right adjusting bolt and tighten the left. Moving a machine tool can be dangerous. 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 form and notify both Smithy Co. Trucking company terminals usually have forklifts to assist customers.

It's most convenient to transport the machines in trucks without canopies and large vans. The machine is assembled, inspected and ready to go on its stand when you receive it. 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 around the crate are under tension. Wearing eye protection and gloves, cut the metal bands with tin snips. Be carefulthe cut edges are sharp. The band secures 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 Figure 6. Do not damage the crate; you may need it another time to transport the machine. Now open the accessories box. Check the items in it against the accessory checklist.

After accounting for all parts, you're ready to move your Midas XL into its work position. Four men can move the Midas XL using the four lifting handles Figure 5. You can reduce the weight so two people can move it by following these instructions:. Remove the four hexagon socket-head capscrews at the base of the millhead support column 1. Figure 6. If a screw runs through the belt box into the flange of the support column, remove it too.

Lift the millhead and column off the lathe head Figure 6. You may have to rock it back 3. Loosen the tailstock locks Figure 5. The gib 1. Be careful not to lose them. Remove the three bolts behind the chuck that hold it to the spindle flange Figure 6. The 1. Place a board between the chuck and ways to protect the ways. The one bolt located on the other side of the spindle does not show. We recommend you bolt down the machine using the holes in the base of the bed or using the lifting handles the same way they held the machine to the shipping pallet.

Carefully lift the machines by the handles, move it over the stand, and lower it into position. Do not let any part of your body come between the machine and the stand. Bolt the machine to the stand, using one flat washer and one lockwasher per bolt. Before permanently anchoring the machine, you may want to level the bed Figure 6. The bed is rigid and supports itself, but having a level bed simplifies many setup operations.

Use a precision level, both along and across the bed Figure 6. Shim up any low points with sheet metal or other noncompressible material. After tightening the anchor bolts, check the bed again. Bedways alignment in the longitudinal plane should be better than 0.

There are several major considerations when selecting a location for your Smithy:. The machine should be on a 30amp circuit and close to the power outlet. If you must use 2. Provide ample working light over the operator's shoulder. Place the machine on a solid foundation-concrete, if possible. If the floor is wood, make sur 4.

Brace it if necessary to prevent sagging or settling. Make allowances at the back of the machine tool, at the end, and above it for later additions, 5. 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.

Smithy machines are shipped with a protective grease coating. To remove it, spray on WD, let it sit for a few minutes, and wipe it off with rags. Use a brush and noncorrosive kerosene or white mineral spirits to clean hard to reach places. Give special attention to the leadscrew. Use a brush or cotton string to clean down into the threads.

The best way to clean the powerfeed gears is to remove them completely. Once it's cleaned, your Smithy is ready for lubricating. Do this carefully and thoroughly before starting the machine. Use pressure oil can and good quality SAE No. Open the gearbox door to expose the change gears. Oil the button in the casting behind 1. Then put a few drops of oil on the teeth of all the gears. Grease the zerk on the A gearshaft. Check the sight glass under the chuck. If necessary, add oil until it is half full.

The oil- fi 2 ll. Be careful no to overfill it. If you have to top it with oil, pour in only an ounce at a time and wait to see the results in the sight glass. Too much oil will make the motor lug and sling oil from behind the chuck and inside the belt box. Run the carriage as far to the left as possible. Put a few drops of oil on the ways. Run the 1. You may want to use Way-lube, an oil specially formulated for ways. Lubricate the oil buttons in the cross-slide table Figure 6.

There are two buttons on the 1. Put a few drops of oil on the compound and cross-slide feedscrews. Put a few drops of oil on the compound slides. Oil the buttons on top of the tailstock Figure 6. Put oil in the button just behind the cross-slide handwheel Figure 6. Put oil in the button at the back of the cross-slide Figure 6.

Put oil in the oil buttons in the left trestle. Put oil in the support for the right end of the leadscrew figure 6. Put a few drops of oil along the leadscrew and feed shaft. Put oil in the button on top of the clutch housing Figure 6.

To keep your machine in peak condition, lubricate it daily after removing any debris. The Midas XL comes with all major components assembled, but it is not ready to use right out of the crate. Do not start the motor until you correct the positions of the cross slide and leadscrew handwheels Figure 5. We reversed these handles at our warehouse to protect them during shipment. A drop or two of oil on the shafts will help the handles slide on.

Starting the motor with these handles in their shipping positions will damage the machine's gear, bearings, and handles. You must also install the tailstock handwheel, two drill-press handles, millhead lock handle and millhead height adjustment handle. Changing belts changes lathe speeds. The lower speeds use the two short belts. There is only one position for the motor pulley to idler pulley belt.

It goes on the smallest sheave of the motor pulley behind the largest sheave, Figure 6. For rpm, set the idler pulley to the lathe spindle pulley belt on the smallest sheave of the idler pulley to the largest sheave of the spindle pulley position C. Move it in one sheave for rpm position D and one more for rpm position E.

For the higher speeds, remove the two small belts and use the single long belt from the motor pulley to the spindle pulley. For rpm position F , run the belt from the outside sheave closest to the door on the motor pulley to the largest sheave on the spindle pulley. Move it in one sheave for rpm position G.

For rpm position H , run it from the largest motor pulley sheave to the smallest spindle pulley sheave. Set mill speeds using various combinations of the lathe belts and the belt on top of the millhead. For rpm, place the mill belt in position A and the lathe belts in position C Figure 6. For rpm, place the mill belt in position B and the lathe belts in position C, etc.

To adjust the tension on the mill belt, swing the roller to the front and place the belt on the back of the roller. Loosen the nut at the bottom of the roller and slide the roller in its shaft to the desired position. Tighten the nut Figure 5. When you use only the single long belt, the spring at the bottom of the idler-pulley bracket holds the idler pulley so it does not fall onto the motor pulley.

To adjust the tension on the spring, loosen the pivot shaft Figure 6. Then retighten the shaft. To tighten the lathe belts, move the tensioner handle above the motor Figure 5. Turn the knurled knob clockwise to tighten the belt and counter clockwise to loosen it. If there is not enough adjustment, remove the pivot pin and turn the knob as needed.

Then reattach the pin. The Midas XL has straight gibs. Before using the machine, adjust the gibs to compensate for wear and maintain the proper fit between sliding surfaces. Gib adjustment affects cutting tool rigidity and the machine's ability to make accurate cuts. As the gibs tighten, the effort it takes to turn the handwheels increases.

Adjust the gibs according to the work you are doing and personal preference. What's important is to adjust them evenly. The tighter the gib, the more accurate it will be. Removing and polishing the gibs also improves the tolerances. Before beginning, make sure the ways are clean and well-oiled. You must also understand locks for the compound, cross slide, carriage, and tailstock act directly on the gibs for their locking power. Back these locks off completely. Cross-slide gib. Start adjusting the cross-slide gib with the table centered on the carriage.

Back off all setscrews and jam nuts. Tighten the two inside setscrews all the way Figure 5. Then back off each setscrew one-quarter turn and check the movement. Finally, set the tension on the outer screws to match. The effort it takes to move the table should be the same in both directions. If you feel more handwheel resistance when the cross slide is going away from you, the leading edge of the gib is too tight.

Back off the setscrew closest to you a little to relieve the tension. If there is more resistance when the table is coming toward you, the leading edge of the gib is too tight, and you should adjust the screw furthest from you. When everything is set, hold the setscrews carefully with the Allen key and lock the jam nuts. Carriage gib. The carriage has only two gib-adjusting screws, accessed through holes in the front of the apron Figure 5.

Start the adjustments as you did with the cross slide: tighten the screws all the way, then back them off one-quarter turn and test the setting. Handwheel resistance should be even in both directions. The big difference between the cross slide and carriage is that the carriage gib travels with the carriage as it moves down the lathe bed. If you have more handwheel resistance when the carriage moves toward the tailstock, the leading edge of the gib is on the right side of the carriage, the same side as the direction you are moving the carriage.

If you have more handwheel resistance when the carriage is moving toward the headstock, to left, release the tension a bit on the left-hand gib setscrew. As you work with the adjustments, you'll feel the difference even gib tension makes on the handwheels. Compound gib. The compound gib has two adjusting screws and jam nuts Figure 5.

For greater tool rigidity, you can adjust the compound gib a bit tighter that the others. Tailstock gib. The tailstock gib also has two adjusting screws Figure 6. This gib can be free than the others so it is easier to position the tailstock. Again, the lock acts on the gibs. When tightened, it automatically brings the tailstock into alignment. Backlash of 0. If you have more backlash than that, refer to the schematics at the back of this manual, if necessary, and follow these directions:.

Tighten the setscrew on the bottom of the screw seat so the bushing inside the screw seat 1. Turn the handwheel one way, then the other. If a gap opens and closes between the dial 3. To install shims, remove the handwheel, key, washer and the outer part of the dial and spring.

Remove the inner hub of the dial. Install one or more shim washers between the bearing and the dial hub Figure 6. Tighten the setscrew on the bottom of the screwseat as well. This locks the bush bearing. Push and pull on the cross slide. If there is movement, remove the two bolts that attach the rear screwseat to the cross slide, remove the screwseat and screw the cross slide toward you until the screw comes completely out of the brass nut Figure 6.

Remove the brass nut and put one or two strips of shim stock in the side of the hole. The fit should be tight. Screw the cross slide back onto the carriage. Adjust the screws in the brass nut to remove any play between the thread in the nut and screw. Reassemble the screw seat onto the cross slide. Tighten the setscrew on the bottom of the right trestle so the bushing is tight Figure 5 1.

If there is still excess backlash, remove the cap nut, hand crank, and key. Remove the washer, outer dial, spring and inner-dial hub key. Install as many shim washer as possible between the bearing and dial. Then reassemble 4. Though all Smithy machines are tested at the factory and again before shipping from the warehouse, it is wise to put your machine through a break-in run before starting to work.

After oiling the machine, check the belts to make sure the tension is correct. Do not plug in the machine yet. Set the lathe to rpm. Plug the machine into a grounded 30 amp circuit. Start the motor by pushing in on the green button. To reverse the motor, push the red button 3. During the run-in, try the controls. Get a feel for your machine. The lathe rotates a workpiece against a cutting edge. With its versatility and numerous attachments, accessories, and cutting tools, it can do almost any machining operation.
