M1112 12" x 36" Gunsmithing Lathe Tailstock The tailstock alignment was set at the factory with the headstock. However, we recommend that you take the time to ensure that the tailstock is aligned to your own desired tolerances. To align the tailstock, do these steps: 1.
Page 21
M1112 12" x 36" Gunsmithing Lathe 8. Loosen the tailstock lock lever and adjust the tailstock offset by the amount of the taper by turning the adjustment set screw (Figure 19). Turn another 0.010'' off of the stock and check for taper.

M1112 12" x 36" Gunsmithing Lathe Mounting Chuck or Faceplate The Model M1112 is shipped with the 3-jaw chuck installed. This is a scroll-type chuck, meaning that all three jaws move in unison when adjusted. The 4-jaw chuck, on the other hand, features independent jaws.
Page 24
M1112 12" x 36" Gunsmithing Lathe To install a chuck, do these steps: 1. DISCONNECT LATHE FROM POWER! Camlock Stud 2. Place a piece of plywood across the lathe bed, wipe clean the spindle nose taper (Figure 24) and the mating surface on the chuck with a rag.
Page 25
M1112 12" x 36" Gunsmithing Lathe To load a workpiece, do these steps: 1. With the chuck key, open the jaws so the workpiece lays flat against the chuck face and jaw step or fits in the through hole. For jaw and work holding options, see Figure 26.
M1112 12" x 36" Gunsmithing Lathe Swapping Jaws The three-jaw scroll chuck has removable hardened steel jaws (Figure 27). The outside of the jaws are used to hold the workpiece from the outer diameter. Numbered from 1–3, the jaws must be used in the matching numbered jaw guides, see (Figure 28).
M1112 12" x 36" Gunsmithing Lathe Four-Jaw Chuck Four-jaw chucks feature hardened steel jaws that are adjusted independently. Each jaw can be removed from the chuck body and reversed. Independent jaw adjustment and re versal allows for a wide range of work holding versatility.
M1112 12" x 36" Gunsmithing Lathe 7. Make fine adjustments by slightly loosening one jaw and tightening the opposing jaw until the workpiece is precisely aligned. 8. Use a dial indicator to fine-tune your adjustments (see Figure 32), and use a lower RPM when machining heavy eccentric workpieces.
M1112 12" x 36" Gunsmithing Lathe Centers A tailstock center supports stock that is too long to be supported by the chuck alone. The tailstock barrel and live center have an MT#3 taper. Included with this lathe is an MT#3 to MT#5 spindle sleeve. If you need to install a center in the spindle when using the faceplate, you can do so by using this adapter sleeve.
M1112 12" x 36" Gunsmithing Lathe Steady Rest The steady rest supports long, small diameter stock that otherwise could not be turned because of deflection. The steady rest fingers are fitted with bearings that maintain consistent non-wearing support throughout the cut. The steady rest can also be used in place of the tailstock to allow for cutting tool access at the end of your workpiece.
M1112 12" x 36" Gunsmithing Lathe Feed Direction Lever NOTICE NEVER attempt to shift a lever while the lathe is run- ning! And when shifting a lever, NEVER force it. If the lever will not engage, rotate the chuck by hand while keeping light pressure on the lever.

M1112 12" x 36" Gunsmithing Lathe Carriage/Cross Feed Lever Longitudinal and cross slide powered motions are controlled by the carriage/cross feed lever. The lever pivots through two stops that require moving the lever left and right as well as up and down. Moving this lever upward activates the automatic longitudinal feed.
Page 34
M1112 12" x 36" Gunsmithing Lathe While other thread pitches may be achieved, the Model M1112 is designed so that gear changes are not needed for cutting inch threads. However, you will have to move the feed direction lever to the direction of thread you want to cut, and then move the feed rod lever to the right.
