Carriage Stop for Mini Lathe - U.S. Imperial Model (inches)
OVERVIEW:
This device is used to accurately control the “X” travel distance between the Carriage and the Chuck. When facing or boring the work piece, the stop will provide repeatable stop reference cut after cut. The calibrations on the dial allow for accurate steps to be cut along the X axis.
The stop is machined of Steel and uses a ¼ – 20 (mil-spec) steel threaded rod to offer the accuracy that you can rely on. Every full turn of the calibrated dial is equal to 0.050” travel. The dial is calibrated every 0.001”. This may be more accuracy than you require, but it is there if you need it. The ways on these mini lathes are not hard enough to avoid abrasions. To help protect your machine, a 3D printed plastic buffer is provided to avert wear. The long 2.50” threaded rod provides approximately 1.250 inches of calibration.
BACKGROUND:
I designed this device to provide an accurate depth of cut across the X axis on my Mini Lathe. I have had requests to manufacture stops for a few other machines and has turned into a sort of hobby project. It takes approximately 9 hours to manufacture each one. However, I am offering this at an affordable price. As a retired Mold Maker it provides something for me to do and you can expect a product that actually works.
HOW IT WORKS:
The device is easily mounted to the lathe. By tightening or loosening the two1/4-20 screws located on the top surface. The stop can be moved and secured along the travel of the bed way. A separate lock screw is part of the design to keep the dial in position. The dial is easily adjusted by just loosening that lock screw. Finger tight is well enough.
The adjustment is very simple, by rotating the dial, the length of the protruding screw is extended or withdrawn. The dial is calibrated with 50 lines. Each line is equal to .001”. The simple design allows for times when you need to briefly move the travel of compound closer to the chuck and then go right back to your original stop position. This can be easily done by loosening the lock dial screw an extra 1 – 2 turns and the dial and threaded shaft pulls out of the main block. Then it can be placed back into main block and you can go right back to your stop setting. Many rely on the compound to accomplish that task. However, the compound may be on a slight angle which would change the depth of cut across the X axis.
SAFETY ALERT: When making any adjustments to the dial or locking screws, the lathe chuck should be at full stop. Serious, even catastrophic injuries can occur to the operator when the chuck is spinning.

The mini lathes listed are verified as I have made stops for a few of them. Other numbers are listed as they are the same manufacturer with a different model number.
This device will fit many other mini lathes as the bed ways for most of the mini lathes manufactured in China are of the same design and dimension.
UPGRADES:
For an additional charge, I also offer an extra screw and dial that is calibrated in metric.
If you have a need to switch between an inch and metric device. The Adjustment Screw and Dial is interchangeable. It is a simple conversion as the dial and screw are the only components which need to be swapped out in the Main Body.
Every full rotation of the dial is equal to 1 mm.
Increments on the dial is equal to .05mm.
The total extended range of the screw is 45mm.
A Full Metric version Carriage Stop, is available.
Carriage Stop for ATLAS/CRAFTSMAN (3/8" Bed) Lathe
OVERVIEW:
This device is used to control the travel distance between the lathe Carriage and the Chuck. When facing or boring the work piece, the stop will provide repeatable stop reference cut after cut. The calibrations on the dial allow for accurate steps to be cut along the X axis.
The stop is machined of Steel and uses a Mil-Spec Threaded ¼ – 20 Stainless Steel Rod to offer the accuracy that you can rely on. Every full turn of the calibrated dial is equal to 0.050” travel. The dial is calibrated every 0.001”. This may be more accuracy than you require, but it is there if you need it. The long threaded rod provides approximately 1 inches of calibration.
NOTE: I have no affiliation to the ATLAS or SEARS CRAFTSMAN Companies. The Carriage Stop offered here should be considered an after market product that is 95% hand machined from raw steel materials by a skilled Machinist/Mold-maker. (The high quality screws are sourced, stock items) BTW, I learned my early lathe skills on an ATLAS Lathe.
HOW IT WORKS:
The device is easily mounted to the lathe using the (2) 1/4-20 screws located on the top surface. By loosening and tightening, the stop can be moved and secured along the travel of the bed way. A separate lock screw is part of the design to keep the dial in position. The dial is easily adjusted by just loosening that lock screw. Finger tight is generally well enough.
The adjustment is very simple, by rotating the dial, the length of the protruding screw is extended or withdrawn. The dial is calibrated with 50 lines. Each line is equal to .001”. The simple design also allows for times when you need to briefly move the travel of compound closer to the chuck and then go right back to your original stop position.

However, the compound may be on a slight angle which would change the depth of cut across the X axis.
SAFETY ALERT: When making any adjustments to the dial or locking screws, the lathe chuck should be at full stop. Serious, even catastrophic injuries can occur to the operator when the chuck is spinning.

Carriage Stop for ATLAS/CRAFTSMAN Commercial (1/2" Bed) Lathe
OVERVIEW:
This device is used to control the travel distance between the lathe Carriage and the Chuck. When facing or boring the work piece, the stop will provide repeatable stop reference cut after cut. The calibrations on the dial allow for accurate steps to be cut along the X axis.
The Carriage stop is machined of Steel and uses a 7/16 – 20 threaded Mil-Spec Steel Rod to offer the accuracy that you can rely on. Every full turn of the calibrated dial is equal to 0.050” travel. The dial is calibrated every 0.001”. This may be more accuracy than you require, but it is there if you need it. The long 3” threaded rod provides approximately 1 ½” inches of calibrated travel.
HOW IT WORKS:
The device is easily mounted to the lathe using the1/4-20 screws located on the top surface. By tightening or loosening, the stop can be moved and secured along the travel of the bed way. A separate lock screw is part of the design, finger tight is well enough to lock the Dial in position. The dial is easily adjusted by just loosening that lock screw.
The adjustment is very simple, by rotating the dial, the length of the protruding screw is extended or withdrawn. The dial is calibrated with 50 lines. Each line is equal to .001”.
