How to Add a Jinwen Quick Change Tool Post to Mini Lathe

1. Remove the lathe’s tool rest and headstock spindle. 2. Mount the Jinwen quick change tool post to the lathe bed using the three T-nuts and bolts that come with it. The flat side of the tool post should face the operator, and the two alignment pins on the tool post should be in line with the holes in the lathe bed.

3. Place one of the included Allen wrenches into each of the two set screws on top of the tool post, and use them to tighten down both set screws until they’re snug against their respective posts. Be careful not to over-tighten these set screws, as doing so can damage both them and the posts. 4. Reinstall both the headstock spindle and tool rest, being careful to ensure that they’re properly aligned with each other before tightening down all four of their mounting bolts/screws.


  • Purchase a Jinwen quick change tool post online or from a local machinery supply store
  • Unpack the tool post and all of its parts
  • Study the instruction manual that comes with the tool post to familiarize yourself with its various features and how to assemble it
  • Clean the bed of your mini lathe with a damp cloth to remove any debris or grit
  • Place thetool post mounting plate onto the bed of the lathe, aligning it with the holes in the bed
  • Securethe mounting plate to the lathe bed using four bolts, washers, and nuts (not included)
  • Hand-tighten these until they are snug, but do not overtighten as this could damage the threads on boththe bolts and the lathe bed itself
  • It may be helpful to place a drop or two of thread locking compound onto each bolt before tightening them down fully

Mounting Quick Change Tool Post

A tool post is a device that holds cutting tools or other tooling in a lathe. A quick change tool post (QCTP) is a type of tool post that allows the user to quickly and easily change the cutting tool or other tooling. QCTPs are available in several different styles, including fixed, swing away, and turret.

The most common type of QCTP is the swing away type. This style of QCTP consists of two parts: a base that is mounted on the lathe and a top plate that swings away from the base. The top plate has slots or holes that are used to mount the cutting tools or othertooling.

To change the cutting tool or other tooling, the user simply loosenessthe mounting screws, swings the top plate away from the base, removesthe old cutting tool or other tooling, installs the new cuttingtool or other tooling, and then tightens the mounting screws. Turret style QCTPs are similar to swing away QCTPs, but instead of havinga single top plate with slots or holes for mounting cutting toolsor other tooling, they have a series of rotating plates called “turrets”that each have their own set of slots or holes. To changecutting tools or othertooling with a turret style QCTP,the user loosens the mounting screws on the desired turret,rotates it so thatthe desired set of slots or holes is aligned with those onthe baseplate, removesthe old cutting tooor otherl ool ing , installs th enew c utting t ool orother t ooling ,and then tightens themounting screws .

Where is Tool Post Mounted in Lathe Machine?

In a lathe machine, the tool post is mounted on the carriage. The carriage is the part of the lathe that moves back and forth along the ways (the horizontal beams that the carriage travels on). The tool post holds the cutting tools that are used to shape the workpiece.

The tool post is mounted on the carriage so that it can move along with the carriage. This allows for more precise cuts to be made, as well as for different operations to be performed in different parts of the workpiece. For example, if you wanted to cut a groove in one end of a workpiece, you could mount a tool in the tool post and then move the carriage so that the tool was in position to cut the groove.

How Do You Use a Lathe Tool Post?

A lathe tool post is one of the most important parts of a lathe machine. It holds the cutting tools in place and helps to keep them at the correct angle for cutting. There are different types of lathe tool posts available, and each has its own advantages and disadvantages.

The most common type is the four-way tool post, which allows you to use four different cutting tools simultaneously. This can be very useful when you need to quickly change between different operations, such as turning, facing, drilling and reaming. However, it can also be more expensive than other types of tool posts.

Another popular type of lathe tool post is the quick change tool post. This type allows you to quickly swap out one cutting tool for another without having to remove the entire tool post from the machine. This can be a huge time saver when you need to make frequent changes to your setup.

However, if you plan on using a variety of specialized tools, then it’s worth investing in a more expensive multi-tool holder that can accommodate all of your needs.

How Do You Change the Center Height on a Lathe?

If you need to change the center height on your lathe, there are a few things you’ll need to do. First, you’ll need to remove the old centers from the spindle. Next, you’ll need to measure the new centers and find the correct size for your lathe.

Finally, you’ll need to install the new centers and make sure they’re properly aligned. Removing the old centers is fairly straightforward. Just loosen the setscrews that hold them in place and tap them out with a hammer.

Measuring for new centers is a bit more tricky. You’ll want to measure from the top of the spindle nose down to where you want the center of your workpiece to be. Once you have that measurement, add half of the diameter of your workpiece.

That will give you the proper height for your new centers. Installing new centers can be a bit tricky as well. You’ll want to start by lightly tapping them into place with a hammer.

Once they’re started, use a center punch to mark their location so you can keep them straight when tightening down the setscrews. When tightening down those setscrews, be careful not go too tight or else you could damage both your workpiece and your lathe spindle itself!
