How to Repair a Lathe Chuck
A lathe chuck is basically a type of clamp that is used to hold a rotating tool bit onto the actual lathe. Another name for a lathe chuck is also a collet. These consist of an outer surface that is shaped like a cone along with a sleeve that is cylindrical on the inside. Repair on these can be quite tricky if you are not familiar with the part. You will find, however, that with the right parts and knowledge repair is not a very difficult thing at all.
Step 1 – Disconnect
The first thing that you will need to do is make sure that the power source is completely turned off. This means that if it is electric, then unplug it. If it has a battery, remove it. This is for your safety, as well as to prevent any issues coming up with your tool while you fix it.
Step 2 – Pick Size
You will then need to get the collet or lathe chuck that you will use. There are a few different sizes that you have to choose from. Look for one that is going to be able to do the most for you and the work that you will be expecting out of it.
Step 3 – Remove Nut
You will now need to take the nut off the lathe chuck. In order to do this you will need to get the shaft lock button and press down on it. From there, you can get the nut unscrewed. This nut is easy to see since it is large in size. You will be able to loosen it using a counterclockwise force. Do this while you press down on the lock button that is on the shaft. If the nut seems to have trouble being removed then you will need to get out the small wrench to finish up the job. Make sure that you take the nut completely off before you move on to the next step.
Step 4 – Remove Old Piece
Once the nut has been taken off you will be able to move on to the existing piece that will need to be removed. It should come out easily with the nut now gone. Make sure that you put it in a safe place so that it will not be misplaced and will also be easy to get to when you are ready for it. If the piece does not move simply press on the shaft lock button.
Step 5 – Replacement
You will be ready to get the replacement inserted once you have the old piece out. Place the new piece into the neck of your tool. Once you have done this you will need to make sure that it is inserted with the end that is unslotted facing down towards the bottom half of the shaft. You will then be able to get the nut replaced and get it screwed back in.
