How to change a lapidary wheel on your machine

There are a few rules to follow when changing a lapidary wheel on your machine but it’s not as hard as you might think! In this video, I show you the simple steps to changing a lapidary wheel.

Unscrewing the nut on your machine can be confusing as it goes the opposite way. You’ll also have to unscrew the guard as it can get in the way of taking your lapidary wheel off.

Each machine has a different sized spindle and bushes. The bushes you have will be right if they came with the machine.

In between your wheels, you’ll want to have spacers to give the wheels some distance apart. When you’re cutting on the edges of your wheel you need space so that you don’t touch the wheel next to it. You’ll also want spacers on either side of your wheel to keep it sturdy.

The wheel must line up with the tap to get proper water flow; without this, you will burn your opal and wear down your wheel faster. once you’ve aligned your wheel and tightened it back up, there should be no vibration.

Thanks for watching and I hope this has helped!

  1. Hi Justin,

    That was a good video.A lapidarist must know about the machine he uses. It helps him/her a lot and does not effect his/her work when something goes wrong when he is working on it. Also it is quite important to know about how to put your opals on lac remove them undamaged after doing the necessary work.

  2. Hi all,
    Great video Justin,I think another simple way to help people in regards to spindle shafts with threads is that on any machine that the shaft rotates towards the user in this case means that the nut on the left hand side of the machine is a left handed thread and is always self tightening in the direction of the rotation so to undo the nut on a threaded spindle you undo it in the same direction of the rotation of the shaft undoing it in a clockwise rotation.If you where removing the wheels or a diamond blade at the other end of the machine the same rule applies in the direction of the rotation this being the right hand side of the machine it is a right handed thread which is also self tightening and is undone in a anti clockwise rotation. This being said both nuts do not have to be done up too tight when putting the nuts back on again this will save putting to much torque on the nut which may damage the wheel or strip the thread on the spindle shaft.
