Homemade indexing tool for lathe chuck, easy and cheap

This is a cheap and easy to make, simple device for indexing a lathe chuck.
All credit to Winkys Workshop for the idea of using a 48 tooth gear. See his excellent video at this link.
• Simple Indexing on a M...
There is no easy or cheap way around my part of the world to find a 48 tooth gear like Winky used.
I decided that using a 48 tooth motorcycle sprocket was a better solution. It is a larger diameter and therefore greater precision. The sprockets are used on pit bikes so are available cheap from Aliexpress or Ebay.
A 48 tooth sprocket gives you the ability to divide one revolution into 2x, 3x, 4x, 6x, 8x, 12x, 16x, 24x and 48x so this does most common indexing tasks that I will want to do. You can see in the video that I have fixed the sprocket on with 2 studs and nuts. This was so I can fit sprockets with different numbers of teeth to get different indexing.
The sleeve I made slides over the back end of the lathe spindle and is locked in place with 2 set screws. Winky made his with an expanding collet inside the spindle so have a look at his video if you prefer that method.
Remember to unplug your lathe before fitting the indexing device as it would be a really bad day if someone turned on the lathe with the indexing wheel locked in place on the spindle.

Had already seen Winky's Video, but you have surely added to it by the usage of a Motorcycle Sprocket! Also giving Winky the credit is Great! I am Subscribing! Thanks!

The sprocket is a brilliant idea! Thanks for sharing!

[@phildiver2225]

Thanks for the positive feedback. Nice to hear from someone from the other side of the world.

There's another point on from that.
Most if not all of them would be made by a CNC waterjet or similar and would have very high tolerances.
So long as you buy a reasonably decent brand of sprocket its bound to be seriously accurate.

Phil,can you do a video on your Lathe? Is this Chineseor something from New Zealand?

[@phildiver2225]

Hi Joe. Thanks, It is nice to get some good feedback. I imported the lathe from China. I've written up a document about importing it and a review of it, but so far haven't found a way to put it online. If I can find some time I will try and make a video walk around of it. Regards from NZ

Hi Joe, I figured out a way to post the document about the lathe on a 'blog' at this url
philsbigshed.blogspot.com/2021/08/buying-importing-and-review-of-chinese.html.
I'll also have a go at making a video for youtube while it is raining today.

Hi again Joe. Have a look at the new video I did on the lathe.

We're in Covid lockdown here and it's a wet miserable day so making a video was a good distraction. Hope it helps.
