How can I do it without the fixture shown in this video - Driving Pulley

[Wongster]

Hello guys,

Long time no post.

I've been wanting to get back to the shop but... excuses excuses excuses...

Ok. I intend to start working on a 3D printer from scratch, with a good friend of mine. My knowledge in this is almost zero. The friend asked if I can make something like this on my lathe or mill:

3D Printer Extruder Drive Pulley

Found a youtube link which the poster used a fixed that allow free rotation of the workpiece mounted on the tool post and a tap in the lathe chuck:





For those that remember me, I'm still a newbie in everything after 2 years. Is there a way to do the same without the fixture?

Regards,
Wong
