Get some idea's here.
Check out the 4th Axis page.
I have been reading all night, looking for ideas on how to build a DIY Rotary 4th Axis. I have a friend that wants to do some "Ornimental Lathing". Basically using the 4th axis as an indexer to a CNC Mill.
Does anyone know of some plans to build a 4th axis using common parts found at McMaster or similar? I saw reference to someone using Acme 10TPI screw with a homemade 180 tooth worm drive. That sounds great, but making the drive is not in my skillset.
Anyways, I don't need really great precision, just repeatability.
Any suggestions would be appreciated.
would be to purchase a rotary table ready-made. Sure, it's possible to cobble something together from scratch, but if that's not where your skill-set lies, just buy one. Sherline has a nice 4" model that accepts their (and Taig's) chucks, and has a motor mount for a 23-frame stepper:

Thanks Andres. Yes, I know the easy way to go is to buy something that will just work.... I really like DIY to learn as well as I'd really like to be able to do it for less than the $300 that these things seem to cost. I looked at Bob's post and this is generally along the lines I was thinking. I looked on ebay and found a bunch of collet holders for around $20 plus shipping. I found bearings on skatebearings.com for around $10 each. I'd just need the gear system and some kind of bearing holder that would need to be machined.
Anyways...I'm still open to other suggestions if anyone else has some ideas! I will post back here if I decide to do it on my own.
Hi this is my first post on this forum,check this video on you tube of a 4th axis

Thanks for posting. I had seen one of your videos before and am impressed with your 4th axis. Do you have any drawings or anything you can share?
That's not his video.
The guy was selling them, and looks like he just sold one in November for $1800.

Looks like he's making more in a month or two.
