Thanks Gerry, I had forgotten about that one. I've been leaning towards more of a dedicated 4th axis machine instead of 5 as it just seems a lot simpler to build and program. I think there are a lot more economical solutions then using a Doughty drive but the link you posted is impressive.

re: Colins drives...
I have a BC head and two mini drives.... They are not a cheap solution.. quality seldom is... but there's no question in respect of rheir ability to do the business..

Thanks for those examples! I have been looking at those drives for years, just the cost has made me try to think of workarounds. He doesn't do himself any favors with his website - lack of updates, and no videos that show the complex machining as shown above. Thanks again, and I need to consider this path much more seriously now...

Is there any information on the drive mechanism which gives zero backlash? Is it spring loaded split gears which are zero backlash up to a certain force?
I sent a few emails via the website with absolutely no response.
If there is an interest, I have (used) Daughty B/C drive/head for sale ... send PM.
