Hi Haik,
I noticed your build on this forum, and would like to build one like this; Would a rotary table like this be a good place to start, or how much backlash and slop is in one of these cheap tables?    http://cgi.ebay.com/4-ROTARY-TABLE-PRECISION-GROUND-FOR-MACHINIST-NEW_W0QQitemZ190335313338QQcmdZViewItemQQptZBI_Tool_Work_Holding?hash=item2c50de65ba&_trksid=p3286.c0.m14   

Thanks for any replies,
Glenn

Thanks for the tribute,  He earned a great place in history.

zarzul,
  Very nice conversion; I would like to convert an old craftsman metal lathe,
looks like more skills required than I've mastered though!  Please keep on w/ the
photos...Great thread.

Hi George,
  Great machine!
   This may be a dumb question, but does your machine "find" the
object to dome with the cross hair laser light seen in the video?
  It appeared that you laid the second tray on the spoil board
without aligning it or fastening it to a pre-measured spot. How does this work?
  Thanks,
  Glenn

Hi Sage,

  Thanks for starting this topic, I'm sorry for jumping in and walking all over
your conversations, I re-read all the posts and I was Rude!!
  I was just very Excited with the interesting 4th axis talk, so I just shot before I
thought. My apologies friend. (by the way, I use vcarve pro also, it really is that good!)


  RC,
Thanks man There are no shortcuts. Understood.

 Very good subject and information gentlemen!

Greg,
  Now I'm not so sure about this ...I wondered about the large loads this
box was designed for; I can see (now that you bring it to light), how the large gears and bearings and thick oil would rob my little
stepper of most power- just to turn the gears. So I may not rush into a $50. purchase yet, until I can somehow actually test it's
torque with a wrench(Thanks RICH), the difficult part  is, a person can't test things from mail order or ebay.
  I will generally only be using 4th axis on items 1.5 " or smaller, I would like to put design or customers name
on lower barrel part.

Greg,
  Thanks for link and helpful information, I see that your red box is what I am looking to use
and I have found one in ebay at a reasonable price. 
  Now that you have been using yours with great success, if you could do it all over
again, would you choose a different ratio, or are you satisfied that the ratio you chose is
best suited to your application? (which is the same requirements I will be seeking!)
  I ask this because there are several different ratios to choose from, and 10:1 looks good
but will a stepper turn it?


RICH,   

Thanks for the tip-   
  I am going to have to get a torque wrench! This would be very helpful.

Hi Guys,
  I'm trying to find a less expensive way to make a rotary table,
would a 425ozstepper turn something like this, or would this worm gear have
lots of resistance? They seem to be fairly cheap compared to some of the rotary
setups I've seen associated with cnc.
  Thanks, Glenn
