    Hey Dean,

    There is another thread that someone posted a link to a person who made a RT. Ive copied the link and posted here. If I was going to make a RT, I would probably find this very helpful. The guy did a tremendous job.

    It's a good thread to read, I skimmed through all 15 odd pages last night. The only thing I would have done is supported the far end of the worm, although with such a small table it probably wouldn't be such a problem.
    I am working towards casting again, I have done ally and brass before but would like to do iron. Rt base here I come....(albeit very slowly) I have a burner now I need some refractory and a bagful of time......

    Hi Ueee,

    which thread is your burner in again? Are there pics of it? Is is a forced air or naturally aspirated?

    I want to make a burner soon too. Would love to make a used oil/diesel burner but an LPG sounds like the most sensible approach for a beginner like myself. Are you casting with petrobond type stuff of greensand?

    Cheers,

    Simon

    Thanks for that link Simon. It just happens that I was searching my history for "rotary table" last night and guess what came up. Yes it is a very helpful build. Arnold does a good job. I am currently reviewing all the pages I have found in the past.

    Spent today fitting the canopy for the new ute ready for a trip to the big smoke in the morning where I am going to pick up some truck brake drums and slack adjusters courtesy of rascal, among other things. So I have not had a chance to even think about shed stuff.

    That will be good to see Ewan. What size RT are you thinking. Will be a sizeable pour. I am going to stick with ali and brass for a while, if I get some more done that is lol. I am going to go with waste oil as I have lots of it saved up. It is cheaper to burn it than dump it.

    Regarding support for the far end of the worm, one thing I am wondering is whether the commercial ones have support for the main shaft at the bottom. I would like to provide this.

    Support for the far end is a problem as on the commercial ones the worm is on an eccentric so it can be disengaged. Not saying you couldnt make the "carrier" long enough to support both ends... just that its not on a 10" vertex.

    It's not on the 8" either, for reasons outlined by Stuart. Not sure it's really that necessary, the worm is not that long and they are hardened so would not think there would be much flex or movement. If you are only using it for indexing them you are not loading it up. The Vertex 8" states (assume its the same with all of them) that machining should only be done with the hand wheel rotated in CW direction although I thought this was more because there is only one "thrust bush" on one side of the worm. I replaced mine with 2 thrust bearings. HEY! Stuart, yours already came with thrust bearings as standard!

    Michael,

    somewhat belatedly I looked at this thread. I got here from a recent post. I am somewhat interested in the camlock adaptor for your indexing head. Any chance of a photo when you get the chance?
