    Thanks Doug, I will give it a go at posting the demag but this is not my area of expertise.
    I think I picked up the idea on the web somewhere and copied it monkey see monkey do fashion without fully understanding why it works.
    No doubt after posting someone will explain the theory.

    I used to make Fluidmotion Wheel Dressers at J&S Tool Co. You should get one of those someday. I could even tell you how to rebuild an old tired one, I think? It's been quite a while since I've done it, but I remember the broad strokes still. Enough of the process that you could probably figure out the rest. There is one odd piece of equipment you need to do a rebuild though. You need a rotary air table. You use that to resurface the base. But most of the rest we just did on a plain old surface grinder. Well, there is one critical part of the process that I don't know offhand. I don't know the diameter of the test ball we used. I mean I just used the things we had laying around. But thinking about it now I bet the size is pretty important. I suppose if you understood the geometry the size could be calculated? OK there's two odd items you need to do the build. Because I honestly don't know where you'd get one of those test balls even if you know what size it was. It was a carbide ball mounted on a stud that a diamond is usually mounted on. That's how we inspected the units. We'd mount the ball in place of a diamond and indicate the surface of the ball. If we could sweep the unit through its range of motion without moving the needle it was good. Neat huh?

    Sounds interesting pfredX1
    I bet those things were very consistent in movement and highly accurate as well, but the one I made will work fine enough for what I do, just setting it with an angle plate will be close enough for what I'm doing, I make all my angle plates with the aid of a sine bar and gage blocks and I can get them down to the nitty gritty pretty darn good,

    Would be an interesting tool to see though

    Thanks Doug

    Thanks Brendon, Much appreciated
    You know how sometimes you feel pretty confident about something? well this win I didn't feel that, to be honest I thought for sure your sled was going to win, that's where I had my money, of course the other guys had nice projects to but I was betting on you, you keep up the good work yourself as well

    Hey! Doug,
    I too, thought my sled might have had a chance, particularly given the link to my blog and the detailed post I did on calibration etc.
    We always live in hope I suppose.
    But you know, I got beat. That's the way it goes. There was stiff competition this week for sure.
    You're a damned fine machinist Doug, there is no doubting that. Well done and enjoy the moment.
