It's a 2 inch radius Craig.

Yes Joe your description of my desired operation is far better than mine. I must have reached the crossover point between what a wizard can do, and when Cam becomes necessary. I will just use a V pulley for the lower part of the die, and make the top bit by drilling a 1/2 inch hole in a piece of rod and bisect it.
Thanks for the reply.

Hi all
I need to make a pipe bender die for 1/2 inch tube, to bend the tube to a 2 inch radius. I assumed there would be a wizard in mach3 turn that does this, but cant find one. Basically it is the mirror image, or reverse of the Od ARC3 wizard that I am trying to achieve. I want what appears as a raised section on the wizard diagram, to be the lowered section with the same dimensions.
I was hoping that someone would know of a wizard, or a method of doing this
Thanks
David

Cheers Rich, but in your message yesterday, you said "If all you want to do is put a radius on the end of the stock use a different wizard" I realise that trying things is all part of growing up, but I think that over the last 10 years or more I have had the opportunity to try most of the wizards included in Mach3. I don't recall one that puts a radius on the end of a shaft. I thought that since you made the statement above, you might have known of one.
Regards
Dave

Thanks Rich, that's as I thought, but I had a vague memory of it working despite the garbled graphic. I hear what you are saying about the unsupported wizards, and you suggest that I use a different wizard. Which wizard specifically would you suggest? I am happy to use anything that works. What would you use to put a radius on the end of a job? Other than a file of course.

Switching between Radius and diameter mode did not fix the issue. Here is a screenshot of the problem, the first is the issue, which happens after I increase the radius or diameter by 1 mm. The second is the ok version.

Thank you Rich, sadly I have tried most of the points that you mention in your PDF, although I hadn't tried switching from radius mode (my current mode) to diameter mode instead. I have made the nuts that I wanted using the OD fillet2 wizard, but for the future, I'd still like to get my head around the OD  Arc wizard.
Given that my preview screen is messed up when I use a sphere diameter larger than 29mm, (my job is 20.4mm diameter, or 10.2mm in radius), I suspect that perhaps changing to diameter mode might resolve at least this issue.
Thanks again
Dave

Actually, I was searching for, but didn't find, some doco that covers the turning wizards. Does such a thing exist?

I am trying to use the OD Arc wizard under Mach3 turn to cut a radius on the end of a rod. Here is the scenario:
I have a piece of hex bar that I want to cut a radius on the end of. I am making a few wheel nuts.
The bar is 20.4mm across the points of the hex. I want a radius that is 3mm below the edges of the hex, and covers all of the end of the bar. I am fairly sure that I have done this type of thing successfully in the past, and I seem to have in my mind that I specified a sphere diameter that was larger than the end of the bar, then used the graphic in the wizard that shows where it will cut, to fine tune the arc until it covered the end.
I am using these parameters: Z center 0, Z start 10.2, Z end 7.2. X start 10.2 X end 0
With the sphere diameter set to 20.4mm, the wizard does what I would expect, and proposes cutting a 1/2 sphere, finishing 10.2mm down the nut.
If I put a larger sphere diameter into the wizard, the image on the screen in the preview, is nothing that I am able to understand.
