Hello, Thank you for the reply. I think I need to brush up on my maths!

I had a chance to have a 'play' today and it leaves a flat part at the edge going in about 2.5mm
Like you I have the woes of lead screws Harrison saw fit to have them from new, hmmmmm.
Ball screws are on my wishlist though.

It also cut from edge to centre. Just to rub it in there is a video of my lathe from a previous owner machining a dome a treat and I noticed he managed to get it to do it from centre out. http://www.edproject.co.uk/CNClathe.html

I am going to try and get in touch with him.

Hello, Thankyou for looking into it.

My Version R3.043.062

It is not a hemisphere I am after. Imagine a pizza, If I cut it in half I get a hemisphere around the edge of the crust.
What I am after is the curve you would get from the pizza being cut into segments.
I.E something shallow you could create with a file on the end of the stock.

Hello to all on this forum, I hope you can help a nOOb with a headache.

Could you please advise me on which wizard would be best to make a simple dome on the end of bar or bolt heads etc.
I have tried OD Fillet 2 and OD Arc for ages with all the settings I thought made sense to a manual lathe man but no luck.
I think no luck as none looked right in the toolpath window.

My goal is to start cutting at the centreline outwards to around -2mm z at the outer edge. Creating a shallow curve.
Any help in layman's terms would be great as I have only been into CNC a week.
