Turned out really nice Mark. Much better than the one in the kit. Personalised the tool. Cheers Nobby

Are you able to set the tool to the correct radius and in the desired position from the end. Then add the cut depth with the cross slide until you are over the centre. It seems easier than moving the radius every time.

[@EnglishHobbyMachinist]

@@machinists-shortcuts I haven’t tried to do it that way, but whatever method is used involves moving something each pass 👍

It looks like a no brainer to me and ideal for repeat balls. It will be easy to set the zero at the end of the crossslide travel. Do my head in picking up the allen key then finding the hex hole then unlocking the slide and adding a cut then putting it down again and remembering to lock the slide. Id add a cut with right hand crossslide handwheel and move lever with left hand keeping pressure on the crossslide handwheel to prevent moving when cutting. With the radius set and locked no danger of going smaller even if you go past the center of the part.
Would a round carbide insert work screwed to the end of a bar instead of the hss tool. Having it slightly larger than the rod would give it a natural clearance and would not need to be set at an angle.

@@tates11 thank you for comment, your knowledge is far superior to mine, but I can’t see how it would work using the cross slide in it’s current configuration of cutting at the top and centre of tool rotation is centre of the tool holder. Maybe my lack of knowledge won’t allow my brain to see it 🤷🏻‍♂️

[@tates11]

@@EnglishHobbyMachinist It looks like the tool engagement would increase too much as you get nearer the center. Like you said in the video adding a pair of chamfers may be needed to rough out the profile. Not as simple as it first seemed, but might be worth a try for interest, maybe try approaching it with the compound at 45 degrees.
