Yeah, I enjoy doing things differently, as for showing you folks my set up, I cant. As this is almost all theoretical the setup anyway, meaning, I do not have a 3 jaw set up, nor is it mounted to a plate as I envisioned.
The tool doing what it is doing is really happening.
Due to the length of the tool and the stroke limitations of the machine it is quite an interesting challenge to hold the part in the vise, which inherently leads to issues as I must hold the part in the vise with the jaw of the vise nearly completely open and spacers against the back jaw of the vise to mimic the proposed setup. Now the part is not moving but I think cjtoombs hit the nail on the head so I will try that this evening. I had also thought about turning the tip over and cutting at the top of the bore. I will reserve that for the last ditch effort.
As for my tool, I ground it to a with of .157 on my surface grinder with 1/2 degree side clearance on each side. I machined the groove in the holder to .158 so that thing would fit nice and snug with little slop. I see this first tool as nothing more than a proto tool to verify that I can do what my mind says I can and I will go from there. The info I am getting confirms my thoughts of potential issues. As for locking down the clapper, I see no means for that so something else to keep my mind going.
I will make a video of what I do have setup and post here soon, will also be ordering the chuck today as well.
Regards
Richard
