Thanks for the leads Mike I'm getting close Zagnuts siw shooter is what I'm kinda looking for
I got closer last night turning up a prototype to see what tooling I have to make , I ground a Unibit down to match the taper and it sort of worked,
After seeng Zags Hub I have got a way to do it (I think) now.
I'll take some pictures as I go on the next one


Thanks much
