i have seen them used but have no experience myself, didnt ever need one. what should they do, let the tool move radially, at an angle or both?
i figure if the reamer is alowed to change its position from perpendicular and is offset you get a conical hole. on the other hand i see a lot of contraptions bolted to the tail, mainly in gunsmithing, that do exactly that, to compensates for bad alignment. doest make sence. if you do work like that you see to it that the tail is aligned in the first place. there are units that seem to alow radial displacement only. that makes more sence, at least to me, and has its use where you move the work from one machine to the other.
