Watched the video and it shows a sorta cage on top of head which is along the lines of that that I came up with, it'll do the job, but its somewhat awkward in my opinion, wanted something more self contained. Hadn't seen the SPG Tools offering but the power drawbar looks more industrial than hobby, I don't have air and the cost is way to high.
Muzzer, the Tom Senior will do for me, it's not going to get changed, whether or not its got the 'correct taper' LoL
