Doug when I bought my drill about thirty years (Taiwan manufacture) ago the first thing I looked for was there a hollow in the quill to the centre of the pulley that would enable me to use a locking threaded rod to hold the drill chuck in place. Then I got the Taiwanese motor and threw it away and fitted a 1 hp motor Aussie made. Stripped the quill etc fitted good bearings threw the others in the bin. Countless thousands of drillings later the drill is giving accurate holes with no problems, have not varied the speed ever it is quite fast.
So I enjoyed seeing your restoration and I know it is much harder on an older drill to strip down, clean etc as you have done.Thanks again for the blow by blow description.
Peter.
