A round hole in a square peg
I needed to make some square brass nuts to go with the screws that I
made earlier. Usually I would put some hex bar in the lathe to drill it accurately and chop off as many nuts as I wanted. I didn't have any hex bar and I wanted square nuts. I had some 5/8" square bar but I wanted 1/2" wide nuts. How was I to drill the hole accurately when I had only a three-jaw chuck? As it happened I was able to use the three jaw chuck like this: http://i50.tinypic.com/2uhlu88.jpg DSC00133lathe.JPG Then I milled the bar down to half an inch and the hole was in the middle! http://i46.tinypic.com/2f0bzfb.jpg DSC00134mill.JPG I finished tapping the hole by hand as the tap kept slipping in the lathe chuck: http://i49.tinypic.com/1zb70c5.jpg DSC00135tap.JPG Here's a finished nut on the screw that I made earlier: http://i50.tinypic.com/264rvap.jpg DSC00144nut.JPG Here's the screw and nut in place on the bell unit: http://i45.tinypic.com/2h4evxc.jpg DSC00137bell.JPG Everything but the screw and nut was cast in a foundry from an original sample. |
