Ball Turning Simplified With The Aid Of Saddle Stops.
Probably of little interest to those with DROs but to others, maybe?
I have been trying to make a handle similar to that used by Multifix on their retractable threading tool. The handle is very much like that used on their 40 position toolposts in that it incorporates a broached 12 point through hole at an angle through the ball end. The ball had been causing me grief and the 4140 I chose to use was probably a contributor along with the not so easy to adjust ball turner.
The handle below is version 3. Version 1 couldn't really be described as a ball and version 2 became scrap when it pulled out of the chuck.
Success was achieved when I used a stop on each side of the saddle. The stops were locked against the saddle when the cutter was at 90 degrees and centred on the 20mm long and round section of the bar. With a live centre in place, the left hand stop was loosened and moved towards the headstock along with the saddle facilitating cutting the left hand radius. To cut the outer end of the ball, the left hand stop was re-positioned and locked with the saddle hard against the right hand stop ensuring that the cutter was again centred on what remained of the 20mm long section of the bar. With the right hand stop moved out of the way cutting the radius on the unsupported outer end was done with extreme caution. Nothing went bang.
