Re: [CAD_CAM_EDM_DRO] LOOKING FOR PLANS FOR SOUTHBEND TAPER ATTACHMENT FOR 9" LATHE

Hi Stan,

I don't know what a Southbend Lathe looks like but I have had many lathes over the year starting with a table-top and working up to the Viceroy I use these days. I have always used the same basic design of taper-turning attachment which consists two brackets with a bar between them. One end of the bar is fixed and the other is allowed to move through a small arc via a thread of 40 tpi. There is 25 divisions on the hand-wheel, each division moves the bar 0.001" approx. I say approx because it is travelling through an arc not a straight line. The bar is 12" between fixing points as taper is usually measured in inches per foot. A slider runs along the bar. the slider is attached to the top-slide of the lathe by a bracket, with the bracket being long enough so that the mid-point of the bar coincides with the mid point of the travel on the top-slide. Cut is then applied using the compound-slide. The top-slide lead-screw is of-coarse disconnected.

None of this is necessary if you convert to CNC.

Regards,

Terry


Has anyone here adapted something to make a taper attachmet for a
southbend 9" lathe?

Can someone give me the overall lenth of the cross-slide. The rest I can
figure out.

Thanks
Stan
