This system has several advantages over the common threaded spindle amongst which are a large center hole and freedom to run in reverse. One day I was having a hard time driling a large axial hole in a rather long piece of stainless steel. The lathe tailstock did not have enough travel and, anyway, was not designed for the kind of pressure needed to do the job quickly and efficiently. It would sure be nice to be able to use my big drill press. See photo Chuck_adapter3.jpg. If I could mount a lathe chuck as a work holder instead of the table, the job would be a piece of cake. I have two 3-jaw chucks, the 5" you see in Chuck_adapter4.jpg and a big 8"' job with comensurate center hole. I also have two 4-jaw chucks and a face plate that can all be used on the lathe or, with this adapter, on the drill press. I turned down a piece of 1 1/2" pipe to nicely fit the drill press table mounting hole and welded on a piece of rough cut (band saw) plate. I then machined the OD and faced front and rear of the plate to get good balance and true running. I drilled a hole in the center and bored it out to the ID of the pipe - just under 1 5/8". Next was machining the 100mm nose and laying out and drilling the three holes for the mounting bolts. Making the adapter and using it to drill the piece of stainless took less time than persevering with the abuse of the lathe tailstock. The adapter can be seen in Chuck_adapter1.jpg, Chuck_adapter2.jpg and Chuck_adapter4.jpg. It has seen much use since it was made a few years ago.
