I recently purchased a 4” Vertex Rotary Table without accessories. I’m in the process of cleaning, deburring, and making accessories for it. My first project is makeing a MT2 stub and adapt a copy of my 7X14 lathe nose to it. I made the nose while trying to make a simple rotary table. The nose worked out, but the home made rotary table didn’t.
I need to adapt the nose to the stub so I can mount my lathe chucks, and even my face plate on the Vertex.
Not having an engineering background, I have a couple questions for the more experienced.
The unturned portion of the stub is .827”. The current hole in the nose is .467” I made it to fit the shank of a bolt I used to mount the nose on one end, and a 60 tooth change gear on the other, and it also fit the bearing I used.
Obviously, I need to make these two fit together. Should I enlarge the hole in the nose to say, .500, or larger, and turn the stub to fit the present hole? What would be the advantage of either, other than it would take less time to just turn the stub to a tight fit with the current hole in the nose. Is bigger better?
I don’t have any reamers, so I would have to make one out of drill rod (silver steel) which the largest I have is ½”. A bigger hole would mean boring.
