  • head stock or steady rest chamber reaming

    I ran into an interesting and quite heated post over on "Practical Machinist" on the pros and cons of cutting chambers in either the head stock or a steady rest. I have done it both ways, and have had good results with both. Maybe we could get a less heated discussion here.

      If the barrel is long the enough I use the headstock, 4 jaw chuck and an outboard spider, if not the steady rest very simple. Either one is just as accurate if set up properly

        I am pretty flexible, The method I use depends on the lathe I am using at the time. I always cut the barrel tenon to size, with the barrel on a live center, then chamber with a floating reamer holder, weather in a steady rest or in a four jaw chuck. I know that is not the recommended way but it works for me.

          I have done it both ways, but I was taught to do it with a steady rest.
          the through the headstock is quicker and easier for me because I leave the outboard spider mounted on the spindle.

              Not wishing to be a smart ass, but isn't that the answer to a question that was never asked.

                I remember the absolute flame wars over lined versus unlined bores in bagpipes, or even which end of the egg to break. The solution seems to lie in one’s training, tooling, and the quality or success of the end result.

                  Well it does seem that the members here at HSM, are a bit more respectful of differing points of view, than they are over at PM.

                    My 10K has too small a spindle hole to take a barrel through the spindle. My Nardini has too long a spindle. I can only chamber fro the steady. With a suitable lathe I would chamber with the barrel in the chuck.

                      I use a steady as a last resort. The headstock on my Acer 14x40 is about as narrow as you'll find. I use a direct mount 4jaw and I cut the two steps off the jaws. I can do barrels as short as 21". Short than that and I have to do something different. It's not very often.

                      I just can't get a barrel indicated as close in a steady as I can with the 4 jaw and spider.
