Hi to All,
I’d like to compare notes on the issue of head stock length and how we work with …or around it related to cambering. For sometime now I’ve done it with the aid of an adjustable center that’s mounted on the back of the spindle and can be adjusted for length, to hold the barrel on center inside the spindle. My mentor built this a few years ago and it works great but takes a long time to set up correctly. I have seen and heard of many others that use this type of method to get around the long spindle issue. Some even use delrin bushings. Most of the internal center remedies require that true centers be cut after the barrel is cut to length to make weight. This is similar to doing between centers but you know have the 4 or 6 jaw to work with, a big plus for me, may not be for others. What if you use a cathead for the back of the spindle and mark the barrel for the cutoff points but only cut the chamber end off, leaving the muzzle end long so it would go through the spindle. (May work with spindles a little to long, but may have to use a cats head at both ends of spindle for longer ones.) All chamber end work is done with the through spindle setup. After chamber end is done, cut barrel off on the muzzle end mark and crown. At this point what will be the simplest way to crown? Between centers or with the internal center and or use a 4 or 6 jaw to drive the barrel and a cats head to run the steady rest on or maybe the long tube cathead driven by the chuck and also to run the steady rest on. Did I leave one out? The Question, if your lathe spindle is a little to long, is it worth it? The set up is very easy and the results are very good using the through spindle method. Then use an alternant set up to deal with the crown. What are your thoughts on this?
Thanks, Jim M.
